Tuta Mail

Tutanota enables you to use the benefits of the cloud - availability, flexibility, automatic back-up - without compromising on security. With Tutanota's built-in encryption you own your data, no one else can access it. Tutanota comes with a light & beautiful GUI, dark theme included, with instant push notifications, auto-sync, full-text search, swipe gestures and more.
