From 0-32K in One Year: How Loïc Le Meur Growth Hacks Email

Growing a valuable email list with high ROI is a patient process. But, let’s be honest, most of us aren’t that patient. Part 2 of this 3 part series with Mailjet’s friend and client Loïc Le Meur, successful entrepreneur and founder of and LeWeb, explores how he Growth Hacked his email list to optimize subscriber engagement and gain more followers, fast.

Psst – Did you miss Part 1? Le Meur reveals why he went email-first, how he jump-started an email list from 0 and the content strategy that turned subscribers into big-time fans. Head here for the full story.

Facebook Lead Ads – Le Meur’s Weapon of Choice

In 2016, Mailjet launched an integration with Facebook Lead Ads and Le Meur immediately jumped on it. It’s understandably why. Le Meur had a newsletter signup widget embedded on his website for so that his visitors knew right away that he had a great newsletter that they should signup for.

Loic Le Meur Sign Up

The problem was that it meant his newsletter sign up form was only getting in front of people who already knew his site. What about his social following or those who didn’t yet know Le Meur? This is exactly what Facebook Lead Ads lets you do: gain new subscribers by putting your newsletter subscription right in front of your target audience.

“I love filling out forms” – said no one. Which is why Lead Ads are Facebook Ads that, when tapped on, instantly display a form whose fields are pre-populated using their Facebook profile information. In the case of Le Meur, he created Lead Ads that enticed people to join his newsletter and, in one click, they would be signed up without ever leaving Facebook.

Here’s an example of what the process looks like:

Facebook Lead Ads Example

In terms of Lead Ad Targeting, Le Meur chose two audiences:

  1. People who currently liked the Loïc Le Meur Facebook page
  2. Friends of people who like his Facebook page.

The value of this first target group is often overlooked. People who like the Loïc Le Meur Facebook page do not always visit the page directly. They instead rely on receiving news from Le Meur’s page directly in their Facebook feed. That being said, Facebook’s algorithm does not diffuse every post into the newsfeeds of every Le Meur fan (a main reason why Le Meur moved his strategy to focus on email in the first place). By targeting his existing audience, he got his newsletter subscription form in front of those who already showed interest in what he had to say, but maybe didn’t realize he also had a newsletter.

So what were the results? Shortly after kicking Lead Ads off in 2016, Le Meur gained over 1500 new subscribers for an average of $2 per signup! An excellent cost per acquisition for Le Meur, as it’s this audience whom highly converts when he promotes tickets to attend his event And, thanks to the magic of the Mailjet integration, the new contacts were directly added into the appropriate contact list in Mailjet. No need to export/import.

Making a great first impression – Le Meur’s Welcome Series

Now that Le Meur was investing ad dollars into gaining new subscribers, retention became even more critical. Marketing automation in the form of an email welcome series was the answer to this.

When you enter a store or a restaurant, the way the staff welcomes you can make or break your experience. The digital world is the same. After signing up for a newsletter, the customer will judge the value of the newsletter subscription based on the initial emails they receive. It’s for this reason that an email welcome series can be crucial to subscriber retention, especially considering they tend to have a much higher interaction and click-through rate than a regular newsletter.

Le Meur himself is not a developer. So to avoid complicated coding, Le Meur used Mailjet’s email marketing automation tools to easily design an email welcome series that was activated upon signup. Welcome series can include a string of different emails that are deployed one after another. Le Meur decided to keep his simple, one email that is written as a very personal message; sharing Le Meur’s own email address and explaining details that can avoid his newsletters hitting subscriber’s SPAM or Gmail Promotions tabs:

Loic Le Meur Welcome Email

Does it work? You bet it does. Compared to the already excellent performance of his regular newsletters, Le Meur has a slightly higher open and click rate on this Welcome Email showing that new subscribers are eager to receive and take action to what Le Meur has to say here.


