Dead Letter Queue Panel Home

Dead letter queues store messages that cannot be correctly consumed.

If a message fails to be consumed, the system will retry sending it. After the maximum number of retries (which is 16 by default and configurable on the client) is reached and the message consumption still fails, the message becomes a dead letter message and is delivered to the dead letter queue that corresponds to the consumer.
