You can find Email notifications in the Workflows section on your admin page. They are helpful for generic scenarios like sending a notification when a new ticket is created or when a ticket is closed.
For configuring customized email notifications based on ticket attributes, such as ticket type, group, source, requester name, and more, use the Automations feature. This is especially useful to route tickets to the right agent or group if your organization is spread across timezones, skills, and languages.
