How ⁨Relay⁩ email & phone masking works

  1. Use ⁨Relay⁩ email masks and phone masks everywhere

    Get secure, random email masks and a unique, masked phone number to use any time a website, app, store, or restaurant asks for your information.

  2. We’ll forward emails, phone calls, and texts to you

    Rest assured, senders will never know your real email address or real number. You can even reply to texts and emails without sharing your real identity.

  3. Manage your masks from your ⁨Relay⁩ dashboard

    Sign in to your ⁨Relay⁩ dashboard to create new masks, label existing masks, and block calls, texts, or emails from masks that get too much spam.

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.
