How to delete alias Apple ID

Hi Dhejsbdjdh,

Thank you for using the Apple Support Communities! To manage email aliases for iCloud, you'll want to follow the guidance below:

Add and manage email aliases for iCloud Mail on iCloud.com

Turn off, turn on, or delete an alias

You can turn an email alias on or off at any time. You can also delete email aliases that you no longer want to use. While turning off an email alias is temporary, deleting it is permanent. When an alias is turned off or deleted, email sent to that alias is returned to the sender.

1. In Mail on iCloud.com, click  at the top of the Mailboxes list, then choose Preferences.

2. Click Accounts, select an iCloud Mail alias in the list, then do any of the following:

* Turn off an alias: Select “Disable alias.”

* Turn on an alias: Deselect “Disable alias.”

* Delete an alias: Click “Delete alias,” then click Delete.

6. Click Done.

Hope this helps!

Have a great day.
