I need to change my email address. The address I put in gives me the below error. The email address it's referring to is no longer active on Etsy. I even attempted to log in with this email address and it tells me it's no longer an active account and can't be accessed.
Did you close the other email before changing the email on Etsy? I believe the code is sent to the old email address.
If you don't have access you will need to contact Etsy which you can do from here. How to Change the Email Address on Your Etsy Account – Etsy Help There is a contact support button at the bottom.
