We take your email needs seriously by offering you a secure email service free from advertisements.

From our clear and minimalist design to whitelabel customizations, from our free version for personal use to our fully-featured secure business email for companies, we are committed to making sure Tutanota is the only email service you will ever need.
We guarantee that your data in Tutanota is always encrypted - whether you use our secure webmail client, our apps for Android and iOS, or our desktop clients for Windows, Linux and Mac OS. Easily send a secure email with the knowledge that Tutanota encrypts subject, body and all attachments for you. Import all your contacts into Tutanota's encrypted address book, and rest assured that nobody else can access your contacts' personal information.
Tutanota comes with an encrypted calendar, free for all users. The calendar is integrated seamlessly into the secure email client and can be easily accessed on any device. Event notifications are sent end-to-end encrypted to fully protect your privacy. We are extending the current calendar so that you will be able to share encrypted calendars, send invitations, and more.
Privacy is a fundamental human right. We are building Tutanota to enable you to send free secure emails to anyone. To fight for our right to privacy - to protect journalists, whistleblowers and human rights activists around the world - this has been our mission since we have started building the free encrypted email service Tutanota, and it is a value shared throughout our community. Support Tutanota and help us to build the Internet of the future: private and secure! Together we will stop mass surveillance with built-in encryption.
