  • System tray integration and native notifications
  • Secure local storage of encrypted data
  • Multi-account support
Use Cases:
  • Managing ProtonMail emails from a dedicated desktop application
  • Accessing encrypted mailbox data while offline
  • Improving workflow efficiency with native OS notifications
Alternatives:

  • Proton Mail Web – Official web interface accessed via browser.
