Proton Mail encrypts messages at rest and supports end-to-end encryption between Proton users, with a Swiss legal jurisdiction that has historically resisted disclosure requests. It includes a calendar and a drive. The free tier gives a usable mailbox with a Proton address.
Who it is for
A journalist or lawyer who needs mail that a provider cannot read or hand over.
Key features
- End-to-end encryption between Proton users

Where it falls short
End-to-end encryption does not protect mail sent to or from non-Proton addresses, and free-tier storage is small.
Pricing
Free tier gives a working mailbox with 1 GB and limited messages per day; paid plans start around $4 a month, and custom domains plus the Bridge are gates.
Prices move; the tier structure is the part that stays true. Check current pricing on Proton Mail.
