As an administrator, you can manage users with access to your ATOMIZED account by navigating to the Account Panel at the top right of the screen, and selecting the Users tab. To manage Campaign access for users, use the Admin Dashboard.
On the Users Tab of the Account Panel, a list of all users with access to the ATOMIZED account will be listed. Users can be suspended (removes the ability for that user to log in to the application), restored while retaining access if they are restored), promoted to an Account Admin, or demoted from an Account Admin.
Additionally, new users can be invited and granted access to any campaign in the account using the 'New User' button at the top right.
