I'm using the Mail app on iOS 17.4.1, w/ an iCloud email address.
I do not want to change the email address associated with the Apple ID, only the display name on outbound emails.
For example, here is how my emails currently appear to somebody with a Gmail inbox:
John Brown <[email protected]>
The display name at the beginning is what I need to change, not the email address itself. I already updated my display name, under "Settings --> Apple ID --> Personal Information --> Name".
I've logged into "appleid.apple.com" and checked underneath "Personal Information --> Name", and already confirmed that it's updated there as well.
I've logged out of Mail and logged back in again.
No luck.
I understand this question has already been asked before, but the most recent answers to that question were posted in 2015, and are no longer applicable. Link.
