Plainmail

Plainmail is a simple but efficient macOS email client. It features a very clean, if throwback, interface, while using the default macOS UI/UX and features.

Plainmail works on Apple silicon only (M-series chips).
Plainmail is macOS only. No version for iOS is planned.
Plainmail connects directly to your mail provider. Your mail is stored only on your Mac, encrypted, and is never sent to us or to anyone else.
Plainmail is offered “as is”, with no support or guarantee of future versions.
