# Amazon SNS - New message trigger
The New message trigger monitors a message topic and fetches new messages. Workato processes each message as a new job.
429 RESPONSES
Amazon SNS treats a 429
(Too Many Requests) response as a successful delivery when using the New message trigger. Events that receive a 429
response aren't retried or sent to a Dead Letter Queue (DLQ).
Throttle message delivery using the SNS topic's delivery policy to align with Workato's rate limits and prevent event loss. AWS SNS doesn't treat a 429
as a failure and doesn't trigger retries. You can set the throttlePolicy
to maxReceivesPerSecond
to control delivery rate. Refer to the AWS SNS documentation (opens new window) for more information.
