I see that Tracking Extracts allow you to "Include Test Sends" but the data doesn't make it possible to distinguish test sends vs. non-test sends. Am I missing something? Will I have to include this as part of me send logging?
Well, because the Tracking Data Extract documentation is such a clusterbleep, who knows?
If you use the System Data Views, there's a flag that distinguishes test sends, but from what I can tell, they're either included or not based on the checkbox.
