Mailjet
European-focused, GDPR-friendly all-in-one.
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.
The question here is which one a backend engineer would rather operate. That means SDK depth in the language already in use, whether a retry can safely be replayed, how much the event log tells you when a customer says the email never arrived, and whether the pricing curve stays sane as volume grows.
Against password resets, receipts, and magic links shipped from application code, Mailjet covers developer experience, SDK breadth, event stream, and webhook coverage, and does not cover idempotency keys. Whether that gap matters depends on how central those are to the build.
