Tutanota – the open source end-to-end encrypted email app.
The open source app Tutanota enables you to send end-to-end encrypted emails to anybody with a tip of your finger. Even emails that are being sent without end-to-end encryption and all your contacts are stored encrypted on the Tutanota servers.
Only you with your password have access to your encrypted data, profiling is impossible. Tutanota combines security with ease-of-use so that everybody can use end-to-end encryption. Now you can take back your privacy easily!
- Register your free Tutanota account with 1 GB of free storage.
- Choose your email address from the supported domains @tutanota.com, @tutanota.de, @tutamail.com, @tuta.io and @keemail.me.
- Send and receive end-to-end encrypted emails to anybody, to other Tutanota users automatically and to external users secured with a password.
- Send and receive old-fashioned emails (not end-to-end encrypted). Even these emails are stored encrypted on the Tutanota servers.
- Subject, content and attachments are automatically encrypted.
- Supports push notifications when receiving new emails.
- Auto-complete contact names as you type from your Tutanota or your phone contacts.
- Tutanota is open source so that anyone can verify its security by auditing the code.
The Tutanota app asks for very few permissions to keep your level of privacy to a maximum:
- Full network access: Used to send and receive emails.
- Receive data from the internet: To notify you when you receive a new email.

Ratings and Reviews
Good, but could be better
The iOS client is still using its old, slow version, but that is still in beta, so it’s understandable. That said, in both versions, it’s way too difficult to mark senders/domains as spam. The best version requires you to copy the sender/domain, click Settings, click Global Settings, click “Show” next to Spam rules, click the “+” symbol, paste the user/domain, click the pencil, changing it fro “No spam” to “Always Spam” or “Discard,” and then clicking “OK.” That is an unacceptable amount of steps for what should be a very simple task.
Also, despite being on the iPhone for more than three years, there is still no TouchID, meaning that if your phone is unlocked, either you have to enter in what should be a complex password every time you open the app, OR just forgo additional security entirely.
The longer these issues persist, the more tempted I am to experiment with Protonmail, as I know through a friend that both of these issues are addressed. Tutanota Premium is significantly cheaper at 1€ per month, versus Protonmail’s 4€ per month, but that will only get one so far before the long-lived problems just aren’t worth the savings.
Thanks for your feedback. 2FA is coming with our new client. We'll also improve speed & design with our new client (currently in private beta). You can vote for any missing feature here: https://tutanota.uservoice.com/
Service needs desktop app w/ offline mode
This is a great open source end to end encrypted email service for those that care about privacy. However it's easy enough for anyone that just wants assurance that no third party is reading or logging the content of their emails to use. Everyone should care about privacy unless they want to end up living in a world where powerful companies and governments know everything about us and potentially use that knowledge and power to limit our freedoms. With that said, the only thing keeping me from switching to this service as my primary and only email provider is the lack of a desktop app that allows me to download my emails to my PC and have the app keep them securely encrypted but accessible on my PC with the ability to export some or all of the emails to a format that can be imported by popular mail clients like Outlook or Thunderbird should I ever need to do so. I really hope the developers create a Tutanota desktop app with offline encrypted email storage and export capability. If they do I'm switching email providers tomorrow.
Offline apps are planned, they will need a little time, though. Please vote for missing features here to speed up development: https://tutanota.uservoice.com/
Could be just a little faster
Tutanota as a service is great, and after correcting the server flaws which caused the app to freeze it's quite pleasant to use in the iPhone.
Still, it could be just a little faster when updating the inbox and showing mail. It's not an unbearable speed tough.
Also the default option of blocking images could be adapted so that trusted contacts would dismiss the need for constantly allowing pictures. On low quality networks (mostly nearly out of wifi range) this actually ends up preventing the download of images even after the button is pressed, and the program must be reopened to fix it.
Thanks for your feedback. The freezes were caused by a server error, which we fixed within a couple of days. Are you still experiencing issues with the app?
