Jekyll & GitHub Pages contact form without a backend

GitHub Pages can't run server code, so Jekyll sites need an external form endpoint.

_includes/contact.html

<form action="https://forms.elimbi.com/submit" method="POST">
  <input type="hidden" name="access_key" value="{{ site.formdrop_key }}">
  <input type="hidden" name="subject" value="New message from my site">
  <input type="hidden" name="redirect" value="https://example.com/thanks">
  <input type="text" name="name" required>
  <input type="email" name="email" required>
  <textarea name="message" required></textarea>
  <input type="checkbox" name="botcheck" style="display:none">
  <button>Send</button>
</form>

Add formdrop_key: ... to _config.yml, then {% include contact.html %} on any page.

Supported fields

• access_key — your key (required).
• email — if present, FormDrop sets it as Reply-To so you can answer directly.
• subject — optional email subject.
• redirect — optional thank-you page URL for plain HTML posts.
• botcheck — hidden honeypot; if a bot fills it, the submission is silently dropped.

Every other field is included in the email and saved in your dashboard log. Send Accept: application/json to get a JSON reply instead of a redirect.

Test it

1. Create a free access key with your email.
2. Paste the key, deploy, submit a test message.
3. Check your inbox and the dashboard log. If mail is delayed, the submission is still stored in the log.
