How do I stop spam submissions coming through my website form?

Layer three cheap defenses: an invisible honeypot field that bots fill in and humans never see, a timing check that rejects submissions completed in under three seconds, and reCAPTCHA v3 or Cloudflare Turnstile running quietly in the background. That combination kills most spam without making real customers solve puzzles.

If junk still gets through, add server-side validation on the phone field, block messages containing links, and route every submission into your CRM so your team works a filtered list. Avoid checkbox captchas on mobile, since they cost you real leads to save a few junk emails.
