git clone https://github.com/marclou/mailcheap.git
Open-source newsletter app where you pay per email sent rather than for dormant subscribers, self-hostable or available as a hosted service.
Why you might care
Aimed at creators who want beehiiv or Substack-style newsletters at a lower cost, since billing is per email sent instead of per subscriber. Self-host with your own Amazon SES or PostShiba account, or use MailCheap Cloud, which runs the same code. Includes imports from beehiiv, Substack, Mailchimp and others, plus an MCP server and REST API so AI agents can write and send issues.
