Set up a custom email domain for iCloud Mail on all your devices
If you or someone in your Family Sharing group has an iCloud+ subscription, you can add a custom email domain you already own to iCloud using your iPhone or iPad, or on iCloud.com. For an overview of the feature, see Personalize iCloud Mail with a custom email domain and share with others.
After you set up a custom email domain, you can send and receive mail from that domain on your iPhone, iPad, Mac, and Windows device, and on iCloud.com. Make sure you’re signed in to the same Apple Account on each device. If you’re not signed in to your Apple Account on a device, or the device has the Mail feature turned off, you won’t be able to see your mail on the device.
Note: You need to have a primary iCloud Mail address in order to use a custom email domain. If you haven’t set one up, see Create a primary email address for iCloud Mail.
