Proton Mail vs Tuta Mail

Proton Mail

• People who want an email provider that cannot read their messages
• Anyone moving off Gmail, Outlook or Yahoo who needs to import old mail
• Users who want email, VPN, passwords and storage from one vendor

Tuta Mail

• People who want mail, calendar and contacts encrypted by default
• Using a custom domain with an encrypted mailbox
• Non-profits, schools and open source projects, which get discounts

Proton Mail

• The free plan is limited to 1 address, up to 1 GB of mail storage and 150 sent messages a day.
• Custom domains and IMAP/SMTP access through Bridge need a paid plan.
• The desktop apps need a paid plan; free accounts get a 14-day trial of them, and the Linux app is labeled beta.
• Buying in the iOS app costs more: the US App Store lists Mail Plus at $5.99 monthly, against $4.99 on Proton's site.

Tuta Mail

• The Free plan stops at 1 GB, one calendar and 3 labels, and leaves out inbox rules, offline support and schedule send.
• Free accounts are deleted if you do not log in for more than six months.
• Prices are set in euros. Tuta notes that the final amount can vary with payment platform fees and exchange rates.
• Importing existing mail from EML or MBOX files is limited to Legend and the Unlimited business plan, and works only in the desktop clients.

Proton Mail

End-to-end and zero-access encryption

Messages are encrypted so that only you can read them. Proton states that not even it can read your email.

Tracker blocking and aliases

Blocks the email trackers that report what you open and click. Hide-my-email aliases keep your real address off sign-up forms: 10 on Free and Mail Plus, unlimited on Proton Unlimited.

Custom domains and extra addresses

Mail Plus supports 1 custom email domain and up to 10 addresses. Proton Unlimited raises that to 3 domains and 15 addresses.

Easy Switch import

Imports existing mail from Gmail, Outlook, Yahoo or Apple accounts. The import assistant is included on the free plan.

Proton Mail Bridge

Paid accounts can use the Bridge app to read and send encrypted mail in Microsoft Outlook, Mozilla Thunderbird or Apple Mail over IMAP and SMTP.

Calendar and scheduling tools

Proton Calendar is included, with 3 personal calendars on Free and up to 25 on Mail Plus. Mail also supports scheduled sending, undo send and snooze.

Tuta Mail

End-to-end encryption by default

All data in the mailbox is encrypted so that Tuta has no access to it, and mail between Tuta users is encrypted automatically. Tuta describes its encryption as quantum-safe.

Password-protected emails

Encrypted mail can be exchanged with people who do not use Tuta by agreeing on a shared password with the recipient.

Encrypted calendar and contacts

The calendar and address book are encrypted as well, down to contacts' email addresses and event notifications. Paid plans add calendar sharing and event invites.

Custom domains and extra addresses

The €3 plan includes 3 custom domains and 15 extra addresses, Legend 10 domains and 30 addresses. Paid plans also get catch-all and unlimited custom-domain addresses.

Open-source apps on every platform

The web, Windows, macOS, Linux, Android and iOS clients are published on GitHub under GPLv3, and Tuta runs its own push notification service instead of Google's.

Inbox rules, offline mode, schedule send

Paid plans add unlimited inbox rules, search across the whole mailbox through an encrypted index, offline support, an autoresponder and scheduled sending.
