MailerSend

MailerSend was built by the same team behind MailerLite, focused on transactional. Drag-and-drop templates plus a code-first API cover both designer and engineer flows. Pricing is competitive at small to mid volume.

A SaaS product sends on behalf of its customers, so the deciding factors are tenant isolation, whether suppressions can be scoped rather than global, and whether support can answer why one specific account did not receive one specific email. Lifecycle automation and transactional sending usually need to coexist.

Against trial expiry notices, dunning, onboarding sequences, and per-tenant transactional mail, MailerSend covers multi-tenant support, event stream, the suppressions API, scheduling, and webhook coverage, and does not cover operating track record. Whether that gap matters depends on how central those are to the build.
