The best way to ensure only your preferred carriers see your postings is to use Priority Booking, located at one.dat.com. Here, you can offer loads to only your private network instead of the entire DAT load board.
As a broker, after logging into one.dat.com you will see options on the left side that include Private Loads, Search Loads, My Shipments, and Private Network. You will need to add carriers to you private network to get started. After you have built your private network, you can post your loads using the Private Loads tab. Your loads will be visible only to those carriers in your private network. You can set a price, or have the carriers in your private network bid for the loads. When you post a load to your private network, each carrier will get an email, alerting them to your new loads. This Priority Booking system gives you control of who sees your loads.
