E-Mail | Tuta

Private or Business E-Mail Mailbox

End-to-End Encryption made easy

If you have the highest demands on usability and encryption, you should definitely try Tuta – for free!

Secure Solution for all technical Platforms

E-mails, address book and calendar are stored end-to-end encrypted in Tuta. When logging in, the mailbox is automatically decrypted locally on your device. For your smartphone there are Tuta apps for Android and iOS. And for Windows, Linux and Mac OS there is a desktop client. Otherwise, just use your web browser. Tuta uses symmetrical (AES 128) and asymmetrical encryption (AES 128/RSA 2048) to encrypt e-mails end-to-end.

If sender and recipient use Tuta, all e-mails are automatically encrypted end-to-end (asymmetric encryption). Encrypted e-mails to external recipients are secured by a one-time password exchange (symmetrical).

Easy to use, absolutely fair

The limited free version allows you to try out the service for an unlimited period of time and makes it easier to decide on an annual subscription with all the benefits. With one gigabyte of storage space in the free version, many users will be able to manage permanently.

After personal testing, you will probably be happy to pay 3.00 EUR/month to upgrade to a Revolutionary annual subscription.
Or, if you are a frequent user with high demands like me, you may decide to take the Legend subscription and thus support the development of Tuta with 8.00 EUR/month.

Sceptics choose the monthly subscription instead of an annual subscription and pay 3.60 EUR/month (Revolutionary) or 9.60 EUR (Legend).
I have mentioned prices for private individuals here. A family tariff will be official added soon, but this is already made possible in an uncomplicated way via the service if someone doesn't want to wait.
There are also suitable tariffs for freelancers and companies.

Tuta treats its customers absolutely fairly. Tariff changes are possible at any time and are charged in a customer-friendly way.
When, to celebrate 10 million customers, new tariffs were introduced for a limited period with 50% discount, I, as long-time existing customer, received a 50% discount for switching from Premum tariff to the new Legend tariff, just like new customers: Payment of EUR 96.00 + 12 bonus months!

From Hannover (Germany) for the World

The menu navigation is in the web browser and on the smartphone (apps for Android and iOS) in German and 57 other languages, the website of Tuta is currently available in 33 languages, many of them also in German.

Fully encrypted Calendar

Secure e-mail was the primary goal of Tutao GmbH. For this reason, the calendar was not integrated in a preliminary version until 08.07.2019 (since 10.07.2019 in the Apple App Store). An own cloud storage is also planned. Gradually Tuta will be expanded to an Office Suite.
