LetterSpace

Open-source, self-hosted newsletter platform for managing subscribers and sending campaigns

Webfreeglobal

LetterSpace is an open-source, self-hosted web app for managing subscribers and sending newsletter campaigns, aimed at independent writers who prefer to control their mailing lists rather than use hosted services. It provides the core tools for list management and campaign delivery and is intended for those willing to self-host rather than seek a fully managed platform.
