How to remove hide my email

Welcome To Apple Support Community!

You can create and manage Hide My Email addresses in Settings > Name > iCloud > Hide my email

You can use Hide My Email to keep your personal email address private. With Hide My Email, you can generate unique, random email addresses that forward to your personal email account, so you don’t have to share your real email address when filling out forms or signing up for newsletters on the web or sending email.

To deactivate Hide My email: Settings > name > iCloud > hide my email >  Tap an address (below Create New Address), then tap Deactivate Email Address. After you deactivate the address, it no longer forwards emails to you.
