How do you separate cold from warm audiences to rebuild?

Separating audiences for recovery requires engagement-based segmentation:

Hot audiences engaged within the last 30 days. These recipients recently opened, clicked, or replied. They are most likely to generate positive signals during recovery.

Warm audiences engaged within 30-90 days. These recipients showed interest recently but may be cooling. They are moderately safe for recovery sending.

Cold audiences have not engaged in 90+ days. These recipients pose the highest risk. They may have lost interest, changed addresses, or become spamtraps.

Recovery should start with hot audiences only. Add warm segments as reputation stabilizes. Cold audiences require separate re-engagement campaigns with strict monitoring.

Rebuild by delivering to your most welcoming ports first. Prove your cargo quality to friendly merchants before approaching those who turned you away.
