Go to Market Pro Max –> Product Users.
Very similar to the manage members area, here you will find all of the users of your one page products.
You can export those users, manage them by email, name and product, and active or inactive. To find a user enter their email address and click on the Search button.
To delete a user, click on the Delete Users tab and you can either delete users one at a time or upload a file to delete them in bulk.
