ProtonMail
FreemiumEnd-to-end encrypted email service based in Switzerland offering secure email, calendar, and drive with zero-access encryption and no ads.
What does this tool do?
ProtonMail is an encrypted email service headquartered in Switzerland that uses end-to-end encryption (E2EE) to ensure only sender and recipient can read messages. Unlike Gmail, Outlook, and Yahoo which scan email content for profiling and ad targeting, ProtonMail employs zero-access encryption meaning even Proton staff cannot access user emails. The service combines email with a broader privacy ecosystem including ProtonCalendar, ProtonDrive, ProtonVPN, and ProtonPass. It supports encrypted email to non-ProtonMail users via password-protected links, offers desktop integration via ProtonBridge, and provides both free and paid tiers. The platform stores data in Swiss data centers and emphasizes jurisdictional privacy protections under Swiss law.

- Mobile app and web interface are less feature-rich than Gmail (limited filters, search functionality, and third-party integrations)
- Pricing details not publicly visible on the landing page; requires clicking through to pricing section
- No visible information about calendar sharing, collaborative features, or delegation capabilities which are standard in business email
- Limited native integration with enterprise systems and third-party tools; ProtonBridge workaround adds complexity for desktop users
