How do I change display name for iCloud email in Apple Mail?

I'm still having the same problem. What shows in my Full Name field is not what appears when I actually send an email. What else can I do?

TI change the sender name on your Mac mail you change it on iCloud.com as discussed. To change the sender name on an iOS device, go to Settings>Mail,Contacts,Calendars...tap iCloud under Accounts, tap your iCloud account at the top of the next screen, tap Mail at the bottom of the next screen, then enter the name you want to use in the Name field at the top.

If you're talking about the sender name (the name that appears on the From line when you send email), to change it on your Mac Mail, go to icloud.com, sign into your account, open Mail, click the gear shaped icon on the bottom left and choose Preferences, go to the Accounts tab and enter the name you want to use in the Full Name field and click Done. Then quit Mail on your Mac (Command-Q) and re-open it. Your new From name should now appear in the drop-down list when you compose a new email.

You're welcome. You too.
