How Can I Stop E-mails From Going To The Wrong E-mail

I'm not sure what you are asking.  An email address is like a home address, your mail comes to your address same as for your email address.  If you mean you want to change an address for the email to go to, you simply go to the site that is ending the email ( a news letter, for example), sign into your account, go to where you update your information and change your email address, save and exit.  If you are truly getting email mixed up and delivered to the wrong address, contact your email provider (go to the help page) and find out what is wrong.  Your email account may have been compromised (hacked).  Do it immediately and change your password now!
