[Guide] Email Marketing for E-commerce

E-commerce is growing at an astronomical rate. In 2017, global e-commerce was responsible for $2.3 trillion in sales, and this is expected to grow to $4.5 trillion in 2021. That’s why, if you haven’t done it yet, it’s time to review your e-commerce email marketing strategy.

Alongside this growth, all signs point towards emailing as the preferred method of communication in e-commerce over other channels, including social media. In fact, 72% of people, (including those elusive millennials and teenagers) still primarily prefer email as their primary mode of communication with brands.

In this article, we will give you everything you need to get your e-commerce email marketing strategy up to par, including the different types of emails you’ll need in your customer journey, and essential tips to get content, design, data, and deliverability right.

Email marketing strategy: The essentials

Before you send a large number of emails to your customers, it’s important to define your email marketing objectives. After all, to build a house you need a solid foundation. Your objectives will be your foundation.

Writing emails without a solid strategy will run the risk of sending campaigns that aren’t relevant, and that can result in a low click rate or worse – skyrocketing unsubscribe rates. You don’t want this, do you? 🤔

The key question you should be asking yourself here as an e-commerce company is: What do I want to achieve?

Your objectives could include:

  • Converting new customers
  • Increasing sales
  • Receiving reviews and feedback
  • Boosting customer loyalty and communication
  • Providing customers with information (about special offers, new products, etc.)
  • Introducing your company and your unique selling points


KPI Framework

Of course, you don’t have to pick just one of these objectives, but it is beneficial to have just a few clearly defined objectives. Concentrate on those most important to you, your business, and where you want to grow. This will allow you to utilize your resources efficiently and also means you won’t waste unnecessary time creating email content that provides no added value.

Instead, ensure that your email campaign is perfectly tailored to your needs. Follow a clear objective that you can naturally adapt, modify, or realign over time.

Email marketing tips for e-commerce

Within each of these campaigns, you always need to keep in mind the 6 key elements of any email strategy: content, design, data, tactics, personalization, and deliverability. To get right to the point, we’ve outlined what you need to consider in each email and included some examples (as well as cautionary tales) to help you with your own campaigns.

1. Spend time on your email content and design

Working on your email content and design should be one of your main concerns in your email marketing strategy. An unengaging subject line won’t entice customers to click on your emails, while poor design reduces the chances that your customers will find the right product for them.

What you want is to first optimize your subject line and preview text. After all, they are the gateways the first things people see in deciding on whether they should open your email or not.

Opt for subject lines that generate curiosity. This will make the reader feel they are missing something “valuable” and want to click into that email to find out more. Which fabric is in-season? What are those fresh finds? This is very effective marketing tactic. However, each “preview” text is simply their URL, www.etsy.com which is a missed opportunity to engage the reader some more.

Good content does not rely just on being creative, and good design isn’t just about being beautiful. Good content is about personalization and timeliness. Good design is about inciting an action.

This is especially impactful for e-commerce where a sale is just a click away, and good content paired with good design can effectively drive clicks.

This Black Friday email by Julep fulfills the basic rules of smart email marketing by knowing how to sell what it wants to sell, writing creative, holiday-oriented copy and ensuring responsive design across all devices and inboxes.

Julep - eCommerce Email
Julep Email Example

The header immediately introduces the email content (hint: it’s Black Friday sales!); the multi-column design blends image and text into creating compelling copy that guides customer attention. The Call-to-Action (CTA) button (SHOP NOW) also is strategically placed above-the-fold alongside the content. Customers don’t have to scroll down to see these great deals ($19.99 instead of $82), inciting them to click on the CTA.

2. Know the difference between marketing email, automated email, and transactional email

Learning the different types of emails will not only allow you to target different audiences, but to also target the same audiences in a variety of ways. Sending identical promotional emails every single time with just slightly-altered copies can quickly lead to a smash of the unsubscribe button.

As with all marketing efforts, email-marketing should be diverse and creative. As an e-commerce business, you will be sending three main categories of emails:

  • transactional emails
  • marketing emails
  • automated emails

Transactional emails are the types of emails you send out to customers after they’ve done an action. These emails can be purchase confirmations, account verifications, or password resets.

Harrys - eCommerce Email
Harry’s Razor Transactional Email

This confirmation email by Harry’s does its intended job and more. In addition to ensuring that your order has, indeed, arrived, it’s also included some quick shaving tips for customers to read. Beyond just trying to drive sales, they’re trying to drive engagement, loyalty, and through education they are growing their connection to their audience.

On the other hand, marketing emails are bulk emails you send to your subscribed customers. This marketing email from New York & Company contains two types of promotions. The top section includes coupons encouraging customers to spend more to save more. The email’s main body introduces the arrival of their new collections by introducing a sale on their kimono sleeve sweater, for that perfect autumn aesthetic. Get creative and create value where customers had not seen. That’s showbiz marketing baby!

NY & Company - eCommerce Email
NY&C Email Example

Finally, automated emails are triggered by milestones. They can be automated in many ways, depending on your analysis of customer data. Automated emails can include welcome emails, feedback emails, anniversary emails, and retention emails. For example, if a user purchased a product from your store, you can send an automated email one week later to how they are liking it, whether they would like to buy one for a friend, or perhaps write a review on your site.

3. Avoid mistakes before sending

Of course, when you’re new to sending these different types of email, you’re bound to make a couple mistakes, or miss out on some things. To avoid that, send yourself a test email to ensure everything displays properly, that there are no typos and that the email is responsive.

Before sending emails or committing a template, make sure to pull your teammates into the email builder to have them provide their comments, and be sure to A/B test your campaigns to identify which piece of content, design, subject line, or CTAs drive the most engagement.

Don’t send emails from a useless “no-reply” address. “No reply” emails are those annoying emails you get from businesses sometimes who are making it very clear they don’t want to hear from you.

NoReply Inbox

Not only is it a little rude, almost more importantly it can negatively impact your business as it is often flagged as spam.

4. Don’t ask for subscribers, incentivize subscription

Before sending emails to your customers, you have to make sure that your customers have subscribed to your emails in the first place. There are a lot of different ways to do this.

For example, you can invite website visitors to subscribe to your emails via pop-ups integrated into your website using Mailjet’s subscription widget or third party providers like SumoMe. Or like many of our customers have done so effectively, use the power of social media to invite customers into your mailing list.

Good Things - eCommerce Email
Subscription Widget Pop-up

One thing that you need to include is an unsubscribe button in your channels. Yes, adding this will mean your list may decrease in size, but more importantly it lets your audience do the different work of cleaning your contact lists for you. By removing customers who’d rather not see your emails, you are ensuring that only those most active engaged users are being sent an email.

In turn, this means you are:

  • Spending less money sending emails to people who won’t open them anyways, or worse would mark it as spam.
  • Increasing your domain and IP reputation with ISPs and inboxes.

Unsubscription Email

One of Mailjet’s enterprise users, Videostream, knows the value of this all too well. With the help of a Customer Success Manager, Videostream cleaned their list from 1.2M contacts to 120K contacts. This 10x decrease in users actually resulted in a 5x more total opens, and an increase in ROI of 10x.

This is because the more people receive unwanted emails from you, the less likely it is you will land in the inbox of those who do in fact like you. Here’s a full case study on how Videostream accomplished this.

5. Track and use your data

Data should serve as the bedrock of your email marketing campaigns. Considering different buyer personas and the customer lifecycle in your email marketing will allow you to send the right email to the right people. Whether it is creating promotional holiday emails, or segmenting people into different groups, data will help you send the relevant emails to the right people.

Email Stats - eCommerce Email
Mailjet Email Stats

Useful email metrics to consider when using Mailjet’s platform include how many emails have been sent, delivered, opened and clicked.

The sent rate is a way of saying that the recipients’ servers have received the emails, and the delivery rate means that the recipients can now read them…somewhere (in their inbox? Spam? Mystery. Well, kinda.). The opened rate shows how many people have opened their emails, and the click-through rate shows how many times your customers have clicked on a link in your emails since receiving them.

Other types of data that you want to track, of course, are related to the types of customers you want to target. Getting actionable customer insights will help you send the right types of emails to the right segments, and create engaging, personalized emails.

6. Optimize your e-commerce email marketing strategy

Even the most successful email campaign can be improved. So you need to keep testing your performance.

Ask yourself these questions and adjust your content accordingly:

  • Which email subject line has the best opening rate?
  • Which links and call-to-action buttons generate the most clicks?
  • Which email content was uninteresting for your subscribers?

You can use A/B testing to compare different types of content and then see which alternative was received most positively by your customers.

