1. 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!

  2. 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.

  3. Mailjet loves galettes!


    Yesterday, the Parisian Mailjet team attended the first edition of the French Tech Galette which took place at NUMA, one of the biggest co-working places in the world. During this event, we had the opportunity to meet interesting and motivated members of the Parisian tech family and, of course, to enjoy delicious galettes. But… wait a minute… what the hell is galette?


    Photo by Laure Lucchesi

    Galette in a nutshell

    French pastries and desserts are well known all around the world, thanks to various people: Marie-Antoinette and brioche, Amélie and crème brûlée, Kanye West and his damn croissant… but galette has not gathered the same international fame as those renowned delicacies.

    Galette is a traditional dessert that most of the French people eat during Epiphany, which happen the first week of January. This cake, made of puff pastry filled with almond cream (the frangipane), contains a trinklet, the fève. Whoever gets the fève in their slice of galette becomes king or queen.

    Frangipane and tech people

    Well… the French Tech Galette was exactly about that: a huge bunch (we were 500 attending the event) of tech people eating galette and drinking apple cider in a casual atmosphere, celebrating the great year to come, and yelling “I’ve got the fève! I’m the king!” every now and then. You even could have seen Shubham, one of our developer evangelists, walk in the crowd like a king…

    Mailjet is proud to have sponsored this fun and warm event. The fact that so many people assembled so quickly (it took a week to create and invite this party!) highlights Paris as one of the most active cities in the world to innovate and start tech based companies. At Mailjet, we like to think that we contribute to that entrepreneurship state of mind.

    French Tech Galette… out of France!

    You missed this weird in a fun way event? Don’t panic! You’ll be able to catch it up and meet the London based Mailjet team January 22, during the Londoner French Tech Galette! Once again, we’ll eat cake, wear paper crowns and meet great people. So do not hesitate and come to meet us!

  4. 3 Facts About Email Designers And What They Do For Us


    I think we do not give enough credit to people who conceptualise, design and ship legitimate emails to our inboxes. Email designing is like a complicated art, due to industry restrictions and the reality that most people take emailing and their own inboxes very seriously. This is what I gathered from the 2 day conference organised by Litmus. I have been wondering since, when and if, things will improve in this domain. Cross-browser email design is today in a much worse spot than front-end development.

    What’s happening to the email designer world?

    Late 2013 I attended the London email design conference, as the title says it is a conference about designing emails, email marketing challenges (mobile, browsers) all wrapped around a friendly community. A lot of information has been shared. Many give it for granted that making a marketing email look nice only takes a matter of minutes but in reality, it’s a total different story.

    Have you ever payed attention to the amount of time that email marketers put into researching the colors, images and text that is sent out to hundreds of thousands, if not million of users every day?

    It's animated click the URL above to see the live version

    Take a look at this email right here, looks catchy and efficient, wonder how many hours went into this

    Whether it is a marketing email with some offers to engage activities, or a transactional email with a password reset, someone did spend the time to code that email, the colors, the text, the layout, the pictures or other images.

    Email designers belong to a weird group of people as they are praised by some, hated by many and mocked by others.


    The work of an email designer can raise the engagement between the customers and the company. If an email is well designed, well presented (subject, body preview) and its content smartly portrayed, it leads to an increase of the open rate. This means it could be converting a customer into making a sale.


    Customers sometimes receive newsletters which they’re not really interested in. This leads to an uprising anger, as they feel flooded with tons of newsletters from different vendors. A marketing email is not just a pretty email created to annoy its community, it’s a vehicle of transmitting important information to a wide userbase, something that is retained in your inbox and archived, that you can always get back to.

    Laughed at

    Front end designers that create beautiful HTML5/CSS3/JAVASCRIPT compliant websites might tend to mock the art behind the creation of an email with inline style codes, that is so hated and hard to maintain. A lot of times when claiming to be an email designer, people automatically associate you with one of those guys that create those flashy, spammy emails: unfortunately that’s something built into our society and which is hard to move away from. In the past a lot of the emails sent did not follow the strict set of rules and regulations that we have nowadays. Hopefully one day this association with spammy marketers will vanish.

