Setup Class Notifications
Class participants should get a message when they book or join the waitlist, when a waitlist spot opens, when a class moves or is cancelled, and a reminder before it starts. Class messages are sent with automation rules on the Class Participant Updates trigger, which runs whenever a participant is added, updated or cancelled.
An approved WhatsApp template for each message (or use email). See WhatsApp Message Templates.
Class booking confirmation
- Go to Engage > Automations, click Add Rule and then Create rule from scratch.
- Choose the trigger Class Participant Updates.
- Click Add Condition and set Class Participant Status equals Booked.
- Add the action send a WhatsApp template message (or Send Email) and pick your template, for example one named
class_booking_confirmed. - Fill the parameters. Type # to insert variables such as
{{class.className}},{{class.date}}and{{class.time}}. - Click Save, then add a test participant to a class.

Because a waitlisted participant who gets a spot becomes Booked, this rule also tells them their spot is confirmed.
Other class messages
Create one rule per message with a different Class Participant Status:
| Status | Message |
|---|---|
| Waitlisted | "You're on the waitlist; we'll let you know if a spot opens." |
| Rescheduled | New date and time of the class. |
| Cancelled | Cancellation notice, with a link to book another class. |
| Visited | Thank you, review request or follow-up. |
| No-Show | "We missed you" with a rebooking link. |
Class reminder
In your confirmation rule, add another action, click Add wait & Schedule time and choose how long before class to send it, for example 2 hours before. Use the same pattern with after class for follow-ups.
