Waitlist overview

Let customers join a waitlist when a session or event is full, and notify them when a spot opens.

Quick answer: When a fixed session or one-off event is full, signed-in customers tap Join waitlist on your booking page — no extra form — and get emailed if a spot opens.

    One tap adds them to the queue — no extra form.
  3. Spot opens

    When someone cancels or you free a spot, the next waitlisted customer is notified.

  4. Customer books from the email link

    The notification includes a deep link to book the now-available slot.

What happens next

If the notified customer doesn't book within your settings, Sway can notify the next person after the cooldown period.
