Feature List: Development achievements of your secure email service Tuta.

At Tuta, every member of our development team is very passionate about privacy, security and open source. We work on Tuta not just because it is a job, but because it is very fulfilling to work on someting with a meaning: We work on a product that enables everyone to protect their private data and with every new user who joins Tuta, we feel like this is another tiny victory against surveillance capitalism.

We understand that we still have a long way to go until we can fully match the product of surveillance capitalists such as Google or Microsoft, but our development progress in recent years has made great leaps so that we are ready to scale Tuta to new levels!

Best in class security

Here are the most important features that make Tuta's security unrivaled:

• end-to-end encrypted mailbox
• end-to-end encrypted address book
• automatic end-to-end encrypted emails between users
• end-to-end encrypted emails to any email address via a password
• secure password reset that gives us absolutely no access
• full-text search of encrypted data executed locally
• TLS with support of PFS, DMARC, DKIM, DNSSEC, MTA-STS
• GDPR-compliant email service with built-in encryption

Our goal with Tuta is to make security easily accessible to everyone. That's why we strongly focus on usability and convenience. The entire encryption process runs in the background, and you can use Tuta as easily as any email service.

You can use Tuta with absolute certainty that you will never pay with your data.
