Default Control Group Selection in 8.6 CDH
Is there a default control group selection as part of batch processing? I have configured E2E NBA designer and schedule also ran. As per the scheduled batch run there should be 5 emails but I have been receiving only 3 emails of out of 5. The IH has entry for 5 emails. I remember in 8.4 version there was a strategy which used to put 2% customers in control group. Is there a way to disable this default selection and send out all comms?
Have verified the email address for all sample customers and the offer flows are fine.
