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.

Report spam and phishing emails when using an email app

If you use a third-party email app (such as Outlook or the email app on your mobile device) to access your comcast.net email, you can still report spam and phishing messages. Here’s what you need to know:

Most email apps include a Spam or Junk folder. To report spam or phishing, drag the suspicious email into the Spam folder. When you do this, your email app automatically sends a spam complaint to Comcast. This helps improve spam filtering and protect your account.

Examples of third-party email apps include:

• Apple Mail (app Name is "Mail" on iPhone, iPad, or Mac)
• Gmail app (on Android devices, and personal computers)
• Outlook
• Yahoo Mail app

What if your email app doesn’t have a spam folder?

Some apps may not include a spam or junk folder. If you don’t see one, log in to Comcast Webmail at connect.xfinity.com. Select the suspicious email and click the Spam button at the top of the page.

Why reporting spam and phishing emails matters

Reporting spam and phishing emails helps keep your inbox safe. It protects you and other email users from scams. Your reporting helps email and internet providers spot scammers, making the internet a safer place for everyone.
