Class Calendars handle one-to-many events where multiple people book the same time slot. They fit webinars, workshops, training sessions, group fitness classes, and sports events. Each Class Calendar has a single appointment owner — the trainer or host — and a configurable cap per slot up to 9,999 attendees.

What a Class Booking is

A class booking is a one-to-many calendar designed to host multiple invitees in a single time slot. Common uses:

Webinars and workshops
Training sessions
Group fitness or sports events

Why use Class Calendars

One booking, many attendees — invitees register against one slot, not separate appointments.
Configurable capacity — cap each slot at the number that fits your room, Zoom plan, or class format.
Centralized management — bookings, cancellations, and reschedules live in one calendar view.
Cleaner attendee comms — reminders pull date, time, and location automatically.
Self-serve cancel and reschedule — toggle these on so attendees handle their own changes.

Note on shared calendar links

When you share a Class Booking Calendar link, it always opens to the current month — not the month your class runs. If the class is in a future month, attendees may see "No available time slots" until they navigate forward with the arrow.

Frequently Asked Questions

How do I email every attendee of a class session?

Go to Contacts and filter by the specific class appointment using Advanced Filters or Appointment-based filters. Select the contacts and use the bulk email action. For ongoing communication, save the filter as a Smart List.

Can I cancel or reschedule one attendee without canceling the class?

Yes. In the class appointment, click the options menu next to the contact and choose Cancel or Reschedule for that attendee.

Can attendees cancel or reschedule themselves?

Yes. Enable Allow Cancellation and Allow Reschedule under the Confirmation Tab in your Calendar Settings.

How do I cancel an entire class session?

Open the class appointment from Calendar View or Appointment List View, click the trash icon, and confirm. The session and every registered attendee are removed from that time slot.

What's the maximum class size?

Up to 9,999 attendees per slot, though your meeting platform (Zoom, etc.) or physical venue may impose tighter limits.
