## Kitsmith's 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.

## Features

- **Zero-access encryption:** End-to-end and zero-access encryption means Proton states it cannot read inbox contents on any plan.
- **One-click Gmail import & sync:** Imports existing mail from Gmail, Outlook, Yahoo, or Apple, with ongoing Gmail sync.
- **Hide-my-email aliases:** Generates aliases at signup to reduce spam and make cutting off unwanted senders easier.
- **Open source, independently audited:** Proton’s apps and encryption libraries are open source and have had independent security audits, per the developer.
