adding additional email account

Hi there OGNation,

You certainly can have additional emails with your iCloud account. They are called aliases, and this article has more information about them, how to make them, etc., named:

iCloud: Create or change email aliases

Thank you for using Apple Support Communities.

Cheers,

I have the same question, but not looking to set up an alias. Want to share my iCloud account with another family member with a separate iCloud email address.

Thank you for the clarification. For that, you would need to create an additional iCloud account using a different email address and this article will help you do that:
