# Messaging components

Messaging components send notifications, events, or messages from an orchestration pipeline to external systems, such as message queues, pub/sub topics, monitoring platforms, or email.

***

## Use cases

Messaging components are useful for connecting a pipeline to event-driven systems, keeping people informed of pipeline outcomes, or triggering work in other applications once a pipeline reaches a certain stage. Use messaging components to:

* Notify a team or stakeholder by email when a pipeline succeeds, fails, or reaches a specific point.
* Publish a message to a queue or topic so another system can pick up work triggered by the pipeline.
* Post an event to a webhook to trigger a downstream workflow or integration.
* Publish metrics or custom events to a monitoring platform.
