Data appending is the process of matching a prospect on your “house list” to a national consumer database. When a match is found, the supplemental information is added to your database. Appended information can include hundreds of data points, such as:
By adding this information to your house list, you fill the gaps in your database as well as develop a much deeper understanding of who your clients (or donors) are.