    A challenging world

    Creating a good newsletter design is something that isn’t for the faint hearted. There is a need to fully understand not only about one’s company branding, but also some amounts of psychology to gain an insight into how humans interact with computers and its projected visuals. Although statistics prove that using red-ish buttons will increase your click rate of 25% or above, this is not as simple as adding 1+1.

    Email design proves to be particularly challenging when compared to web design for a lot of reasons, the most crucial being the lack of support for Javascript, font personalisation, email clients rendering emails in different ways, deliverability issues if rules are not respected.. and many more.

    If the lack of all the above, the technology and flexibility given to web designers wasn’t enough, you need to factor deliverability in all the above. Emails need to be permitted to reach the inbox that is where the opt-in laws come in place. If you are serious about deliverability you need to consider a lot of factors: HTML standards, Hosting images on the domain name sending the emails and a few more

    Have you got any email design war-stories to share? The world out there is grey for people involved in the creation of attractive newsletters. If so please do so in the comments!

  5. 8 Lessons Learned From Yahoo’s Bold Move Of Recycling Inactive Email Addresses


    Since Marissa Mayer was appointed CEO, a lot of things have changed at Yahoo. Banning remote work was one of the big moves, but let’s focus on a particular event that impact us more directly: Yahoo Mail has actually been overhauled. Beyond the radical redesign and the launch of a new mobile app, a big decision was taken: Yahoo decided to recycle inactive email accounts.

    Much ink has been spilled on this issue. Now is the time to put things into perspective. What happened exactly and how does it impact you either as a sender or a recipient? Here are 8 key takeaways everyone should be aware of.

    1- Recycling inactive email addresses was part of a much bigger plan: the Yahoo Mail relaunch

    In Marissa Mayer’s portrait published in Business Insider, we learned that putting out a new version of Yahoo Mail was an absolute top priority. The new CEO even personally managed this project. The team working on this went under a lot of pressure. Sources report that what they achieved in a few months used to take them more than a year. You can tell the ex-Google managed closely the Yahoo Mail redesign, simply by looking at it

    Some members of the team were a bit upset with this micro-management: it ended up with the Lead Designer leaving for Google, while the Yahoo Mail Product Manager went to Disney. Marissa wanted to push her project at any price: the timing was more important than anything else.

    All this tells a lot about the context in which the decision of recycling email addresses was taken.

    Announcing that inactive accounts would be made available to other users was actually an angle to get press coverage and spark the interest of the public for the new Yahoo Mail. It worked quite well, but maybe not in the way Marissa was expecting it to be. Wired and quite a few security experts immediately backfired. Keep on reading to learn why.  

    2- Nice email usernames can be a competitive advantage but there are some downsides

    Offering more choice is perceived as a plus when compared to other webmail providers. This is how the announcement was marketed: “yourname@yahoo.com Can Be Yours!" This sounds attractive, for sure.

    Gmail, for example, doesn’t recycle inactive addresses and news users often have to integrate numbers in their email handle. Security prevails even if this usernames scarcity becomes problematic. So in most cases, offering more choice is relevant. 

    However, I’m not really sure I would like to get the johnsmith@yahoo.com or any popular similar handle. Everyday, millions of people provide fake email addresses to access a service or download something. Are you sure you want to own one of these “popular” addresses? Quite a few users reported that they eventually shut down their new email address and went back to the old one.    

    3- Recycling inactive accounts was also a way to re-engage old Yahoo Email users

    Think about it: people who want a convenient username were not the only ones concerned by Yahoo’s announcement. Any person with a Yahoo account has been impacted and the message delivered to them was: “we recently launched a new interface, and by the way, if you don’t login/authenticate, you may lose access to your ID.”  

    Do you think this is exaggerating? Accessing your email via POP/IMAP isn’t enough - but need actual authentication via a web platform.

    From the marketing side, this seems to be an excellent way to relaunch. However, some security experts criticise this process and denounce a risk shift: “Yahoo transferred the burden of responsibility to the customer by requesting that the person log in to ensure the account remained active.”

