Data Cleaning and Processing

Data cleaning is the process of improving data files and databases by removing or correcting data that may be incorrect, out of date, incomplete, duplicated, or irrelevant.

Personal data can go out of date very quickly unless it is maintained; to keep your data up to date it should be regularly cleaned, especially before mailing out marketing materials.

Sending communications using inaccurate consumer data can cost you both money and customers; nobody wants to receive a mailing where their personal information is wrong.
