Apple consolidates private email domains under a single shared domain

Apple will unify the email domains for Sign in with Apple and iCloud+ Hide My Email under a single shared domain, private.icloud.com. New addresses will be issued on this domain, while existing addresses on legacy domains will continue to work and forward mail. The rollout is planned for later this summer. Developers should update account systems, email validation, and allowlists to accept private.icloud.com, and email service providers should adjust domain-based filtering, suppression lists, and routing rules accordingly.
