Nested Email Programs in the Engagement Programs tech details
I’ve read over 100 posts in the community on this topic. The most helpful were Marketo Success Series: Engagement Programs and Engagement Programs Part 3: Technical Deep Dive.
I'm setting up the Nurture with Nested programs for the first time and would really appreciate community's help on the topic.
Here's what's given:
Engagement Program 1 (EP1 for future reference) contains 7 nested default email programs with emails and smart campaigns (let’s call them NP1, NP 2 etc for future reference). Each of the Nested programs contains email asset and the following smart campaigns (you can see them on the image too):
1. Send email
- Track opens
- Track Clicks
- Track replies (we have Drift Email)
- Track unsubscribe
- Exclude people from sending specific content if it was already downloaded before.

The questions I have:
1. Do the smart campaigns within nested program have to be trigger campaigns? Meaning on the Smart list page do I use trigger filter “opens email” or just a filter “Opened Email” (referencing the email from this nested campaign)?
2. In the Exclude smart campaign I filter out the leads that have already downloaded the asset, again I’m not sure if I should use the filter visited webpage/filled form in a specific timeframe or should I use the trigger?
3. In the Exclude smart campaign I followed the general advice here in the community to create program status Nurture excluded. However what is not clear to me is in the smart campaign flow step should I change the program status to “Nurture Excluded” for the Nested Program (NP1) or for the the whole engagement program (EP1).
4. In the Smart Campaigns in each nested program do I change the program status to Opened, clicked, unsubscribed etc for the NP1 or for the EP1?
Thank you in advance for the support!
