How should senders manage unknown or ambiguous bounces?
Unknown or ambiguous bounces that do not clearly indicate permanent or temporary failure require careful handling. Default to temporary classification initially, retrying appropriately while monitoring patterns.
If ambiguous bounces persist across multiple attempts, escalate to hard bounce treatment. The address is likely undeliverable even if specific reasons are unclear. Continued attempts waste resources and may harm reputation.
Log ambiguous bounces for analysis. Patterns may reveal misclassified bounce types or specific servers with unusual responses. This intelligence helps refine bounce handling over time.
