Which component is responsible for delivering alert emails to end users?

The component responsible for delivering alert emails to end users is the Broadcaster. This functionality is designed to facilitate the automated dissemination of information, such as alerts or notifications, to a targeted audience. In the context of systems like Medallia, Broadcaster plays a crucial role by ensuring that relevant insights and updates reach the users who need them, thereby enhancing communication and responsiveness based on real-time data.

The other components serve different purposes within the system. For instance, Notifier typically manages notifications within the platform but isn't specifically tasked with email delivery. Reporter focuses on generating reports and visualizations from the data collected, which does not directly relate to the delivery of alerts. Distributor may manage the flow of data and resources but does not specifically cover the aspect of alert notifications. This clarity around the functionalities of each component highlights why Broadcaster is the correct choice for delivering alert emails.
