Stop FunnelKit Spam Without CAPTCHAs
Your opt-in form is where bots drop fake leads into your funnel by the dozen. ActiveLayer scores every opt-in on the server and blocks the fakes before the lead is ever created. Real subscribers never see a puzzle.

Everything Your FunnelKit Funnels Need to Stop Spam Leads
Server-Side AI
Every opt-in is scored by AI on our servers. There is no challenge to render and no widget loading in your visitor’s browser.
Zero CAPTCHAs
No puzzles, no checkboxes, no “select all the traffic lights.” Your opt-in stays exactly as FunnelKit renders it.
Blocks Before the Lead
A spam verdict stops the opt-in cold. No contact is written and no automation fires, so there is nothing to clean up later.
Built for FunnelKit Opt-ins
It covers the lead-capture step whether the form is embedded on the page or opens as a two-step pop-up.
A Clear Inline Error
A blocked visitor sees a plain message on the form, “Submission blocked: your entry was flagged as spam.” Nothing a bot can learn from.
On By Default
FunnelKit protection switches on the moment your API key connects. There is no separate setup step and nothing to configure first.
The Submissions Log
Every opt-in is logged, blocked or clean, and tagged Lead so you can tell funnel opt-ins apart from your contact-form traffic.
Fails Open
If our API is slow or unreachable, opt-ins proceed as if the check passed. A real subscriber is never blocked because of an outage on our end.
Respects FunnelKit First
If FunnelKit’s own validation already rejected a submission, ActiveLayer doesn’t waste an API call second-guessing it.

Why FunnelKit Sites Switch to ActiveLayer
Real subscribers get in. Bots don’t. Nobody solves a puzzle.
The Lead List You Build Stays Real
A lead list full of bots is more than clutter. It poisons your automations, skews your funnel conversion rate, and burns send volume on inboxes that were never real. ActiveLayer keeps junk contacts out of your list from the start, so every lead you nurture is someone who actually opted in. No list scrubbing, no fake welcome sequences, no second-guessing your opt-in count.

Lead Capture Is the Chokepoint. We Guard It.
Your opt-in is the one form that has to stay open to strangers, which is exactly why bots aim for it. ActiveLayer scores each submission on the server, in the same request, after FunnelKit finishes its own validation and before a lead exists. A spam verdict re-renders the form with a plain inline error and writes nothing. The bot never becomes a contact in your list, and a real subscriber never notices the check ran.

Watch It Work in the Submissions Log
A spam filter you can’t see is one you can’t trust. ActiveLayer logs every opt-in it processes, blocked or clean, in ActiveLayer → Submissions. Opt-ins are tagged Lead, with the email, the verdict, and the score behind it. If a real subscriber ever gets caught, open the entry and report it. The AI retrains on that signal, so the same mistake gets less likely over time. You audit the door instead of trusting it blindly.

An opt-in is a high-intent moment. Someone decided your offer is worth their email. Handing them a puzzle right then costs you completions, up to 40% of people abandon a form when a CAPTCHA gets in the way. ActiveLayer checks submissions through its API with hidden signal fields, so there is no challenge to solve. Real subscribers just join.

Frequently Asked Questions
Install the free ActiveLayer plugin, then paste your API key in Settings → ActiveLayer. FunnelKit opt-in protection is on by default the moment the key connects, so there is no separate step. You can confirm it under ActiveLayer → Integrations, where FunnelKit shows as Active with a toggle to turn it off.
The opt-in re-renders with a plain inline error: “Submission blocked: your entry was flagged as spam.” No lead is created and no automation fires. The message gives a bot nothing to learn from, and you can customize it in code if you want different wording.
This integration gates opt-in and lead-capture forms, which is where spam leads come in. If you sell through a FunnelKit checkout, that surface is covered by the ActiveLayer for WooCommerce integration, not this one. One ActiveLayer key turns on both, so your opt-ins and your checkout are protected from a single settings page.
The submitted email and name, plus hidden behavioral and environment signals ActiveLayer adds to the form. The plugin injects invisible signal fields into the opt-in, so the AI sees how the submission was made, not just what was typed. If a custom template drops those fields, the check still runs on the email and name alone.
It’s built to avoid that. ActiveLayer is tuned to never block a real lead first and catch bots second, and it blocks only on a clear spam verdict. Every checked opt-in lands in the Submissions log with its verdict, confidence score, and signals, so you can audit every decision made at your door. If a legitimate subscriber is ever caught, report it from the log and the AI retrains on that signal.
ActiveLayer fails open. Opt-ins proceed as if the check passed, and your funnel never breaks because we had a bad afternoon. Spam protection resumes automatically the moment the API is reachable again.
