Tutanota

Tutanota is an end-to-end encrypted email app with an encrypted calendar & encrypted contacts, all in one place. No one but you can access your emails, calendars, or contacts.

More Details

Tutanota is a German-based secure email service. It’s different from services like Gmail in that even though Google encrypts the stored messages on its servers; they still hold the encryption keys. This means they have all the access to your data.
