Q: How do I change my iCloud email name? I just got married and would like to have my could email with my new married name...is that possible

You can create an alias using your desired address. Open Mail/Preferences/Accounts/Account Information and in the dropdown box for alias, select Edit.

So my current iCloud email is firstname.lastname@icloud.com like most people.  However, I just got married and would like my email address to reflect that meaning firstname.marriedname@icloud.com.  Is that possible?
