There are many things to consider when ordering any list, but medical lists have some unique things to consider. Some questions to ask yourself:
A new service has become available for getting mailing lists of doctor's addresses from the AMA. The AMA list, while usually a better quality list over compiled directory lists, is quite expensive with minimum orders of 5,000 records or more. In those cases where you only want a small quantity, the cost is the same as if you ordered 5,000 records. But now, there is a prepay service available to that makes it easier and cheaper to order those lists that are smaller when mailing to a small regional area.
