Hi Klaviyo Community,

I’m looking to run a holdout test specifically for our Abandon Cart flow to better understand the incremental impact of that series. I see that the Global Holdout Testing feature allows you to apply a certain percentage holdout and then exclude any number of flows from the holdout.

My question is:
If I want the holdout to apply only to the Abandon Cart flow, would the correct approach be to create a global holdout test and exclude every single flow except the Abandon Cart flow—essentially making Abandon Cart the only flow subject to holdout testing?

Or is there a better or more precise method to isolate holdout testing for just one flow?

Would love to hear how others have approached this—thanks in advance!
