About Tuta
Tuta (renamed from Tutanota in 2023) is an encrypted email and calendar service run from Germany. It encrypts more of your mailbox than most rivals, including subject lines, contacts and calendar entries, and it uses post-quantum cryptography for new accounts. Its apps are open source and available for the web, Windows, Mac, Linux, iOS and Android. A free plan gives a single address with limited storage; paid personal plans add custom domains, more storage and aliases, and there are business plans priced per user. Tuta deliberately does not support IMAP, because that would expose mail unencrypted to other clients, so you must use its own apps. That keeps the security model tight but rules out Apple Mail, Outlook or Thunderbird. Search, filtering and import tools are simpler than mainstream services, and free accounts must be used regularly to stay active. It is a good fit for people who want maximum encryption at a low price.
Best for: People who want the most encryption for the least money and accept using Tuta's own apps.
