Notification Component Diagram

This component diagram shows a notification service that can deliver the same event through multiple channels. Application components call the notification API. The API selects templates, checks recipient preferences and passes the result to a channel dispatcher. The dispatcher uses adapter components for email, SMS and push delivery. This separation gives each provider integration a clear boundary and keeps template and consent rules out of application code. The diagram works well for an architecture review because it names the responsibilities that tend to change independently. Add retries, delivery status, rate limiting or in-app messages when those are meaningful parts of the service.
