Your AI agent can now run your newsletter, and you only pay for the emails you actually send. MailCheap is Marc Lou's open-source newsletter app, a cheaper alternative to beehiiv: → Claude, ChatGPT and Grok Bot connect to it through MCP, and Claude Code, Codex and Cursor through an API key → Agents can write, review and schedule issues. Sending always asks you first. → Imports your subscribers from beehiiv, Substack, Mailchimp, Kit and more → Every issue gets its own web page that search engines can find Self-host it with Amazon SES, or use the hosted version, which runs the same code. http://github.com/marclou/mailcheap