    4- Security: when you recycle an email address, it could end up with a creepy user report

    Yahoo defines an “inactive address” by looking at the user engagement (recent authentication, email activity, etc). But how about the sender’s perspective? A true inactive email address would be also one that doesn’t receive any email from anyone.

    When an email address is recycled, a lot of the senders may not be aware of this change. Newsletters, notifications, or even personal emails can be sent to an absolute stranger. As soon as some inactive addresses were recycled, users reported issues:

    "I can gain access to their Pandora (or Facebook) account, but I won’t. I know their name, address and phone number. I know where their child goes to school, I know the last four digits of their social security number. I know they had an eye doctor’s appointment last week and I was just invited to their friend’s wedding," Jenkins said. "The identity theft potential here is kind of crazy."

    It is worth mentioning that Microsoft also recycles email addresses. Hotmail has had this policy for years, and they recently extended it to Live ID and Outlook.com. Their terms of services don’t clearly define this policy so they also went under a lot of criticism.

    Because it is an ongoing process, there is no massive impact. But this doesn’t mean they don’t face any issues: some users also report problems.

    5- Recycling addresses is counter intuitive for an email service, as it might attract spammers

    Webmail and email providers in general always have a big challenge: limit the number of abusers. This is why you have captchas when you create an email account. Think also about Gmail. Remember back in the early days? It was an invite-only service.

    One of the reasons was that they we providing much more storage capacity than their competitors: 1Go VS 2-4Mo for the others (because Gmail launched on April 1, people even thought this was a joke!). So they needed time to make sure they would be able to scale out. But this was not the only reason.  

    In Founders at work, Buchheit, the Gmail architect is interviewed:

    Interviewer - What was the idea behind the invitation-only signup?

    Buchheit - There were few different factors. (…) it controls some of the abuse, by making it harder for, let’s say a spammer to get 10 million accounts, which would be bad”

    Keeping a clean user base is strategic. From this perspective, the Yahoo move sent an odd message to potential abusers: “get recycled email addresses and you might be able to access some personal data and credentials.”

    My guess is even that quite a few “reassigned” addresses could potentially be chased for phishing (name of companies or real people…).

    6- Tough time for the senders: Old email addresses are now more dangerous than ever

    Until recently, a “recycled email address” used to designate a special kind of spam trap:

    "These types of addresses frequently trap legitimate senders with weak list hygiene and data quality practices. Typically, an ISP could/may turn off an abandoned/inactive email address after x period of inactivity - which produces an ‘unknown user’ bounce code. At some point, the ISP will reactivate/recycle the address, hence converting it to a spamtrap; eventually allowing the ‘trap’ address to receive messages (Source: Return Path).

    Today, it also designates an old email address that was reassigned to a new user. You might think this is good news for the senders, but it’s not. The recipient will certainly click the “report as spam” button for all the emails for which he didn’t subscribe himself, which is very bad. This is one of the reasons why Yahoo added a new button: “not my email.”

    7- If senders don’t clean their list for 30 days, they might end up emailing random people

    As soon as the criticism bursted, Yahoo reacted: “We will have a 30-day period between deactivation and before we recycle these IDs for new users. During this time, we’ll send bounce-back emails alerting senders that the deactivated account no longer exists.”

    This means that cleaning your lists is more important than ever. Infact for the average sender, you should (and must) remove all inactive Yahoo email addresses from all lists. But - if you regularly clean single/confirmed opt-in lists properly built, you should be fine.

    8- Bold business driven moves can end up with the creation a new internet standard

    Because this 30-day period didn’t satisfy the security experts, Yahoo worked hard to build a new standard for an email header: Require-Recipient-Valid-Since  (RRVS). It works the following way:

    "If you submit a Facebook request to reset your password, for example, Facebook would add the RRVS header to the reset email, and the new header would signal to Yahoo to check the age of the account before delivering the mail. If the values don’t match, the email would bounce."

    Of course, if you send these kind of emails (transactional), etc & your list(s) contain Yahoo subscribers„ you should consider using this header.

