title: Scheduled eventbridge input transformer in serverless framework
body: <p>I have been trying to pass data with event using scheduled eventbridge. But the <a href="https://www.serverless.com/framework/docs/providers/aws/events/event-bridge" rel="nofollow noreferrer">documentation for serverless framework</a> is not very clear.</p>
  <p>Objective: I want to create an email notification system with custom data. So users can turn on notification for lets say 1 week/2 week etc. And They will receive emails with their custom data as long as they keep notifications turned on. If they turn it off, I want to stop sending.</p>
  <p>Please let me know if there is a better approach than scheduled eventbridge to reach my objective. And an example of the scheduled eventdrive in serverless.yml with lambda would be much appreciated.</p>
