Target Marketing by Creating Unique Mailing Lists

I recently did some research on mailing lists for a direct mail marketing campaign for a client looking to do target marketing to a combination of people with ailments and a poor credit history…  Through modeling response data, we correlated ailment responders and credit/debt responders to come up with over 81,000 records that matched.   Interestingly enough, there was over half a million in each of these files so the correlation ratio of less than 20% induced the client to test the file.  Stay tuned to find out how the response data performed.
