Metrics & Analytics

Engagement Score

An engagement score is a composite metric that combines multiple signals (opens, clicks, replies, forwards) to measure how actively a subscriber interacts with your emails.

What Is Engagement Score?

Rather than looking at individual metrics in isolation, engagement scoring creates a single number that represents a subscriber's overall activity level. A typical engagement scoring model might assign points for different actions: 1 point for an open, 3 points for a click, 5 points for a reply, and 10 points for a forward or share. Points can decay over time so that recent activity is weighted more heavily. Subscribers are then segmented into tiers — highly engaged, moderately engaged, at-risk, and dormant. This tiered view makes it much easier to target the right content and re-engagement strategies to each group.

Why It Matters for Newsletters

Engagement scoring transforms your subscriber list from a simple count into a meaningful picture of list health. It identifies your most valuable subscribers (for premium content or sponsorship targeting), flags at-risk subscribers before they unsubscribe, and helps you prioritise re-engagement efforts where they'll have the most impact.

Best Practices

  1. Define a scoring model that reflects the actions most valuable to your newsletter
  2. Apply time decay so that recent engagement counts more than past activity
  3. Segment subscribers into engagement tiers for targeted communication
  4. Review and adjust your scoring model quarterly based on actual behaviour patterns
  5. Use engagement scores to clean your list — suppress chronically dormant subscribers
