Ghostmail

macOS

A quiet, private email client that lives in your Mac’s menu bar. The icon appears when you have unread mail and vanishes when your inbox is clear.

Lives in the menu bar

Unread counts and a floating panel to read, reply, and compose — always a click away. No Dock icon, no distractions.

Private by design

Credentials are encrypted on your Mac with AES-256-GCM. Matter ApS runs no servers and never sees your mail.

Works with your accounts

Gmail and Outlook via secure OAuth 2.0, plus any standard IMAP / SMTP host. Multiple accounts supported.

Smart alerts, optional

An opt-in AI classifier can flag what matters — using your own API key. Off by default.
