What it is
A self-hosted newsletter and mailing-list manager that ships as a single Go binary and keeps everything in PostgreSQL. Subscribers, segments, templates, campaigns, bounces and per-campaign analytics all live in one admin screen.
What it is good for. Every signup, every trial, every viewer who clicks the link in a video description either lands somewhere or evaporates. A list is the only channel where you decide when people hear from you — no algorithm in between. It is also the cheapest possible launch: 800 addresses beats 800 views, every time. And because it is one binary talking to a PostgreSQL that is already running, it is the lowest-maintenance thing on this page.
- Single binary plus your existing Postgres — no new runtime to learn or patch
- SQL segmentation: "everyone who opened the launch mail but never signed up" is one query
- Genuinely mature — years of steady releases and a large install base
- It does not send mail. You still need SES or Postmark, and you now own deliverability, SPF and DKIM
- AGPL — fine for your own use, but read it before exposing a modified copy as a service
- The editor is functional, not friendly. No drag-and-drop email designer
