Need more than 3 personalized email addresses
I have an existing custom email domain for my family via GoDaddy and we have 6 family members who use it. This includes my immediate family of four and my parents. My immediate family are members of my iCloud family, and my parents are not. So here's the question: Is it possible for all 6 of use to use the custom domain with iCloud mail even though each of us only uses 1 personalized email address, or is the custom domain limited to 3 personalized addresses in total?