  6. 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. :)

  7. Gmail Images Displayed By Default: What’s The Impact For Our Customers?



    A few days ago, some observers noted that Gmail was now caching all images contained within emails. Yesterday, an official announcement by Google gave us the real explanation: the famous webmail will now display all images by default. This change is excellent news for email marketing. There are however a few downsides you should be aware of. One particular issue was raised: the tracking for multiple opens. Our team immediately implemented a workaround. 

    What is this big change about?

    Remember the message below? This is what Gmail was displaying by default, for any email containing images. The recipient had to click to see the full message. This is no longer the case: from now on, all images will be displayed by default.


    Google didn’t display the images to protect its users against malicious content. To bypass this risk, Gmail decided to copy all the images on its own servers, in order to ensure security. Of course, this comes with a few side effects. 

    The end of geolocation and user agent tracking

    Many services (Mailjet included) have the capability to display the geographic location of the recipient when they open their emails.

    We base this information on the IP address the images are downloaded from. Now, however, because all images are sucked up by Google, any Gmail and Google Apps user will appear to be at Mountain View, in California… 

    We also indicate which User-Agent was used to access the email: just like for the geoloc, the fact that Google now sits in between us and the recipient keeps us from obtaining this information.


    There is no way to bypass these two unfortunate side effects. Of course, we are looking for a workaround, but there isn’t much hope. Everyone faces the same problem. 

    You should therefore expect the proportion of “other” user agents to surge. The number of recipients based in California should also increase…

    Open tracking: with Mailjet everything works as usual

    The opens statistics are also calculated by using an image: a transparent and unique pixel is placed into the message. Each time the recipient opens the email, the image is downloaded, which allows us to track opens. 

    Gmail’s caching doesn’t keep us from tracking the unique opens, since the pixel must be downloaded at least once, so no worries here.

    However, some email services are no longer able to track multiple opens: indeed, once the pixel is in Google’s cache, there is no way to detect if it was re-loaded or not. 

    Our deliverability team immediately deployed a solution to counter this problem: multiple opens are still accurately tracked with Mailjet. 

    The solution to track multiple opens 

    The trick consists of implementing a particular HTTP header for this transparent tracking pixel: “Content-Length:0”. This keeps Gmail from caching the pixel, and forces a retrieval of the resource each time the email is reopened.  


    This solution also has an adverse effect: it generates a link that produces a 500 error on Google’s side, which means there is no guarantee that Gmail won’t update its system and kill this workaround at some point. In this meantime, it works with us!

    Conclusion : overall, it’s positive

    In any case: unique open tracking is not impacted and nothing indicates that this will ever be the case. The fact that images are displayed by default is terrific for the email marketing industry. 

    This also shows how email is under constant evolution: this is very exciting for us. 

  8. Full Frontal and some ideas to improve conferences


    The goodness: FullFrontal.

    Full Frontal (FF) is a conference for web developers where Javascript is the core topic of discussion. I have attended this event at the start of November. A number of interesting topics such as “CSS3 animations with no Javascript”, “Javascript optimisation and compression on the browser side” or the soon to be released “ES6 Javascript engine” are brought to the stage and thoroughly presented. There were more presentations but I particularly recommend reading the slides provided for the ones mentioned above. The quality of the presentation and talks however just left me speechless: It delivered, oh yes it did.

    Unlike other conferences I have been to before, this one was held in a movie theater in Brighton, a beautiful city during the summer, in the south of the United Kingdom.

    The FullFrontal talks

    I was lucky to be in the third row, the chairs were supercomfy and I really enjoyed being able to really be captured in awe by the presenters: Each presentation was announced with a little bit of humor by Remy Sharp, one of the organisers, who explained how he met the presenter and why he believed that particular person would fit the conference’s theme and layout.

    I was particularly amazed by the young presenter, Andrew Nesbitt, (who now works at Github) that explored the possibilities of using NodeJS on robots.

    He presented an Xbox-controlled lego mindstorm robot to dispense food to his rabbit, along with the Troll-o-copter, a NodeJS controlled quadcopter that uses the frontal camera to recognize human faces and applies the “troll-face” effect on them!

    Also really impressed with the closing presentation by the legend Jeremy Keith, Time. I was speechless, a talk regarding the impact of time on the internet and our digital-connected future.

