Inbox Preview: Send Perfectly Displayed Emails for Better Results

Before hitting the “send” button, you usually check two things, many (many) times:

  • You verify if you selected the right contact list and segments.
  • You make sure your email looks good on all devices.

But devices are not the only thing to think about. The problem with email is that every inbox – Apple Mail, Outlook, Yahoo!, Gmail and all of the others – render the same email very differently. While we’re doing our best to offer the best result on all email clients, we have no control over the rules defined by those clients. For example, even Gmail will not render Google fonts and there’s nothing anyone can do about it (except Gmail, of course)!

Because of this, it’s very important to test your email across all of the email clients your audience is using to make sure they’re seeing your message the way you expect them to. To help you do this, we have just launched a new feature that will help you preview your email exactly as is it will be displayed when read by your contacts.

Why is this important?

Before sending a marketing campaign, or validating a transactional or automation template, you need to send yourself and your colleagues some tests to check if your email is flawless.
If you are not currently doing this, you are probably missing errors and design flaws that can be critical.

If you want to make things right, you’ll want to send a test to countless different inboxes to be sure it’s displayed correctly. It’s a very important step, but it can also be time-consuming.

Perhaps, play it safe, you check your statistics and decide to focus on the most used inboxes among your audience, create an account on each and send a manual test to each of these inboxes. This is a smart strategy, but tedious execution.

Today with Inbox Preview, avoid manual testing and save time by previewing the email you want, on the email client and device you want. A perfectly displayed email can mean much better engagement. And, with Mailjet’s new email preview feature, it’s just a few clicks away.

How to perform your tests

This feature is available for our Enterprise clients to monitor every detail of their emails before sending. If you are already a Mailjet customer, you can get in touch with your Customer Success Manager. If not, contact our Sales team and they will help set up a custom enterprise account.

Once you are all set up and your email is ready in your email editor, click on “Preview email”:

Preview Email

When this screen appears, press “Start testing”:

Start Testing

Select, test, send perfect emails

You are now able to select the email clients/inboxes you want to preview your email in. Once you select them, click on “Run test” and let it happen! In this example, we have selected the most popular email clients.

Run Test

If your email looks good on all the selected items, you are ready to send!


This is something you should perform before any email is sent as email clients have updates and a template that works fine today perhaps won’t be looking as good tomorrow.

Find your saved previews

Your email previews are saved in the gallery. You can check them later by clicking the “Preview” button.

Previews Available

Hover to preview:

All available preview inboxes so far

Right now, you are able to preview inboxes across multiple brands, versions, devices, and countries. You can select only the ones relevant to you and your audience.

Tokens to use the way you want

Each preview you select costs 1 token. You can buy more tokens by simply asking your Customer Success Manager.
Note that you have the flexibility to use them the way you want. Let’s say you buy 1000 tokens.

  • If you have one account, you allocate all this amount to your one and only account.
  • If you own many sub-accounts (which is very common for Agencies, franchises, and different teams in the same company) you can distribute your 1000 tokens and provide a specific amount to each sub-account.

Let us know how this works for you or if you have any comments about this feature 😊

Dynamic Content for Marketing Campaigns to Level-up Your Email Personalization

How cool is it to receive an email that you feel is tailored just for you? It’s really important to help businesses stand out. In fact, 65% of email marketers deem dynamic content as the most effective personalisation tactic in their arsenal (One Spot). Also, companies who are personalising experiences are seeing, on average, a 19% uplift in sales (Monetate).

Segment’s research found that 44% of consumers say that they will likely become repeat buyers after a personalised shopping experience with a particular company.

Mailjet already allows you to personalize your emails by adding contact properties such as the first name or the company of your recipient in the email content.

Now, you can go even further into personalization by dynamically displaying content based on the segments your contacts belong to. No need to create a campaign per segment anymore!


How to Create Dynamic Sections?

When you’re in Mailjet’s email builder and you hover on each section of your template, you now have the option to easily personalize your campaigns.

Click on “add condition” to be able to choose the segment of contacts you want to display your content to:

By default, each section will be displayed to all recipients.

In order to make the most of this feature, make sure your segments are well defined so that you can create as many options and sections as you want.

Preview All the Different Displays of Your Campaign Before Sending

Before sending your email, you’ll want to make sure you selected the right segments for each dynamic section. On the top right of the builder, click on “Preview & Test”. You can select “Display entire email” or “Display by segment” to preview your campaign as recipients will see it, depending on which segment they belong to.

You are just one click away from sending!

Two Examples to Show You What You Can Do With Dynamic Sections

You can personalize content and sections for unlimited segments. Here are some use cases to help you better visualize what you can do with this new feature.

Example 1: You can create a section with a promo code, and decide to display it only to contacts on your loyalty program. Other regular customers won’t see it.

