Meet Tuta

Tuta, formerly Tutanota, is an email service with encrypted calendars and contacts for personal and business use. Messages exchanged between Tuta users are automatically encrypted end to end, including subject lines and attachments. Users can also send protected messages to people on other email services by sharing a password, while ordinary external email remains available.

The service works in a browser and through open-source apps for Android, iOS, Windows, macOS, and Linux. It combines everyday communication tools with spam and tracking protection and optional two-factor authentication. Free accounts provide an ad-free starting point, while paid plans add custom domains, more storage, and offline access. Users can manage correspondence and appointments together without relying on advertising-funded email.
