Formkit.xyz

Form handling for plain HTML.

Post your form. Get the response by email.

Formkit gives a regular HTML form somewhere to submit. No frontend framework, no dashboard, no JavaScript required.

Point your form at https://formkit.xyz/?email=you@example.com, submit it, and Formkit sends the contents to your inbox in the same clean format used by the emails it generates.

Built for simple sites that just need a form backend.

Use it with plain HTML

This is the whole idea. Add an action, keep your normal fields, and optionally set a few metadata values with hidden inputs. 

<form action="https://formkit.xyz/?email=you@example.com" method="POST">
  <input type="hidden" name="_subject" value="New website message" />
  <input type="hidden" name="_replyto" value="hello@example.com" />

  <label>
    Name
    <input type="text" name="name" />
  </label>

  <label>
    Email
    <input type="email" name="email" />
  </label>

  <label>
    Message
    <textarea name="message"></textarea>
  </label>

  <button type="submit">Send</button>
</form>

Useful fields
