If you use a web-based email provider, like Gmail, Outlook, or Yahoo there is no need to make a change. Access to your email will not change. If your email is hosted through your previous internet service provider, you will want to check their policy for continuing access. Comcast's website indicates that as long as you log into your account before you cancel service and then log in at least once every nine months you can keep your email address with them.
You may review the document below for additional information about switching or transferring email addresses. Also, as part of your Whip City Fiber service, you may request five free email accounts (your email@example.com) from firstname.lastname@example.org.
