Email Bot Activity constraints impacting Email Performance Report Metrics
Hello Marketo Nation Community,
I'm an Admin in a client's Marketo subscription where we have been trying to understand a couple of things on how the "filter bot activity" setting impacts Email Performance Reports (EPR).
Just for context, since implementing the Match with IAB List / Match with Proximity Pattern features, the client decided to "Filter Bot Activity" for both options as they wanted as much of this bot activity removed from activity logs as possible. Done. However, we are still seeing some activity that may look bot related such as several clicks in email footer links that the proximity pattern is just not catching. It's expected that it will not be 100% accurate, right? But over time, this will improve with the technology.
But, knowing we are "filtering out all bot activity" at the admin level, why are we seeing a significant impact to "Sent/Delivered" metrics and slight discrepancies within "Opened/Clicked" numbers when we experiment with adding "Is Bot Activity is false" constraints to Opened/Clicked filters within the EPR Smart List? If these activities are being filtered out, then adding such a filter and constraint combinations should have no bearing on the resulting counts, correct?
Here's an example:
A standard EPR where ONLY a Region filter is being used to target AMER - notice the 10k+ counts for Sent/Delivered as well as the counts for Opened:

Now, when adding the 2 Smart List filters: "Opened Email Is ...Is Bot Activity False" or "Clicked Email Is...Is Bot Activity False" as seen below....:

The Sent/Delivered is a quarter of the count it originally was and the Opened has increased by 2 - and yes, the 4 emails listed in the filters are the same 4 emails shown in the report:

Here's another example for the same campaign but for the EMEA region:
Before adding the bot filter constraints:

After adding the same 2 bot filter constraints seen in the example above:

One would think the resulting numbers should be identical if bot activity is being filtered from the activity logs. It would be super helpful if someone could possibly shed some light into why the significant and slight discrepancies we are seeing
Much appreciated.
Thanks!
