Advertisers are able to subscribe to zones that are sold out through our waiting list feature. When they click add to my waiting list they are added to a waiting list you can see in your Publisher Dashboard. You are only able to see the number of people waiting, not who is waiting. When the zone opens up because of an ad being canceled or a new spot being added to the zone an email is sent. This email goes to the Advertisers who are on the waiting list to tell them that the ad zone is now available for purchase.
We tend to answer most support tickets during normal business hours: Monday to Friday, 9:00 am to 6:00 pm (EST). However, we're constantly monitoring tickets, and we'll address urgent issues on nights and weekends, too.Open a Ticket
