How to Whitelist Email Addresses on Comcast
Pinterest Stumbleupon Whatsapp

Few things are as annoying as missing an important email because it got marked as spam and sent to your junk box before you even had a chance to look at it. It may not happen often, but when it does… ugh.

If you use an email account provided by Comcast, you can get around this by whitelisting certain email addresses.

  • Sign into your My XFINITY account.
  • At the top right, click the Mail icon to reach your inbox.
  • Click the Address Book tab.
  • Click New Contact on the left sidebar.
  • Add the sender’s email address.
  • Click Save to save the contact.

From now on, emails from this address will never be marked as spam.

Pro Tip: If you’re being inundated with spam, you may be making some serious email mistakes that you should be avoiding. Try practice good email security habits from this point forward!

    Hi there. Checking in from the Comcast Email Team.
    Unfortunately, spam filtering (and therefore whitelisting) is far more complex than what this article covers. Because of this complexity there is no “whitelist.” If a message is flagged as spam by our customers, we will treat it as spam, and simply placing an address in your address book will not bypass spam filtering.

    We are very transparent about how our spam filtering works. Please read our FAQ, which can be found here:

    We hope this helps clear things up.
