<form action="https://unicorn-forms.com/api/forms/submit">
  <input type="hidden" name="$to" value="YOUR_FORM_KEY">
  <input type="hidden" name="$subject" value="New inquiry">
  <input type="email" name="email" placeholder="Email">
  <input type="text" name="subject" placeholder="Subject">
  <input type="text" name="message" placeholder="Message">
  <button>Send</button>
</form>

Add as many fields as you want—email, subject, message, or anything else. Collect them all. Use $to, $subject, $success on the fly—no backend config. Change it in the HTML and ship.
