Definition
Subscriber fatigue sets in when the perceived cost of reading your emails outweighs the perceived value. Signs include declining open rates despite consistent send frequency, increasing unsubscribe rates after specific campaigns, rising spam complaints, and longer gaps between a subscriber's last engagement and their unsubscribe. Prevention strategies include offering frequency preferences at sign-up, segmenting by engagement level, monitoring the fatigue index, and periodically removing inactive subscribers.