You can use a tracking function for a step-by-step breakdown of if and when an email has been opened, and which links and widgets were used. With this knowledge, you can improve and adjust your future campaigns.

Segmentation can also be carried out based on this evaluation. You can send personalized email content and build an optimized list of newsletter subscribers.

7. Work on your deliverability

Improving your deliverability – the rate at which your email reaches your customers’ inboxes – is of utmost importance to ensure that your emails do not go not into the spam folder, where emails go to die.

Essentially, all of the previous tips lead up to getting a higher deliverability rate for your e-commerce business. Creating compelling, data-driven email copies will increase the open rates and click rates, which improve your sender reputation. Your contact list should be constantly updated and adequately segmented so that the right people receive the right emails.

To get high delivery rates, have a good, reliable email service provider (like Mailjet). There are many marketing platforms that can send your emails, and have become particularly good at providing both a CRM and an email system, however these tools are often good at a few things but are simply not as strong in email deliverability as an email service provider can be.

This is primarily because good deliverability requires three things that take time, resources, and a commitment to email:

  • Strong and on-going relationships with inbox providers.
  • A robust infrastructure and third party vetting tools like Mailjet’s partnership with 250ok.
  • Deliverability experts to help maintain quality domain and IP addresses for senders like you.

On your side of the equation, you will need to enable your Sender Policy Framework (SPF) and Domain Keys Identified Mail Option (DKIM). These allow your ISPs to recognize the fact that your emails come from a reliable, authorized system, and prevent spammers from stealing the identity of legitimate identities. Mailjet provides an easy-to-follow guide to do this.

E-commerce email campaign ideas along the customer journey

As an online shop, there are many types of emails that you could send out. In order to make the most of all email marketing potential, we recommend integrating marketing and transactional emails along the customer lifecycle.

The benefit of focusing on the customer journey is that it allows you to deduce current customer needs and create personalized content.

Here are the seven different email campaigns you should use, depending on your objectives and customer journey:

1. The welcome email

No matter what, first impressions really count.

When welcoming a new “member” to your email list, send them a welcome email containing valuable content that will inspire them to continue to engage with new articles. For instance, this is a great opportunity to:

  • Introduce your company and your products.
  • Make the subscriber aware of your social media channels.
  • Provide an overview of what type of emails you will be sending.
  • Send them a welcome gift to validate their decision to subscribe
  • Indicate important links.

Ultimately what you want is to convey a positive and trustworthy first impression, which will make your new subscriber look forward to receiving more.

2. The classic newsletter

Once you’ve won over new subscribers, you need to make sure they stay in your list by providing them with valuable content.

Naturally, the exact content depends on your business model and customers. As an e-commerce company, you can offer the following newsletter content:

  • Promoting your own products
  • Guides for your products
  • A behind-the-scenes look at production
  • Compelling content and entertainment like videos
  • Customer interviews and testimonials


Penguin Newsletter
Penguin Books Newsletter

Don’t make the mistake of thinking that your newsletter is only there to sell. Sending out newsletters that are too pushy will cause people to unsubscribe from your list, or put a bad taste in their mouth. Instead this is an opportunity to take an engaged list of potential customers and make them love you.

Ask yourself the following questions and create your newsletter accordingly:

  • What interests my readers?
  • What questions might they have?
  • What problems are they currently facing?
  • How, specifically, can I help them solving these problems?


3. Special occasion newsletters

In addition to your regular newsletter, you can create email campaigns for special events. These can be for holidays such as Christmas, Easter, and Mother’s Day, as well as seasonal events such as the World Cup, the Olympics, or Oktoberfest.

You could even, for example, showcase your expert knowledge in the form of useful tips and tricks, or make readers aware of special offers. However, make sure that it all ties back to your company and brand message.

4. Order and shipping confirmations

While you can send out marketing campaigns at any time, transactional emails are triggered by customer action. These include, for example, newsletter subscriptions, invoices, and purchase confirmations.

As an e-commerce company, your main objective is obviously to promote sales in your online shop. Once a customer buys something, you should first send them an order confirmation and then an email receipt. Once the purchased product is sent for delivery, you can then send them a shipping confirmation.

Transactional emails tend to have higher open rates, as customers already expect to receive your communications and look forward to receiving their purchase.

Make sure you leverage these emails to make your customers aware of other products or special offers. This is the best time for you to upsell, when they are most engaged and you know they are opening the email. Don’t miss the chance. 😉

5. Customer surveys

Show your customer that their opinion is important to you by sending them customer surveys and other feedback emails. This could target individual products, the entire shop, the service, or all of the above.

Customer surveys are absolutely essential to you for the following reasons:

  • To check if your communication with customers is clear and coherent.
  • To obtain and guide the attention of your customers.
  • To strengthen customer loyalty.
  • To inspire you with new product ideas.

6. Shopping cart dropouts

Has your customer halted a transaction or left an item in their shopping cart? Remind them with a friendly email! This gives you an additional option to show them similar products and offers, or provide them with buying incentives through discounts.

Dote Abandoned Cart Email

Don’t give up on any customers! You can send a personalized email to inactive users. This allows you to find out if they are still interested in your services and remind them about your unique products.

If you succeed in winning the customer back, you can surprise them with a “Welcome back” email. You can make a good impression here with the aid of discounts or coupons.

If you don’t receive a reaction following several messages, then it may be best to part ways and remove the contact from your list. Yes, we know it’s always hard to let them go… 😔 but it’s best for everyone this way (more on this below…)

7. Personalized note to your customers

You can engage your customers in a more personal manner and develop a friendly relationship with personalized touches such as a birthday email with coupon.

Think about whether you would like to show appreciation to particular customers – after all, loyalty should be rewarded! For example, cheaper account upgrades are a possibility here.

While we’re on the topic of rewards, you may want to provide incentives for customers and subscribers who recommend you others. Make it easy to recommend your website and shop, and show your appreciation for each customer gained this way.

Summing up

You are now ready to make the most of email marketing for your e-commerce company. You know you need an effective email marketing strategy, how to create and manage email lists, and which types of emails are just waiting for you to use them.

Remember these top email tips for e-commerce businesses:

  • Tip 1: Marry good content with smart design to drive customers towards your products.
  • Tip 2: Learning different kinds of email will really allow you to take advantage of email’s sweet ROI. And don’t do no-reply emails. It’s bad for business.
  • Tip 3: Take multi-channel approaches to incentivize subscription. But make it also easy to unsubscribe to make sure that you’re not sending emails to people who will never read your emails.
  • Tip 4: Tracking data on customers and email will help indicate what works and what doesn’t.
  • Tip 5: Personalize and segment your email campaigns, putting in that little extra effort on each campaign and in data collection will go a long long way in standing out from the crowd.
  • Tip 6: Make sure your emails don’t go in the spam folder by sending emails smartly and following the previous tips.

Emailing for the Banking Industry: Data Privacy and Deliverability

Emailing has proven very effective in virtually every industry right across the board. This is especially true in the financial and governmental sector, where banks, insurance companies, neobanks and fintech companies send millions of emails every day to communicate with current and future customers.

However, the growth of email in this sector means there are new challenges to face: making sure that emails reach the inbox while ensuring the highest standards of data security and privacy. In this article, we have set out the techniques for optimizing your deliverability and achieving a high level of data privacy and security within your organization.

The importance of emailing in the banking industry

The banking sector has seen a noticeable rise in the use of email. With the increase of social awareness around the use of paper, financial institutions have been going paperless and looking for other more sustainable ways of communicating with their customers, such as email and mobile apps.

There’s several reasons for the popularity of email in the banking sector:

  • Everyone has an email address: Nowadays, having an email address has practically become an essential, making it one of the most widely-used means of communication, especially for important messages.
  • It’s instant, but can be saved for later:Banks can message their customers instantly. Also, the messages remain in the inbox, which means recipients can go back and read them at a later stage.
  • Personalized emails can be sent to scale: A reliable email infrastructure lets you send large volumes of personalized email with each customer’s individual information, such as month-end transaction summaries or quarterly charge notifications.
  • It’s affordable, easy to use and offers concrete metrics: The simplicity of email and the variety of information available to marketers make this method a perfect tool for sending marketing and transactional communications.

However, digital transformation also poses new challenges for the banking sector. Financial institutions must be sure that the critical messages they send by email are not compromised and that they reach the user’s inbox.

How to ensure a high level of data security and privacy in email

According to the study carried out by Capgemini and the EFMA in 2019, 76% of senior executives say that one of the biggest worries for the banking industry in the new digital age is the privacy and protection of their customers’ data.

As part of a company that deals with money and people’s personal data, you know that your organization should not take security lightly. It is essential to protect confidential information and avoid cyber attacks or data leaks.

