What notification is received once the deployment has been completed successfully?

The choice of email notification as the correct answer is grounded in the common practices of deployment management systems, including Copado. Once a deployment has been completed successfully, it's standard to receive an email notification to inform the relevant stakeholders, such as developers, project managers, and operations teams. This email serves not only as a confirmation of the successful deployment but also provides important details regarding what was deployed, any changes made, and next steps if necessary.

Email notifications are advantageous in ensuring that the information is documented and can be referenced later, unlike other notification methods that might be transient. Other options like text messages and voice calls, while possible, are less universally used in deployment contexts due to concerns about message overload or the need for an immediate verbal response. System alerts are often seen in real-time systems but might not reach all team members as effectively as email, especially if they are not actively monitoring the system at that moment. In summary, email notifications are a reliable and well-established method for communicating the successful completion of deployments.
