Q: Can a Cargomatic shipper or carrier contact me directly?
A: According to our Terms of Service, it is strictly forbidden for either party to solicit business from one another for 12 months from the last date of a shipment between the parties. If this occurs, both parties will be asked to cease and desist and are subject to being asked to leave the marketplace.
AFAIK, the norm for load boards like DAT is to contact directly and settle a deal through external communication (i.e. not through the load board).
I can see some convenience to having such a closed/end-to-end system, but seems like, as a shipper, it would be limiting your supply of capacity.
