Everything Your Contact Form Needs to Beat Spam
Forget reCAPTCHA widgets, honeypot fields, and manual moderation. One API call handles all of it.
Content Analysis
ActiveLayer's AI examines message content for spam patterns, link stuffing, and gibberish text. Catches sophisticated spam that honeypots miss completely.
Email Validation
Every sender email is checked against disposable domain lists, reputation databases, and formatting rules. Fake emails are flagged before they reach your inbox.
IP Reputation Scoring
Each submission is evaluated against known spam networks, proxy lists, and geographic risk signals. Repeat offenders are caught on the first attempt.
Confidence Scores
Every verdict includes a confidence score from 0 to 1 and human-readable detection signals. You decide your own threshold for blocking vs. reviewing.
Auto-Approve and Auto-Reject
Set your spam threshold once. Submissions above it are rejected automatically. Submissions below it pass through instantly. No manual review required.
Zero Client-Side Scripts
Nothing loads in your visitors' browsers. No cookies, no tracking pixels, no JavaScript widgets. Your form stays fast and your visitors stay private.
Automatic Fallbacks
If the ActiveLayer API is ever unreachable, submissions pass through by default. Your contact form never breaks. Your users never see an error.
One Call. Any Language.
Send the submission, read the verdict, decide what happens next.
