When you decide to proceed with the data cleansing service then, before importing the cleansed file that is supplied by Blackbaud, User Defined Fields should be added.

These UDFs are used to identify the records cleansed by the service.
See UK MailWise Help File - User Defined Fields for more information on the UDFs to be added.


Important:  
Enter the UDFs exactly as shown in the Help File including capitalization and spacing.
