About:
The ProtonMail Import-Export app is an official desktop application that allows ProtonMail users to securely transfer emails between their ProtonMail account and local storage. It supports importing emails from other providers (via MBOX or EML files) into ProtonMail's encrypted inbox, as well as exporting emails from ProtonMail for offline backups or migration purposes. The tool ensures end-to-end encryption is maintained during the transfer process, aligning with ProtonMail's security standards.
Key Features:
  • Import emails from MBOX/EML files into ProtonMail
  • Export ProtonMail emails for offline backups
  • Maintains end-to-end encryption during transfer
  • Official ProtonMail desktop application
  • Cross-platform compatibility (Windows, macOS, Linux)
Use Cases:
  • Migrating from another email provider to ProtonMail
  • Creating encrypted offline backups of ProtonMail emails
  • Transferring emails between ProtonMail accounts
Alternatives:
  • Thunderbird – General email client with import/export but lacks ProtonMail's built-in encryption integration
  • imapsync – Command-line tool for syncing IMAP mailboxes, requires manual setup and doesn't handle ProtonMail's encryption natively
