Not all merge/purge software and processing are the same!
Some mailing list cleaning programs delete only identical matches — for example, “123 Elm Street” and “123 Elm Street.” They might not identify “123 E. Elm St.” and “123 Elm Street” as a match.
Other programs might think “37 Fulton Avenue” and “37 Fullerton Avenue” are a match when, in fact, they are two different locations.
KD Mailing & Fulfillment’s cutting-edge merge/purge software standardizes and corrects all possible addresses in your lists, then creates a special merge/purge sequence to eliminate the true duplicates and keep the good addresses.
We can even identify sound-alike names (“Dennis” and “Denis,” for example) at the same mailing address and eliminate the duplicate.
We can give you reports showing precisely where duplicates appeared and what we eliminated. This is important when you are renting lists and have a “net name” arrangement with the list owner.
