Add your signup form to Webflow.

Which snippet to use

The inline form in a Code Embed element. The iframe embed works there too if you’d rather show the full branded form.

Step by step

1. Copy your inline form. In your Hollerpost dashboard, go to Audience → Signup forms, pick the form you want (or the default page), and click Copy code next to “Inline form for your website.” It looks like this:

   <form method="POST" action="https://utopian-marketing-api.jmiller-580.workers.dev/api/marketing/signup/your-workspace" style="display:flex;gap:8px;max-width:420px">
     <input type="hidden" name="form_id" value="your-form-id">
     <input type="text" name="website" value="" style="display:none" tabindex="-1" autocomplete="off">
     <input type="email" name="email" required placeholder="you@example.com"
       style="flex:1;padding:10px 12px;border:1px solid #ccc;border-radius:8px">
     <button type="submit"
       style="padding:10px 16px;border:0;border-radius:8px;background:#4f46e5;color:#fff;font-weight:600">
       Subscribe</button>
   </form>

   This is a placeholder. Copy yours from Audience → Signup forms in your dashboard.

2. Add a Code Embed. In the Webflow Designer, open the Add panel and drag a Code Embed element onto the canvas where you want the form.
3. Paste your code into the code editor that opens, then Save & Close. Don’t add <html>, <head>, or <body> tags; Webflow warns they break your layout.
4. Publish your site. Custom code takes effect once you publish.
5. Test it on the published site with your own email. You should show up in Audience in your dashboard.

No custom code on your plan? Add a Button or Link Block that points at your signup page link from Audience → Signup forms, “Hosted signup page.”

What happens when someone signs up

They land in your audience with their consent recorded (where they signed up and when), tagged signup-form plus any tags you set on the form. If the form asks for email confirmation, they join once they click the link we send them. With the inline form, the thank-you message opens on your Hollerpost signup page; with the iframe, it shows right inside the box.

If it doesn’t show up

• It works in the Designer but not live, or the other way round. Publish again. Webflow says custom code doesn’t go live until you publish.
• Part of the page looks broken. Check you pasted the whole snippet, from <form to </form>. Webflow suggests checking your opening and closing tags.
• You used Webflow’s own Form block. That’s a different element and sends entries to Webflow. Use a Code Embed with your Hollerpost code.
