What is Proton Mail?
Proton Mail is an email service focused on privacy and security, offering end-to-end encryption for communications. It is used by individuals and businesses who prioritize keeping their email conversations private and protected from tracking. The service is based in Switzerland, which provides specific privacy law protections. Users can send and receive emails with the assurance that their messages are encrypted from sender to recipient. The service also employs zero-access encryption, meaning even Proton Mail cannot read user emails. It aims to provide an ad-free inbox experience and prevent email trackers from monitoring user activity.
