Proton Mail vs Tutanota in 2026
Disclosure: SpeedTestHQ is reader-supported. We may earn a commission from purchases made through links on this page. Last updated May 2026.
Both are end-to-end encrypted email services from privacy-focused jurisdictions (Proton in Switzerland, Tuta in Germany). Both encrypt your mailbox so the provider can't read it. The differences are in jurisdiction philosophy, ecosystem breadth, encryption approach, and price.
At-a-glance comparison
| Feature | Proton Mail | Tuta (Tutanota) | Winner |
|---|---|---|---|
| Jurisdiction | Switzerland | Germany | Both strong privacy laws |
| End-to-end encryption (E2EE) | Body of mail; metadata not encrypted at rest | Body + subject + attachments; calendar; contacts | Tuta (broader) |
| Encryption protocol | OpenPGP (interoperable) | Custom (AES + RSA; later post-quantum) | Proton (standards-based) |
| PGP with external recipients | Yes, native | Limited (uses Tuta-side encryption only) | Proton |
| Free tier | 1GB, 1 address, 150 messages/day | 1GB, 1 address | Roughly tied |
| Lowest paid tier | ~$5/month (Mail Plus) | ~$3/month (Revolutionary) | Tuta |
| Custom domain | Paid tiers | Paid tiers (very cheap) | Tuta (price) |
| Number of aliases | Many on paid; SimpleLogin integration | Many on paid | Proton (SimpleLogin) |
| Calendar (encrypted) | Yes (Proton Calendar) | Yes (Tuta Calendar) | Tie |
| Contacts (encrypted) | Yes | Yes (more thorough) | Tuta |
| VPN included | Yes (in Unlimited plan) | No | Proton |
| Cloud drive | Yes (Proton Drive) | No (Tuta Drive announced) | Proton |
| Password manager | Yes (Proton Pass) | No | Proton |
| IMAP / POP / SMTP | Via Proton Mail Bridge (paid) | No (clients only) | Proton |
| Open source | Clients yes; server partial | Clients yes; server yes | Tuta |
| Mobile apps | iOS + Android, polished | iOS + Android, functional | Proton (polish) |
The encryption-model difference
Proton Mail uses OpenPGP. Your mailbox is encrypted at rest with your password (which derives an encryption key the server doesn't have). Mail body is encrypted. Headers and subjects are not end-to-end encrypted because they're needed for IMAP semantics and standards compliance. Mail between Proton users is fully E2EE; mail with external users uses PGP if both sides support it, or password-protected web links as a fallback.
Tuta uses a custom encryption scheme covering more of the surface: body, subject, attachments, calendar events, contacts. Headers are partially encrypted. The trade-off: it's not standards-based, so it doesn't interop with PGP. Mail with external users is only fully encrypted if you send via Tuta's "password-protected mail" feature.
If "the maximum amount of data encrypted on the server" matters, Tuta wins. If "interop with the broader PGP ecosystem" matters, Proton wins.
Ecosystem breadth
Proton offers a full privacy-suite: Mail, Calendar, Drive, VPN, Pass, and a unified account. For users who want a one-stop "leave Google" pivot, this is decisive. The Unlimited plan (~$10/month) bundles everything.
Tuta is more focused — mail and calendar with announced expansion. If you only want encrypted email, the focused product is cheaper and less feature-bloated.
IMAP / SMTP access
Proton Mail can be used with desktop clients (Apple Mail, Thunderbird, Outlook) via the Proton Mail Bridge — a small app that decrypts mail locally and exposes IMAP/SMTP to your client. Paid tier required.
Tuta does not support IMAP/SMTP. You can only use Tuta via its official clients (web, mobile, desktop). This is deliberate — exposing IMAP would require decrypting on the server. Trade-off: zero flexibility for "use your own client."
Migration from Gmail
Both have Easy-Switch-style tools that import existing mail and contacts. Proton's tool is more polished and supports more sources (Gmail, Outlook, Yahoo, IMAP). Plan a few hours for a multi-year archive.
Pricing in real numbers
- Proton Mail Plus ~$5/month: 15GB, 10 addresses, custom domain, unlimited folders/labels.
- Proton Unlimited ~$10/month: 500GB, Mail + VPN + Drive + Pass.
- Tuta Revolutionary ~$3/month: 20GB, 5 aliases, custom domain, calendar, contacts.
- Tuta Legend ~$8/month: 500GB, 30 aliases, more domains.
Tuta is generally cheaper for equivalent storage. Proton's higher tier includes adjacent products (VPN, Pass) that change the price comparison.
Custom domains
Both support custom domains on paid tiers — essential for owning your identity long-term (your email lives at you@your-domain.com regardless of provider). Tuta is cheaper for this; both work well.
Privacy posture and jurisdiction
Switzerland (Proton) has strong privacy and bank-secrecy-style traditions plus the Federal Data Protection Act. Germany (Tuta) has GDPR plus strong privacy law of its own. Both have refused or pushed back on government data requests. Neither will protect you from a targeted, lawful order — but both protect you from mass surveillance and data-mining business models.
Which to pick
| Scenario | Pick |
|---|---|
| Want full privacy suite (Mail + VPN + Drive) | Proton |
| Want maximum encryption coverage | Tuta |
| Need PGP interop with other PGP users | Proton |
| Want IMAP / desktop client support | Proton (via Bridge) |
| Cheapest paid tier with custom domain | Tuta |
| Want everything open-source | Tuta (more open) |
| Already use a VPN you trust | Tuta (don't pay for Proton VPN you won't use) |
| Mobile app polish matters | Proton |
| Activist / journalist threat model | Tuta (broader encryption) or Proton (PGP) |
| Family or small team | Proton Family or Tuta multi-user |
Alternatives worth knowing
- Fastmail — excellent paid email, polished, in Australia. Not E2EE in the same way (server can read mail); great for "stop letting Google data-mine me" without full crypto.
- Posteo — German green-power-funded email, lots of privacy features, no encrypted-mailbox model.
- StartMail — Netherlands-based, PGP-friendly, smaller community.
- Mailbox.org — German, decent PGP integration, IMAP-friendly.
Frequently Asked Questions
Is Tuta really more secure than Proton?
In terms of what's encrypted on the server, yes — Tuta encrypts more (subjects, calendar, contacts). In terms of standards-based interop, Proton wins (OpenPGP). For most users, both are dramatically more private than mainstream email. The "more secure" framing is about which threat model matters to you.
Can I use Proton with Apple Mail or Thunderbird?
Yes, via Proton Mail Bridge (a small local app that decrypts mail and exposes IMAP/SMTP to your client). Paid tier required.
Can I use Tuta with Apple Mail or Thunderbird?
No. Tuta only supports its own clients — deliberately, to keep all decryption client-side.
Does either include a VPN?
Proton Unlimited includes Proton VPN. Tuta does not include a VPN. If you want a VPN bundled, Proton is the simpler choice.
Can I keep my Gmail address?
Forwarding to your new address works, but the identity is still at Google. Best practice: use a custom domain on your new provider so the address is portable. Both Proton and Tuta support this on paid tiers.
Are they GDPR-compliant for business use?
Yes — both are heavily used by EU businesses for GDPR-friendly email. Both have business plans with admin features.
