This guide offers several solutions to quickly delete a large number of emails contained in an email address hosted by Infomaniak. Note that the size of your mailbox is not limited.

Delete emails in bulk…

… from the Infomaniak Web Mail app

1. Click here to access the Infomaniak Web Mail app (online service ksuite.infomaniak.com/mail).
2. Click on the Settings icon ‍ in the top right of the interface.
3. Click on Reception.
4. Display the maximum number of items loaded at once:
   
5. To empty the inbox:
   1. Select all items visible on the screen.
   2. A more precise selection is possible.
   3. Click on the Trash icon to send them to the trash.
   4. Repeat this process on all pages:
      
6. Apart from the inbox, folders can be emptied in a few clicks:
   1. Click on the action menu ⋮ to the right of the folder concerned.
   2. Click on Empty the folder:
      
   3. Be careful, emails are deleted without going through the trash, as if you were deleting the folder itself — only a restoration can allow possible recovery.

You can also delete the email address found within a Mail Service, then recreate it. It will then be completely empty.

… from an IMAP email software/client

A solid solution is to configure the email address in an IMAP email software/client, which will allow the selection of all messages (without the notion of pagination…) therefore the deletion is easy and quick:

1. Install Thunderbird (or any other messaging app on your device).
2. Add your email address and specify its password.
3. Wait for the inbox to load.
4. Select all messages.
5. Click on Delete.
6. That's it, you can remove the application if you wish.

Special case: crossed-out messages

To permanently delete any tracked / struck-through emails appearing in your software/email client or on Mail Infomaniak:

• Microsoft Outlook
  • go to the Edit menu -> Empty Deleted Items (in English, you should have a menu Empty)
• Apple Mail
  • go to the Mailbox menu -> Erase Deleted Items

They will then disappear from the Mail Infomaniak interface as well.
