Use Custom Email Domain with iCloud Mail
When you subscribe to iCloud+, you can use a custom domain name that you already own to personalise your iCloud email address, or you can purchase a new domain.
If you subscribe to iCloud+, you can use a custom domain that you already own to send and receive email from a personalised email address with iCloud Mail.
You can use up to five custom domains, with up to three personalised email addresses per domain.
You can use your personalised email address in the Mail app on any device signed in with your Apple ID and with iCloud Mail turned on, and on iCloud.com/mail.
You can also use your personalised email address for Messages, FaceTime, Calendar, to sign in to your device and more.
If you don't have any existing email addresses in use with your custom domain, you can create new personalised email addresses after setting up your domain with iCloud Mail.
If you share iCloud+ with your Family Sharing group, you can share your custom domain with your Family sharing group and allow them to create personalised addresses. In iOS 16 or later you can also share your custom domain with people outside your Family and allow them to create personalised addresses.*
You can share your domain with up to five other people. If you add someone who's not part of your Family Sharing group, they need to accept the invitation before they're added to the domain.
If you don't already own a custom domain, find out how you can purchase an email domain to use with iCloud Mail.
* If you use a device with iOS 15 or earlier, you may not see all of the personalised email addresses that you've set up on a device with iOS 16 or later.
