ProtonMail vs Tutanota (Tuta): Honest 2026 Comparison

Two things most comparison lists get wrong before you even start: Tutanota is now called Tuta, and "which is more secure" has a real-world answer involving a 2021 police case. Here's the comparison updated for 2026, with verified Android ratings and no affiliate spin.

The Rebrand: Tutanota = Tuta

Tutanota rebranded to Tuta ("secure message" in Latin). Same company, same encryption, same apps — new name. On the Play Store you'll find it as Tuta Mail. Older articles saying "Tutanota" are talking about the same service.

How Encrypted Email Actually Works (Simple Version)

Normal email is like a postcard — anyone handling it can read it. Encrypted email is like a locked box: only the sender and recipient have the key. With ProtonMail and Tuta, that box is locked on your device before it ever travels the internet, and the companies genuinely cannot open it — this is called zero-access encryption. The catch: it only works fully when both people use the same service. Email to a Gmail address travels mostly unencrypted (that's how email works everywhere), though both services let you add a password lock that any recipient can open with the password you share separately.

Quick Comparison

The Real Security Difference

Both use end-to-end encryption with zero-access architecture — neither company can read your email bodies. The differences that actually matter:

• Subject lines: Tuta encrypts them; ProtonMail doesn't (a standard email limitation, but Gmail-style scanning of subjects is still possible).
• Interoperability: ProtonMail speaks PGP, so you can exchange encrypted mail with non-Proton PGP users. Tuta's custom protocol only encrypts fully inside Tuta.
• Quantum resistance: Tuta advertises quantum-safe cryptography; ProtonMail's PGP stack is the battle-tested standard.
• Outside email: Both let you send password-protected emails to anyone — the recipient opens a link and enters the password you shared separately.

The 2021 Incident You Should Know

In September 2021, French authorities working with the Swiss government were investigating activists on theft charges. ProtonMail, under a Swiss court order, handed over the activists' IP addresses. Proton's policy: no permanent IP logs, but temporary IP retention for anti-abuse, and Swiss law can compel logging in criminal investigations. Tuta's policy is stricter on paper: it strips IPs from emails and only logs under a German court order for serious crimes — with no public case of it happening so far. Neither service can read your encrypted email content. But if your threat model includes law enforcement, this incident is the single most relevant fact, and most listicles bury it.

Free Plans Compared Honestly

Both offer free tiers, and this is where most people start — so let's be precise about the limits:

• ProtonMail free: roughly 500MB–1GB of storage (the exact figure has changed over the years — check the current pricing page), a daily sending limit (around 150 messages/day), and limited folders/labels. Enough for a secondary private address.
• Tuta free: 1GB of storage, no daily sending limit, unlimited folders — but only Tuta email domains (no custom domain) and no direct customer support.

Tuta's free plan is objectively more generous. Proton's free plan exists mainly as a trial of the ecosystem. If you never plan to pay, Tuta gives you more room to breathe.

What Neither Service Protects You From

Honest security talk requires the other half of the story:

• Your own device. If your phone has spyware, encryption doesn't help — the attacker reads the screen, not the email.
• Metadata. Who you email, when, and how often is visible to varying degrees. Tuta encrypts more of it than Proton, but the fact of communication isn't fully hideable.
• Phishing. No encryption stops you from typing your password into a fake login page. Proton's PhishGuard helps; your own caution helps more.
• The other end. Your encrypted email is only as safe as the recipient's device and habits.

Migrating: Which Is Easier?

ProtonMail wins migration clearly. Its Easy Switch tool imports messages, calendars, and contacts from Gmail, Outlook, Yahoo, iCloud, and AOL in a few taps — no manual exporting. Tuta's migration is more manual: you can import mailboxes via its desktop clients, but reviewers consistently call it less smooth. If you're moving years of Gmail history, this alone may decide for you.

