How to Add a Waitlist to Your SignUp

Let Interested Participants Know the Moment a Spot Opens Up

Last Updated June 17, 2026

The Notification Waitlist is available on all Premium plans. When spots fill up, interested participants can request an alert — and they will be notified automatically when a spot becomes available.

How to Enable the Waitlist

  1. Go to the Details tab in your Organizer view.
  2. Check the Notification Waitlist checkbox.

How Participants See It

  • Desktop and tablet: Full spots display a "Notify Me When Available" button.
  • Mobile: An orange envelope icon shows with the message "Notify me when new Spots become available."

When Notifications Send

  • About 1 hour after an organizer adds new spots
  • Immediately when a participant cancels and saves their action
  • About 15 minutes when a participant cancels without saving

All waitlisted participants receive the notification at the same time — the first one to sign up gets the spot. Check your Reports tab to see how many participants are on the waitlist for any given spot.
