Do i have to change email address after changing isp?

I have recently changed from bt to talktalk and wondered if it is still ok to use and access my emails on yahoo. My email address is for bt yahoo and ends with @btinternet.com. I did create another email address for yahoo, but would obviously prefer to use the first one as all my emails, yahoo questions and other things are stored there.Do i have to change email address after changing isp?No, you dont need to change email addressDo i have to change email address after changing isp?You don't have to change your email address, but I believe you're required to change your political affiliation.Do i have to change email address after changing isp?If your present %26quot;screen name%26quot; is not in use with the new ISP, you can use it, but your ISP is different and will actually change your %26quot;address%26quot;.Do i have to change email address after changing isp?No why just log in with ur id
