Email for humans
and machines.

A desktop email client with a CLI and MCP server. AI-powered, privacy-first, completely free and open source.

Why Maho Mail

Email clients made
you choose.

GUI or terminal. Pretty or programmable. Manual or automated. Every email client picks a side. Maho Mail gives you all three — a desktop app, a CLI, and an MCP server — sharing one local database.
