When you sign up using your email, you will receive an account verification link in an email. If you don't see this email, please check your spam folder in case it has ended up in there. If it's not there either, it is possible that you mistakenly typed your email in wrong. In that case you will need to change your email.

To change your email, you will need to log out of your gallery and create a new account using the correct email. Don't worry, your unpublished pictures will not disappear if you do this, they are saved on your phone/iCloud and ill remain in your My Works gallery while you log out of your account and log back in using the new one.
