Confirm who's still coming

Ask registrants to confirm before the event and let silence free up seats, then use predicted turnout and the cap calculator to set a capacity that fills the room.

Ask people to confirm before the event

You decide whether to ask and when. The RSVP Confirmation section of the event's edit form does the rest. Automatically send a Confirm RSVP request emails every confirmed registration once the Send lead time arrives (hours before the event). Expires sets the reply deadline, also in hours before the event, and has to be shorter than the lead time. If no response by the deadline either cancels the RSVP, which frees the seat for the waitlist, or does nothing. People who confirm keep their spot either way. In some communities the NeighborlyEvents team reviews those cancellations before they go through, so a non-responder keeps their seat (and can still confirm) until the review is done; if one is held longer than you expect, email [email protected].

Ask people to confirm before the event

Leave a gap between the deadline and the start, so people promoted off the waitlist have time to plan.

Tell people up front that you'll ask

Require a registration acknowledgement adds a required checkbox to the registration form, so everyone agrees when they sign up that they'll need to confirm later. It appears with your custom questions, and its wording keeps up with the Expires time. Untick it to take it off the form.

Tell people up front that you'll ask

If the deadline cancels non-responders, turn this on. Nobody likes losing a seat over an email they didn't expect.

Send one right now

Send Now, in the same section, sends the confirmation request to everyone currently registered straight away, using your saved settings (so save any changes first). Once automatic sending is on, a Send RSVP Confirmation button also appears on the Registrations tab. Compose Confirmation Message opens the message composer with the confirmation already attached, for your own wording or a narrower group, and Send Test Email shows you what people will get. A send only goes out while the reply deadline is still ahead.

Send one right now

If your community needs approval for mass emails, the request waits for an admin and the confirmation message tells you so.

See who answered

The RSVP Confirmation filter on the event's Registrations tab sorts registrations by where they stand: Not asked yet, Awaiting reply, Confirmed, Declined, or Expired. Use Awaiting reply for a last nudge in Messages, and Declined or Expired to see whose seats opened up. Anyone who declines frees their seat right away, so with Auto-promote from waitlist on, the waitlist moves without you.

Check predicted turnout

Predicted, beside RSVPs on the event's Overview tab, estimates how many people will really come, and the Predicted turnout card below explains it: confirmed seats, how many of them are expected, expected walk-ins, and a likely range that turnout lands inside 8 times out of 10. How we calculated this shows each step. It learns only from past events where people were checked in, so check-in at your events is what makes it work. Once the event is over, it shows who actually came beside the prediction. Each registrant's chance, inside the card, and the Likely column on the Registrations tab give each party's chance of coming.

Check predicted turnout

The individual chances are for organizers only. They're never shown to anyone and never decide who gets in.

Let the cap calculator pick the capacity

Since not everyone who registers comes, the right capacity is often more than the room holds. Not sure what to set? Use the cap calculator, under Event capacity on the edit form, takes Venue holds (the most people who fit), People you want there (your goal), or both, and Overflow risk you'll accept (10% to start). Suggest a cap gives you a number and why. Use this cap puts it in the capacity field, and nothing changes until you save. The same calculator is in the Predicted turnout card on the Overview tab.

Let the cap calculator pick the capacity

Keep the overflow risk low for a room with a fire-code limit. Raise it for a park, where a few extra people do no harm.
