Using Supplemental Data Sources for Inclusions or Exclusions

When using a supplemental data source for inclusions or exclusions, you must ensure that the following requirements are met:

• The data source must contain a column for email addresses.
• For exclusions, the data extraction key in each selected data source must contain an email address. For more information, see Selecting Key Fields.
• For inclusions, the data source must use the Email_Address_, RIID_, or Customer_ID_field as the data extraction key. For more information, see Selecting Key Fields.
• The data type of the Email_Address field in the supplemental table must be the same as that of the Email_Address_ field in the distribution list. For example, if the Email_Address field in the list is "Text Field (to 500 chars)", the Email_Address_field in the supplemental table data must also be "Text Field (to 500 chars)".
