Proton Mail for Business Review
Encrypted business email from the makers of Proton VPN.
Proton Mail for Business puts end-to-end and zero-access encryption on every tier by default, running out of Switzerland with EU privacy law behind it. The entry Mail Essentials plan bundles Mail, Calendar, and Proton VPN under your own domain.
The tradeoff is scope: Proton's full productivity suite (Drive, Docs, Sheets, Meet) only unlocks at the pricier Workspace tiers, and storage on the entry plan is modest next to Google or Microsoft.
