[8] Tuta Mail has recently integrated post-quantum cryptography features through its new protocol - TutaCrypt replacing standard encryption methods like RSA-2048 and AES-256 for its newly created accounts after March 2024.

Their vision gained even more importance, when Edward Snowden revealed NSA's mass surveillance programs like XKeyscore in July 2013.

[15][16] In August 2018, Tuta became the first email service provider to release their app on F-Droid, removing all dependence on proprietary code.

[17][18][non-primary source needed] In November 2020, the Cologne court ordered monitoring of a single Tuta account that had been used for an extortion attempt.

An ex-RCMP officer, Cameron Ortis, testified that the service was used as a storefront to lure criminals in and gain information on those who fell for it.

He stated authorities were monitoring the whole service, feeding it to Five Eyes, which would disperse it back to the RCMP in order to gain more knowledge about the criminal underground.

Tuta Mail is a fully end-to-end encrypted email service available for download on Android (Google, F-Droid, apk) and iOS.

In 2024 Tuta introduced quantum-resistant algorithms in a hybrid protocol similar to Signal to protect the data against future attacks from quantum computers.

[36][37][38][39][40] Tuta also stated that it does not use PGP due to its limitations in encrypting subject lines and lack of flexibility for algorithm updates.

In July 2023, TechRadar praised Tuta Mail as an "Excellent encrypted email platform" focusing on its broad features and intuitive design.

The project, officially named "PQDrive - Development of a Post-Quantum Encrypted Online Storage," is funded by the German government's KMU-innovativ program (€1.5 million), which supports Small and medium-sized enterprises (SMEs) like Tuta.

The project receives further support through a €600,000 collaboration with the University of Wuppertal, which will play a key role in research and development.
