Formstork

USE CASE

The backend for your RSVP form

Formstork is the backend for your RSVP form, so there is no server to build or host. Point any HTML form at it, or share a hosted form page, and every reply lands in a searchable dashboard, gets emailed to you, and joins a guest list you can filter and export any time.

How it works

Formstork receives the POST from your RSVP form on any host and stores every reply in a searchable, taggable dashboard while emailing you each one, with the guest's email set as the reply-to so you can respond with directions or details. Filter the dashboard by your attending field to see exactly who is coming, and export the whole list to CSV or JSON for your caterer, venue, or seating chart. A rules engine can read that same field to redirect a 'yes' and a 'no' to different thank-you pages, connect Google Sheets or Airtable to share a live guest list, and on paid plans an autoresponder confirms each RSVP the moment it arrives.

Your guest list and headcount, live

Every reply is stored in a searchable, taggable dashboard, so you can filter to the yeses for an exact headcount and see who is still to reply. Export the whole list to CSV or JSON at any time to hand your caterer or venue a final count.

Handle a yes and a no differently

The rules engine reads your attending field and can redirect a 'yes' to an event-details page and a 'no' to a short thank-you, or route certain replies to a different recipient. Your guest list stays organized without any manual sorting.

Confirm every guest, follow up by reply

On paid plans, an autoresponder sends each guest an instant 'we have your RSVP' confirmation. Because the guest's email is set as the reply-to on every notification, you can reply straight from your inbox with directions, parking, or a schedule.

Set it up

  1. 1Add your RSVP form as plain HTML with fields like name, email, and an attending choice, or build one in the no-code form builder if you do not have a site.
  2. 2Point the form's action at https://api.formstork.com/submit and add your access key as a hidden access_key field (or share the short /f/ACCESS_KEY URL).
  3. 3Submit once to test. Each reply lands in your dashboard and your inbox, with the guest's email set as the reply-to.
  4. 4Optional: connect Google Sheets or Airtable for a live guest list, add a rule to redirect regrets, or turn on an autoresponder to confirm each RSVP (paid plans).

Frequently asked questions

How do I collect RSVP replies without a server?

Point your HTML RSVP form at Formstork and add your access key as a hidden field, or build the form in the no-code builder and share its hosted page. Formstork is the backend: it stores every reply, emails you, and shows them in a searchable dashboard. There is no server to build or host.

Can I get a headcount and share the list with my caterer?

Yes. Filter the dashboard by your attending field to get an exact yes count, then export the full guest list to CSV or JSON for your caterer, venue, or seating chart. You can also connect Google Sheets or Airtable so the list updates live as replies come in.

Is it free?

Yes. The free plan covers 250 submissions a month with a full dashboard, email delivery, spam filtering, integrations, and 90-day retention, no credit card. Paid plans add more volume, forever retention, and autoresponders to confirm each RSVP automatically.