    Conferences - what could be improved.

    Like many other conferences the problem is that tickets are served by some online company and they just run out in matter of seconds, the Websummit’s launch party event (Have you read our blog about the websummit?) for example was sold out in 15 seconds. Surely there are a lot of people that are eager to get a ticket but is this system fair?

    Lately I have seen more and more event managers release tickets in batches, once a week over a period of a couple of weeks preceding the event. This approach is more humane I find, everyone multiple chances to get a ticket. I also find quite inappropriate to have early-bird tickets and late-birds tickets. Late-bird tickets’ price is double or triple the amount of the early-bird one: Seriously not everyone knows about an event 5 months in advance!

    Legacy data

    I would also want to raise another issue.

    With the price I have been paying to attend some of these conferences, I am expecting there should be at least some kind of video/media coverage at the event. This allows people to go back and be able to view what they’ve missed and, of course, the great talks. Not immediately, but do have that media out there.

    Not everyone does this, releasing and sharing content, I really think it is a shame. Back in the days there were scribes that would “transcribe” the “knowledge acquired” so that it could be passed on to our future generations. Nowadays everyone just tweets. It’s not possible to pass on knowledge with some tweets: They’re too volatile.

    This is where videotaping can really help, and like the FullFrontal talk on “Time” taught us even that could is volatile.

    Most people upload to YouTube or similar, what if YouTube decides to shut down. Unrealistic but..never say never, especially considering the average lifespan of Google services is 4 years .

    Thankfully at the FullFrontal conference, everything was taped and I am looking forward to see those videos on-line very soon, this way I can pass them on to my friends. That will give them a feeling for what they’ve missed out on; hopefully convince them to come with me next year. Many arrive from all over the world and decide to gather up and discuss the fantastic world of Javascript: This year was my first time at FF and I loved it, I will surely go back next year if I manage to get a ticket. And if they run out, I’ll pray for YouTube feeds!

    Addendum: The full audio for the conference is now live for streaming and downloading

  10. Solving Big Startup Problems With Email: The Square Case


    Maybe you didn’t get the news? Oh, I’m sure you did. The creator of Twitter has just launched a service to send money by sending an email.  At Mailjet, we are very excited each time somebody innovates with email. In fact, we believe that Square teaches us an excellent lesson :) Here’s why.

    Email drives innovation but is often neglected

    At  hackathons, developers often go straight to the sexy (and also excellent) Soundcloud and Instagram APIs. Most hackers don’t think an email API has a cool hack potential. But you can be very inventive with email. We try to change this perception.

    Actually, one of our Developer Evangelists recently won a hackathon in Berlin: his hack was an “authorize a payment by email” app. It’s called PayForMe and allows you to buy something without paying it directly. The transaction is effectively approved and executed by a third party, and the validation process is completed by email. Children or employees who want to buy something, but who don’t necessarily have access to a credit card would love this.

    Email is just waiting to be harnessed: the potential is huge.

    What’s really disruptive in this Square Cash story

    This new service is surprisingly intuitive: I send you an email, I cc cash@square.com and there you go. You will receive a confirmation to cash in the money.

    Did you notice? The best innovations always seem to come with the feeling that “how come it didn’t exist before”. Often, it actually did exist before. Square Cash might not be the first to offer a “send money by email” service. But they are different.

    Facebook was not the first social network and Google was not the first search engine. Concepts don’t really matter. The execution is not key either. What matters most is the user experience. From this perspective, it’s the first time ever that you can send money just by sending an email. Literally.

    WYDSIWYG: What you DON’T see is what you get

    The creator of Twitter innovates with email. Ironic? No, iconic.

    Look at Twitter’s concept: 140 characters. Look at Square’s hiring catchphrase: “come simplify the complex.” Simplification turns out to be Dorsey’s number one objective. He knows it’s the real challenge.

    That’s why he says things like: “it”s really complex to make something simple.” I bet he is a fan of Saint-Exupery, who once wrote “perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.” Could be Dorsey’s motto.

