Hey williamfromsnoqualmie,
To manage the addresses used, follow these steps: Create and manage Hide My Email addresses in Settings on iPhone - Apple Support
You can create and manage Hide My Email addresses in Settings
. Go to Settings > [your name] > iCloud > Hide My Email, then do any of the following:
• Create a Hide My Email address: Tap Create New Address, then follow the onscreen instructions.
• Deactivate a Hide My Email address: Tap an address (below Create New Address), then tap Deactivate Email Address. After you deactivate the address, it no longer forwards emails to you.
• Change which personal email address to forward to: Tap Forward To, then choose an email address. Options consist of addresses that are available with your Apple ID.
• Copy a forwarding address to use elsewhere: Tap an address (below Create New Address), touch and hold the Hide My Email section, then tap Copy. To immediately use that address elsewhere, touch and hold in a text field, then tap Paste.
Thanks for participating in Apple Support Communities.
Take care!
