Same email address. Smarter inbox. Zero cost.
How to make the switch to the Yahoo Mail platform
You’ll get an email from xfinity@updates.xfinity.com inviting you to upgrade to a Yahoo Mail account. We’ll walk you through if you have multiple email accounts.
Didn’t get an invite yet? Invitations are being sent through 2026, so just sit back, relax, and continue to access your Comcast.net email as usual until you get an invitation.
Your emails, folders, and contacts will transfer automatically. But some things won’t move like attachments over 25 MB, over 4,100 folders, or over 10,000 contacts.

Frequently asked questions
We’ve chosen to partner with Yahoo Mail to provide customers with a comcast.net email the ability to upgrade their email account to Yahoo Mail for a better email experience at no extra cost. If you choose to upgrade to Yahoo Mail, your email address, messages, folders and contacts will stay the same. Yahoo Mail provides a ton of great features, including enhanced security, smart and intuitive calendar features, AI-driven tools to streamline your inbox management, and a mobile app so you can stay connected on the go. The upgrade to Yahoo Mail does not impact any paid services customers may have with Xfinity.
All active comcast.net email accounts, including those used by current and former Xfinity customers, will have the option to upgrade to Yahoo Mail. An email account is considered active if it has been signed in to within the past two years.
Once you’re invited to upgrade your comcast.net email account to Yahoo Mail, you’ll see a prompt to accept Yahoo’s terms of service when you securely sign in to your email at connect.xfinity.com. If you have more than one comcast.net email account associated with your Xfinity account, you will need to sign in to each email account and accept the Yahoo terms, as each mailbox will be treated separately.
Below are a few tips to ensure a smooth transition:
- Download and delete any emails with attachments totaling more than 25 MB since we will not be able to move them. Otherwise, they will be moved to a separate folder in your Xfinity Email inbox, and you will be notified that you have 30 days to download them.
- Reduce or consolidate your mailbox if your folders exceed 4,100 or contacts exceed 10,000. Yahoo Mail can only move up to 4,100 folders and 10,000 contacts per mailbox. If you exceed 4,100 folders, your folders will be consolidated upon moving. You will lose any contacts over 10,000.
Yes. You will need to:
- First, accept Yahoo terms of service when prompted after signing in to connect.xfinity.com.
- Then, change the configuration on your third-party client to reflect the settings on your new Yahoo Mail account so you can continue to access your email there in the future.
Steps on how to set up your third-party app with Yahoo Mail.
Yes with a few exceptions:
- Email messages with attachments of more than 25 MB or in an unformatted format will not be moved. They will be moved to a separate folder in your Xfinity Email inbox, and you will be notified that you have 30 days to download them. Only up to 4,100 folders can be moved. Folders over 4,100 will be consolidated into a single folder.
- Folders with names over 240 characters will be moved; however, the folder names will be automatically truncated prior to moving.
- Only up to 10,000 contacts can be moved.
- Any user-created folders with names matching Yahoo system folders (like “Sent” or “Drafts”) will be renamed in Yahoo Mail.
