The Import-Export application is available to Plus, Professional, Visionary, or Lifetime account owners and helps you export (i.e., download) decrypted emails from your ProtonMail account to your device. You can then view the messages or import them into another email account or email client. This article explains how to use this app.
2) Log in to the Import-Export app using your ProtonMail username and password
3) There are two export options:
The first option is Export All. This option allows you to export emails from all your email addresses.
The second option is Export. This option allows you to export emails from individual email addresses. You can use the Export option by clicking on your username and choosing the Export button next to the email address you wish to export. Clicking one of these two options will bring you to the next step.
4) The next window asks you to “Select what you’d like to export”
There you can select which Folders, Custom Folders, and Labels you want to export.
You can select a specific time frame for the emails you wish to export by deselecting the default “All dates” and choosing a start and end date.
You can also choose whether to export messages as MBOX or EML files. (Click here to learn the difference between these two file formats.)
If you have emails in your Mailbox that cannot be decrypted, they will not be exported unless you check the box next to “Export emails that cannot be decrypted as ciphertext”. Most users will not need to check this box.
Finally, select the location where you would like to download the the folder containing to the exported messages. Change the destination by clicking on the “Browse” button.
5) Then click on “Export”.
