When you try to bind an email address and see the prompt as shown in the image above states, "This email has already been bound, please go back and re-enter," it means that the email you entered is already associated with another SWAG account, which you might have forgotten.

If the mobile number or email address you wish to bind has been accidentally linked to another SWAG account, you can delete the old account and bind the previously registered email address.

If you want to use both accounts, please change the email binding of the SWAG account you currently want to operate with to another email address that has not been bound before (an email address can only be bound to one SWAG account, and diamonds cannot be transferred or merged between different accounts).
