Question

Mahesh B · Accepted Answer

When a DLQ is set for an SNS subscription, messages that fail to deliver after several retry attempts are sent to the DLQ. This enables you to handle and analyze undeliverable messages separately, improving the reliability and monitoring of your messaging system.
