Mailjet

Mailjet (Sinch) offers transactional plus marketing with EU data residency. Drag-and-drop builder is among the better ones. API is solid but not differentiated.

At an early stage the deciding factors are what the free tier actually covers, what the first paid invoice looks like, and how much of a founding engineer's week the setup costs. Feature depth that only matters at a million sends a month is noise until it is not.

Against a waitlist, a launch announcement, onboarding email, and the first transactional sends, Mailjet covers every capability this audience leans on: developer experience, scheduling, SDK breadth, and webhook coverage. The deciding factor becomes price and operational preference rather than feature gaps.
