Problems with Databases

A lot of our clients don't understand how important it is to keep their in-house databases in good shape - and it starts with making sure data is entered correctly to start with.  Bad data can result in unnecessary postage and print costs when there are a lot of duplicates, addresses that aren't deliverable, and worst of all....   comments entered into an address field.   No kidding - we get databases in that have comments like "he's an idiot", "owes money" or "don't deliver to this address" etc.   Can you imagine the person getting your mailpiece delivered to their home with the comment in the address field?
