What’s the impact of automation fatigue on metrics?

Automation fatigue emerges when recipients receive too many automated messages:

Symptoms: Declining open rates over time despite consistent triggers. Increasing unsubscribe rates from automated flows. Lower click and conversion rates in later sequence emails. Complaints about receiving too many emails.

Causes: Multiple automations targeting the same recipients. Long sequences with too many emails. Triggers firing too frequently for the same behavior. Lack of coordination across automation programs.

Measurement: Track engagement trends over time. Segment analysis by number of automations received. Monitor per-recipient email frequency.

Mitigation: Global frequency caps across all automations. Priority rules to prevent automation stacking. Engagement-based suppression for declining responders. Regular review of automation necessity.

Each automation seems reasonable individually. Fatigue emerges from the cumulative effect on recipients.