That’s why email, as one of the most popular channels for direct and personalized communication with your customers, must be secure and guarantee that all data is safely stored and only available to those with access authorization. It’s important to remember that inboxes have become places where those with harmful intentions seek out their victims and exploit their weaknesses.

What regulations must my company comply with?

Of all the emailing agreements that you need to comply with, the most important is the EU General Data Protection Regulation (GDPR). 

GDPR came into effect in May 2018 and regulates the processing of European citizens’ data. It applies to all European and non-European companies whose customers live in the European Union.

If you are still unsure about the requirements of this regulation, we have prepared a kit with all you need to know about GDPR that will help you achieve compliance within your company.

However, it is not enough to ensure your own company’s compliance; you must ensure that your service providers also comply strictly with the regulations, especially if they deal with data and confidential information.

Third-party providers are often the weakest link in a company’s ability to be GDPR-compliant. Email service providers pose an especially high risk as they regularly process and store a large scale of personal data (example: first name, email address, IP addresses) on behalf of enterprises. That is why compliance from the entire processing chain is so important today.

Techniques for improving data security and privacy

Data privacy and security are also a major concern for your customers. According to an IBM survey, 81% of consumers are concerned about how companies manage their data and 87% think that companies need to tighten their personal data management policies.

To help your organization to ensure optimal data security and privacy, we’ve listed the two main techniques required to achieve a firm foundation.

Server security and data storage

Firstly we must make sure that the servers on which the data is stored are secure.

If it is your own company that is responsible for storing this data, it must be, at least, GDPR compliant. Provide continuous surveillance of the servers and limit the number of people with access to them. This is mandatory for your business, and it is key for the protection of your users’ information and for their continued trust.

If the data is stored by a separate company, keep in mind that your chosen provider must offer all the guarantees. Redundancies, fire prevention, high security levels, energy self-sufficiency, etc. As you will not be the one directly managing the server, you must ensure that all preventive measures required to guarantee the maximum level of security are followed. If you have European customers, it might be a good idea to also have servers in Europe, as the strictest European laws will apply.

The choice between relying on your internal email infrastructure to manage your email requirements or outsourcing to a third-party service can be a difficult decision. To help you find the best solution for you, Mailjet has created this guide, which looks at everything you will need to consider and gives a detailed explanation of the three solutions available to you.




Encryption is the most common method for protecting emails and the information that they contain.

Despite what most people think, the DKIM protocol does not provide message encryption, although it does add an authentication layer which helps to protect your messages. When you send an email using DKIM, the receiving servers will check it. They will use your public key to verify that it matches the private key included in the DKIM signature. If it does, it means that the domain name sending the email is legitimate, and the sender’s identity will consequently be validated and the email decrypted. Otherwise, the email might be treated as a phishing attempt.

To protect your emails, Mailjet encrypts the channel by which your emails are sent from your sending server to the recipient’s server. This is done by the Transport Layer Security (TLS). However, not all internet providers use TLS, which means that if you send a TLS encrypted message to a server that doesn’t follow this protocol, this type of encryption will not be effective.

How to achieve world-class deliverability

If you are a financial sector organization, the security and the privacy of your data are not your only concern when it comes to emailing. Reaching your users’ inboxes has become both a challenge and a priority.

If your organization uses email as one of its internal or external communications channels with current or future customers, you must ensure that they are receiving your emails in the right place (inbox) and at the right time.

What is deliverability and why is it important?

Deliverability refers to our ability to deliver an email to our recipient’s inbox.

Did you know that statistics show that around 20% of emails sent do not reach the inbox?

Deliverability is undeniably a basic consideration for any company sending emails and especially for those dealing with relevant, financial and personal information such as in banking, insurance or fintech businesses. Information that must be delivered on time and at the right time. And, of course, the privacy and protection of your customers’ data must be respected.

There are many practical examples in your sector where deliverability, security and privacy go hand in hand. These include purchase or bank transfer confirmations, transaction authentications, the sending of confidential documentation such as contracts, policies or summaries of a customer’s position status, or welcoming new customers to your services. Take a look at this example from ClearScore:

Email Clearscope

Even something as simple as delivery confirmation of a package containing a new credit card, for example, needs to reach the inbox at the right time. A good example is this email from Barclays:

Email Barclays

Finally, there are communications that should literally be instantaneous, especially transactional messages. Email will allow you to do this better than ever, if you have a good email service provider like Mailjet, of course. Although the best way to cover your back is to add transactional SMS to your triggered emails, as these have a 98% opening rate.

Techniques for improving deliverability

Improving your company’s email deliverability is a task that requires dedication and consistency, so your team should work consistently and always observe best practices.

Here is a summary of some techniques that will help you to maintain deliverability at optimal levels.

Use a subscription form to create your lists

Good emailing practice starts with a good list of contacts who are active and interested in receiving emails from your company. Your organization will need to follow these two basic rules:

  • Never buy nor borrow a contact list. This will have a negative effect on your current and future deliverability. These third-party lists are usually outdated and contain spam traps.
  • Use double opt-in.This way, anyone who subscribes to your emails will receive a confirmation email that they must validate in order to have emails sent to their inbox.


Regularly clean your contact lists

Contact lists change constantly. Some will subscribe to your emails and others will unsubscribe, change their addresses or lose interest in your company’s content.

Instead of sending them emails which no longer appeal to them, we recommend that you periodically delete these inactive addresses, as well as those addresses that return error notifications, blocking, cancellation of subscription or spam complaints after every marketing campaign.

This way, you will keep only those contacts who are interested in your services and avoid sending emails to people who do not even open the messages or to addresses that no longer exist. This way, your email statistics will skyrocket, ISPs will receive very positive signals and your deliverability will improve overall.

We recommend carrying out a thorough cleaning of contacts and we have created this article to show you how it can be done.

Have a WHOIS public profile

A WHOIS is basically your website’s ID card. It lets everyone know who is behind the domain name: technical and administrative staff, location of its offices, etc.

Having a WHOIS public profile is a guarantee for any internet user, including the ISPs, that there are legitimate individuals behind the scenes. If there are certified credentials, email managers are more likely to allow emails to reach their appropriate inboxes.

Configure your SPF, DKIM and DMARC

If this sounds like double Dutch to you, don’t worry, but it’s important that you know that your technical team has configured these protocols, as this will help the ISPs identify you as a legitimate sender. It’s good practice and, in fact, it is mandatory to do so as it will have a positive effect on your deliverability and ensure your deliveries.

To avoid going into too many technical details here, we have drawn up a step-by-step guide on how to do it that you can share with your technical team.

As you can see, deliverability is much more important than it seems. If you want more details, we recommend you download our ‘Landing in the Inbox: Deliverability Basics’ guide.

Email Marketing For The Travel And Tourism Industry

Ask anyone about their interests, and most people will probably mention travelling. There are so many people posting about their #wanderlust that it should be easy to beat your sales goals every month, right? And yet, with such a competitive market, it’s increasingly hard to turn all those eager travellers into customers. Lucky for you, email marketing is here to help you. 😏

In this guide, we will cover the fundamentals of email marketing for the travel and tourism industry and give you campaign ideas and examples for the most common scenarios.

Travel and tourism in the digital world

The Internet has forever transformed the way we travel.

Most people spend hours scanning the Web to find the best deals, riffling through tourist guides and leaving a trail of valuable data about their interests, budget and patterns, changing the travel industry in the process. The harder life gets and the more their workload increases, the more inclined people are to get lost in their own imaginary vacations.

Now, the ball is in our court. As marketers, we have the opportunity to grab these people’s attention. It’s not easy, though. Travel and tourism businesses in the digital world face two big challenges:

  • The customer journey is longer: There are many different aspects and elements users take into account when preparing a trip, so it’s important to map out that customer journey to ensure we have the appropriate touch points throughout the whole lifecycle.
  • The competition is tougher: The Internet is filled with multitude of travel providers and tempting vacation offers. Targeted customer communication is essential to stand out in such a crowded competitive landscape.

Choosing the right marketing channels to communicate with your customers is key to succeed in the digital world, and email should play a very important role in any omnichannel marketing strategy.

Creating a strong email strategy for the travel and tourism industry

We know it already, email is the best performing channel for ROI, ahead of SEO. It’s our job to use this endless stream of information to build a superb email marketing strategy that turns tourists all over the world from daydreamers into actual customers.

So, how do we turn a dull inbox into a real gold mine? We’ve got the tips and examples to help your create a winning email strategy for your business.

Define your email goals

It’s never smart to start sending emails out without clear objectives. So before you start building out your first campaign, take some time to think about your overall goals and your more specific ones.

