Anyone know how I can pull a list of smart lists that are using a specific filter? Similar to the way that I use campaign inspector to pull a list of where the filter is being used in campaigns?
If the filter is for a person or company attribute like "Industry", you can navigate to Admin > Field Management and then find the field in the right side panel and click it. You will then see a list "Field Used By" that lists all assets using that field. However, if you are looking for activity filters like "Clicked Link in Email", I do not believe it is possible to know which assets may be referencing that filter.
