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.
