Which one is for you
Pick AtomicMail if
- Fits if you want an encrypted mailbox with no phone number
- Works for small teams that want custom-domain mail at $3 or $6 a user
Look elsewhere if
- Pricey if you pay monthly, as Plus is $7 against $5 on annual billing
- Tight if you stay free: 10 aliases and no custom domain
- Watch out: the business prices don't say whether they assume annual billing
- Watch out: Atomic GPT and Atomic VPN limits on Plus and Business aren't stated
- Watch out: teams of 100 or more are sent to a contact form
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
| 3.0GPAAtomicMailVery good | 2.8GPATuta MailGood | |
|---|---|---|
| Value for money | AThe free plan has unlimited storage and 10 aliases. Plus is $5 a month billed annually, a little under the middle of what email services charge. | 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 | BA free encrypted mailbox with unlimited storage, 10 aliases and no phone number needed. One person could live on it. | 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 | BEncryption, aliases, Hide My Email, recovery by seed phrase and custom-domain team mail. The listing shows no gap in the job. | 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 a recovery seed phrase and your own aliases, and a lost phrase is yours to deal with. | 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 | BWeb, Windows, macOS, Linux, iPhone and Android apps. No API or integrations are listed. | 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. |

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.
- The differences and the answers to the questions are worked out from those listings.
