Locate the event's specific date / time. Use the Email Event Enrollment button to email an event's attendees.
When you select Email Event Enrollment, Jackrabbit's email editor will open. Enter a subject and your email message, then choose who to send the message to (choose from a combination of Contacts, Students, and/or Staff).
In the Preview window, clear the check box for any recipient you want to take off the message. You can opt to send the message immediately, or you can schedule it to be sent at a later date/time.
