Apple has quietly expanded custom email domain support for iCloud+, raising the limit from three domains to ten.
The change gives subscribers considerably more room to host email from domains they already own through iCloud Mail.
Someone managing separate domains for a personal website, family, side project, or small business can now keep more of those addresses under the same iCloud+ subscription.
Your iCloud+ subscription can replace more email hosting
Custom Email Domain lets you replace the standard @icloud.com address with email from a domain you own.
If you own example.com, for instance, you could send and receive mail using an address such as name@example.com while iCloud handles the email service behind it.
Because custom domains are included with iCloud+, Apple doesn’t charge a separate email-hosting fee.
Expanding the limit to ten makes the feature considerably more practical for someone currently paying another provider to host several personal domains.
You can also share custom domains with members of your Family Sharing group, extending those personalized addresses to other people without setting up a separate email service for each person.
The expansion comes alongside another recent change to iCloud Mail. Apple raised the number of standard aliases from three to nine, giving regular iCloud Mail users more addresses they can use without exposing their primary email.
More domains still share one inbox
Connecting additional domains doesn’t create separate inboxes for each one. Messages sent to your custom addresses continue flowing into iCloud Mail alongside your other email.
That may be perfectly manageable with two or three domains, but ten could get crowded quickly.
Mail rules can automatically move incoming messages into folders, so you can keep work, personal, or project addresses separate without maintaining entirely different email accounts.
The new 10-domain limit is already reflected in Apple’s iCloud Mail support documentation and is available to iCloud+ subscribers.
