This allows you to automatically communicate with people you have have Attended your event.
On the attended workflow you might want to send an email to thank the student for attending and send them a link to a post-event survey that you've set up in the Surveys app.
The Attended and Not Attended workflows are triggered after the event attendees have been confirmed by a Super User in the CRM.
The exception to this is the 'On the day' bookings in open days. On the day bookings are added to the Attended workflow immediately after being added to the system.
