Internet email accounts are not affected by which mode of internet access you choose.

Keep ‘em coming, please.
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.
Years ago I got so frustrated having to change email addresses that I registered my own Domain name. Now I just forward my email from my own domain to whatever internet provider that I am currently using and my email address never changes.
