If you’re a ProtonMail free user, you can export emails individually and save them locally on your device.
However, paid users currently can import and export many emails at once, including whole folders or your entire inbox. This is possible using the Import-Export application.
This article includes instructions for exporting and importing emails to and from your ProtonMail account.
Using the Import-Export app
ProtonMail’s Import-Export application is available to users with Plus, Professional, Visionary, and Lifetime accounts.
If you are a free user, you can upgrade your account now through Settings -> Dashboard while logged in at mail.protonmail.com.
Once you have installed the app, you can follow the instructions to import and export emails. To import emails from another email service provider, you will have to ensure your account is configured to allow IMAP access.