It’s important to be as concrete as possible when establishing your overall goals, which will allow you to design specific milestones you want to reach with each campaign. For example, your overall goal might be to increase your sales by 20%. Your specific goals will help you determine the exact conversion rates you are aiming for in each email.

Build a healthy contact list

Before you begin sending emails, you need to build a list that has the potential to convert. That is, a list of contacts that are interested in what you have to offer.

At Mailjet, we believe that success lies in growing your list organically and not from buying data. The prospect of starting your contact list from scratch might be daunting, but it is key to get the best results.

Asking for consent to send marketing emails ensures users are interested in the content we send, and is also key to comply with data protection regulations, like GDPR. At the end of the day, spending your budget by sending emails to people that are not interested is just a waste of money.

Conquer responsive email design

The way we browse the Internet and interact with companies online has changed, and so has the technology we use to read our emails. Now, we use a range of devices (tablets, smartphones, wearable…), all of which have different sized screens and display messages in different ways.

When designing templates, it’s essential to keep these different screen sizes in mind. Responsive designs are those that render properly and deliver a consistent message, regardless of your contacts’ device or email client. Your template and your beautiful images, key to take your reader straight to their dream destination, should adapt to the device they’re being viewed on, or they won’t be effective at all.

Use customer data to send better emails

Understanding why your customers go to your website, their interests and budgets is essential to produce emails that are not only relevant, but also targeted to each and every one of them. Gaining insight from what they book, when they do it and how much money they spend is priceless information that will allow your email strategy to go from good to great.

Nowadays, there’s a huge amount of data available for email marketers to use, although we don’t always make the most of it. Here are a few ways data can help you build more meaningful emails:

  • Segment contact databehavioral data and data based on your users’ previous interactions with your website to better target your customers and to send them contextually relevant emails. There are many examples on how to use segmentation, like targeting contacts in Northern Europe with a campaign about warm destinations, or encouraging big spenders to book a luxury stay at your hotel.
  • Personalize your messages to engage with your customers on a one-to-one basis. It’s not just about the simple things, like including your contact’s name in the subject line, but also about using tools like dynamic blocks to tailor the content to each and everyone of them.
  • Use A/B tests to compare the performance of different versions of the same emails. The opportunities are endless – from the basics (from name, subject line, CTA) to aspects such as personalization, content, design, sending frequency or even sending days and times.


Integrate marketing & transactional emails

Before, marketing and transactional emails used to be handled independently. Nowadays, though, companies are expected to offer a seamless customer experience across both marketing and transactional emails. By making sure your marketing and transactional emails have the same look and feel, your customers will know they are communicating with the same company, one with a distinguishable brand identity.

However, using marketing and transactional messages as two complementary email channels is also about leveraging the power of these triggered messages and their possibilities for upselling and cross-selling. Transactional emails in general have high engagement metrics, as they are sent to customers who are awaiting a confirmation. Including promotional opportunities within these emails, like further offers or services, can be a great way to boost your client conversion rates.

Understand how deliverability affects your email ROI

Creating and sending beautiful email campaigns is pointless if they’re not landing in the inbox. Even though the hard work seems over when you press the SEND button, your emails go through a whole journey to reach your recipient, and many factors involved could determine whether your email lands in the inbox or the junk folder.

Email campaigns for the customer lifecycle in the travel and tourism industry

We’re sure that after spending quite some time learning about the tools and features that can help boost your email sendings, you’re eager to get new ideas and start creating your own campaigns. We have explored how to combine your transactional and marketing efforts to leverage triggered emails’ open rates, and now it’s time to take a look at some of the marketing emails you can implement.

There are multiple stages in planning for a trip and multiple steps in the customer lifecycle in the tourism industry, and you need to be prepared to walk your customers along the way.

Welcome Programs

Welcome series give you the opportunity to greet your customers upon joining your platform and to offer them some valuable information to make the most of your service. Letting your customers know about the kind of communication they can expect from you and allowing them to choose between different options will enable you to send them targeted emails that are more likely to interest them.

AirBNB's welcome email on boards the customer

Airbnb’s welcome email is great at onboarding users and highlighting the next steps to get started. It’s eye-catching and includes clear CTAs to help users navigate the platform.


Who wouldn’t want to celebrate their birthday somewhere magical? Wish your contacts a ‘Happy Birthday’ and include a discount on a weekend getaway or a promo code they can apply on their next booking.

Loyal customers go a long way. Why not use the data you have available to thank them for X years together? You could include an exclusive offer to reward them for their loyalty.

JetBlue Anniversary Email Example

It doesn’t get much better than JetBlue’s anniversary email. This fun, friendly and slightly cheeky approach lets customers know they are valued and encourages them to stay loyal to the brand.

Flash Sales

Limited offers are extremely common in the tourism industry. Even though travellers are now getting savvier and exploring different possibilities before booking their trips, many decisions are still made based on great deals and amazing discounts.

Some business have turned the flash sales model into the core of their business, like Secret Escapes, Voyage Privé or Groupon. Even if this is something you are not interested in doing on a regular basis, offering tickets at discounted rates or cheaper upgrades can help boost your sales during a particularly quiet period.

Secret Escapes Flash Sales Email

Secret Escapes uses flash sales on a regular basis to entice users to book trips. They always feature a very attractive discount, and put an emphasis on how long you have until the offer ends.


If you ask people about their interests, chances are many of them will say travelling. Even if we don’t have the money, fantasizing about different city-breaks and dream vacations is something we’ve all done at some point. That’s why, creating regular content that promotes your top destinations or exciting leisure offers will allow you to entice your contacts ahead of their upcoming week off.

Going on holiday normally means spending a big amount of money, so people are not likely to book a trip every time they receive your newsletter. But if you regularly send them content that adds value and they love reading, they’ll probably think of you once they’re ready to book their trip.

Skyscanner Newsletter

Skyscanner makes people really want to travel by emailing them travel insights, news, guides and articles. Their clear headings and beautiful pictures really manage to trigger that well known wanderlust fever.

Seasonal Events

There are different ways in which seasonal events can be used to increase engagement with your email campaigns. National holidays and vacation periods are always a great excuse to promote and offer exclusive deals on some of your favorite picks. It could be that someone’s not thinking about travelling during the Easter break until they see those amazing pictures in your email.

There are also certain festivities that make places more attractive, like Christmas markets, street festivals, cultural events… Piggybacking on whatever’s taking place in a specific location could be a good way of encouraging people to finally decide on making that trip they’d been thinking about for a while. Even designing creative campaigns around certain marketing moments can have a very positive impact on your conversion.

Vueling Seasonal Email

Vueling tempts subscribers with a night out on Valentine’s Day with a special email campaign that includes great deals on flights, car rental and hotels. The inspiring visuals, great copy and enticing offer make this a great example of email marketing for special dates.

Information Emails

Building a good reputation online is hard work and it takes time, but losing your customers’ trust is something that can happen really easily. If your users have chosen you to book their flights, trains, accommodation or tours, only to find that your website has changed or it’s down, or there’s a strike that will impact their departure times and you haven’t warned them, they’re not going to be happy. People get stressed ahead of their vacations, so anticipating any potential issues and giving customers alternatives goes a long way.

Southern Railways Information Email

Southern ensures their customers are ready to use their new platform when they decide to book their next trip by carefully explaining their changes. The “text only” email ensures the message is not mistaken for a promotional campaign, and the handwritten signature at the bottom gives it a more personable feel.

Nurturing Emails

How many times have you browsed around for flights or accommodation, just to check out the prices? Even if your customers are not ready to book their trip at that time, chances are they won’t forget about it completely. Remind them about their search and tempt them with some nice pictures to ensure they come back to you once they’re ready to complete their booking. You can even add some valuable content, like a city guide or top leisure choices at their destination, to help them make up their minds.

Alternatively, you can send them some similar suggestions based on their previous searches or booking history. If a user has been browsing around for winter sun destinations, why not nurture them with other places they might not have thought about?

Expedia Nurturing Email

Expedia nurtures clients looking for flights to Paris with this fantastic email that includes a powerful combination of images, valuable content and strong CTAs.

Abandoned Booking

We’ve all been there. Sometimes you’re just about to complete your booking, but something gets in the way. Maybe it’s the challenges of catering for a large group, maybe you didn’t have your bank card with you or maybe you just thought about it twice and decided it was too much money.

Send customers a reminder email with their booking information and a link to return to their account. You can also tempt them with a special discount, just in case they were having second thoughts.

Norwegian Abandoned Cart Email Example

Norwegian’s simple email reminds users about their abandoned booking and encourages them to take action by letting them know the flight is filling up quickly and ticket prices raising. The CTA allows customers to return directly to the booking stage.