Up Next

The email list that Le Meur grew from 0-32,000 subscribers in 1 year continues to yield a higher ROI than social media and Search Engine Marketing. For example, this recent Paris-based event was completely sold out, and with a large part of this success thanks to his newsletter. For this reason, Le Meur will continue his concentration on email-first and soon add a number of other list growth and retention hacks including:

  • Email List Segmentation – to reach out to his most engaged subscribers with special updates and additional offerings.
  • Cross-promoting his upcoming platform with other highly successful email based businesses.
  • Testing email ambassador programs where perks, presents and deals are given to those subscribers who convince others to signup to the newsletter.

To be continued.

Stay tuned on the Mailjet blog for the final blog post in our series that will dive into the tech side of how Loïc Le Meur has been able to accomplish such success with email. In the meantime, stay up to date on Le Meur’s journey, follow him on Twitter, Medium and, of course, his seriously awesome newsletter.

Mailjet And Segment Integrate To Uncover Insights In Your Email Contacts And Data

Time out. What exactly is Segment?

If you peeked under the hood of your website or app, would its headers and footers look like piles of code from the Matrix? If so, the upside is that you’re likely using all the cool tools to track your visitor’s activities. The downside is that all those different code snippets are a nightmare to manage, plus they put your loading times at snail speed.   

Cue Segment. Segment is a single API that allows you to collect customer and user data and send it to hundreds of tools for analytics, marketing, and data warehousing. You simply replace your matrix of code snippets with a single snippet of Segment’s code and then connect your tracking tools to Segment. Instantly, your headers and footers are alleviated of their hoarding problem and your loading times warp to lightspeed.



So tell me what this integration does for me? And include doughnuts.

Of course. The integration between Segment and Mailjet lets you do two types of equally powerful actions (with examples illustrated by a doughnut shop – mmm).

Receive data from Segment

Use information feeding into Segment from your other mobile apps and websites to create new Mailjet contacts or enrich existing contacts with additional properties (e.g. name, gender, geography, purchase history). This component is called an “Integration” in the Segment interface. The benefit? Highly segment your contact list so that your campaigns only go to the people most likely to be interested in them.

Example time: You want to send an email campaign promoting your limited edition American Independance Day doughnuts, decorated with an American flag. Thanks to geographical information from your other sources (added to your email contacts via Segment) you can send a targeted email campaign to just those living in the USA, within 20 miles of your doughnut shop locations.

Send data to Segment

Segment can also pipe email event data (e.g. opens, clicks, bounces) from Mailjet into the 200+ other SaaS tools also integrated with Segment. This is component is called a “Source” in the Segment interface. The benefit? Analyse the real effects for your email campaigns.

Example time: You just did a big email marketing push announcing your new cat-shaped doughnuts. By sending the results of this email campaign into your e-commerce tool (via Segment) you can correlate the number of cat-shaped doughnut purchases that came directly from those who opened your email (and how many more doughnuts that user group buys down the line!).

In summary, by using the Mailjet x Segment integration, you can now:

  • Better segment email contacts and send them only the most pertinent emails.
  • Analyze cross campaign performance.
  • See how email behavior affects conversion funnels.
  • Stop retargeting people when they open your emails.
  • Send past email behavior to tools that predict churn detection or upgrade opportunities.

Performing these types of analyses has typically required spreadsheets or custom ETL processes. With the Mailjet x Segment integration, you can capture email data with just a few clicks and no new code.


Cool, is it hard to set up?

Of course not. Setting up the Mailjet x Segment integration takes less than 3 minutes (yes we’ve timed it). You will simply need to activate the integration on both the Mailjet side and the Segment side. The incredible user guide is here.

Love it? Want to try it? Head here to get on the Mailjet x Segment train.

Stop Playing Hard-To-Get with Facebook Lead Ads

So, your newsletter subscription form is embedded on your website. Which essentially means that subscribers need to come to it. But what if, instead of playing hard to get, your newsletter subscription form could come… to your subscribers instead? This is exactly what Facebook Lead Ads lets you do: gain new subscribers by putting your newsletter subscription right in front of your target audience.


So, what exactly are Facebook Lead Ads?