Example 2: You are preparing your weekly newsletter and you have an event coming up in NYC. To spread the word to your audience living in NYC, you can use dynamic sections to promote your event and display the section only to the segment of your contacts living in NYC.

A Premium Feature

This feature is available for our users on Premium plans.

Activity Logs: Track all Changes Made to Your Campaigns in Mailjet

If you are working in a large company or work with a team on your email campaigns, you sometimes might feel like there are too many cooks in the kitchen. Involving many people on the same project is often necessary, but not so easy to manage.

But, don’t worry, we’ve thought of this, and we’re here to help with our new launch of Activity Logs!

What Are Activity Logs?

You no longer need to worry about asking every single person on your team to find out who was responsible for a modification you want to change before sending your email. To save you time and effort, Activity Logs allows you to track all these changes in our app!

Activity logs help you uncover who was involved in every modification done on your templates and campaigns.

Where you can find Activity Logs?

Step 1: simply click on the “Manage” button on the right side of your campaign or template list.

What you can see with Activity Logs

This new feature will help you quickly identify your collaborators changes to the campaigns and templates you are collaboratively creating.
You will be able to view the status of the campaign or template (i.e. Sent, Draft, Published) and metadata about changes made like date, time, and user. Finally, you will be able to view the specific actions taken, such as changes to the title, subject, “from” name and address, any changes to the content, contact list, and the users who scheduled or sent the campaign.

In short – the full details of who, what, when, and how changes were made.
Activity Logs Mailjet

Activity Logs are Now Available

Actions done in your campaigns and templates will be tracked from now on, even on existing campaigns or templates that you have in your Mailjet account. This means that it is enabled on all your campaigns and templates that you already created. Changes made prior to the launch of Activity Logs will not be tracked, but all changes moving forward will

Please note that events done via API are not registered.

Contact Management Under GDPR: The Ultimate Set Of Features You Need

Mailjet has been one of the first ESPs (ok THE first) to get onboard with all GDPR requirements.
We know you missed us talking about GDPR, right? 😂

On a more serious note, our customers were very curious about GDPR compliance and are pretty concerned about security and data protection. You know, we are constantly working to make things easier for you. We gathered below all features related to contacts and GDPR available for all Mailjet’s customers.

Refresh your subscription form to add the new GDPR-compliant consent box

For optimal transparency and safety, we advise our users to implement Mailjet’s double opt-in subscription widget to build their contact lists.
Now, in addition to making sure that you have the consent of your recipients, you’ll be able download the proof of consent from each of your contacts. ✍🏽

Widget Mailjet GDPR

How do we do this?

  1. In widget creation, a small checkbox has been added. Tick the box.
  2. Customize the text of the checkbox.
Widget Mailjet GDPR

When a user subscribes to your newsletter, the consent information, including the widget name and consent checkbox text, will be added to their contact profile.
Here is an example of a GDPR-compliant checkbox:

Widget Mailjet GDPR
  1. You are all set!

Please note that if you already have our subscription widget on your website, you will need to re-install it to activate the GDPR checkbox, which will enable the proofs of consent to be stored.
This also means that you won’t be able to download a proof of consent for your old contacts.

No worries, though! If you’re using our widget from the beginning, we are here to cover you in case you encounter any issue with a recipient claiming she/he never consented to receive you information. We’ll be able to provide this information as it is registered in our system 😉.

Have your consent proofs stored and available for download when needed

Another great news is that you can now access and download this proof of consent directly from your Mailjet account, whenever you need it, without contacting our Support team.
Wondering how to download the consent proof of your contacts?

  1. Search for a contact in your Contact lists.
  2. Click on it and you’ll access all the details related to it (we did some re-design here by the way 🎨).
  3. The proof of consent needed can then be downloaded right from here:
Contact Consent proof

Delete a contact in one click

As you know, under and since GDPR, contacts are more aware about what informations they share, and it’s really common that they ask about being deleted from any list and any communication.
So besides unsubscribing, checking statuses and statistics, editing contact properties, removing a contact from a list, it’s now possible to delete a contact…from all your lists, in just one click, straight from the contact overview page:

Delete contact

Important note: statistics generated for all the emails sent to the removed contact will not be altered because of the deletion of the contact. But the contact and its informations will no longer be seen in the database, or available for future sendings.

We hope we helped you become (even more) GDPR-compliant.
Let us know what do you think once you set up the new widget on your website, and your opinion about these news in general!

GDPR: A Mailjet “How-To” Guide To Prove Your Contacts’ Consent

Mailjet was the first emailing solution to be GDPR-complaint… and the first one to warn you about how the new regulation was going to affect the way you communicate.

