Set up list, edit or delete list, etc. Your customers will be assigned their own List Admin Area. Review subscribers and removes by the day, week, month or year. Many folks do not know how to set up the subscribe, unsubscribe box on their website. The system generates a html code for the customer to put on their website that does this function for them.
Customers can view their entire list anytime they wish.
Think about the uses for this system. Give a List Server to a customer as an incentive to buy.
