The following maintenance can be done on any list to improve its quality for mailings as well as in-house administrative use:

♦ Fix/add missing zip codes
♦ Split combined fields (city/zip, names, etc.)
♦ Add gender codes to names
♦ Reformat records, put data into proper fields
♦ Sort by any criteria
♦ Search for and eliminate corrupt data (bad characters)
♦ Search for and eliminate/combine duplicate records
♦ Data quality analysis by fields or column positions

We have sophisticated matching software that can take any list and match it against any other list using name/address components and phone numbers. The resulting matches can be used for updating, enhancing/appending or suppression purposes.