Essentially, Lead Ads are regular looking Facebook Ads that, when tapped on, instantly display a form whose fields are pre-populated with the information that the person has shared with Facebook: email address, phone number etc.. The person reviews the information (and modifies if necessary) and then, in a total of 2 taps, they’ve successfully signed up to receive the price estimate, product demo, or newsletter (wink wink) being offered.


Not bad, but sell me a little more on it.

OK, we get that online forms might not have made you fall off your chair, but Lead Ads are actually a pretty cool opportunity to proactively find people interested in your newsletter and get them to sign up on the spot. Plus, these ads are highly adapted to smartphone viewing format. Facebook says that normal online forms can take 38.5% longer to complete than desktop versions, so Lead Ads can actually make the connection and signup process between you and your customers faster and smoother.

Cool. And how do I use Facebook Lead Ads with Mailjet?

First, start by creating the Lead Ad itself in your Facebook ads account. Do make sure that the fields in your Lead Ads match those within your Mailjet contact list so that the data you’re collecting is easily synced into the correct fields. From here, the power of Zapier comes in. Zapier let’s you connect the apps you love with 500+ other apps. We’ve actually already set up this Facebook x Mailjet Zap for you (because who doesn’t like taking less time to do things?) and you can find it here. In a few simple steps you will choose the Facebook Page from which you will conduct Lead Ads and the Mailjet list you want the new subscribers added into, and voila! Subscriber sync has begun. Here’s an example of how this looks in Zapier:

How Our New Partner Boomtrain Will Turn You Into Netflix Or Amazon

Netflix. How is it that they know exactly what you want to watch after you run out of episodes in your latest series? Not to mention Amazon. You bought that folding mattress and now those Egyptian cotton sheets keep flirting with you online. (Admit it, you kinda want them now…). Love it or loathe it, you can’t deny that they have started getting really really good at suggesting other things you want. That’s because it pays off big time. In the case of Netflix, 75% of what people select to watch is based on their recommendations.


Cool, but where are you going with this?

Using these recommendation algorithms to increase things like sales and viewership is not just reserved for the largest of digital and media companies. Via our new partner Boomtrain, this type of technology is also within reach for medium sized enterprises.


Who is this mysterious Boomtrain?

Boomtrain is a powerful marketing recommendation engine. Using artificial intelligence technology, Boomtrain turns your end user’s behavior into insights, actions and, ultimately, ROI. First, it takes the time to understand your website content on a qualitative level. Second, it analyzes users’ behavior on your website to build a complex graph for each one. Third, it processes that information and uses email (or on-site notifications) to deliver the right content to the right users at the right time. Personalization at scale!


You said this was accessible. Sounds complicated. ?

Don’t stress. Boomtrain does the heavy lifting for you. First, you’ll install a lightweight JS snippet on your website, which allows Boomtrain to track users’ actions, gain an understanding of their interests, and then turn that data into personalized recommendations. Next, you can use the Boomtrain Editor to easily create the emails that will be tailored to your users. And finally, SEND! Example please? But of course:

Choose an email from Boomtrain’s template gallery or import your own:



Personalize your email template by dragging and dropping in Boomtrain’s dynamic personalization fields:



Select your email provider (Mailjet, obvi) and export your dynamic template to that account. Then send emails that automatically populate with unique, tailored content when the user opens the email in their inbox.



Getting kinda excited. And why is Mailjet telling me about Boomtrain?

Mailjet and Boomtrain are officially integrated :-). This means that you can up your marketing game with automated and intelligent recommendations while still leveraging Mailjet’s powerful sending, deliverability and tracking capabilities.Think of it like adding an artificial intelligence layer on top of Mailjet. When you create dynamic email templates within Boomtrain, you can export them directly into Mailjet for sending. This is useful because you have already built up a great sending reputation using Mailjet – which is what helps you land in the inbox. And now by sending Boomtrain-created emails via Mailjet, you can continue to make use of your stellar reputation and make sure your emails get into the inboxes of the users they have been tailored to.

