Contact Form for Notion Site

Notion has no native contact form for published sites — the closest built-in option is a database "Form view," which writes rows into Notion but sends no email and filters no spam. The fix: publish through Super.so, Potion.so, or Feather, then paste a small HTML form that POSTs to https://splitforms.com/api/submit with your access key. splitforms handles email delivery, spam filtering, and dashboard storage — free for up to 500 submissions a month.

How to Add a Form to a Notion Site

1. Get your free access key at splitforms.com/login — no credit card required.
2. In your Notion site builder — Super.so's HTML Embed, Potion.so's Custom Code, or Feather's embed block — add a new code element.
3. Paste the form HTML below and replace YOUR_ACCESS_KEY with your key.
4. Optional: add a redirect hidden field pointing at your own thank-you page instead of splitforms's default one.
5. Publish, then submit a test message — it should land in your inbox and the splitforms dashboard within seconds.

<form action="https://splitforms.com/api/submit" method="POST">
  <input type="hidden" name="access_key" value="YOUR_ACCESS_KEY">

  <label>Name</label>
  <input type="text" name="name" required>

  <label>Email</label>
  <input type="email" name="email" required>

  <label>Message</label>
  <textarea name="message" rows="4" required></textarea>

  <!-- Honeypot: bots fill this field, real visitors never see it -->
  <input type="checkbox" name="botcheck" style="display:none" tabindex="-1" autocomplete="off">

  <!-- Time-trap: rejects submissions sent in under 2 seconds -->
  <input type="hidden" name="form_loaded_at" value="">
  <script>document.currentScript.previousElementSibling.value = Date.now();</script>

  <button type="submit">Send</button>
</form>

Full field reference — subject, redirect, replyto — is in the docs.

Where to Paste It: Super.so, Potion.so, or Feather

Notion itself can't render a code block as live HTML, so the form above goes into whichever publishing layer sits on top of your Notion workspace:

• Super.so — paste it into a page-level HTML Embed, or add it once under Code Injection → Head to run it site-wide.
• Potion.so — add a Notion code block set to html, then turn on "Render HTML in code blocks" in your site settings.
• Feather — a narrower embed surface (built for blogs and newsletters), but a raw HTML block still accepts the form.

Screenshots, matching CSS for Notion's default look, and per-builder troubleshooting are in the step-by-step Notion form guide →.

Stopping Spam on a Public Notion Form

A form embedded in a published Notion site is public HTML, so it will attract bots. The snippet above already carries two layers: a botcheck honeypot field bots fill in but human visitors never see, and a form_loaded_at time-trap that rejects anything submitted in under two seconds. splitforms also runs server-side content filtering on every submission, and you can lock the form to your domain with allowed origins or add reCAPTCHA v2 if you need an extra layer.

Send Submissions From Any Form Into a Notion Database

This runs the other direction: instead of adding a form to a Notion site, you can route submissions from any splitforms form — Notion-hosted or not — straight into a Notion database. On Starter ($1/mo) and above, connect the native Notion integration (Dashboard → Integrations → Notion) and every new submission becomes a database page automatically, no relay server required.
