What are the benefits of having an iCloud email with a custom domain?

With the new paid subscription for Apple’s cloud service, users can now freely design their iCloud email address how they want. So instead of using standard addresses that follow the same pattern, it’s now possible to use custom domains like You can use this domain to send iCloud emails as you normally would.

Linking the iCloud to your personal domain can pay off for a variety of reasons:

  • Companies can gain respectability by using personalized domains.
  • Emails from a custom account appear more professional than emails from an address.
  • A custom domain offers maximum flexibility when it comes to hosting.
  • You can use your own email domain with iCloud and also with any other mail platform.
  • You can decide which provider you register your address with.
