Which one is for you
Pick FlowCrypt if
- Fits if you use Gmail and want to send encrypted messages to anyone
- Works for a company under 100 users that wants it free
Look elsewhere if
- Not for you if you use Outlook, as that version is on a waitlist
- Watch out: Workspace Key Manager is priced apart, €799 a year for 10 seats and €899 for 20
- Watch out: Google's client-side encryption needs a Workspace Enterprise Plus, Education Standard or Education Plus licence
- Tight if you're a company over 100 users, as that's sold through sales with no published price
Pick Tuta Mail if
- Fits if you want mail, calendar and contacts encrypted by default
- Works for non-profits and schools, who can apply for 50% off
Look elsewhere if
- Tight if you're staying free, with 1 GB, 3 labels and no inbox rules, offline support or schedule send
- Skip it if you'd only check in now and then, as free accounts are deleted after six months without a login
- Pricey if you want old mail moved in, since EML and MBOX import needs Legend at €8 and a desktop app
- Watch out: prices are in euros, and Tuta says the final amount moves with fees and exchange rates
- Skip it if you want other apps to talk to your mail, as no integrations or API are listed
How we grade them
| 3.0GPAFlowCryptVery good | 2.8GPATuta MailGood | |
|---|---|---|
| Value for money | AFree for companies with under 100 users per domain, with password-protected messages and 25MB attachments. Enterprise is quote-only. | B€3 a month paid yearly sits inside the cheapest quarter of paid email, which starts around $4 against a middle of $8. For that you get 20 GB, 15 extra addresses and 3 custom domains. Prices are in euros, and Tuta says the final amount moves with fees and exchange rates. |
| Free plan and trial | AFree outright for domains under 100 users, with encrypted Gmail, password-protected messages, an encrypted contact page and a mobile app. | CFree includes the same encryption, but the box is 1 GB, one calendar and 3 labels, with no inbox rules, no offline support and no schedule send. A year of attachments will fill that. And the account is deleted if you don't log in for six months. |
| Features | CEncryption inside Gmail, password-protected messages, an encrypted contact page, mobile apps and enterprise administration. It does that job fully, but it's a smaller job, and it covers Gmail only. | CThe mail basics are covered, and the encryption reaches the calendar and address book too, with password-protected mail to people outside Tuta. But the listing names its own gaps: importing old EML or MBOX mail is Legend and Unlimited only, and desktop only, and inbox rules and offline are paid extras. |
| Ease of use | CNo store rating on record. You set up keys, and recipients without FlowCrypt open messages with a password, so there's a learning curve. | A4.72 from about 3,700 App Store ratings, which is the top end of this category. Encryption is on from the first login and mail between Tuta users encrypts itself, so there's nothing to switch on. |
| Platforms and integrations | BA browser extension plus iOS and Android apps, with Gmail, Google Workspace, Auth0 and OneLogin connections. No desktop app. | BWeb, Windows, Mac, Linux, iPhone and Android, with Tuta running its own push service rather than Google's. Every device, then, but the listing has no integrations and no API at all, so nothing else on your computer talks to it. |
| Best for | encryption inside Gmail | encrypted email and calendar from €3 a month |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