While it can sound terrifying to some, if your contacts have given you their explicit consent to receive emails from you, this shouldn’t be keeping you up at night. In fact, it can even be an opportunity to improve your deliverability, by doing a nice spring cleaning on your lists, and asking your active contacts (those that open and click on your emails) if they want to spend the summer (and maybe the rest of their lives… ❤) with you. 😉

We’re pretty sure you’ve already heard about GDPR quite a lot, given its importance and the heavy fines for non-compliance. Don’t panic, though – we’re here to help you, step by step!

Do you have a Mailjet account and want to re-opt in your contacts, in order to have proof of consent? Read on and follow all the steps here to requalify your contact lists!

Requalify your lists and prove your users’ consent

Under GDPR, if the consent you’ve gathered from your contacts doesn’t match the regulation’s requirements, you will have to:

  • Obtain consent again, following all GDPR requirements (you’ll find all you need to know about it on this article).
  • Stop processing the concerned data and delete it.

N.B.: You can use our subscription widget to get consent from all your future contacts. This way, you’ll be sure that your contact details have been reliably collected.

If you need to request consent again, you’ll have to carry out a requalification campaign. In other words, you will need to ask your contacts to confirm they still want to receive your emails by registering this consent again.

Panicking already? Don’t! We’ll tell you how to get this right. 😉



1- Create and send a re-permission campaign.

Create a new campaign and draft your email. You will find several examples of requalification emails in our GDPR SOS Kit.

In your message, ask your contacts if they still want to receive marketing emails from you. Give them two options, YES or NO, to ensure they are aware of what to do if they want and if they don’t want to receive emails from you. That way, none of your contacts will be stuck in limbo: it’s either a YES, or a NO.

-Your YES CTA can be linked to a confirmation page, with a message that could say something like “Thank you for confirming your interest!“.

– Your NO button must be linked to the Mailjet unsubscribe link, [UNSUBLINK_EN].

You can also add a short explanation, such as: “If you do not reply within a week, you will be removed from all communications”. This will further clarify what will happen if your users don’t confirm their interest in your marketing emails and encourage them to act quickly.

To make your task easier, Mailjet has created a requalification email template, which you can either use as is or customize to match your brand’s image. You can download it in MJML or HTML format, and then import it into your Mailjet account.

Just follow these simple steps:

          1. Download the Mailjet template in MJML or HTML.
          2. Open your Mailjet account and create a new campaign.
          3. When choosing the email template, import the HTML or MJML template.


    1. Then, edit the template and send it to your entire contact database as soon as possible.


2- After sending the re-permission email, clean your database.

Let’s start with all the NOs: If you added the Mailjet unsubscribe link on your NO button, the contacts that clicked on it will have been automatically unsubscribed from your list. You won’t have to do anything else.

For those awesome contacts that clicked YES and confirmed that they want to receive emails from you: All you need to do is export the list of clicks one week after sending the email – this will be your new contact list, with all the users that gave your their explicit consent. After some time, you can re-export this list of clicks again, to make sure you’re not leaving any late-clickers behind.

To do so, just follow these steps:

  1. Open Campaign Statistics.
  2. Select the list of people who clicked on the YES button.
  3. Export this list and store it safely.



Do you have to unsubscribe any contacts that didn’t answer?

No, you don’t need to. Since you have the new list of contacts that have given you their explicit consent (those that clicked on the YES button), you can just upload it and start using it to send them your marketing emails. Just make sure you’re no longer using the old list with all the contacts that have not replied.  

Check out Mailjet’s Exclusion List:

If you have multiple email communications under one account and wish to exclude certain contacts from all future communications, you can add them to the Exclusion List so that they no longer receive any marketing communications from you. Note that they will still receive your transactional emails.
Learn more about Exclusion List Management.


What happens if I’m asked to prove consent?

Your proof of consent is the statistics of your requalification campaign. You have the list of contacts that clicked on your confirmation button here, so make sure you store this one safely!



Essential advice for the final run

We have gathered all the information you need and some ideas to help you in our GDPR SOS Kit (including what to do and what not to do in your requalification emails).

New: Edit Your Emails With Others In Real Time

Ta-da! WE’VE DONE IT. What are we talking about? A solution that will make life easier and allow you to collaborate on beautiful emails with ease.

So, what is it? Teamwork in real time!

Now you can work on your email designs with others, at the same time, from anywhere. Finally, the same collaboration tools you expect in all your documents, you can now have in your email campaigns.

Real-time teamwork to create your emails

Are you designing a campaign where you have to write the content? Does your designer have to update the images and ensure that the brand guidelines are adhered to? Working with others on emails often turns out to be complicated and all the extra back-and-forth can waste a lot of time.

