Not necessarily true.
My ISP is Comcast. If I cancel my internet service through Comcast, any email accounts I have on Comcast are terminated by Comcast when I cancel my service. I would not have the option to keep them.
Any email accounts I have on an email service provider such as MSN.Com, Hotmail.com, gmail.com, yahoo.com (you get the picture) would remain since those email addresses are not hosted by Comcast.
The thing to remember is this: If the email account is hosted by the ISP and you cancel your service, you're losing your email. This is why most people use gmail, yahoo, hotmail, etc.. for their "common" internet email address.
Not necessarily true.
I agree with your scenario but I was referring strictly to internet based email addresses such as yahoo, gmail, hotmail, mail.com, etc. I believe this poster has an internet based email. I was informing him that there would be no problem accessing it from any internet connection. Even though Comcast and other ISP’s provide for internet access to your account, they are proprietary ISP’s and won’t provide continued access once you switch to another ISP.
