A webinar registration form that tells you who is coming

Updated 2026-10-30

You booked the slot and picked the topic. Now you need to know who will join and what they want to hear. A sign up page that only takes an email tells you very little. I would ask a few more questions and still keep it quick.

What do I learn about each attendee?

Their role, company size and how well they know the topic. That lets you pitch the session at the right level. A free text box collects a question for the host. The time zone shows whether the recording matters more than the live call.

How do people sign up?

They open the link and answer. Or they ask their own AI to do it. It might ask "What is your work email?" Then "What would you like the host to cover?" Then "Will you watch live or catch the recording?" It shows the answers and sends them only after a yes. Learn more about agent-fillable forms.

What happens after sign up?

Nothing automatic. The form does not email attendees or send reminders. You export the CSV and send the join link yourself. One tick box records whether the host may email the recording afterwards.

Where else could I use it?

A product demo, a customer training or a Q and A with an expert. See forms for SaaS and startups and forms for events. Builders can join a hackathon registration form next. For in-person practice, use a workshop registration form. For staff courses, try a training registration form.

Questions

Does the form send the webinar link to attendees?

No. The form sends nothing to the person who fills it. It collects sign ups, and you send the join link or recording to the addresses in the CSV yourself.

How do I use the questions people send in advance?

Read the main_question column before you write your outline. Group similar questions and answer the most common ones first. Sorting by role shows which topics matter to whom.

Can I limit the number of seats?

Yes. Set max_responses to the seat limit of your webinar tool and close_at to a time before the start. The public form then stops taking sign ups.
