Use SuppressionList to filter your leads against large lists of allowed or disallowed values.
For this example we'll be filtering to ensure that each lead's postal code is contained in a list of allowed values. First, create and populate the list in SuppressionList:
Next, edit your LeadConduit flow to add a SuppressionList enhancement step. Select the "SuppressionList Query Item" integration for that step:
Next, map the list name and the flow field to be checked in this step. For this example we'll assume that your List entries are all 5 digit U.S. ZIP codes. However, LeadConduit accepts full 9-digit ZIP+4 postal codes, so you'll need to ensure that you are only querying the 5-digit portion against SuppressionList. Fortunately this is easy to set up. Here's how: When mapping the postal_code field in the SuppressionList query step, click on the ellipsis at the right side of the postal_code line in the select box:
This will display all of the available postal code variants available. Select "ZIP" to specify the 5-digits-only format:
The fully-specified mapping:
To reject leads whose Zip codes are not in the list, add a filter immediately after the SuppressionList Query step:
