Should I apply any segmentation or filtering to the Orita Grow list?

Generally, no. The Grow model has already identified the most likely converters. If there are any structural or categorical conditions to your campaign (region specific, product specific, subscribers only, etc.) then the segment can be modified accordingly. But if the adjustment has anything to do with engagement or propensity to buy, it’s best to leave the Grow segment as is.

If someone appears on both your audience and Grow, they’ll receive only one email, and lift is calculated based on profiles you wouldn’t have emailed otherwise.
