How Subscriber Engagement Score Works

Understand how Icegram Express calculates 1-to-5 star subscriber engagement scores to identify active readers and inactive contacts.

Monitoring subscriber engagement is critical for email marketing success. Sending emails to inactive contacts hurts your sender reputation and can cause major mailbox providers (like Gmail and Yahoo) to route your messages to the spam folder.

In Icegram Express Max, the Engagement Score feature automatically evaluates each contact’s interaction history over the previous 12 months, ranking them on a 1-to-5 star scale.

How the Engagement Score is Calculated

The engagement score tracks subscriber activity across your campaigns:

Email Opens: How frequently the contact opens your broadcast and post notification emails.
Link Clicks: Whether the subscriber clicks links inside your emails.
Recency: How recently interactions occurred over the trailing 12-month window.

Higher activity results in a higher star rating (up to 5 stars), while completely inactive subscribers drop to 1 star.

Practical Use Cases

Reward VIP Subscribers: Segment contacts with a 4 or 5-star rating to send exclusive discounts, early product access, or thank-you offers.
Re-engagement Campaigns: Identify subscribers with a 1 or 2-star rating and run targeted re-engagement campaigns with win-back subject lines.
List Pruning: Safely unsubscribe or delete persistent non-openers to improve open rates and protect your domain reputation.

How Engagement Scores are Updated

Engagement scores are calculated and refreshed automatically every night at midnight via WordPress cron. No manual calculation or script execution is required, provided your WordPress cron is operating normally.
