How to collect a waitlist on a full form

Forms made since October 10, 2026 have it on by default: when every spot is taken, the form stays open and people fill it in as usual to join the waitlist. Their whole response is saved (answers and picks), no spot is held and nothing is charged. Each person gets (if the form asks for an email) an email saying they're on the waitlist and their place in line, with a link to leave it. Turn it off in Setup, or say "turn off the waitlist" in chat. Older forms keep the switch off by default, and when it's on they ask for a name and email instead.

Steps

1. Open your form and go to the Setup tab.
2. Under Form behaviors, turn on Waitlist when full.
3. Give the form a capacity if it doesn't have one (in chat, for example "max 12 seats"), so it can actually fill up.
4. Once every option is sold out, the button reads "Join the waitlist". On newer forms people fill in the whole form; on older ones they leave a name and email.
5. When a spot opens you get an email. Open Results, find them under Waitlist and press Move in. Tick the spot (the one they waited for is already ticked) and save. We email them that they got a spot, with their change-or-cancel link, and text them too on Pro if they gave a mobile number and agreed to texts. If the form takes cards or PayPal, that email has a Pay button for what they owe (the price they saw when they joined, if you move them into what they waited for); on a Venmo or Zelle form it shows your pay buttons.
6. Or let it run itself (Pro): in Setup, under Who gets a spot that opens, pick Automatic. When someone cancels, you delete a sign-up or you raise the limit, the first person waiting for that option is moved in, and you both get an email. Someone waiting for both days when only Saturday opened gets Saturday and stays first in line for Sunday. It stops for each person once what they're waiting for has started (a week that's begun, say); after that you get the email and decide.

A waitlist for one option (Pro)

On Pro, each option gets its own waitlist as soon as it fills. Say Week 1 of a three-week camp is full: the form shows Full right now: Join the waitlist for Week 1, and a parent can book Weeks 2 and 3 and join Week 1's waitlist in the same sign-up. They pay for what they booked; Week 1 holds no spot and charges nothing until they're moved in. Each full option keeps its own line, so being #1 for Week 1 has nothing to do with Week 3. An add-on that belongs to one option, like aftercare for Week 1, waits with it (ask in chat: "Week 1 aftercare goes with Week 1"). There's nothing to set up. On the free plan the waitlist opens once every option is full.

It stays one sign-up. The parent gets one confirmation that lists what they booked, their place in line for Week 1 and what they'd owe if they get it, and you get one new sign-up email. Results counts the family once and shows "Waiting for Week 1 (#1)" on their row; the Waitlist shows the child's name and that Weeks 2 and 3 are already booked. When you move them in, Week 1 sits under their booking, and their change page shows all three weeks and the total.

On every plan, once everything is full, someone who picks two full weeks joins each week's line. A spot that opens in Week 1 goes to the first person waiting for Week 1, and they stay in line for the other. The one exception: picks priced together (a bundle, or a discount for taking both) stay one wait for all of them, because splitting them would change the price. The person is told that when they join.

On older forms, if only one option fills up first, ask in chat: "add a waitlist for Week 1". That adds a free "Week 1 waitlist" option people can pick to get in line.

With I pick who gets in (the default), nobody is moved in until you press Move in, so you can give a freed-up spot to whoever you choose, in any order. Until you do, the spot is open on the form, so anyone with the link can take it first, and the people waiting are told that when they join. The email names the first person waiting for the option that opened. If someone new takes it first, Move in says who. If you want a spot to go to the first person waiting for it straight away, use Automatic (Pro). Anyone who cancels or leaves the waitlist from their change link shows under Cancelled on Results.
