What is it?

Matcha is an email client that runs entirely in the terminal, so you can read, write and send email without leaving the command line. It is built with Go and the Bubble Tea TUI framework and supports multiple accounts and rich message content.

The project includes a plugin system with a built-in marketplace, where plugins can be browsed in the TUI and installed with a single command. Global logging flags control verbosity for the main command and subcommands, including a daemon mode.

On macOS, an optional menu bar helper shows the unread count, sends native notifications for new mail and lists accounts so you can open Matcha in a terminal. The helper connects to the Matcha daemon and is built with the Xcode Command Line Tools.
