I've never used one - I've actually never had a marketing department at all. The people I want to market to are existing clients whom we simply haven't spoken to. The nature of my business is embedded within claims department at major insurance companies but the issue we've run into is that our users simply are not aware of all the services available to them. those whom have been using us for years - through no fault of their own - think we specialize in the couple claims types they've sent our way for years and can't believe it when they find out their employers service contract allows them to effectively send anything they receive for our services. If I could pay just anyone to make dials and send emails I would but given the nature of my clients operation policies - traditional methodologies and nothing else can't be it. Any thoughts?
