MailExecution

type: "io.kestra.plugin.notifications.mail.MailExecution"

Send an email with the execution information

The message will include a link to the execution page in the UI along with the execution ID, namespace, flow name, the start date, duration and the final status of the execution, and (if failed) the task that led to a failure.

Use this notification task only in a flow that has a Flow trigger, as shown in this example. Don't use this notification task in errors tasks. Instead, for errors tasks, use the MailSend task.
