Identify official emails for the Comcast.net email upgrade to Yahoo Mail

Starting in June 2025, customers with a comcast.net email will be invited to upgrade their email accounts to Yahoo Mail for a better experience at no extra cost. Invitations will roll out gradually through 2026, and when the time comes, you’ll see yours in your inbox or when you securely sign in to connect.xfinity.com.

During this transition, you may receive fraudulent emails claiming to be from Xfinity or Yahoo support.

Yahoo Mail migration safety tips

Below are some tips to help you stay safe and protect your account:

  • Check the sender: Valid emails regarding this move will come exclusively from xfinity@updates.xfinity.com.
  • Look for the verified email logo: If you are accessing your email through webmail, official messages from us will always display the Xfinity verified email logo.
  • Be wary of urgency: Scammers often use threatening language (e.g., "verify immediately or lose access") to make you act without thinking.
  • Protect your password: Xfinity will never ask you to reply to an email with your password or sensitive personal information.
  • Verify the website: You will only be asked to accept Yahoo’s Terms of Service after you securely sign in at connect.xfinity.com and are redirected to Yahoo’s official website.
