Assigning Email Templates

Summary

Need assistance with ensuring new user receives email

Content

As an admin, whenever an employee logs in and changes personal data, an email is triggered which notifies me of the change.   I need to ensure that a new administrator at our organization also receives this email but I cannot figure out where this is done in the system. I can see that template in my System Email Templates. I thought this would be done in the Assigning Email Templates, but this not appear to be the right area.  Where do I navigate to add the email address of our new administrator (and remove the email of our old admin)?
