Tuta sells encrypted email and calendar services that keep people's messages and schedules private.
Tuta is a German software company that makes email and calendar apps with encryption built in. When you send a message through Tuta, it gets scrambled on your own device before it ever leaves, and only the person you're writing to can unscramble it. That means even Tuta itself cannot read your mail or peek at your calendar. People use it as a private alternative to Gmail or Outlook, mainly because those big free services scan and store your data to sell ads.
The company was founded in 2011 by a small group of developers in Hanover, Germany, originally under the name Tutanota. In 2024 it rebranded to Tuta. The founders' pitch was simple: privacy should not be a premium feature. They built the whole service around end-to-end encryption and even publish their source code so outsiders can check the security claims. That transparency helps them win trust in a market full of vague privacy promises. Tuta sells to three kinds of customers. Regular individuals pay a few euros a month for extra storage, custom domains, and more aliases. Businesses and organizations pay per seat to move their whole team onto encrypted mail, which matters a lot for law firms, doctors, journalists, and anyone handling sensitive information. The free tier exists to pull people in, and paid subscriptions are the actual business. Competitors include Microsoft with its business email suite and Alphabet with Gmail, plus privacy-focused rivals like Proton.
What makes Tuta interesting is the tension it lives in. Encryption that even the company can't break is great for users but annoying for features — you can't easily search encrypted mail or plug in third-party tools. And regulators in some countries, including parts of the EU, have pushed for ways to scan messages for illegal content, which directly clashes with Tuta's model. The company has been vocal in fighting those proposals. It stays private and doesn't disclose detailed financials, so the outside view is mostly about its growing user base and its stubborn bet that enough people will pay for privacy.
