Postal

Self-hosted email delivery platform for transactional and bulk emails with full control.

PlatformWebfreeglobal

A self-hosted email delivery platform for sending transactional and bulk messages that gives teams control over their sending infrastructure and helps avoid per-message API costs. It is aimed at developers, businesses, and self-hosters who need SMTP-level control and prefer running their own software rather than using a no-code campaign tool.
