Webflow
Webflow contact form that emails you with delivery proof
Webflow renders forms but you may want submissions somewhere you can search, with proof that the alert email arrived. Paste a plain form into an Embed element and Heartdove stores every message first, then tracks the alert to delivery.
Updated 20 October 2026
Add the form to Webflow
Add an Embed element where the form should appear and paste the form into it. Style the inputs with your site CSS. Publish, then submit a test message from the live site.
<!-- Paste into a Webflow Embed element -->
<form action="https://submit.heartdove.com/v1/submit" method="POST">
<input type="hidden" name="access_key" value="YOUR_ACCESS_KEY" />
<label>Email <input type="email" name="email" required /></label>
<label>Message <textarea name="message" required></textarea></label>
<!-- Hidden spam trap: people never see it, bots tick it -->
<input type="checkbox" name="botcheck" tabindex="-1" autocomplete="off" style="display:none" />
<button type="submit">Send message</button>
</form>Webflow publishes to your webflow.io address and to any custom domain. Register each address you publish to.
Register your website address
Heartdove accepts a submission only from the exact website addresses registered on the form, so a copied key cannot be fired from somewhere else. Register every address the form is published on; each form takes up to 10, and registering a www address covers the bare domain too. For a Webflow site that usually means:
https://your-site.webflow.iohttps://www.yourdomain.com
Testing locally? Register your local address, such as http://localhost:3000, as well.
What happens after submit
The message is saved to your inbox before any email is sent, so a failed alert never loses the enquiry. The alert is then tracked step by step and shown on the message:
- CapturedSaved and searchable
- Accepted by providerHanded to the email provider
- DeliveredThe recipient’s mail server accepted it
- BouncedShown with the reason; the address is paused
Over your monthly allowance, submissions are held, visibly, and released automatically. Nothing is billed as overage, and each plan’s hold capacity is on the pricing page. The Free plan includes 500 submissions a month with an instant alert for each.
Spam, without a CAPTCHA
Every form gets the exact origin check, a per-visitor rate limit, the hidden trap field and spam scoring with quarantine. Cloudflare Turnstile can be turned on per form for a human check, and is never required. Read how the layers work.
Questions
Is it safe to put the access key in my page?
Yes. The key is public and only identifies the form; it does not grant access to anything. Submissions are accepted only from the website addresses you register, each visitor is rate limited, and every message is scored for spam before it is stored.
Do I need a CAPTCHA?
No. Every form gets an exact origin check, a per-visitor rate limit, a hidden trap field and spam scoring with quarantine. Cloudflare Turnstile is optional for forms that want a human check.
Can I send visitors to my own thank-you page?
Yes. Add a hidden _redirect field with a full URL on one of the websites registered for the form. JSON requests get a receipt instead of a redirect.
What happens if I go over the free limit?
Submissions above your monthly allowance are held, visibly, for at least seven days and released automatically when your allowance resets. Each plan’s hold capacity is on the pricing page, and there is no overage charge.
