Mark emails as spam — Xfinity Email help

Learn why and how to mark an email as spam.

What happens to spam in email

When you use the Mark Selected Item(s) as Spam feature in Xfinity Email, the email you mark is sent to a database where it's compared to other messages reported as spam.

By marking this selected email as spam, you are moving it to your Spam folder, but you aren't automatically blocking the sender. This should reroute any future emails from that sender to your Spam folder, but it's possible you may still receive some emails from the same domain in the future.

If you want to automatically block email from a certain email address or domain, you can set up an email filter. Learn more about setting up spam filters and blocking emails.

With every email you mark as spam, you're helping to train a universal filter that will help block future spam. These filters are not only influenced by Comcast customers reporting spam, but also by nine of the top 12 internet service providers in North America.
