Unified inbox
Gmail, Outlook, Spacemail, Purelymail, and any IMAP provider in one place.
Open Mailer is a beautiful, unified inbox for Gmail, Microsoft 365, IMAP, and more — with offline cache, OS keychain storage, and no hosted backend required.
A focused email client without ads, tracking, or a cloud middleman reading your mail.
Gmail, Outlook, Spacemail, Purelymail, and any IMAP provider in one place.
Passwords and OAuth tokens never touch our servers — there are no servers.
SQLite cache with full-text search keeps your mail available without a connection.
FTS5-powered search across subjects, senders, and message bodies.
Dark gradients, smooth animations, and a layout that adapts from phone to desktop.
Rust backend, native shell, and a lean React UI — fast sync, fast compose.
