“I liked how easy it was to set up the waitlist page using already-made templates, but also adjusting colors, fonts, and other parts of the landing page. I also value the functionality of statistics.”

How to integrate
Follow these Squarespace-specific instructions
Get your Waitlister form endpoint
Sign into Waitlister → go to Overview → copy your waitlist key. Your form submission URL is:
https://waitlister.me/s/YOUR_WAITLIST_KEY
New to Waitlister? Learn how to create your first waitlist.
Add a Form Block to your page
Edit your Squarespace page → click the + button → search for "Form" → add a Form Block. Squarespace will add a basic form with fields.
Customize your form fields
Click Edit on your form. Keep the email field (required). Add a name field if you want. Remove any fields you don't need. Customize the button text to something like "Join Waitlist".
Configure form storage and actions
In the form editor, go to the Storage tab. Turn OFF "Store form submissions" (Waitlister will handle this). This keeps your Squarespace clean.
Set up form submission
Still in form settings, go to the Advanced tab. Enable "Post-Submit Action" and select "Redirect to URL".
However, we need to use a workaround since Squarespace doesn't support custom form actions directly. Add this Code Block ABOVE your form:
<script>
document.addEventListener("DOMContentLoaded", function() {
const form = document.querySelector(".sqs-block-form");
if (form) {
form.setAttribute("action", "https://waitlister.me/s/YOUR_WAITLIST_KEY");
form.setAttribute("method", "POST");
}
});
</script>Set field names for Waitlister
For each form field, click on it → go to Field Options → set the field name:
- Email field:
email - Name field:
name - Any other fields: use custom names

Whitelist your Squarespace domain
In Waitlister → Settings → Configure → Whitelisted domains, add your site URL:
Squarespace domain: yoursite.squarespace.com
Custom domain: yourdomain.com
Add both if you have a custom domainTest your form thoroughly
Save your page and test the form. Submit a test signup with your own email. Check that it appears in your Waitlister dashboard.
Test on mobile devices too. Track performance with built-in analytics.

Quick fixes for Squarespace-specific problems
Make sure you added the Waitlister script to Code Injection (Settings → Advanced → Code Injection → Footer).
Then verify the Code Block has the correct embed code with your waitlist key. Save the page and refresh your browser.
Check that the script in Code Injection is saved properly. Clear your browser cache (Cmd/Ctrl + Shift + R).
If using the embed method, the form should appear fully styled. If not, the script may not be loading.
Verify your domain is whitelisted in Waitlister settings under Configure. Include both your .squarespace.com domain AND any custom domain.
Check that your waitlist key in the code is correct with no extra spaces.
Make sure you're using a CODE Block, not a TEXT or MARKDOWN block. Code Blocks have a specific icon.
Also ensure you pasted the code in the HTML/code editor, not the visual editor.
Adjust the data-height value in your embed code. Try different heights until it fits perfectly. Start at 450px and adjust up or down.
Squarespace Code Blocks align based on your page layout. Wrap your form in a centered div or use Squarespace's layout options to center the Code Block container.
Squarespace makes custom form actions difficult. The embed method is much more reliable for Squarespace.
We strongly recommend using the embed method instead of the form action method for Squarespace sites.
Check if you've hidden the Code Block on mobile devices. In Squarespace editor, select the Code Block → click the display icon → make sure it's visible on all device sizes.
You can have multiple waitlist forms on different pages without conflicts. Just use the same embed code on each page.
If you need different forms, create separate waitlists in Waitlister with different keys.
