How to change your email on this web site? I want to change my email to another one?

Is it like a newsletter? cause at the bottom of most newsletters it says "unsubscribe" you could hit that and unsubscribe from the newsletter and then create the email (What email are you using? Gmail,AOL,Road Runner, ect.) Then go back to the website and subscribe to the site just as you did before but with the new email. Does that answer your question? Or are you thinking like you made a email from the website and you want to change it? If so i personally use Gmail and the only way i know how to change it is to create another account and sign up for all your newsletters again. There must be an easier way to it then that but that's all i know, hope I helped!
