If you have an active Intent Lead Campaign, you'll want to segment these leads in Pardot using a "Dynamic List."
Dynamic Lists in Pardot use "rules" to automatically add leads to the List. In this sample template, all leads from a Intent Lead Campaign called "2019 Intent Lead Campaign" will be added to a list using the custom BrightTALK property "Campaign Display Name" :
Note: The "Campaign Display Name" value for your Intent Lead Campaign can be found in advance by going to:
2. Clicking "Campaigns" on the left hand side
3. Selecting the "Intent Lead" tab
4. Looking at the values under "Campaign Name."
