If you have a new email address, you can change the email associated with your Admincontrol user account without creating a new account. By doing this, you will retain all information stored in your current account.
Go to https://login.admincontrol.net/ and enter your login details.
Navigate to 'My Profile' and select 'Edit Profile.'
Enter your new email address in the 'Email' field and click 'Save.'
The new email address has to be verified for the change to take place. A verification email will be sent to your new address. To complete the change, open the email, click on the 'Verify Email Address' link, and log in to the service.
