Gives every service its own email alias so you can cut one off without moving
proton.me
Encrypted mailbox where the provider cannot read the contents of your messages.
Mail is stored encrypted with a key derived from your password, so Proton can serve your inbox without being able to read it, and messages between Proton accounts are end-to-end encrypted automatically. Swiss jurisdiction and an open-source client are the other half of the pitch. Mail to the rest of the world is ordinary email unless you set a password on it or exchange PGP keys.
Questions
A genuinely usable free tier with paid plans for volume or team features. Free gives one address, 1 GB of storage and 150 messages a day, and mail to non-Proton users is only encrypted if you take an extra step.
Yes. Proton Mail sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
