Acerca de

Proton Mail es un servicio de correo electrónico cifrado que proporciona cifrado de extremo a extremo y cifrado de acceso cero para proteger la privacidad del usuario. Fundado en 2013 en el CERN por Andy Yen, Jason Stockman y Wei Sun, Proton Mail tiene sede en Suiza y está protegido por las leyes de privacidad suizas. El servicio cifra los correos electrónicos en el lado del cliente antes de que lleguen a los servidores de Proton, asegurando que ni siquiera Proton pueda leer los correos electrónicos del usuario. Las características incluyen mensajes autodestructivos, correos electrónicos protegidos por contraseña para destinatarios que no son de Proton, dominios personalizados, alias de correo electrónico y búsqueda avanzada. Proton Mail se integra con el ecosistema más amplio de Proton incluyendo Proton VPN, Proton Drive y Proton Calendar. La aplicación admite cifrado PGP y ofrece una de las soluciones de correo electrónico más integrales enfocadas en privacidad disponibles en dispositivos móviles y de escritorio.

Proton Mail is the most credible privacy-focused email service available, and its CERN origins, Swiss jurisdiction, and zero-access encryption architecture provide a genuine alternative to surveillance-model email providers. End-to-end encryption means even Proton cannot read your messages, and features like self-destructing emails and password-protected messages to non-Proton recipients extend privacy beyond the ecosystem. PGP support adds interoperability with other encrypted email systems. The broader Proton ecosystem (VPN, Drive, Calendar) creates a cohesive privacy-first platform. Swiss privacy laws offer meaningful legal protection. The free tier includes 1GB of storage and limited daily messages, which is functional for light use. As a general email app, the encryption-first design introduces friction -- search is more limited than Gmail, and the interface, while improved, is less polished than mainstream alternatives. The bundled Proton VPN is a useful addition but more basic than dedicated VPN services. For users who prioritize privacy over convenience, Proton Mail is the clear leader. For typical users who just want email to work effortlessly, it requires accepting tradeoffs.
