One bot-filled HighLevel form fires the whole workflow: junk contacts tagged, SMS credits burned, pipelines polluted, client reports wrong. SpamKill decides after capture — invisible to real leads, 99.9% accuracy, and your workflows, tags, and UTMs stay exactly as built.
Works with HighLevel forms and surveys, plus WordPress, Keap, HubSpot, ActiveCampaign, and custom stacks.

Only the rare flagged visitor ever sees a verification step — everyone else sees nothing, and a real person who is flagged verifies in one step and comes through. Depending on your plan, you can also review what was blocked.
Bots don't stumble onto your forms — they hunt for them. Automated crawlers look specifically for forms wired to CRMs and marketing automation, because those are the submissions that get an autoresponder, an SMS, a retargeting tag: proof the pipe is live. Funnels and landing pages built on popular platforms share recognisable markup, which makes them easy to find at scale, and once one crawler catalogues a form, the URL circulates.
In most tools a junk submission is a row to delete. In HighLevel it's a live event. The contact is created and tagged, the workflow fires, the SMS and email sends go out, the pipeline stage fills, and the month-end report quietly absorbs it all. By the time anyone notices, the credits are spent and the automation has already introduced your client to a bot.
Now multiply by every client sub-account you manage. The same junk gets cleaned ten times over, the sales teams you report to waste calls on leads that were never people, and the client sees the inflated numbers before you do. That compounding cost is specific to running automation at agency scale — we've broken down the mechanics in what bot leads actually do inside a CRM.
Three ways agencies handle it — and what each one costs.
HighLevel can add a CAPTCHA to forms and surveys, and it will stop some bots. But you're adding a visible step to funnels that were engineered to convert — and on paid traffic, every visitor who hits that puzzle was a click you already paid for. Solver services pass CAPTCHAs for pennies, and whatever the gate turns away leaves no record: a real prospect who gave up looks exactly like a bot that was blocked, which is to say they look like nothing at all.
Tagging workflows, suppression lists, and manual contact review can catch junk once it's in. The trouble is everything that already happened on the way in — the automation fired, the credits burned, the client's report skewed — and the cleanup repeats per sub-account, forever. Filtering after the workflow runs is paying the cost and then also paying to hide it.
SpamKill sits on the form itself and scores how each submission was filled in — timing, movement, input cadence, device signals — at 99.9% accuracy. Real visitors see nothing and hit send. The rare flagged visitor verifies in one step and continues — a false flag doesn't cost the lead — while bots fail the check and never fire an automation. Depending on your plan, you can also review the blocked list and flag false positives. Your workflows, tags, and UTMs stay exactly as built.
Swap it in during the 30-day trial — no credit card, blocked-lead review included — and let the blocked queue show you what it catches on real traffic. Don't run a CAPTCHA and SpamKill together on the same form: your visitors get the friction of both, and the gate keeps turning real people away before anything can capture and verify them. The swap is safe because a flagged real person can always verify straight through. Not sure invisible detection can carry the load alone?

Every month, SpamKill emails you the numbers per client domain — total submissions, blocked, passed, and the cleanup time that never had to happen. Forward it as-is, or fold it into your own reporting.

Bots don't find forms by accident — they crawl for forms wired to CRMs and automations, because those are the submissions that get a response. Funnels and landing pages built on popular platforms are easy to recognise at scale, so they get hit constantly. Each junk submission costs the spammer nothing and costs you a contact record, a fired workflow, and SMS or email credits.
HighLevel can put a CAPTCHA on forms and surveys. It stops some bots, but it adds a visible step to funnels that were engineered to convert, solver services pass CAPTCHAs cheaply, and whatever it turns away leaves no record — you can't review a lead that was never captured.
SpamKill decides after capture instead of gating before it. It scores how the form was filled in — timing, movement, input cadence — at 99.9% accuracy. Real visitors see nothing; the rare flagged visitor verifies in one step and comes straight through, so a false flag doesn't cost the lead. Depending on your plan, you can also review everything that was blocked and flag false positives — and your workflows, tags, and UTMs stay exactly as built.
Yes — that's the recommended rollout. Pilot on one to three client domains where the spam is worst, set a strictness level per client, and compare blocked versus passed per domain in the monthly report before rolling it out further.
Pick 1–3 client domains, swap SpamKill in for whatever is on the form today, and watch what it catches — flagged real leads verify themselves through, and the trial includes blocked-lead review. Thirty days, no card.
