Email masks are masked, or private, email addresses that forward messages to your true email address. These masks allow you to share an address with third parties which will mask your true email address and forward messages to it.

You can use ⁨Relay⁩ email masks most places you’d use your regular email address. We recommend using them when signing up for marketing/informational emails where you may want to control whether or not you receive emails in the future.

We don’t recommend using masks when you need your identity verified or for very important emails or those where you must receive attachments. For example, you’d want to share your true email address with your bank, your doctor, and your lawyer, as well as when receiving concert or flight boarding passes.

Yes, you can generate ⁨Relay⁩ masks on other browsers or mobile devices simply by logging in to your ⁨Relay⁩ dashboard.