    Bottom line is: Square is all about hiding the complexity of a financial transaction. The service’s core user community is composed of coffee shops and organic farms who crave for simplicity. It was therefore logical to use the Simple Mail Transfer Protocol (SMTP…).

    The best thing about this choice? Well, it solves two massive startup problems at once.

    Bypass the change aversion problem

    A friend of mine launched a very cool payment app in France: you can send or receive money by scanning a QR code. The process is very fast, super easy and oversimplified. Still: the users need to change their habits. This is doable but as Dorsey knows “payments are very intimate.”

    Sending money is all about feeling secure. If the user can make a transaction from his everyday email client, the so called “new habit” becomes an obvious one. To ensure the experience is “intimate,” using the pre-existing UI was the best solution.

    Yes, I insist: Square Cash is a product that uses a pre-existing UI.

    Cherry on top: everybody knows how to send an email.  So their “getting started” section is probably one of the shortest ever. Coincidently, this approach allowed Square Cash to even remove the sign-up barrier!

    But this is “only” from the user point of view, these choices are also great for business.

    Solve the chicken and egg problem

    You probably know about network effects: if only one person in the world has a telephone, then telephone is useless because you can’t call anybody. If a few people have this kind of device, then the usefulness is limited. And so on. The more people have a telephone, the greater the value of this communication tool because at some point, you can call anyone.

    Network effects always come with the chicken-egg problem: how do you get your first users, knowing that your tool is almost useless at the beginning? Dorsey is aware of this challenge: he launched Twitter. He solved this paradox once, with a few good tactics and some… luck: a lot of the first Twitter users were actually opinion leaders: either celebrities or journalists. These people are key when you want to fill an empty room. Obviously, the same recipe couldn’t be used for payments.

    Before Square Cash, to send money to someone, you needed that person to install an app, create an account etc. Of course you needed to do the same on your side. The value of the existing solutions increased with the number of people having the app installed and configured. But the hockey-stick growth necessary for these products to really take off simply wasn’t there.

    Email solves this problem as it’s used by everyone. You can send money to anyone who has an email address. No need to wait for them to configure something. Square solved the chicken-egg problem with email.

    Sure, you need to enter your credit card details at some point. But you only do it one time and more importantly: it’s not the first thing you do. I repeat : to send money, you first send an email. Once you get the confirmation, you are already engaged and using the Square Cash product.

    Email: we just need to get it right

    There is always a strong ambivalence in how people perceive email. Jeff Atwood once described it as being “the cockroach of communication mediums: you just can’t kill it.” People love and hate email at the same time.

    This is not rational: email is a medium, it’s not the emails that you receive everyday. Just like TV is not “reality TV shows”.

    Plus, we’re no longer in 1999: anti-spam filters are now ultra-powerful. If you are using a decent service you don’t get overflooded by messages you don’t want. True, the strength of email comes with weaknesses: when something is easy to use, it’s easy to abuse.

    Abusers are either professional spammers or candid senders who don’t know about the rules. At Mailjet, we do a lot to spot the bad guys and educate the senders. We explain how to use email the right way, with the help of APIs and real time feedback loops.

    So yes, 40 year old email still drives innovation

    Once you understood email is a medium, you can leverage it to build great products. Square Cash is an awesome example. But there are some others.

    Look at the blogging platform Posthaven for example: “post by email done right" is key in their value proposition. You send an email to publish a blog post. Isn’t that a smooth way to do this? Your CMS is your email client. People are astonished when they see that email is a key element for their product. Then they think about it and realise how convenient and cool it actually is. Eventually, they wonder why nobody did it before (actually as stated previously, some services were probably doing it before, but they didn’t offer something as simple as this).

    Fun fact is we often face this kind of reaction, even with Mailjet: “who could have thought that delivering email could be the mission of a startup?” We get this a lot. Well, because of these aforementioned elements, now you understand: email drives a lot of powerful startup products. Maintaining an SMTP server often becomes a full time job (anti-spam filters have their downsides), so creating Mailjet made a lot of sense. 

    At Mailjet, we’re pretty sure this Square Cash thing is going to inspire all the hackers at the next hackathons we go to ;)