Post-Booking/Before Travelling

We’ve all received them and, most probably, we’ve all opened them. While, in other industries, purchasing is in fact the end action, booking a trip is by no means the end of your relationship with a customer. Actually, the time span between the booking and the actual trip might last months, so it’s important to keep in contact with reminder emails that provide useful information and additional services the customer might be interested in.

The number of emails you send can vary, but you’ll always want to send one a week or two before their journey, providing them with their booking details again and including upselling and cross-selling offers (upgrades, transfers, tickets to attractions, etc…).

SouthWest Reminder Email Example

Southwest’s reminder email provides users with the necessary information prior to departure, while clearly informing them about the steps they still need to complete. They also use this opportunity to promote alternative products and services.

Price/Availability Alerts

We all know how much prices and availability change in the tourism industry. Some of your customers might even spend quite some time searching for the cheapest option and many are in the constant lookout for the perfect time to book in order to get the best deal. Why not send contacts an alert informing them about changes on the price or availability in their desired flight, train or accommodation? Or if something they had browsed before it becomes unavailable, why not suggest them some alternatives?

These fluctuations are likely to give your contacts a sense of urgency to book. However, too many emails might become too spammy and lose all of their effect. The best option is to allow your users to predefine the kind of alerts they want to receive, to ensure the emails you send are actually the emails they want to read.

Skyscanner Price Alert Email

Skyscannner’s Price Alerts are simple and straight-forward, but still manage to include links to some of their other offers and services. Since Price Alerts are regular and subscribers could find slightly annoying at some point, they make their unsubscribe and email management links very obvious throughout the email.

Thank You Email

Once a user has completed their trip, make sure you thank them for their visit. This is a great opportunity to ask for their feedback and encourage them to share their experience online, by directing them to your social media channels. You can also ask customers to share their pictures or user generated content with you – it will be the best kind of promotion.

Folks Thank You Email Example

Volks Hotel’s email uses their Thank You email as an opportunity to ask customers for feedback and reviews. They also reward them with a discount code for future bookings.

Feedback Emails

Marketplaces rely on users’ opinions to rate the different activities and accommodations, although not everyone remembers to go back and share an opinion. Even if you are a hotel or travel company and have previously emailed your customer to thank them, they might have completely ignored your feedback link. Make it easy for them by including a quick survey in your email, so they can rate their experience in just a few clicks.

Booking Feedback Email

Booking.com knows that travellers around the world read opinions about their hotels before booking. That’s why they make it really easy for customers to rate the place they’ve stayed at.

VIP/Loyalty Programs

It is not uncommon for airlines and even hotels to have loyalty or frequent traveller programs to engage customers to return to them. Emailing members to let them know about their points, offering them promotions to increase their balance or rewarding them for reaching a certain milestone is a great way of keeping them engaged and ensuring they remember your company.

Alternatively, you can have different tiers for returning customers that always book their holidays through you, providing them with special discounts as they reach their fifth, tenth, fifteenth booking.

AirAsia Loyalty Email

Air Asia encourages frequent travellers to redeem their points and gain extra ones with special deals and offers to make them feel special and increase their loyalty to the company.

Re-engagement Programs

For some businesses in the tourism industry, their relationship with their customers might be a one-off. Other companies, though, rely on building a lasting relationship with their users.

If a customer’s been absent from your brand, entice them back with a reactivation campaign. You can remind them about what you offer, tempt them with travel ideas and even add an incentive that could convince them to return to you, instead of booking with one of your competitors. If nothing else works, you can send your inactive contacts a ‘We’ve missed you’ campaign, asking them whether they want to stay engaged or end the relationship. Remember, constantly emailing people that don’t want to receive your messages will impact your deliverability.

Re-engagement Email Example TripAdvisor

TripAdvisor relies on users providing feedback on the different places they visit. This re-engagement email targets subscribers who had researched specific locations but never returned to share their opinions.

Summing Up

When used wisely, email is a really powerful channel that will not only help you build and maintain a lasting relationship with your customers, but also increase your ROI. Finding the right balance between mass communication and one-to-one personalization is key to make the most out of your email sendings.

However, what works for one business might not work as well for another one, so finding the right email marketing strategy for your company will require testing different options. Get creative, give some of these ideas a go and compare the results to find those that will give your company the biggest uplift.

Marketers Opting for Homebuilt Tech Despite Strain on Team

Marketers reported that, on average, they lose 13.8 hours per week on their homemade technology.

  • 51% reported that working with a third-party provider was less time consuming
  • Data security was reported as the main concern with a homebuilt marketing solution
  • 54% reported the cost of switching to a third-party was the main barrier

New research at Mailjet, surveying 600 marketing and IT professionals in the US, UK, and France, found that marketers are opting for homebuilt tech, despite losing a third of the week to usage.

According to the research, 77% of decision-making level marketers in the UK, and 75% in the US, have developed or are currently developing homemade technology in their current role. However, the study has also identified concerns with the cost, time spent, and expertise required to build and maintain these tools.

Cost weighed against productivity

When considering whether to use a homebuilt or a third-party solution, over a quarter of marketers (27% in UK and 30% in the US) said cost was perceived to be the biggest risk to using third-party technology, closely followed by data security (21% in the UK, and 20% in the US) and reliability (10% in the UK and 9% in the US).

Despite this, over half of the respondents using a homebuilt solution reported that they found it to be more time consuming than using third-party technology. So while a homebuilt solution might be seen as cheaper, it could also potentially be the more unproductive solution.

In addition, 39% of respondents said they were still looking for talent that possessed the right skills to manage their internal infrastructure. This is due to the gaps identified in their own team to keep up with new processes, best practices, and tools.

Deciding whether or not to trust your homebuilt solution to manage your marketing capabilities, or procure a third-party provider to reduce the workload on the team, are key considerations. Finding the right technology partner with the necessary expertise and on-going consulting capabilities can often reduce the financial and resource cost of an already stretched team.

The importance of data privacy and security

Data security was quite a divisive subject between the UK and the US.

While 51% of UK marketers reported that data security was a main barrier to outsourcing to a third-party, it was also selected as the second biggest concern with a homebuilt solution, beat only by cost. UK marketers are wary of a third-party’s ability to prevent data issues or breaches, but they are also resistant to placing trust in their own homebuilt technology. Meanwhile, only 34% of US marketers cite data security as a main barrier to outsourcing, but are equally concerned about their own internal security capabilities.

Maintaining an infrastructure that protects businesses’ data properly can be a full-time job. Not to mention keeping up with the ever-evolving laws and practices that have to be monitored and followed diligently. Data privacy and security has to be a top priority for businesses in a post GDPR world, but also the safe storage of confidential customer information.

Choosing the right external provider that can maintain state of the art security and privacy practices will also add an additional level of data protection and reassurance for companies that may not have the right skills and resources to provide the highest standards in-house.

Judy Boniface

Chief Customer & Marketing Officer at Mailjet

Email Infrastructure

In the UK, email marketing is among the most commonly used homebuilt solutions at 73%, surpassed only by advertising tools at 77% and project management tools at 76%. With the prevalence of homebuilt email marketing, it is important to assess its performance routinely and potentially consider alternate options. Notably, internal transactional email solutions is close behind at 71%.

In contrast, it is far more common to outsource email infrastructure in the US, with only 65% of respondents using their own internal email marketing services, and even less (58%) using an internal transactional email solution.

There are a couple key considerations that may indicate that it’s time to switch from a homebuilt solution to a third-party infrastructure. These considerations could also help validate that your homebuilt solution is capable of handling your email needs. So let’s take a quick look at some of these considerations:

    • Deliverability: Arguably, the most important feature of your email infrastructure is its ability to land your emails in the inbox. Maintaining deliverability through the collection and analysis of statistics, as well as building and correctly setting up an internal infrastructure can be difficult.
    • Cost: Building and maintaining an infrastructure capable of handling your sending can be costly, but it does have to be weighed against the cost of outsourcing.
    • Data Privacy & Security: A large concern for all companies, keeping your data under your own roof may be the safest choice for you. On the other hand, ESPs may have certifications that better fortify them to protect your data, as well as free up space for you by providing all the storage you need to private information stored.
    • Scalability: As your business grows, it’s important to consider if your homebuilt infrastructure will be able to grow with it and what the costs involved will be, both monetarily and for growing your workforce.
    • Maintenance & Support:Email infrastructure needs constant care because if there is an issue in your sending, it can interrupt the entire marketing machine. You’ll have to make sure you have the right team in place, whether it’s one you built in-house, or the support team offered by your ESP.
    • Stats & Analytics: The bread and butter of your emailing, making sure you have a robust stats & analytics system in place can make all the difference in your sending. Both the collection and storage of statistics can take up a lot of room, but they’re necessary to track and improve your sending.
    • Template Builder: Templates may seem like a small thing, but they begin to take up more and more of your developer resources as your business grows. Additionally, ensuring that all templates are responsive is necessary to maintain engagement.

