If you put the wrong email and unable to verify the email, you can change by yourself on the Profile tab. When you press the 'Verify' button next to the email on Profile tab, the window that confirms your email will pop up. On that window, you can change the email. If you change the email on the input field, the bottom button is automatically changed to 'Change' from 'Verify'.
After you type in the right email, press the 'Change' button. Then, the verification email will be sent to the email you typed in. Also, you'll see the email is already changed on the Profile tab.
If you have already verified your email, you will not be able to see the 'Verify' button. In case of changing the verified email, RedKiwi team has to change it directly. Please send us a message. We'll change it instead of you :)
