1. New capital increase for Mailjet and opening of a New York office


    The French startup Mailjet is proud to announce that it has raised 2.2 million euros (3 million dollars). This new capital increase will accelerate the growth of the company for international expansion and product development.


    This action follows the recent opening of an office in New York, led by Anthony Marnell, Vice President, North America at Mailjet. Anthony is a TechStars alumnus and has advised multiple startups in the US.

    “This new capital increase will allow us to strengthen our sales strategy, onboard larger accounts and continue our international growth”, says Alexis Renard, CEO of Mailjet. “20% of Mailjet’s revenue already comes from the United States. A physical presence was mandatory. We chose New York City for its dynamic and growing startup ecosystem.”

  2. From Tel Aviv to Paris: 2 Israeli guys in France


    We met Matan Markovics and Almog Luz last May during a hackathon in Tel Aviv. Both of them are developers, very active in the local startup community. We were impressed by their creativity and loved the way they used the Mailjet API to conceive CyberQueue, an online queue management tool (lines in public services seem to be a major issue in Israel). That is why we invited them to discover the Parisian tech scene. Matan accepted to give us some feedbacks about this experience.


    How would you compare the Paris startup community to the one existing in Tel Aviv?

    What impressed me the most was the fact that there is not one but multiple tech communities in Paris. There are clusters, accelerators, studios, co-working spaces… where you can find several different startups that work together. And those small groups of people full of ideas work together on an even larger scale. With this kind of process, everybody know what is going on and can establish new partnership with local companies. It is a different kind of emulation than what exists in Tel Aviv. And I like it!

    During your Parisian trip, you have met French developers during another hackathon, Hack – Make – The Bank. What were your impressions?

    The participants of this event were asked to develop and work on projects about banking security and other financial issues. I liked that idea a lot. Really cool projects were conceived that day. In fact, I think that is the essence of what hackathons should be: places to create new uses of existing programs, codes or APIs.

    It reminded me a lot of what we did in May. When you participate to a hackathon, you have very short time to find clever solutions to answer the problem that has been asked. In that kind of context, we, developers, like to use quick and easy APIs. That is why we choosed the Mailjet’s API when we created CyberQueue.

    What did you learn during your stay in Paris that could have improved the way you work today?

    I think that Paris is the perfect city for startups. Like I said, the tech community is already established and strong. Mailjet is a good example of this, as a matter of fact! It started from scratch and now the company is one of the leaders in marketing and transactional emailing. I like to think that its growth and rise to success are linked to this dynamic Parisian environment. So, yes, we can learn one thing or two from you guys! That is why I intend to come back in France soon!

  3. Safer Internet Day - How Mailjet helps


    Safer Internet Day is today. We, at Mailjet, want to use this opportunity to demonstrate that Email as a Service platforms can actively fight against phishing, a threat to a safe Internet.


    Let’s take a look at the latest study made by the Anti-Phishing Working Group:

    For the first half of 2013 alone, they identified 53,685 phishing domains. 12,173 of which were directly registered by phishers, twice the number found in the second half of 2012. The most popular phishing target was Paypal, with 13,498 attacks, representing 18.3% of the total.

    How does Mailjet and other Email as a Service leaders help to overcome this problem? At least three barriers are set up.

    Let’s take an example. XYZ Corporation uses Mailjet to send its emails. One Wednesday evening the phishing mafia sends emails claiming to come from the company’s domain, xyz.com. What they don’t know is that Mailjet urges all customers to use SPF…

    Barrier 1: Sender Policy Framework (SPF)


    SPF allows the owner of a domain to restrict sending of valid emails by specifying a list of valid IPs. He does this by adding a TXT record to his domain, which is kind of a meta information everyone can see. The content of this TXT record is a list of IPs which can be used to send valid emails. Each time a mail server receives an email from this domain, it will look up this TXT record and check whether the IP from where the email comes from, is included in the list of valid IPs. If this is not the case, the email can be marked as a phishing or spam attempt.

    Since the emails sent by the phishing mafia claim to come from xyz.com but have an IP address not included in the SPF list, the email gets filtered out and no harm is done.

    One week later, the phishing mafia learned about SPF and told its developers to change the sender IP address so that it matches an address included in the SPF filter.

    Again, they missed something. Every Mailjet customer gets plug and play DKIM.

    Barrier 2: Domain Keys Identified Mail (DKIM)

    DKIM allows a domain owner to use the power of asymmetrical encryption to prevent misuse by phishers and spammers. Asymmetrical encryption means that one generates a pair of keys, one of which is public and the other is private. The private key has to be kept away from the public and is used to generate a specific electronic signature for each email.

    This signature is basically a string of characters in which information about the content of the email is encrypted.