The Email Infrastructure Handbook: Homebuilt vs Outsourced

Topics like cost, data & security, and scalability are just a few of the considerations that have to be taken into account when making your choice.

To help you out, Mailjet has put together a handbook that digs deeper into every consideration you’ll have to take into account. Once you know what you’re up against, we then lay out your three options: homebuilt, outsourced, or a hybrid of the two.

Guide to Creating Responsive Emails

In the past, when you received a non-responsive email, you blamed the phone, you gave it a shake, or you might even have tried the classic but miraculous technique of closing and reopening the app. That was then, when our inboxes still seemed like remote digital paradises.

Now, how many emails do you get a day? 20, 30, 100? I wouldn’t know where to start counting them. For a while now, when I get an email that looks odd, with cut-off images and blocks aligned so strangely that the whole thing looks like a Picasso, I’ve deleted it without further ado. And I’m not the only one: 80% of people would delete an email that doesn’t display properly on their mobile device.

For this reason, in a world where mobile is king and people like me don’t appreciate all the effort that goes into your newsletters and campaigns, deleting them without the slightest hint of remorse, responsive email design is crucial.

What is responsive email design and why is it so important?

Responsive email design is not a new online phenomenon, but if you aren’t a designer or don’t work in digital marketing, you might not be quite sure what it is.

A responsive – also called adaptive – design is a design that adapts and displays properly on screens of various sizes. For example, avoiding an image being wider than the screen or the user having to increase or reduce the size of text to be able to read it.

Although here we’ll be talking about email design, this technique can also (and especially) be used for web page design and layout. Why is it so important for design, both of emails and web pages, to adapt to various devices? Well, this is almost a rhetorical question, but we wanted to add a touch of suspense.

An article on Email Monday claims 59% of emails sent today are opened on mobile devices, and only 15% are opened on a desktop. And the same is true of web search: almost 60% of Internet searches are done on mobiles. Both of these are more than good enough reasons for brands to want to make the user experience as easy and intuitive as possible.

So what precise factors determine how an email displays?

Device screen size

First and foremost, the main factor that affects how a user views an email is undoubtedly the device type. Email is accessed differently on a desktop computer, Samsung Mini, and a digital watch.

On a desktop, the screen is much larger and we have a mouse to help us navigate, scroll, and click easily on text links or buttons, however small they are.

On a phone, the story is somewhat different. Here the proportions of the content are reduced to fit on the micro screen of a latest generation mobile (although truth be told some phones are more like tablets). So, images are smaller, the text more compressed, and you need to scroll much more to reach the end.

Email Clients

The other big enemies of responsive email are email clients themselves. If you’re unfamiliar with this term, an email client is a program that allows you to send and receive emails, and manage an email account effectively. The best-known email clients are Gmail and Outlook, but there are many more and each one displays email in its own way.

Email clients have an impact on responsive emails

So what can we do, then? Don’t panic. As the image shows, the top five email clients pretty much have a monopoly, so you can start by adapting your emails based on this data.

These top five email clients have a market share of over 70% between them, so we should prioritize adapting our emails for mobile to be read in these clients.

Different types of email optimization

When we talk about optimizing email design, we have a number of options of varying simplicity and effectiveness. These are the main options:

Scalable email design

Scalable design is the most basic method of adapting your emails. The content of an email of this kind will simply be scaled up or down to adapt to the user’s screen size, but without changing the structure of the email or the layout of the content.

These types of email are the easiest to develop, but in truth scalable design does not deliver the best results.

Fluid email design

Fluid design uses percentage-based sizing to make blocks of content adapt automatically to the screen size of the device. In other words, the content “flows” from the desktop version into the various screen widths, filling the space as the screen width varies.

This format typically works best for text-heavy emails, but it is also very hard to get the layout right.

Responsive email design

Of the three types, responsive design delivers the best viewing experience on all screen sizes. What sets it apart is that it ensures each device displays a different version of the message, optimized for the specific screen size.

Laying out emails like this is quite a complex task, but the good news is that Passport, Mailjet’s drag and drop email editor, allows you to create responsive newsletters by default. We’ll come back to Passport at the end of the post.

How to design a responsive newsletter: best practice

If you use an email editor like ours, you don’t have to worry about media queries, CSS and equally unfamiliar concepts: the editor does everything for you. However, there are other things that might interfere with the end result, and here we’ll tell you what they are and how to avoid them.

Layout of a responsive email template

One of the most common email design errors is using a layout with multiple columns. It might happen because we get carried away by creative urges (or emotion), but this first decision could result in an epic email adaptability fail.

This is because the vast majority of mobile devices have a vertical screen design, forcing them to shrink anything with a wider format, including emails with several columns.

So what’s the solution? Opt for a single-column design; this will ensure that web browsers and email clients display the content of your email in the right proportions, and you won’t have to re-adapt the design to smaller screen sizes. When it comes to mobile devices, simplicity is your friend!

Take a look at some of the faults we’ve taken directly from our inboxes.

Email bugs from non-responsive emails

Images for responsive emails

Images (and gifs) are a fantastic way of making emails more dynamic and attractive. But in responsive email design, images can be a double-edged sword.

Choose an appropriate image size

When it comes to images in email, the (not so big) secret is not to use exaggeratedly outsized or undersized images. If you use overly big images, you run the risk that emails will not display properly or will take a long time to load. And, believe us, nobody is going to wait more than three seconds before moving on to the next email.

On the other hand, using overly small images will not deliver better results either. In fact, what we will probably get are distorted or pixelated images.

To make sure your images display properly and adapt to any device, use images that can adjust to the size of your newsletter: you can cut them down to the exact size before uploading them to your email template or, better still, use an email editor like Mailjet’s so you can edit them directly in your template.

Alt text: a must-have

Despite all the effort we put into selecting appropriately sized images, it might be that from time to time they still do not display correctly. The fault may lie with email clients, which manage the visual content of emails differently, or users themselves who, for various reasons, prefer to block images by default.

But don’t despair! A simple and effective solution is to add Alt Text (alternative text) to accompany the image and display when the image does not. This text is particularly important for two reasons. Firstly, it tells users they are not seeing the missing images relating to the text. Secondly, emails that contain this tag have a better reputation with email clients, because spammers generally don’t bother adding it.

Add alt text to emails to set yourself apart from spammers

Avoid image-only emails

Talking of spammers, another ill-advised technique is to create emails that only contain images, and we’re sure you can guess why. It’s a very risky choice, partly because these messages often end up in the spam folder, but also because, as we just said, if for any reason the images don’t display correctly we have no way of reaching our contact.

Remember: For your email to be effective, aim for a text to image ratio of 60:40.

A good balance between text and image to make it responsive

Calls to action for responsive emails

A basic element of any email design is the call to action (CTA), designed to orientate readers and encourage them to perform a specific action.

If we don’t include clear instructions for our recipients, they might be unsure what to do with our email and move on in a nanosecond. This is also why CTAs and links should be easy to identify and point in exactly the right direction.

When you design a CTA for a responsive email, make sure the buttons are clearly visible by using, for example, a color that contrasts with the palette you’re using, and big enough so everyone can pick them out easily. As we all know, some people are prone to “fat finger errors”!

And of course, no links in the text or image format: these types of CTA can be much harder to select and, in the case of images, even see. Lastly, be careful where you put your buttons and avoid putting them too close together, as in the example below.

Don't put buttons too close together because they are hard to select with fingers

Text and legibility

The text is one of the aspects we should adapt to make sure people who open our messages on these devices don’t feel overwhelmed by tiny fonts and interminable paragraphs.

Hierarchy and priorities

In a web browser, there are a number of techniques you can use to grab a reader’s attention: use colors, arresting images, elegant fonts etc. But on devices with small screens, like smartphones, this is the role of the hierarchy. The hierarchy must be clear to ensure readers grasp the essence of our message, even if they don’t reach the bottom of the page.

People receive a huge number of emails every day, so the competition is huge and it’s increasingly hard to get people to read them. That’s why we should always design our emails with the order of importance in mind, putting the most relevant items first.

Text type and size

As for the text itself, make sure your emails are legible. Don’t aim too high with your use of fonts: opt for a standard font available on any device, like the classic and timeless Arial, Georgia, Times New Roman or Verdana.

Likewise, in this instance size does matter, so be kind to your readers and use a typeface large enough that they don’t need glasses to give your latest newsletter a once over.

