Proton Mail: Email chiffré

Proton Mail: Email chiffré is the privacy-first email service people reach for when ordinary inboxes feel too exposed. By our assessment, its real strength is end-to-end encrypted mail inside the Proton ecosystem, plus a reputation built around privacy rather than advertising. The downside is familiar to anyone using secure mail: it can be less convenient when the other side is outside Proton, and some of the sharpest privacy features sit behind the paid plans. In practice it feels like a normal mailbox with extra locks, which is exactly the point. Compared with Gmail or Outlook, it is less about integration and more about keeping correspondence private. It suits people who put confidentiality ahead of convenience, and it is less appealing if the main goal is a big office suite around email.
