Otter Mail

Gmail, calm and fast. A desktop mail app for macOS.

What it does

Several Gmail accounts side by side, or combined into one inbox.
Gmail labels, plus saved views that filter across accounts.
A local cache with full-text search, so mail opens instantly and works offline.
A menu-bar mini inbox, new-mail notifications and a Dock unread badge.
On-device translation of mail in other languages, using Apple's translator.
Calendar invitations you can answer in place, and one-click unsubscribe.
An optional assistant that works on your mail through your own Claude Code, Codex or Hermes.

Your mail stays on your Mac

Otter Mail talks to Google directly from your computer. There is no Otter Mail server: your messages, contacts and sign-in are never sent to us. Details are in the privacy policy.
