Definition
List freshness score evaluates how current your subscriber engagement is. A fresh list has most subscribers having opened or clicked recently. A stale list has a large percentage of subscribers who have not engaged in months, even if they have not unsubscribed.
Scoring Components
- Recency: How long since each subscriber last opened or clicked
- Signup age: Subscribers who joined years ago may have changed preferences
- Consent age: How long since permission was last confirmed
- Engagement trend: Whether individual engagement is increasing or declining
Why It Matters
A fresh list delivers better deliverability, higher engagement, and more accurate metrics. A stale list drags down your sender reputation and inflates list size with subscribers who will never convert. Regular freshness scoring tells you when it is time for a re-engagement or sunset campaign.
