Price checked at source September 18, 2026.
End-to-end encrypted email from Swiss privacy company Proton AG — free tier available, with paid plans bundling calendar, VPN, and storage.
Our take
The pitch is zero-access encryption: Proton states it can’t read your inbox on any plan, paid or free, which is structurally different from ad-funded webmail. Proton AG is majority-owned by the nonprofit Proton Foundation and headquartered in Switzerland, which the company leans on for stricter privacy-law backing. The free plan is genuinely usable (1 GB storage, 1 address); paid plans layer in more storage, custom domains, and bundle Proton’s VPN, Drive, and password manager rather than selling email alone.
