How to Identify Where the “Delete Person” Flow Step Is Used
Issue
How to identify in which campaign the "Delete Person" flow step is used.
Solution
You can identify it by going to "Campaign Inspector" in Marketing Activities.
From there you can filter down by type of Smart Campaign and search "Delete Person" and the resulting list will be Smart Campaigns containing that flow step.
If you do not see the Campaign Inspector, contact Marketo Support to have it enabled.
