+### Retry letter topic
+
+Retry letter topic allows you to store the messages that failed to be consumed and retry consuming them later. With this method, you can custom the interval to retry the delivery of the messages, and subscribers automatically subscribe to the retry letter topic and re-consume it. When the specified maximum number of retries is reached, the unconsumed messages are moved to a [dead letter topic](#dead-letter-topic) for manual processing.
Review comment:
Some minor grammatical errors:
"The retry letter topic allows you to store the messages that failed to be consumed and retry consuming them later. With this method, you can customize the interval at which the messages are redelivered. Consumers on the original topic are automatically subscribed to the retry letter topic as well. Once the maximum number of retries has been reached, the unconsumed messages are moved to a [dead letter topic](#dead-letter-topic) for manual processing."
