Honeypot Detection
An invisible field that catches automated bots filling every input. Humans never see it, bots always fill it.
Behaviour Checks
Blocks submissions that arrive faster than a human can type, or with no typing or clicking on the form at all.
Keyword Blocking
Define your own list of blocked words. Any message containing them is stopped before it reaches your inbox.
AI Spam Filter (Pro)
Catches SEO pitches, commission offers and other sales messages your keyword list misses. Blocked messages wait on a review page, so a real customer caught by mistake still gets a reply.