ProtonMail's Strengths

• PGP compatibility. Encrypted mail with any PGP user, not just Proton users — the biggest functional advantage.
• Desktop email clients. Proton Bridge (paid) lets Thunderbird, Outlook, and Apple Mail work with your encrypted inbox.
• Bigger ecosystem. Proton VPN, Drive, Calendar, and Pass bundle into higher tiers — one account, one bill.
• Easier migration. Easy Switch imports from Gmail/Outlook/Yahoo in a few taps; hide-my-email aliases protect your real address.
• Swiss jurisdiction. Outside the EU and the 5/9/14 Eyes alliances — though note the secondary US offices.

ProtonMail's Weaknesses

• More expensive. Paid starts ~€4/month with less storage per tier than Tuta.
• Free tier limits. Sending limits per day and limited folders/labels on free.
• Subject lines unencrypted. Metadata exposure remains.
• Bridge is paid. Desktop-client access requires a subscription.

Tuta's Strengths

• Cheaper at every tier. ~€3/month paid start, 20GB on the entry plan, and the free plan has no daily sending limit.
• Encrypts everything. Subjects, contacts, calendar — the full mailbox, not just bodies.
• Desktop apps. Native clients for Windows and Mac, with Linux in beta — Proton ships them too now.
• F-Droid availability. Install without Google services — a real plus for de-Googled Android users.
• Privacy hygiene. Built its own reCAPTCHA alternative instead of sending data to Google; no tracking.

Tuta's Weaknesses

• No IMAP/SMTP, no PGP. You're locked into Tuta's apps — no Thunderbird, no Outlook, no encrypted mail with PGP users.
• German jurisdiction. Inside the EU and the 14 Eyes intelligence-sharing alliance.
• Smaller ecosystem. Email + calendar + contacts is the whole product; no VPN, no drive.
• Support for free users. Community only — paying subscribers get direct support.

Android Notes (Verified)

Both apps are on the Play Store with strong ratings: Proton Mail 4.49 (94,777 reviews) and Tuta Mail 4.37 (18,587 reviews) — verified live today. Proton Mail on Google Play and Tuta Mail on Google Play. Tuta also publishes on F-Droid if you run a de-Googled phone.

Who Should Pick Which

• Choose ProtonMail if you need PGP interoperability, want desktop email clients via Bridge, prefer Swiss jurisdiction, or want the VPN/Drive bundle.
• Choose Tuta if budget matters, you want subject-line encryption, you use Linux or want F-Droid, or you just want the cheapest fully-encrypted mailbox.
• Neither if your contacts all use Gmail — encrypted email only protects mail between users of the same service. For password-based protection of your accounts generally, see our guide to authenticator apps.

The Ecosystem Question

This is really two different products wearing the same category label. ProtonMail is the gateway to an ecosystem: start with email, add VPN for public Wi-Fi, Drive for files, Pass for passwords — all under one privacy-respecting account. If you want to de-Google your whole digital life, Proton is the one-stop shop. Tuta is the focused tool: email, calendar, and contacts done with maximum encryption at minimum price. It will never sell you a VPN. Pick based on whether you want a suite or a scalpel — most reviewers who crown a "winner" are really just revealing which of those two they personally prefer.

Quick Decision Checklist

Frequently Asked Questions

Is Tutanota now called Tuta?

Yes — Tutanota rebranded to Tuta. The service, apps, and encryption are the same; only the name changed.

Is ProtonMail safer than Tutanota?

Both are highly secure with end-to-end encryption. Tutanota encrypts subject lines (ProtonMail doesn't); ProtonMail supports PGP for communicating with other encrypted-email users. Jurisdiction differs: Switzerland vs Germany.

Which is cheaper, ProtonMail or Tutanota?

Tutanota (Tuta) is cheaper: paid plans start around €3/month vs ProtonMail's €4/month, with more storage per tier. Tuta's free plan also has no daily sending limit.

Did ProtonMail give user data to authorities?
