How do you setup a smart list to look for leads created exactly 30 days ago (or 4 weeks)
The smart list above is then used into a batch smart campaign that runs every day and looks at the leads created 4 weeks ago on a rolling window. So each day that passes we look at 30 days in the past and see leads that have been created and send them an email.
You can set up your smart list using two filters.
Filter 1: Person was Created, Date of Activity in past 30 days
Filter 2: Not Person was Created, Date of Activity in past 29 days
