Pokemon Go Verifying Wrong Email

I had the same problem, I just happened to write the email account for my friend's account. If you haven't pressed the "vertify" button on the app but just closed it, you can go in on the webbrowser and sign out of your account on google, then open the app again and sign up with google. Then you can just sign in and it worked for me. So that can definitely be an opportunity if you messed up like I did. :)
