Waitlist Forms and Questions
This guide explains how to add custom questions to a waitlist signup form. The default form only asks for an email address; custom questions let you collect extra information from signups.
Where to find this
| Page | Path |
|---|---|
| Waitlists list | Dashboard → Contacts → Waitlists |
| Waitlist detail / editor | Dashboard → Contacts → Waitlists → [Your waitlist] |
| Public waitlist page | your public waitlist page |
How custom questions work
The waitlist form uses a set of form fields. Each item defines one question. Questions are shown on the public signup page in the order you add them.
Email is always collected by default and does not need to be included in the form fields list.
Add a custom question
- Open the waitlist detail page at Dashboard → Contacts → Waitlists → [Your waitlist].
- Find the Custom questions section.
- Add a new question with the fields below.
- Save the waitlist.

| Label | Text shown to the user above the input. | Yes |

What happens to answers
When someone submits the form:
- The signup is validated.
- Answers are stored with the contact record.
- You can view answers on the contact detail page or export contact data.
Form design tips
- Keep the form short. Each extra question reduces completion rates.
- Make only the most important questions required.
- Use Select or Radio when you have a fixed set of answers.
- Use Checkbox when users may choose more than one option.
Common issues
- Form not saving. Check that each question key is unique.
- Question not showing. Verify the question type is supported and spelled correctly.
- Options missing. Select, Radio, and Checkbox questions must include a list of options.
- Form feels too long. Remove optional questions that do not change your follow-up strategy.
