Apple has increased the number of custom email domains that iCloud+ subscribers can configure from three to 10. The expanded allowance appears in Apple's updated iCloud support documentation, giving subscribers more flexibility when using custom domains with iCloud Mail.

The change follows a separate increase to the number of iCloud Mail aliases users can create. That limit rose from three aliases to nine, making the custom-domain expansion the second recent increase to an iCloud email-related allowance.

What iCloud+ custom domains do

iCloud+ subscribers can connect a domain they already own to iCloud Mail. This allows them to use an address such as name@yourdomain.com instead of an address ending in @icloud.com.

Apple also allows users to buy a new domain while setting up the feature. The custom domain option is designed for people who want to use a personal or other branded email address while keeping it connected to iCloud Mail.

What has changed for subscribers

Apple's support documentation now lists a maximum of 10 custom domains, compared with the previous limit of three. The higher limit could be useful for subscribers who manage email addresses across multiple personal projects, organisations or businesses, although Apple has not announced a separate explanation for the change.

The updated limit was spotted by the X account pdfu. Apple's support page is the source for the current allowance, while the company has not been described as making a formal announcement about the increase.

iCloud Mail limits are expanding

The custom-domain change gives iCloud+ users substantially more room to configure separate domains. It also shows that Apple's recent adjustment to email limits was not restricted to aliases.

Users who already have iCloud+ can check Apple's support documentation for the current custom-domain setup requirements and supported configurations. The available allowance applies to iCloud+ subscribers using custom domains with iCloud Mail.
