Overview

When an event is full, interested attendees can submit a waiting list form for a chance to reserve a spot if someone cancels. Organizers can set a reservation limit and use verification to manage entries. The waiting list gives event teams a way to track demand for sold-out events alongside their regular bookings.

When a space opens, the plugin can send a time-limited claim offer to the next person in the queue. If the spot is not claimed, it can pass to the next attendee. Organizers can manage waiting list entries, review queue activity, and send email notifications for reservation offers, confirmations, cancellations, and reminders.

Features

  • Custom waiting list forms: Create waiting list forms for events so interested attendees can submit a request when an event has reached capacity.
  • Reservation verification: Use verification statuses to check waiting list reservations and send attendees messages about verifying or confirming their entries.
  • Reservation limits: Set a limit on the number of reservations allowed on a waiting list to control how many attendees can join the queue.
  • Time-limited spot offers: When a space becomes available, send the next attendee a time-limited offer with a claim link. Unclaimed spaces can pass to the next person in line.
  • Waiting list dashboard: Review queue activity in a dashboard with event pressure details, outcome charts, summary cards, and recent activity.
  • Attendee self-service: Attendees can view and manage their waiting list entries through a front-end app, while organizers manage entries alongside regular bookings.

Best for

  • Modern Events Calendar event organizers