    The public key is added as a TXT record to the domain. Now, each time a mail is sent, it gets a signature. When an email server receives one of these emails, it checks the domain records for the public key entry. The public key tells whether the signature was made by his brother, the secret key, or not. If it wasn’t the email can be considered a phishing or spam attempt.

    Barrier 3: Email Pattern Filters

    Having failed twice, the only hope for the phishing mafia is to get access to the XYZ web server. Hopefully our friends from the Server Security Industry made a good job, but for sake of a good example lets say the mafia succeeds and now has full access to the XYZ web site, at least for the crucial first 12 hours because this is where most of the money is made by the phishing mafia. The mafia now can send emails and neither SPF nor DKIM cause alarm because both the IP addresses and the signature are correct. But this also means that emails are now sent via Mailjet’s SMTP Relay.

    Even so, the phishing mafia’s emails are still passed through Big Data algorithms like Bayesian Inference. Their purpose is to recognize frequency and content patterns in real time. Most likely will the phishing mafia send a different amount of emails than XYZ Corporation used to do. The content of the emails will differ as well. If these patterns diverge by a certain amount, an alarm is caused and emails are put on queue until the issue is resolved. This gives XYZ Corporation enough time to detect the attack and take measures.

    Invisible actions for the end user are undertaken every day, so that he can enjoy an always safer Internet. Mailjet brings its own contribution to the task.

  4. Meet Mailjet’s Deliverability Pilot


    Do you ever wonder who stands behind Mailjet? Mailjet serves over 16,000 global clients and all the work isn’t done by our robust cloud platform alone. We have a dedicated team of experts that maintain continuous compliance and improvement of Mailjet’s services, aligned with industry best practices. Every now and then, we take a moment to take a closer look at the folks who constantly strive to improve your email delivery. Today’s turn is in fact having his 1 year anniversary at Mailjet as we ushered in 2014, and we are happy to have him on board!

    Udeme Ukutt, Deliverability Director

    Udeme steers Mailjet’s Deliverability & Abuse Team operations with a special quest: ensure consistent aligned with day-by-day global deliverability best common practices. His team continuously handles multiple responsibilities around the clock, like:
    • 24 x 7 abuse desk ops across multiple continents to combat anomalous (spam & phish) activities & stop the bad guys

    • continuously analyze how legitimate, solicited good email get delivered to those who want it - successfully into their inbox folders.

    Since deliverability is a core, complex and important topic, Udeme has one of the busiest jobs at Mailjet. Nevertheless, he is given a few moments to give some extra insights:

    Maggie: You ADORE deliverability and love everything that comes with it. How did you find out this was your thing?

    Udeme: Someone asked me one day, ‘do you love math? Love computers?’ I said, ‘Yes!’… and here I am, breathing deliverability compliance day in and day out. Over the years I’ve learnt & experienced delivery ops on both the sender and receiver sides of the ladder. Nevertheless, I strive to contribute positively even more!

    The average Deliverability ‘peep’ analyzes A LOT of data 24/7, which made this career path a perfect match for me. Funny enough - I always loved math & statistics since I was a little kid.

    Maggie: What is your typical day at Mailjet like?

    Udeme: Every day has something exciting, something that calls for an extra cup of coffee. In fact, each day is unique like the other because we’re constantly progressing with industry trends. We’ve to do that because the industry and the average ISP/receiver consistently maintain their anti-spam filter algorithms, and in parallel we’ve to continually adapt and analyze.

    Like many have said, deliverability is an ongoing mission that’s got no magic solution, no silver bullet! It’s an ever-changing task because we encounter new senders, new data, changing algorithms … daily!

    Maggie: Part of your job is reputation management. What does that mean?  

    Udeme: Reputation management’s something with major impacts on deliverability. ISPs such Yahoo! & Gmail… down to Orange, etc observe the average sender’s reputation to determine ‘trustworthiness’.

    If a spammer uses Mailjet to deliver bad email, this can harm Mailjet’s reputation - as well as the overall reputation of our senders. That’s the reason why its not only in our highest interest - but our senders as well - to establish, enforce and maintain the tightest antiabuse algorithms as possible to protect our reputation.

    Maggie: How do you detect spammers?

    Udeme: Basically we analyze all deployed emails real-time and search for unusual deliverability issues that may trigger off spam indicators. A negative indicator may be a high volume of bounced emails; or high complaints; or vice versa. Primarily, legitimate senders use stuff like properly authenticated mail, high quality solicited lists (ideally made up of confirmed opt-in contacts. Naturally, since all recipients on the list consented to receive emails from the sender, the bounce rate should be low.

    Spammers usually send their emails to what’s classified as third-party data (purchased, rented, etc). Spammer activity is reflected in their sender’s email stats … high rates associated with bounces, spam, complaints, etc. In rare cases, it may happen that a legitimate sender encounters a deliverability issues too. If that’s the case, we would support a legitimate sender with expert advice on how to improve their reputation.