Lastly, don’t forget to leave white spaces between one block of content and the next: you’ll make the email look clearer and more modern, without exhausting your subscribers.

Keep text size in mind when making responsive emails

Examples of perfect responsive emails (infographic)

So far we’ve discussed the dos and don’ts of responsive email. After so many bad examples (it’s not our fault our inbox is full of them), we want to show you an example of an especially good email while reviewing all the key things to bear in mind when you design your own.

Courrier International is a French weekly newspaper that analyzes the news in the international press. It offers subscribers a daily newsletter with the most important news of the day from all around the world.

It may be that at first you don’t notice any major differences between the two emails (the desktop and mobile versions), so we’ll take a look at them and dissect what makes it a good responsive email.

Before you press send

You’re good to go and we’re sure that, if you’ve followed our advice, you have in front of you a perfectly responsive email that’s ready to send. But, before you launch your campaign, it’s always a good idea to make some final checks. Here are three ways of checking how your email design displays.

Preview your email

Use the preview panel in your editor to view how your mail shapes up on different devices. For example, in Mailjet you can view the mobile and desktop versions of your completed email and get a clear idea of how it will appear in your subscribers’ inboxes.

Preview your email to see if it is responsive before sending

Send a test email

Another everyday way of checking is to send yourself a test email. You can send it to your own address, to a colleague or a friend with access to various devices, browsers and operating systems to make sure nothing untoward happens to your email along the way. At the end of the day, having an extra pair of eyes to check the content and links and test out the UX is no bad thing.

Extra tip: Go into the reports on previous campaigns and filter them to view the breakdown of devices and the use of email clients by recipient, and you’ll be able to check which ones your customers use most.

Use specific tools

Lastly, for the most meticulous among you we recommend supplementing steps A and B with platforms such as Litmus and Email on Acid. These two tools send your email to more than 50 email clients and give you analysis and previews, saving you time and offering you peace of mind.

How to create responsive email with Mailjet

If you have no coding knowledge (or don’t fancy wrestling with HTML code), you can use our email editor Passport to create professional newsletters that adapt to any device and email client. You just need to drag and drop the blocks of content you want to include in your email, such as images, headings, texts, buttons and social media icons.

Responsive email templates

Another option, for those days when you’re lacking inspiration, is to choose one of the ready-to-edit templates from our “template gallery”, all of which are of course responsive. You just need to select one and edit it to include your content, et voilà!

Over to you

We hope we’ve put to rest all your doubts about responsive email and design; we know it’s not a simple topic. However, if you follow the advice and best practice in this post (and you use our templates 😉), your valuable newsletters will look their best.
Before you get to work, here is a summary of what we’ve covered:

  1. Use a single-column email design for optimum results.
  2. Optimize image size so they adapt easily.
  3. Work on the call to action buttons so they are visible and clickable (yes, for people with fat fingers, too).
  4. Use a typeface available on any device, and pay particular attention to text size.
  5. Make your checks before sending, either by previewing your email, sending a test email or using specific tools (or all three).
  6. Put your trust in an email provider that guarantees you responsive design by default (ahem, we’re the best for a reason).

Sender Score and Email Reputation: What Are They and How to Improve Them

Sender Score and email reputation are two terms very important and relevant to email marketers and deliverability experts.

But to novices and the general public, there is still a lot of confusion surrounding the terms.

So in this article, we will demystify what email sending reputation and Sender Score actually mean and what they each measure.

What is email sending reputation?

Email sending reputation is a complex metric comprised of different reputations to determine email delivery practices. The most important reputations are:

  • IP Reputation
  • Content Reputation
  • Domain Reputation

In 1996, as emailing became mainstream, spam began to turn into a serious issue. To counter this, large internet service providers (ISPs) providing email services began to use IP Reputation to analyze email quality.

IP Reputation indicates how much users want to get email from this IP address by measuring bounces, spam or unwanted bulk mail (UBE). Back then, there weren’t very robust ways to authenticate a domain address, so ISPs had to create complex IP reputation models that differed from each other, but had the similar task of identifying problematic IP addresses.

After a while, IP reputation alone proved inefficient, because it didn’t consider how different IPs could deliver (junk) emails with identical content.

Advances in technology in the 2000s enabled ISPs to develop a new method of measuring the quality of a sender’s emails through content reputation.

Content reputation works on a set of criteria that determine the sender’s quality of their email campaign content. While certain types of content are clear triggers for ISPs’ content filters (e.g. attaching a virus, a string of words asking for bank details, and so on), a sender’s content reputation goes down when their emails keep getting low open rates, flagged, blocked, and unsubscribed.

So IP and content reputation work hand in hand to create an overall picture of a sender’s email practices. IP reputation determines the quality of a sender’s email sending through their emailing history. Content reputation analyzes the type of content a sender’s email has and determines if the sender is trustworthy or not.

But of course as spammers and hackers became even more sophisticated in cheating ISP filters and sending malicious emails, this led to the development of more robust email authentication systems – namely the Sender Policy Framework (SPF) and DomainKeys Identified Email (DKIM) system.

The Sending Policy Framework (SPF) was implemented as a standard in 2014 to check if an email campaign has been sent from an authorized server.

SPF is like an RSVP list of authenticated, valid IP addresses that can send emails on behalf of that domain.

SPF prevents spammers from falsifying the ‘from email address to send spoofing emails’. But the SPF record, by itself, is not enough and can be susceptible to human error and snowshoe spamming (i.e spam propagated across different IPs and domains to weaken reputation and pass through ISP filters).

If a sender indicates the wrong IP domains, then the wrong ones will be able to send emails on behalf of your domain. ISPs have no way of realizing otherwise, and they penalize the sender’s domain for spam.

Therefore, SPF has to go with a DomainKeys Identified Mail system (DKIM), which allows recipients to confirm that the mail comes from the authenticated owner of that domain.

The email itself contains a signature in the header called a DKIM signature or a hash value that allows this authentication. A DKIM signature means that the email has not been tampered or hijacked upon delivery and comes from a valid sender.

As these authentication systems became more robust, ISPs have developed domain reputation, which measures the quality of a domain’s authenticated emails.

Domain and IPs can be different, after all. For example, Mailjet customers could be using shared IPs that we provide and send emails through their domains.

Email sending reputation is a complex metric of other different reputations to determine email delivery practices developed essentially through a constant game of chase and catch between hackers who send malicious spam and the ISPs that are constantly creating new ways to catch them in the act.

Great email sending practices do not end in the way you create the content and design of your emails, but also following strict security protocols that help ISPs identify you as a trustworthy sender.

What is Sender Score?

Using a range that starts at 0 and ends at 100, Return Path’s Sender Score is compiled from non-personal data of over 60 million inboxes from different ISPs, spam filtering, and security companies to create a picture of a sender’s email sending practices.

Sender Scores are normally calculated on a rolling 30-day average.

Sender Score may be also indicative of a sender’s email reputation, but they are not the same. If a sender has a high Sender Score, this could indicate that most of the sender’s transactional and marketing emails land in the inbox.

If a sender has a really low score, then there is a high chance that their email campaigns often have high bounce rates, high block rates and low open rates.

It is important to realize that the Sender Score is ultimately on data that Return Path receives. This score is relevant for ISPs that pay attention to it.

Ultimately, ISPs decide whether you send good emails or not through their own datasets, not on Return Path’s Sender Score.

So while this score might be a good indication of email sending practices, fixing it from low to high does not automatically guarantee that all email campaigns will land in the inbox.

The best way to fix email sending is to look at the source and focus on deliverability (the rate at which a sender’s email campaigns land into the inbox, as opposed to the spam folder), because this is what the Sender Score ultimately attempts to quantify.



How to check your Sender Score

Checking Return Path’s Sender Score is quite easy. Follow these steps:

  1. Go to https://www.senderscore.org/
  2. Register and create an account using your professional email.
  3. You should receive this confirmation email. Click on the CTA Activate Your Account.
    Activate your Sender Score
    Activate your Sender Score
  4. As soon as you log in, you should be redirected to this page.
    Know your Sender Score
    Know your Sender Score
  5. Here, you can look at the Sender Score of either an IP address, or a domain (e.g. mailjet.com).
    Mailjet’s Sender Score
    Mailjet’s Sender Score
  6. Searching by domain name leads you to a page listing IPs sending mail from this domain, an indication of their email sending volume, and, finally, their Sender Score.

These scores could indicate whether this domain has been sending good emails or spammy ones in the rolling 30 days prior to your search.

