Here's an example of one of the streams in an EP that consists of four emails:
While the EP logic will ensure no lead receives an email if a lead is already a member of a program, we still need to include additional logic in the smart campaign to also filter out users who have downloaded the content as part of another Marketo program outside of the EP. Let's take the "CIMO Report" as an example. We have a separate program that tracks users who download this report from our
website. Therefore we include this filter in the smart campaign that sends out this email within the EP:
Just know that this will only work for KNOWN users. So unless you're able to identify a cookied user who has downloaded your free content, there's no way to prevent them from receiving an email in an EP that relates to that content.
