As we have learned more about custom properties in Profiles, we have been adding new fields to our customers profiles, but we’d like to pull a list of customers who haven’t had these new fields added yet.
In Lists and Segments there is nothing that I can find to allow us to filter based on CustomFieldXYZ IS NULL or DOES NOT EXIST or even EQUALS BLANK.
How can we pull a list of customers who do not yet have a specific custom profile property?
