Hi, 
1. To protect your privacy and data security, we suggest removing your email address from this thread.

2. To bind the camera from a TP-Link account to another one:

    1) Please hold the reset button on the camera for 10 seconds to perform a factory reset when it's online to unbind the camera from the original TP-Link account, or you can remove the camera from the Tapo app to unbind it from the original account.
    2) Refer to the following instructions to register a TP-Link account with your new email address: What is TP-Link ID, and how to create a TP-Link ID?
    3) Log in to the Tapo app with the new TP-Link account, and then reconfigure the camera to bind it to the new account.

Best Regards
