Secure personal data
with private relay feature
Now users can subscribe to any service they wish, but keep their data private. Apple’s new feature allows hiding the actual email address by generating a random and unique one. Here’s how it works!

Private Relay Email is an innovative feature that allows hiding a user’s private address. You can also call it Hide My Email. The feature helps secure personal data. Suppose the user decides to hide the email when creating an account on your website. In that case, the Private Relay feature will automatically replace the original email with a random set of letters.

Imagine that [email protected] is your Apple ID. When you Sign in with Apple, the Private Relay feature will provide you with a unique email, e.g., [email protected]. You will receive communications from the particular service on the private relay address. Another advantage is that you cannot reuse it for another app or website.
Is this a good step towards the security of personal information?

However, as email marketing specialists, we face situations when we need to know a private email address or link the fake one to the original one. For instance, we won’t be able to connect the user’s previous activity, if he:

  • Contacts the support team from the original email address
  • Performs bank transactions on the service
  • Requests to restore subscriptions or purchases on the website
  • Asks to delete your personal data due to GDPR
The situation intensifies when the user wants to reveal the connection between the private relay email.

How to disclose the actual email addresses?

Headway uses the 3d8712c2 prefix so that their users could reply to their messages. You don’t need it if you try to disclose the personal email address.
2. Ask the user to send you a screenshot or the text from the ‘From’ field.
If the user uses the Private Email feature, the ‘From’ field in all communications will look like this:

[email protected]

To disclose the original email, go back to the first point and repeat the actions.
