How can “too many automations” cause fatigue-based filtering?

Automation fatigue problems:

How it happens:

Multiple automation sequences running

Overlapping triggers sending too many emails

Recipients receiving many emails daily

Recipient impact:

Stop opening (engagement drops)

Unsubscribe or complain

Negative engagement signals accumulate

Provider response:

Low engagement triggers filtering

Complaint patterns add to distrust

May affect all your mail, not just automations

Prevention:

Frequency caps across all automations

Coordination between marketing and lifecycle

Monitor per-recipient message volume

Quality over quantity

Overwhelming customers with too many shipments causes them to refuse future deliveries.
