Proton Mail

Proton AG

Proton Mail encrypts your mailbox with zero-access encryption, meaning Proton cannot read your stored messages, and offers end-to-end encryption between Proton users and to others via password-protected messages. Its apps are open source and it operates under Swiss privacy law.

Strengths

✓Zero-access encryption — Proton cannot read your stored inbox
✓End-to-end encryption between Proton users and via protected messages
✓Open-source apps, operated under Swiss privacy law

Caveats

!Mail to non-Proton users isn’t end-to-end unless you use password protection
!Free tier has storage and feature limits

Tuta (Tutanota)

Tuta Mail (Germany)

Tuta (formerly Tutanota) end-to-end encrypts your mailbox — including subject lines and address book — so the provider cannot read it. It is open source and operates under German and EU privacy law, with encrypted messages to non-users via a password.

Strengths

✓Encrypts the whole mailbox including subject lines and contacts
✓Open source and operated under German/EU privacy law
✓Password-protected encrypted messages to non-users

Caveats

!Does not support standard IMAP/POP (uses its own encrypted clients)
!Free tier has storage and feature limits

Gmail

Google

Gmail encrypts mail in transit (where supported) and at rest on Google’s servers, but it is not end-to-end encrypted, so Google can access message content. It integrates deeply with Google’s services and account.

Strengths

✓Reliable, huge storage and deep integration with Google apps
✓Strong spam filtering and account security options

Caveats

!Not end-to-end encrypted — Google can access message content
!Tied to your Google account and ecosystem
!Closed source

Frequently asked questions

Can Proton Mail read my emails?

No. Proton Mail uses zero-access encryption on your stored mailbox, so Proton itself cannot read your stored messages.

What does Tuta encrypt?

Tuta end-to-end encrypts your entire mailbox — message bodies, subject lines and your contacts — so the provider cannot read them.

Is Gmail end-to-end encrypted?

No. Gmail encrypts mail in transit and at rest but not end-to-end, so Google can technically access your message content. Encrypted providers like Proton Mail or Tuta keep the provider out.
