Is " [Edited]" a legitimate email address from Xfinity/Comcast?

An elderly friend of mine received an email regarding updating their Gateway and it came from " [Edited: "Personal Information"]". The email was forwarded to me and an image is missing from it. I just need to know if it's legitimate or not so I can help them upgrade their equipment, if necessary, or tell them to disregard the email and not to click on anything.