    Maggie: How can senders improve their deliverability? 

    Udeme: To mention a few common ones that help receivers and ISPs to increase mail stream ‘trust’, spot-check these occasionally:

    • Ensure you (properly) implement authenticate email using SPF and DKIM. DMARC is a new technology that’s being recognized more and more, industry-wide.

    • Confirmed opt-in list acquisition practices are strongly recommended as opposed to a single opt-in mechanism.

    • Place focus on message design, content, structure - as well as frequency and relevance of your messages

    • My guess is that you wouldn’t want to fly with a jet plane that hasn’t had a security check either, would you? Or … you’d want to fill it up with proper fuel too, right?”

    Maggie: Thank you for those helpful insights and your precious time, it’s great to have you on board! … and now let’s go back to conquering inboxes. :)

  5. The 3 Places to Be This Week: Lille, Berlin & Munich


    As it often happens, a short period of time condenses an impressive number of very nice events. The prize goes to Berlin, which culminates three startup competitions in only a few days. We can’t be everywhere at once, but nothing will stop us from trying!

    Take Off Conf in Lille, a developer’s conference

    This great event in English is taking place in north of France. This gathering is aimed at developers. There will be a lot of great names attending, so if you are part of this target audience, you should seriously consider coming. We will be there (we’re sponsors after all!). Don’t hesitate to send us a shout out on Twitter: @Mailjet or @Elie__

    Berlin, the 1000 awards city!

    It all starts on Tuesday the 15th with The Next Web Awards. The ceremony will take place in a location well known to Berlin clubbers: the Chalet. If you speak French, you should note that there is a French version of this event that you can nominate us for. ;)

    On Saturday the 18th, Hy Berlin begins, another competition that will welcome some prestigious guests. Among those present are the founders of YouTube, GigaOm, Reddit, CrunchFund, 500 Startups, etc. Obviously, we aren’t going to miss this one!

    And because when it rains, it pours: The Europas will take place on Tuesday the 22nd, sponsored by TechCrunch’s Mike Butcher. We will be there too (@qnickmans, @wiloo, & myself).

    The German version of Le Web in Munich

    The DLD - Digital Life Design is a huge event devoted to the digital ecosystem. If you are looking for Mailjet there, you will find us personified by Pierre-Simon, who knows us very well and will be representing us on this occasion. Don’t hesitate to reach out to him.

    We are available to meet with you!

    We have planned to meet the maximum number of people possible during our brief stay in the German capital: we are actually looking for a Dev Evangelist based in Berlin. If you are interested, or simply want to exchange a few words with us, feel free to send us a message via the above mentioned Twitter accounts.

    Have a good week and we hope to cross paths soon! (In any case, we are trying our best!)

  6. Case Study: Mailjet & Wizishop


    Wizishop is a French eCommerce Platform which chose to integrate Mailjet. They are announcing their first round of funding today: 300K euros with Jaïna Capital and Kima Ventures. As this partnership has been a great success from every angle, it seemed interesting to publish a case study.

    This presentation is very interesting, especially if you own a service that could use Mailjet’s technology to create more value and generate new revenues. This case study actually explains how the partnership works, from both a business and a technical point of view. Wizishop is an eCommerce platform, but the same principles could have applied for a CMS, a CRM, or any SaaS. 

  7. [Press Release] “French Startup Mailjet Raises $3,3 million”


    This tweet says it all. Beyond this, we had a crazy day at Mailjet. Our service got featured on The Next Web, TechCrunch, Gigaom, Les Échos etc. So you may already have read about it, but in case you are curious here’s the official Press Release with all the details. And yes, pay attention to the last sentence: mailjet is hiring ;-)

    Mailjet, the cloud based email platform, has raised $3.3 million from Alven Capital and private investors.

    Launched in 2011, the innovative cloud platform enables users to manage the sending and tracking of transactional emails sent by web applications and eCommerce platforms. Mailjet delivers a reliable and high-performance tool avoiding complex and costly-to-maintain internal solutions. The company is also tackling the optimized management of deliverability, aiming to avoid spam flagging of legitimate email (globally, 1 in 5 legitimate emails do not reach their intended recipient).

    The intuitive user interface is key to Mailjet’s success. With a simplified approach, Mailjet gives accessibility to functionalities which, with the previous generation of tools, were reserved only for experienced users. The solution fully integrates the users’ business processes. The platform has already attracted over 10,000 active clients of all sizes in only 18 months. 

    "The technology we have been working on for 2 years lays the foundations for a robust and scalable platform that will allow us to offer innovative features to our users," explains Julien Tartarin, CEO and Founder of Mailjet. "Our team is focusing on the user experience. It’s our passion: to provide a simple and intuitive interface. We couple this with a powerful and flexible API, for both developers and large accounts." 

