Mailjet

Mailjet is an email delivery and marketing platform founded in 2010 in Paris, France, by Wilfried Durand and Julien Tartarin. The company provides both transactional email (API-driven emails like password resets and order confirmations) and marketing email (newsletters, campaigns) through a unified platform. In 2019, Mailjet was acquired by Mailgun (now Sinch Email), but continues to operate as a distinct brand with its European infrastructure intact.

The platform offers a drag-and-drop email editor with real-time collaboration (multiple team members can edit a template simultaneously), an intuitive REST API for transactional email, SMTP relay, advanced segmentation for marketing campaigns, A/B testing, and detailed analytics including deliverability statistics. Mailjet's API supports multiple programming languages and provides webhooks for event tracking such as opens, clicks, and bounces.

Mailjet processes billions of emails annually and serves over 150,000 companies worldwide. The platform is designed with GDPR compliance at its core, with data processing infrastructure located in the EU. It is a practical choice for European businesses that need reliable email infrastructure without sending their communication data to US-only services. The combination of transactional and marketing email in a single platform with competitive pricing has made Mailjet popular among startups and mid-market companies across Europe.
