Self-hosted newsletter and mailing-list manager, a single small program with a web dashboard.

Why it’s listed

It's free and AGPL open source, with 23,000+ GitHub stars and a release in June 2026 (1,2). It's light: a 7 million email campaign peaked at 57 MB of RAM, by its own test (1). Its site carries no analytics scripts.

The trade-off

You need your own server and an outgoing mail service (SMTP), so it's a project, not a sign-up.

Price

Free software; you pay for your server and email sending.
