Abstract
A system and method for protecting against redundant mailings compile mail listings associated with, for example, refund promotion requests received during a given period of time for a number of different refund promotions. Each listing in the compilation is compared on an automated basis with one or more other listings in the compilation according to one or more rules defining a first statistically significant event to identify suspicious listings. Listings in the compilation are also compared on an automated basis to listings previously identified as suspicious and may also be compared to listings associated with known abusers and complainers. Listings identified as suspicious are thereafter compared on an automated basis according to one or more different rules defining a second statistically significant event to identify redundant mailings.