What is a good Sender Score

According to Return Path’s 2018 benchmark on Sender Score, their Sender Score reveals important data on the following:

  1. Complaint rate – the rate at which users complain about your emails as junk.
  2. Unknown user rate – the number of invalid users in your subscription lists
  3. Spam traps triggered – spam traps are email addresses that don’t belong to anyone and have the primary task of catching spammers and senders with poor list hygiene practices.

Pristine spam traps are email accounts never owned by anyone and have been created to catch bad senders. Recycled spam traps are abandoned email accounts that have now been recycled into spam traps.

As such, domains with Sender Scores of 90 and above have below a 1% complaint rate, ~1% unknown user rate and an average of 0.36% spam trap hits.

Conversely, those with very poor Sender Scores of 10 or below had a 7.4% complaint rate, 7% unknown user rate and an average of 7.53% spam trap hits.

Having a good Sender Score and having emails sent to the inbox is good for the business, but it’s not the end-all to great email sending. More on this on the next section.


When Sender Score won’t save you

A high Sender Score does not mean an end to your email worries.

Like any other aggregate, Sender Score misses out on other very important factors that influence overall email sending.

After all, this proprietary system comes from Return Path and not from ISPs. Hence, ISPs may have slightly different ways of measuring your email reputation and include other variables that determine whether this campaign should be sent or not.

Return Path suggests:

A high Sender Score on its own doesn’t translate to higher inbox placement rates. Subscriber engagement, a mailbox provider’s own reputation calculations, and the content in the incoming message—none of which are included in Sender Score calculations—all factor into each mailbox provider’s final filtering determinations.

Email deliverability experts agree on this, including Word to the Wise founder Laura Atkins:

Basically, just because you have a great SenderScore doesn’t mean you’re going to have good delivery. Likewise, having a poor SenderScore doesn’t mean your mail is destined to be undelivered.

Sender Score is not the end-all be-all to determining if your email campaigns are great in all areas.

Ultimately, the Sender Score does not measure content creativity, which is crucial to creating email campaigns with high open rates.

Therefore, it is best to focus on your deliverability, as this is the best indicator of whether your emails get delivered to the inbox and not spam folder, or altogether remain undelivered.

It is also a good idea to invest in other email reputation indicators that might be better suited to your email sending.

An email marketer in his Medium article, for example, lamented on areas ignored by the Sender Score. Some 90+ scores scored low on Google Postmasters, which analyzes and measures email sending practices loosely based on Gmail’s complex filtration system. Therefore, Google Postmaster Tools may be a great alternative for you if most emails in your lists are Gmail users, but less so if they are from other ISPs.

In fact, it’s best to understand that ISPs might not only measure email reputation differently, but they might also have different acceptable standards for various metrics altogether.

This is the main reason why, for example, an email campaign might get great deliverability results for Gmail, with most emails landing into their inboxes, but less stellar results in Outlook.

In any case, ISPs have different filtration systems and they modify them often in order to get a step above malicious spammers. If every ISP filter worked the same, then each one would be easy to hack.

So, really, the best way to improve your email sending is to simply improve your email sending practices. Sometimes, the best changes are the most obvious ones.

How to improve your Sender Score and email reputation

As discussed, sender reputation comprises of other reputations based on your email sending:

  1. IP reputation that is tallied by how much people want to see emails from this IP address.
  2. Content reputation that measures how good or spammy your email content consistently is.
  3. Domain reputation that checks the email sending from your domain as a whole, validated through authentication methods.

It becomes a matter of ensuring that your sending practices are great across the board. So here we will compile a guide to ensure that you are sending emails in the best possible way.

Authenticate your SPF and DKIM

Authenticating your account ensures that only a specific list of IPs can send emails using your domain.

This keeps spammers from falsely delivering emails through your domain.

Think of DKIM as the signature you include in every email campaign. The DKIM is a powerful proof that the recipient’s ISP can use to check if these emails they have received are domain-authenticated and valid.

If the signature matches, then the email goes into the inbox – other things equal.

If it does not match, then it’ll go into the spam folder (or gets a hard bounce).

DKIM Process
DKIM Process

SPF meanwhile is a list of the authenticated IP addresses within that domain.

DKIM and SPF work together to ensure that you do not become the victim of a spoofing attack (i.e. where a sender masquerades as another domain to send spam).

Create sub accounts for your different email needs

Separating your marketing and your transactional emails by creating sub-accounts is good for organizing different types of email sending.

By separating these two types of emails, marketers can better keep track of various metrics, such as:

  1. Scheduled sending of marketing emails.
  2. How often users trigger transactional emails
  3. Different types of transactional emails getting triggered
  4. Different types of marketing emails being sent

Separating both also ensures that deliverability rate issues on marketing emails do not get passed on towards transactional emails and vice-versa.

Imagine if ticket people got their transactional ticket confirmation emails into the spam folder, because an ISPs filtering system identified the sender as a spammer through their marketing emails. This could get email marketers and their companies in a whole lot of trouble.

Take charge of your engagement data.

Email engagement is comprised of data on how engaged your users are with your email campaigns. These include:

  1. Open rates – the rate of users opening email campaigns.
  2. Click rates – the rate of users clicking on links and CTAs within these campaigns.
  3. Complaint rates – the rate of users complaining about receiving specific email campaigns.
  4. Engagement time – the amount of time they spend on reading specific email campaigns.
  5. Unsubscribe rate – the rate at which users unsubscribe after receiving your email campaigns.

The image above shows some of these metrics in action on Mailjet’s dashboard.

Of course, these stats can take a long time and creative effort to improve.

Sending emails with great engagement rates can’t be done overnight. After all, brand loyalty can only be fully nurtured above and beyond email marketing.

But senders can already tweak some things, such as making emails more responsive, and getting some email content and design inspirations online.

Users prefer to engage with beautifully-designed emails as opposed to suspicious plain text ones.

Other than design, of course, the frequency and time of email campaigns also matter.

ISPs consider engagement rate very highly in their content filtering algorithms.

Segment, A/B and Personalize

Segmentation involves dividing your email contact lists based on a set of criteria. Each segment can be, for example, based on region, gender, or interests, among others.

A/B Testing is when marketers send multiple versions of the same campaign and analyze which one(s) perform the best.

These techniques can allow marketers to create more specific and personalized email campaigns that users will want to open.

Of course, A/B testing, segmentation and personalization are all related to improving on email engagement rate.

Above are some A/B testing stats on our dashboard. Version A has

  1. The best Open Rate and Click Rate
  2. The highest Click Rate
  3. The lowest unsubscribed rate
  4. The least amount of Soft and Hard Bounces

These indicate that Version A is the winning version and is an email that people want to open and engage with. You can use this information for future campaigns, or if you had only tested with a small sample size, you can automatically send this email to the remainder of your list.

Create a checklist for your email campaigns.

A best practices checklist for all your email campaigns is like an accountability log to the senders themselves right before they send their email campaigns. A checklist allows them to make sure that they have not forgotten about anything before sending their email campaigns.

With tactics in improving engagement rate and having enabled authentication systems to securely send email campaigns, the last thing marketers can do before they send their email campaigns is to run them through a checklist that should include

  1. Whether they have written a good subject line.
  2. Included a pre-header.
  3. Checked all links are accurate and include UTM tags if necessary.
  4. Proofread.
  5. Good CTAs
  6. Proofread.
  7. Proofread once more (remember, there’s no undo button)

Now, this checklist can be automated, with a tool that runs through emails campaigns to ensure that they are ready for delivery. But this checklist does not have to be automated. Senders can also check through manually. Things that you can check include:

Clean email lists and have double opt-in

Regularly cleaning your contact lists prevents marketers from sending emails to inactive users, some of which might have been converted into spam traps. Clean lists also have more engaged users, especially when they are well-segmented.

One of our customers, Product Hunt has a great way of cleaning their subscription lists. For inactive users (i.e have not opened Product Hunt newsletters in a while) they send an email stating that they have been automatically removed from the list.

Create email campaigns that matter

Of course, the most important thing that you can do in your email marketing is to create a strategy that includes processes, workflows, tactics, database of email campaigns, and so on. Devising an email marketing strategy means that you have a solid idea of what to do through the course of your marketing projects.

However, an email strategy is not something that’s rigid and bureaucratic. A great email marketing strategy – like any other marketing strategy – allows marketers to experiment throughout the project, in order to adapt to new trends and key moments that suddenly open unexpectedly.

Return Path’s Sender Score and Email Reputation are ways to measure a sender’s email sending practices.

But Sender Score does not directly measure a sender’s email reputation. ISPs have their own proprietary algorithms for the way they measure email reputation.

Ultimately, the path to getting into the inbox is on improving deliverability, and we have highlighted ways to do this.
