Purchase a new email domain and add it to iCloud Mail on iCloud.com
If you upgrade to iCloud+, you can purchase a custom email domain and use it with iCloud Mail. You can also add a domain you already own to iCloud. See Add an email domain you already own to iCloud Mail on iCloud.com.
You may have up to five active custom domains configured with iCloud Mail.
Note: Custom Email Domain is not available in all countries or regions.
Before you begin
You need to have two-factor authentication enabled for your Apple ID. If you do not, you can turn it on at the Apple ID account website.
You need to have a primary iCloud Mail email address set up to use a custom email domain. If you do not, see Create a primary email address for iCloud Mail.
Purchase a domain
On iCloud.com, tap
in the toolbar, then tap Custom Email Domain.Tap “Buy a new domain”.
Note: If you have already added at least one domain, you may need to scroll down before you see “Buy a new domain”.
Enter the domain you want to buy, then tap Search.
Choose an available domain, then tap Continue. A new window opens. Follow the onscreen instructions to purchase the domain.
After the domain purchase is complete, return to iCloud.com and choose who will use the domain:
Only You: Choose this option if you are the only person who will use the domain. You are asked to create your first email address.
You and Other People: Choose this option if you want to share the domain with friends or family members. You may now choose who can use the domain. See Add or remove people sharing a custom email domain on iCloud.com.
