How does Apple private relay email work?

The Apple Private Relay Email is a unique, randomly generated address that acts as an intermediary (a relay) for your messages.

Its purpose is privacy: It allows you to use services like Tiger eSIM without sharing your personal, main email address.

It allows automatic forwarding: Any email sent by Tiger eSIM to your Private Relay address (e.g., abcd1234@privaterelay.appleid.com) is automatically forwarded by Apple to your actual Apple ID email inbox (e.g., youremail@example.com).

In short, All important communications (updates, verification codes, password resets) will arrive in your main inbox.