    Quentin Nickmans, co-Founder, adds: “The funds raised will allow us to accelerate our commercial deployment for the next 2 years and to continue structuring the company to support our very strong growth while maintaining a very high level of service. We are also recruiting on an international scale, to be ever closer to our customers, the ISPs and the developers, in Europe and in the rest of world.” 

    "The market is huge and is just booming" explains Thibaud Elzière, co-Founder of Mailjet and Founder of Fotolia and eFounders. "There aren’t any more (sensible) startups that launch without a service like Mailjet. The cloud is a long-term trend and deliverability management will only be getting more and more complex in the future…." 

    This is Mailjet’s first institutional funding round. Alven Capital invested $3.3 million in this fund-raising, together with Laurent Asscher and eFounders who completed the round. The company previously received $300K from e-Founders, to finance its R&D. 

    Raffi Kamber, Investment Director at Alven Capital : “Mailjet demonstrated the relevance of its solution by gaining the loyalty of more than 10,000 clients. The quality of the team and the ambitious nature of the project quickly convinced us. We are very proud to support Mailjet in its growth.” 

    Mailjet is hiring across multiple job functions: business development, marketing and engineering. Interested candidates should visit their dedicated job page.

  8. Padiact Helps You To Get More Subscribers


    Here’s another great integration! We’re always very excited of these tools that harness the email channel in a smart way. 

    What is Padiact about? 

    Instead of aggressively asking all your visitors to subscribe to your email lists, ask only the visitors that are most likely to. 

    Padiact allows you to target visitors based on type (new visitors vs returning visitors), recency, referrers, time spent on site, number of products viewed or articles read.

    How to proceed? 

    Connecting PadiAct with Mailjet, couldn’t be easier. All you need is your Mailjet API keys:

    Once you have them, just select Mailjet as your email service provider inside PadiAct’s campaign settings and use them to connect to your account and retrieve your lists.

    Don’t forget to setup the targeting rules for the segment of your traffic that is most likely to generate leads. Then, just define a custom message for that segment of traffic to get them to offer you their contact details and you’re good to go.

    Your leads will fly in directly to your Mailjet account where all is left for you is to setup some juicy email campaigns for your targeted leads.

    Padiact is great: try it now!

  9. Two years already, and the best is still to come!


    The month of August is traditionally very calm. It is as we approach September that things begin to start up again. For Mailjet during this period, there was a time when things were just getting started for the first time…

    Mailjet celebrates its two year anniversary!

    If the service was officially launched in February 2011, the first lines of code were written in the summer of 2010. Our founder, Julien Tartarin had quit his job to devote himself full-time to the Mailjet project. The rest of the team took their nights and weekends to work on it. Then, little by little, the number of collaborators grew, along with the number of users!

    This is a big thank you to all of our users, to those who are joining us now and to those who turned to us in the beginning of this great adventure.

    Where are we now?

    We are pretty  proud of our presence in France: people are really starting to get to know us! In the other countries, word of mouth is spreading too… overseas, certainly, but also in Europe: Great Britain, Spain…and Germany.

    Preparing the next step: The Berlin Escapade!

    A part of our team just returned from Berlin. For the past decade or so, the German capital has been buzzing with life by attracting young Europeans in search of exciting art, music, and nightlife. Today, Berlin is also a center of entrepreneurship: hundreds of startups have been created there in the past few years. Its combination of a dynamic ecosystem and minimal costs has spread across and benefited all of Europe.

    The cost of living in Berlin is not that high, so you can get started rather inexpensively. Clearly, Mailjet has an opportunity to take here: so much is happening! At least, that’s what we found at the different events we attended last week.

    As anniversaries are also an occasion to look toward the future, here is a quick report: displayed in images!

    Campus Party Europe & Tech Open Air Berlin

    These two events also occurred while we were there, in true Berlin-style: one at Tempelhof, an iconic former airport, and the other in a space usually used as a nightclub. The result? Something you wouldn’t see anywhere else in the world.

    Tens of thousands of developers crammed themselves into tents in a gigantic hangar. 

    The result was quite impressive. You can find all of the photos on the event’s Facebook page.

    The next day was devoted to Tech Open Air…and we still had the feeling that we were in an offbeat location.

    The entire ecosystem of Berlin startups was there…The next day, a series of satellite events continued to amaze us, like our breakfast on the top floor of the Axel Springer tower.

    Seeing the liveliness and energy of this ecosystem, it is clear that much remains to be done: thousands of opportunities have emerged for us. Two years is short indeed, but this is just the beginning, given all that’s left for us to do!

  10. Need To Explain Mailjet To Your Friends?


    I’ve just finished a nice presentation explaining briefly what we do and where our added-value is. Check it out! It is quite interesting :-)
