What it is

Tuta Mail is an encrypted email and calendar service from Tutao GmbH in Hanover, Germany. It uses a zero-knowledge architecture with quantum-resistant encryption and, unlike most rivals, encrypts subject lines along with message bodies, attachments, calendars and contacts. All data sits on Tuta’s own servers in ISO 27001 certified data centres in Germany under GDPR.

The web, desktop, Android and iOS clients are open source on GitHub. Tuta does not use PGP but its own implementation, initially based on AES 256 and RSA 2048, and it says forward secrecy is planned for the future. Because decrypted data never leaves the client, Tuta does not offer IMAP at all.

What it costs in practice

The free plan gives 1 GB, one calendar and 3 labels, with no extra addresses, custom domains or support. It is limited to one account per person for private use, and Tutao may terminate a free account without notice if it goes unused for six months. Revolutionary is €3/mo paid yearly (saving €7.20) or €3.60/mo monthly, tax included, and brings 20 GB, 15 extra addresses and 3 custom domains.

Legend is €8/mo yearly or €9.60/mo monthly for 500 GB, 30 addresses and 10 domains. Business plans are €6, €8 and €12 per user per month on yearly billing, excluding tax, with monthly rates of €7.20, €9.60 and €14.40. Plans renew automatically at the end of the chosen period; no separate renewal price is printed. There is no money-back guarantee beyond the 14-day consumer right of withdrawal in the terms.

Frequently asked questions

How much does Tuta Mail cost?

There is a free plan with 1 GB. Revolutionary is €3/mo paid yearly or €3.60/mo monthly, tax included. Legend is €8/mo yearly or €9.60/mo monthly. Business plans run from €6 to €12 per user per month on yearly billing, excluding tax.

Is there a money-back guarantee?

None is stated on the pricing pages. The terms give consumers a 14-day right of withdrawal and refund prepaid fees if Tutao ends a contract early. Subscriptions renew automatically at the end of the chosen period and no different renewal price is shown.

Verdict

Tuta Mail is the cheapest paid encrypted mailbox here, and it encrypts subject lines where Proton does not. The trade-off is technical isolation: no IMAP, no PGP, and no independent audit cited, so you take the open-source code on trust. Choose it for price and full-message encryption; look elsewhere if you need a desktop client of your own choosing.
