AGPL-3.0 self-hosted newsletters and transactional mail

What's Good
AGPL-3.0. Campaigns, lists, templates, and transactional API. You run it; there is no vendor meter. Fast Go binary, first-party docs, no seat tax.
The Catch
AGPL-3.0 is copyleft — network use means you share modifications. You operate Postgres, SMTP, and bounces. There is no official hosted Listmonk Cloud.
Verdict
The self-host newsletter stack. AGPL, fully free, you run the mail.