Mailjet Parse API + Zapier: The Tool You Don’t Realize You Really (Really) Need

Imagine having a general “contact us” email address on your website. Most of us do and most of the emails sent here collect dust because filtering through them is tedious. Here’s where the magic of a Parse API starts to come into play.

By redirecting incoming emails to a Parse API email address, the original email (and its contents) can be analyzed, divided and, thanks to Zapier, distributed into over 500+ different software platforms. And did we mention it does all of this without you having to write a single line of code? Cue the sound of Marketers everywhere rejoicing.

To give you a better idea of what we’re talking about, let’s take an in-depth look at someone in HR using Workable. Their team auto forwards job applications being sent to “” to their Mailjet Parse API email address. When the Parse API email address receives the message, it instantly tells Zapier to create a new Workable profile for the candidate. From there, the contents of the email are analyzed and Zapier transfers the information into the designated fields within the candidate’s Workable profile. For example, “fill in the ‘First Name’ field in Workable with the ‘Sender Name’ found in the email.”

Psst – why are we auto-forwarding emails? Why not just have the emails be sent to the Parse API email address directly? Good question. Parse API email addresses are kinda long and ugly. So it’s better to create a nice looking email address and just have its incoming messages auto-forwarded to your Parse API email address.

Here’s how this same example would look if we set this up in Zapier:

  • Within Zapier, go into “Make a Zap.”
  • For the Trigger, select Mailjet > Parse Inbound Email.
  • Follow the instructions to create your Parse API email address.
  • For the Action, select Workable > Create Candidate.
  • Select which parts of the incoming email (i.e. sender name, date, body of email, etc.) you want to be captured and where to put each part within Workable.
  • Now start sending job application emails to your Parse API email address and see the results!



So this is starting to sound pretty cool, right? And once you start parsing, you can’t stop… Here are some other examples of how parsing makes your work life more efficient:

  • Send a notification to a Slack channel when you receive a new email to your generic company “contact us” email address.

  • Automatically open a new lead and transfer the contents of an email sent to your generic “request a quote” email address into Salesforce.
  • Have the responses from an email survey you conducted put into their appropriate columns in a Google Sheet.

    Craving more details? Here’s your direct access to the Zapier + Mailjet band wagon.
    And if you come up with your own amazing Parse API use cases, we’d love to hear about them.  Write us and we’ll update this post with your wild and crazy parses.

    Happy sending… and happy parsing!

Here’s What Happens When Mailjet Talks To Other SaaS Platforms via Podbox

By 2018, 27.8% of the worldwide enterprise applications market will be SaaS-based, up from 16.6% in 2013. What does this boil down to? You’re using A LOT of SaaS applications to run your business, and you’re only going to start using more.

If you found yourself sweating from just reading that sentence, you’re not alone. As vital as SaaS applications are to running your business, analyzing data across multiple platforms can be daunting, time consuming and can cause you to gloss over important business opportunities. 2015-10-11 20-28-20

That’s why, we’re now integrated with PodBox, to put master data management at the heart of Mailjet and your other SaaS applications. Think of PodBox like an automated hub that gets your collection of SaaS applications talking to one another on a continuous basis so that no matter what tool you are in, you’ll have a cross-functional view of your entire business.

Let’s look at some examples: 2015-10-11 20-33-39

Do you have a sales team? Then imagine seeing which of your leads are engaging the best with your email messages. Or start tailoring different messages to your most frequent openers and clickers. 2015-10-11 20-30-03

Do you talk to a lot of customers? Imagine having your Mailjet email list(s) being automatically updated as new customers are added into your CRM contacts. Or having your CRM contacts automatically updated when email recipients unsubscribe (to have a holistic internal record of a customer’s engagement over time and avoid accidentally re-emailing them).

The combinations are endless. The real advantage though is that by having information automatically shared and synchronized between the different Saas platforms, you can quickly:

  • Gain insight into what’s working in your company and scale.
  • See what’s not working in your company and resolve it.
  • Make your email marketing more agile and personalized.
