Pros
If you want to experience and be a part of building a successful international tech company in a super competitive space with great coworkers, Mailjet is the place to be. Credit to the Mgmt team and especially all of my former colleagues in building Mailjet from a local regional email service provider into a formidable international competitor and producing leading edge email innovations along the way (Passport, Real Time Monitoring, etc.). Further kudos for also building a diverse workforce in every sense of the term... Women <> Men parity and not just at the employee level but also leadership level. Multiple nationalities, cultures, languages. You'd be hard pressed to find as much diversity in any tech company the size of Mailjet! Lest I forget, the weekly sport and yoga classes offered by the company were always a great break from work and very appreciated.
Cons
If you are into structured processes, spending weeks or months on strategy analysis, enjoy well defined static KPIs, etc., Mailjet is extremely challenging. If you appreciate thinking on your feet, creative problem solving, digging in and contributing on an operational level no matter your seniority, going up against competitors 5x your size, this is the place for you.
