Paste one HTML snippet into an Embed block and get a styled contact form with email alerts and spam filtering — no Google Form, no Apps Script.
No Google Form, no Apps Script, no add-on. Your Google Sites form posts straight to one hosted endpoint.
Honeypot, a form_loaded_at time-trap, IP rate limiting, and server-side heuristics — plus optional reCAPTCHA v2.
Every submission is emailed to you and saved to a searchable dashboard the moment it lands — free on every plan.
Copy-paste ready
Drop this into Insert → Embed → Embed code, then replace YOUR_ACCESS_KEY with the key from your dashboard. It's self-contained — Google Sites sandboxes embeds, so the snippet carries its own CSS and a fetch()-based submit that shows an in-place thanks message instead of a broken redirect.

</script>Setup
No Apps Script, no Workspace add-on. Copy the snippet, paste it into an Embed block, and publish — the whole thing takes about three minutes. Test on the published URL, not the editor preview.
Create a free splitforms account at splitforms.com/login, copy your access key from the dashboard, and paste it into the form snippet below in place of YOUR_ACCESS_KEY. The Free plan includes 500 submissions total — no credit card.
In the Google Sites editor, click Insert in the right-hand panel, choose Embed, switch to the Embed code tab, paste the snippet, then click Next and Insert. Drag the handles to size the box — it doesn't auto-grow.
Click Publish and send a test message from the live URL (not the editor preview). Every submission is saved to your splitforms dashboard and emailed to you the moment it lands.
Why it's needed
No — the Insert panel's Forms option only embeds a separate Google Form in its own iframe, with Google's fonts, writing responses into Sheets. There's no styleable contact form block. The fix needs no Apps Script: Insert → Embed → Embed code accepts a raw <form> that posts straight to a hosted backend. The same approach works on Notion, Wix, and GitHub Pages.
Where submissions go
Every submission is emailed to you and saved to a searchable dashboard — spam filtered before it ever reaches you. Search, export to CSV, or forward it to your email, Google Sheets, Slack, or Notion on paid plans.
Spam protection
Yes. Google Sites renders Embed-code HTML in a sandboxed frame, but none of splitforms' spam layers depend on the page around the form — they travel with the snippet or run server-side. More in honeypot vs reCAPTCHA.
How SplitForms works
splitforms receives the submission, filters spam, saves it to your dashboard and emails you — then, on paid plans, sends it on to your webhooks and integrations. No backend infrastructure to build.
Point your form to your unique SplitForms endpoint. That's it.
We instantly capture and organize every submission in your inbox.
Send data to email, spreadsheets, CRMs, webhooks, and 7,000+ apps.
No credit card required. Set up in under 60 seconds.
Connect & automate
On paid plans, submissions can also go to Slack, Discord, Google Sheets, Notion, Airtable, Zapier or any signed webhook — and splitforms works on the platforms you build on, from WordPress and Shopify to Next.js. With Stripe connected, your forms can take payments too.

No. The closest thing is Insert → Forms, which only embeds a separate Google Form — Google's styling, hosted in its own iframe, with responses written to Google Sheets or the Forms responses tab. There's no native, styleable contact form block. To get a form that matches your site, paste custom HTML via Insert → Embed → Embed code and point it at a hosted form backend like splitforms.
Open your page in the Google Sites editor, click Insert, choose Embed, switch to the Embed code tab, and paste an HTML form whose action points to https://splitforms.com/api/submit with your free access key in a hidden field. Click Next, then Insert, resize the box, and publish. Accepted submissions are saved to your SplitForms dashboard before owner notification email is attempted; delivery time and inbox placement depend on provider and recipient settings.
Yes. The splitforms Free plan is $0 for 500 submissions total with unlimited forms, spam filtering, a hosted dashboard, and email notifications — free on every plan, no credit card. If you outgrow it, Pro is $5/month for 5,000 submissions a month plus webhooks, 13 integrations, exports, and autoresponders; Annual is $49/year for 15,000 a month.
No. Apps Script is one way to build your own form handler, but it means writing, deploying, and maintaining script code and managing quotas. An HTML form pasted into an Embed block POSTs directly to splitforms' hosted endpoint, which stores the submission, emails you, and filters spam — no script project on your Google account.
Yes. Every spam layer either ships inside the snippet (the honeypot field and the form_loaded_at timestamp) or runs server-side at splitforms (rate limiting and content heuristics), so the embed's iframe sandbox can't weaken any of them. Nothing needs configuring, and optional reCAPTCHA v2 is there if you ever want an extra layer.
That's the sign of a plain redirect: Google Sites loads the destination page inside the embed's small fixed-size frame, so a full-width thank-you page ends up squeezed into that little box. The snippet on this page sidesteps it by showing an in-place thanks message instead of navigating away. If you'd rather redirect, point it at a compact page sized to fit the embed.
Yes, on paid plans (Pro at $5/month and Annual). Connect the native Google Sheets, Slack, Notion, Airtable, Discord, Telegram, or Mailchimp integration from your dashboard — no change to the embed code. Webhooks are also available: signed with HMAC SHA-256, delivered with an 8-second timeout and one automatic retry on a timeout or 5xx, so your endpoint should still respond quickly.
Google Sites' in-editor preview doesn't always run embedded scripts identically to the published page. Always test on the live, published URL in an incognito window. If nothing happens on submit, open the browser console — a typo in the action URL (it should read exactly https://splitforms.com/api/submit) or a stray character in your access key is the usual cause.
