When you use the Mark Selected Item(s) as Spam feature in XFINITY Connect, the email you mark is sent to a database. There it is compared to other messages that are reported as spam.
By marking an email you are not automatically blocking the sender, but it will be moved to your Spam folder. While this should re-route any future emails from that sender to your Spam folder, it is possible that 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 are 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 twelve Internet service providers in North America.
