Listmonk
listmonk.app
Self-hosted, high-performance newsletter and mailing list manager — send bulk campaigns and manage subscribers without per-contact SaaS fees.
Why it is useful
Listmonk is a single static Go binary backed by Postgres, so it's simple to self-host and handles millions of subscribers efficiently. It includes campaign analytics, list segmentation, double opt-in, and a built-in SMTP-agnostic sender, covering the core of what paid email marketing platforms charge monthly per-subscriber fees for.
