How to Manage Your Xfinity Email Settings - My Account Help
You can change the email address where you receive Xfinity account alerts and communications in My Account. Your comcast.net email is usually set as your default preferred address, but you can change your preferred email at any time.
To add a personal email address to your account, follow the steps below:
Sign in to My Account and make sure you're on the Users tab.
Select Edit next to the user you want to add an email address for.
In the Contact Information section, click Add a Personal Email Address. (Note: If there is already a personal address associated with the username, you can click Remove and start these instructions over or click Edit to make any necessary changes).
Enter and re-enter your email address. Click Save.
We'll send a verification link to validate your new email address. For your security, your email verification link will expire in 72 hours.
Note: Your comcast.net email address will remain your default preferred address until you update the setting in My Account.
Set Your Preferred Email Address
To set a personal email as your preferred address, you must first add a second email address to your account via the instructions above.