Well, here’s something new from Mailjet (and new to email campaigns anywhere): we are developing solutions that will make designing, writing, and sending emails as a team much faster, and easier. You can now work with anyone, anywhere, to build emails at the same time. No more waiting for your colleague to finish editing an email so you can begin to make your changes, join them in our new collaborative editing tool.

How exactly does this work?

It couldn’t be easier

If you open an email campaign or template and someone is already making changes to it, just join the session. The initial of your first name is displayed as soon as you join:

Person joins Real-Time Collaboration session

The best advantage is that you can’t overwrite the changes your colleague is making when you join the template, and vice versa!

You can see, in real time, what your colleague is doing. You can then make your own changes and they will also be visible in real time:

View person 1:

Real-Time Collaboration: a person joins


View person 2:

Real-Time Collaboration: a person modifies

To make teamwork easier, Mailjet blocks the section (text, image, etc.) you are working on so that nobody can make changes while you are working on it:

Real-Time Collaboration session block


Extra secure, for everyone!

This feature is available as part of Mailjet’s Premium and Enterprise subscriptions.
The Teamwork feature is not activated for customers using our Basic plan. However, in Basic and Free accounts, you will be alerted if someone is already working on a campaign or template that you want to edit. You can choose to not edit that email, or else you can retake control.

Popin Real-Time Collaboration block

If you are already on a Premium account, check out this new feature now!
And if you’re not… What are you waiting for? Upgrade to Premium and start collaborating with your team to create awesome emails!

Apply Your Changes To Multiple Email Templates With A Single Click

New year, new feature…makes sense, right?

If you’re always changing things up and switching between different sections and email templates, then you’re going to love this. Mailjet already lets you both save and block sections.

But now you can also link saved sections to email templates, and apply any changes you make in those sections to all linked templates with a single click!
It’s for real! You can decide to have your changes applied everywhere automatically.

Say you use the same header on multiple templates and you want to update – for example – your logo, this new feature will undoubtedly save you a significant amount of time. Pay attention to what comes next ;)

Let’s start at the beginning: creating and saving a section

A section is a part of your email (e.g. the header or footer). You can create, change and save them to reuse them whenever you want in other emails.

Passport Saved Section


There are two ways to create and save a new section:

    • Within an email template or as part of a campaign (either new or existing): you can save a section that you want to reuse by clicking on the “Create a saved section” icon. That section will then be added to your library (“Saved sections” in the left-hand menu), where you will be able to find it later on.
    • Directly in the “Saved sections” menu, by going to “My Templates” and clicking “Saved sections”.

Link and watch it spread!

Now Mailjet has something new for you. Your saved sections can be linked to email templates so that any changes are displayed automatically. Forget the days when you needed to go back over your templates to update them all manually every time you wanted to change something.
Now you get a smoother, quicker, more efficient experience. Sounds great, but how does it work?

How do I link a section to one or more email templates?

Bear in mind that this feature can only be used when you start with a template. So first you need to go to “My templates” to either open an existing template or “Create new”.

You will then have two options:

      • Did you create the section as part of an email template? Save the section. This will automatically link it to that template.
      • Did you create the section in “Saved sections” or as part of a different template? Open the template that you want to use and add the section to it. This will then automatically link it to that template.

Making and applying changes

Do you use the same header for four of your templates? Have you recently changed your logo and want these changes displayed on all four templates?

Passport Saved Sections


All you have to do is edit the relevant section in “Saved sections” and click “Save and Propagate” to apply the changes to the templates in which the section is linked.

Passport Propagate Changes


If this section is linked to all four templates, they will all be updated automatically.
Warning: please check carefully that you want changes to show on all linked templates before applying them everywhere.

A few extra details to help you find your way around

In an email template

You can only link or unlink sections in an email template. Sections created in a template are automatically linked to that template. Sections created in a campaign are not linked to the campaign template.
Warning: if you modify a section in a template, it will be saved, and changes will be applied to all the other email templates linked to that section. If you only want to modify the section for the template in use, you must unlink it from the others.

In “Saved sections”

You can only create and update sections here. If a section is linked, changes will also be applied to any linked templates.

In a campaign

Saved sections can only be linked to templates. They will be converted to regular sections for campaigns.
To link a section that was created as part of a campaign: save it, then look it up in the “Saved sections” library, drag it to a template and link it to that template. Repeat for as many templates as you want.

Unlink linked sections in a flash!

If you want to unlink a section from one or more templates, all you have to do is go into each of your templates and delete the link. If you don’t want subsequent changes to the section to display on that template, then click “unlink”.
Once it has been unlinked, the section becomes just a regular section. If you want to relink it, you either need to save it as a new section (if you have made additional changes) or delete and re-add it from “Saved sections”.

Screenshot: to unlink a linked section


This feature is available as part of Mailjet’s Premium and Enterprise subscriptions.
