How can misinterpretation cause accidental suppression?

Accidental suppression removes valid addresses through misclassification:

Common causes:

Ambiguous codes: Generic errors classified as hard bounces. Temporary as permanent: Transient issues treated as final. Auto-reply confusion: Vacation messages as bounces. Provider quirks: Non-standard responses misread.

High-risk scenarios:

New bounce patterns not in dictionary. Provider changes error format. Bulk classification without review. Aggressive suppression thresholds.

Prevention strategies:

Conservative defaults: Soft bounce until proven hard. Threshold requirements: Multiple failures before suppression. Review queues: Human check on ambiguous cases. Monitoring: Alert on unusual suppression rates.

Recovery:

Maintain suppression audit trail. Allow manual unsuppression. Re-engagement campaigns for mistaken suppressions.

Accidental suppression is friendly fire. Build safeguards to protect your own subscribers.
