Contact form for Squarespace
Contact form for Squarespace on any plan.
Paste one HTML form into a Squarespace Code Block and every message lands in your dashboard and inbox — no Business-plan upgrade, even on the free trial.
- 500 free / mo
- Any plan works
- No Business plan
No Business plan needed
Custom fields, file uploads, and webhooks work on every Squarespace tier — even the 14-day free trial — because the form posts straight to splitforms.
Spam filtered server-side
A honeypot and load-time trap ship in the code, then splitforms rate-limits (6/min, 20 per 15 min) and content-scores every submission — most sites never turn on reCAPTCHA.
Route submissions anywhere
From Starter, forward each message to Slack, Notion, Google Sheets, Airtable, or a signed webhook — nothing to configure on the Squarespace side.
Copy-paste ready
Your Squarespace contact form, ready to paste.
Drop this into a Squarespace Code Block set to HTML and replace YOUR_ACCESS_KEY. That's the whole integration — the form never talks to Squarespace's servers, so it works the same on every plan, even the free trial.

How to add a contact form to Squarespace.
The Code Block method takes about five minutes and needs no plan upgrade. For the full walkthrough — Code Injection fallback, theme styling, and troubleshooting — read how to add a custom contact form to Squarespace.
Open the section in the Squarespace editor
Go to the page where you want the form — Contact, About, footer, wherever — and click Edit on that section.
Add a Code Block
Hover between two existing blocks until you see the blue insertion line, click the + icon, search "Code," and add a Code Block.
Set the block to HTML
Make sure the dropdown in the Code Block editor reads HTML, not Markdown, then paste the form code below and replace YOUR_ACCESS_KEY.
Apply and Save
Click Apply in the Code Block, then Save at the top of the Squarespace editor.
Publish and test
Publish the page and submit a real test message. It should land in your splitforms dashboard and inbox within seconds — email notifications are free on every plan.
No Business plan
Why the Squarespace Form Block isn't enough.
The native Form Block is fine for a name, email, and message on any plan. But custom fields beyond the basics, file uploads, and routing submissions anywhere other than your inbox all sit behind the Business plan. Embedding a splitforms form in a Code Block skips all of that — the dropdown field, the file input, and the webhook work the same on the cheapest Squarespace plan as the most expensive one.
- Custom fields and file uploads on every tier, including the trial
- Signed webhooks to Slack, Notion, Sheets, or your own server
- The form posts to splitforms, not Squarespace, so plan tier never matters
Spam filtered
How to stop spam on a Squarespace contact form.
You usually don't have to add anything. The embedded form ships with a honeypot and a load-time trap, and splitforms rate-limits and content-scores every submission server-side — so most Squarespace sites never turn on reCAPTCHA. If yours still gets hit, enable reCAPTCHA v2 with your own site key, or route clean submissions on through the integrations you connect.
- Honeypot + load-time trap ship in the form code
- Rate-limited 6/min, 20 per 15 min, and content-scored server-side
- Optional reCAPTCHA v2 with your own site key from the dashboard

Testimonials
Loved by developers shipping at every scale.
40 quotes on record — from indie hacks to agency migrations.
“I replaced a Lambda + DynamoDB + SES contact form with six lines of HTML. It took eleven minutes, and the dashboard is better than what I was going to build.”
“We migrated 14 client sites off Formspree in a single weekend. The price is a third of what we paid, the API is more honest, and the spam filter actually works.”
“The webhook payload is signed, idempotent, and well-shaped. It reads like code from a competent team, not a CRUD app held together with duct tape.”
“I stopped reaching for Typeform on small marketing sites. splitforms covers 90% of the use case at none of the bloat.”
“I onboarded our whole agency in an afternoon. The MCP integration meant Cursor literally dropped the form straight into our client repos for us.”
“The free plan gave me 500 submissions before I paid a cent, and Pro is five dollars a month. I've spent more on coffee deciding which backend to use.”
“Spam went from forty junk entries a day to zero, with no reCAPTCHA puzzle ruining the form. The honeypot and time-trap just quietly do their job.”
“Point the form action at one endpoint and you're done. No SDK, no client library, no build step. This is how a form backend should feel.”
“Leads land in Slack the second someone submits, and a copy goes to Google Sheets for the sales team. I wired both up in under ten minutes.”
“I run a static Hugo site on a five-dollar VPS. splitforms gave it a real contact form without me standing up a single server.”
Questions
Squarespace contact form questions.
View all FAQsCan I add a custom contact form to Squarespace without the Business plan?
Yes. Because a splitforms form posts directly to splitforms.com/api/submit, your Squarespace plan tier never comes into it — the same embed works on the Personal plan, the Business plan, and even the 14-day free trial. You only need Squarespace's Business plan if you rely on its native Form Block for advanced fields.
Does Squarespace have a built-in contact form?
Yes — the Form Block. It handles a basic name, email, and message on any plan, so a simple contact page may not need anything more. Its more advanced capabilities, though, are reserved for the Business plan — which is exactly what an embedded splitforms form gives you on every tier.
Why isn't my Squarespace contact form sending emails?
If you're using splitforms and the dashboard shows the submission but no email arrives, check your spam folder first — that's the most common cause. If it's not there, double-check the access key in your form HTML matches the one in your dashboard exactly (a stray space breaks it). Email notifications are free on every plan, so there's no setting to unlock.
How much does a Squarespace contact form backend cost?
With splitforms, the Free plan covers 500 submissions/month, unlimited forms, spam filtering, and email notifications — no credit card. Pro is $5/month for 5,000 submissions plus CSV/XML/PDF export, webhooks, and an auto-responder. Pro is $5/month for 5,000 submissions with CC/BCC and priority support.
How do I stop spam on my Squarespace contact form?
You usually don't have to add anything. The embedded form ships with a honeypot and a load-time trap, and splitforms rate-limits and content-scores every submission server-side, so most Squarespace sites never turn on reCAPTCHA. If yours still gets hit, enable reCAPTCHA v2 with your own site key from the dashboard.
Can I send Squarespace form submissions to Slack, Notion, or Google Sheets?
Yes, from Pro ($5/mo) up. In your dashboard you connect Google Sheets, Notion, Airtable, Slack, Discord, Telegram, WhatsApp, or Mailchimp with one click — nothing to configure on the Squarespace side. Prefer your own endpoint? Add a signed webhook; the exact delivery contract is covered in the routing section above and the webhook docs.
Will the form match my Squarespace site's design?
Yes, if you don't hardcode fonts or colors. Squarespace wraps Code Blocks in the surrounding section's typography, so a plain, unstyled input inherits your theme's body font automatically. Add a scoped class like .sf-form around the markup if you want to nudge corners, spacing, or the button color without it leaking into other blocks.
What if my Squarespace Code Block strips the <script> tag?
Older Squarespace 7.0 templates occasionally strip <script> tags from a Code Block. If the timestamp field stays empty after saving, move that one script line to Settings → Advanced → Code Injection (Page Footer) instead. The form still works without it — the honeypot alone catches most spam.
How are Squarespace contact form webhooks delivered?
From Pro ($5/mo) you can point a signed webhook at Slack, Discord, Telegram, or WhatsApp, or turn each message into a Google Sheets row, Notion page, or Airtable record. Webhooks are signed with HMAC-SHA256 (a sha256= prefix on the signature header) and delivered with an 8-second timeout, plus one automatic retry when the endpoint times out or returns a 5xx — respond quickly and offload slow work.
Where can I get help setting up my Squarespace form?
Still stuck? Email [email protected] or read the splitforms docs for the full request contract, including file uploads and rate limits.
