Listmonk

Listmonk is a single-binary, high-performance newsletter manager written in Go. Bring your own SMTP. Excellent for technical operators who want full control.

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, Listmonk covers developer experience, scheduling, and webhook coverage, and does not cover SDK breadth. Whether that gap matters depends on how central those are to the build.
