Apple recently announced a major change that will unify the email domains used by Sign in With Apple and iCloud+ Hide My Email. This change will bring both services under a single domain, private.icloud.com, with the goal of simplifying email management and enhancing user security.

Currently, email addresses created through Sign in With Apple use the domain privaterelay.appleid.com, while addresses associated with iCloud+ use icloud.com. With the integration, all new addresses created for both features will be issued at the new domain private.icloud.com. This change is expected to be completed this summer, with no action required from users.
This move by Apple aims to provide a more unified and secure user experience. Unifying domains makes email management easier and enhances user privacy. Apple is known for its emphasis on security and privacy, and this change is part of its ongoing effort to protect its users' personal data.
For regular users, this transition will be smooth and hassle-free. Existing email addresses using the old domains will continue to function normally, and emails will be forwarded without any interruption. This means that users will not need to make any changes to their settings or worry about data loss.

However, developers and email service providers should be prepared for the changes. Developers who have apps or websites that use Sign in With Apple will need to ensure that their account systems, email validation logic, and whitelists accept addresses in the new private.icloud.com domain, in addition to existing domains. This requires an adjustment to their systems to ensure that their services continue to function smoothly.
Additionally, email service providers may need to update their systems to include the new domain. This may include updating domain-based filtering, suppression lists, or routing rules. This adjustment is necessary to ensure that emails sent from the new domain are delivered correctly to recipients.
Apple's decision to unify email domains is part of a broader strategy to strengthen security and privacy. The company has invested significantly in technologies that protect its users' personal data, and this change is another step in that direction. By unifying domains, Apple offers a more consistent user experience and makes it easier to integrate its services.

This integration is further proof of Apple's commitment to providing secure and reliable services to its users.
