Monitoring certain key metrics can help identify reader fatigue:
Open Rates: A consistent drop in open rates may indicate that subscribers are losing interest. Click-Through Rates (CTR): A decline in CTR suggests that your content is not engaging enough. Unsubscribe Rates: A spike in unsubscribes is a clear indicator of reader fatigue. Spam Complaints: An increase in spam complaints indicates that your emails are not well-received. Engagement Time: Reduced time spent engaging with your emails can be a sign of fatigue.
