Lately we've discovered that we have programs stealing acquisition credit from other programs. For example, someone first comes in to our database through a list purchase and then at some point later in time registers for a webinar, the webinar will change the acquisition program and channel.
I adjusted the smart list in our Acquisition smart campaigns to include the filter Acquisition Channel is empty. However, this morning I see that someone who had an acq. channel as List Purchase made it through the Acquisition campaign of a webinar program and had it changed. Here's a couple screenshots below:
The person was created in 2017 so the issue is not with the 20 minute window. Appreciate the help!
Can you include the full smart list (including any advanced logic)? Also, you're not including the campaign column in your other screenshot. Is the campaign referencing the smart campaign that you reference here?
What this person did was fill out the form for the first "Fills Out Form" trigger, which is filling out the form on the local LP inside the program. Is there any other info you need?
I would suggest "blocking field updates" to the Acquisition Channel. In that way when the program has first set the Acquisition Channel value, any further updates will not be able to overwrite into the field.
Instructions on how to set this up is: Block Updates to a Field - Marketo Docs - Product Documentation
Hope this helps
