How do I change my account's login email?

Hello @MelissaC48 ,

You can update your account's main email address on the My Account page. If your username is the same as that address, you can update it through the My Account page as well. You can update the account's billing address under the billing subtab of My Account. 

Keep in mind that only addresses you've verified are available for use as the main account email, sending address, or billing address.
