A popular class fills up fast, and tracking who's actually coming across texts and a sign-up sheet doesn't scale past a handful of members. An RSVP block with a capacity cap books a spot with one tap and automatically waitlists anyone past it — right from the class announcement email itself.
For a straightforward capacity-capped sign-up, this covers booking and waitlisting with no separate app. It doesn't handle payments — a paid class still needs a Product block or your existing billing system alongside it.
Capacity does the booking for you
An RSVP block with a capacity set records a one-tap "I'm in," and once that cap is hit, anyone RSVPing after it is automatically marked waitlisted with your own configured message — no manual step to enforce the limit.
Moving someone off the waitlist
RSVP tracks confirmed, waitlisted, and declined counts on the Responses dashboard, but promoting a waitlisted member once a spot frees up isn't automatic — that's a quick reply or a manual follow-up once you see the opening.
Where the class is happening
A Venue block adds the studio or room location with a one-tap directions link — useful for a member new to a specific location.
On the calendar, correctly
An Add-to-calendar block gives a one-click .ics download or Google/Outlook link built from the exact class time, so it's correct in every member's own timezone.
Getting started
Add an RSVP block with the class capacity set, a Venue block for the location, and an Add-to-calendar block for the exact time. Put it on a recurring send if it's a standing weekly class.
