Proton Mail

Proton Mail suits people who want a conventional inbox with stronger privacy controls. Folders, labels, categories and subscription management help organize daily mail, while import tools reduce the work of bringing older messages across. Paid plans add custom domains and more room for a growing mailbox.

Encryption has a specific scope: messages between Proton users, or sent using password protection, can be end-to-end encrypted. Ordinary email sent to another provider does not automatically gain that protection. The desktop app is another buying distinction: free users get a trial, then need a paid plan to continue using it.
