By default, a notification email is sent to the site administrator. However, in a lot of cases, the site administrator is not the person in charge of handling form submissions.
In the Registration Form template, we created as well a Volunteer confirmation.
You may need different type of confirmations depending of your events / activities…
As for the confirmation, it is possible to insert data submitted by the user in the email, as well as use conditional logic to decide when to use this email notification.
To have more information, please read Gravity Forms’ documentation.
