How to Keep Comcast Email

... is there any way that I can still keep access to this email without using Xfinity as my ISP?

Please see https://www.xfinity.com/support/articles/using-email-only  and https://www.xfinity.com/support/articles/email-only-faqs. 

Although you can keep your @Comcast.net address, it would probably be best to begin migrating to one of the (often free) independent email only providers like Outlook.com, Gmail.com, Yahoo.com, etc. That way you wouldn't have to change it again even if your ISP changes.

How  did this work for you? I'm wondering if you still have access to this forum. Were you able to keep your Comcast.net address? I've been a customer since the being.
