You don’t need that for the email notification flow with Prefect Cloud. If you’re sending emails from your own email services in Prefect flows that is something you can explore with that library. If you’re using a self-hosted Prefect server instance instead of Cloud and want to use a notification (as there are no automations) - see these docs.
