Add new list subscribers to a 3-day engagement segment

New list subscribers arrive untagged, causing onboarding emails to miss intended recipients. Keep subscribers in the three-day engagement segment so campaigns begin targeting them within minutes.

Overview

When subscribers join unsegmented, onboarding series miss those early engagement windows and campaign performance suffers. This flow auto-assigns new subscribers to the three-day engagement segment so campaign managers can start targeted nurture within minutes, keeping welcome and onboarding timing precise.
