Spam Filter
for AI.
Centralised form submission spam filtering with AI-powered content analysis, email reputation checks, and business context matching.
// what it is
Every contact form on a client website is a target for spam bots and low-quality lead submissions. This server runs a four-layer scoring pipeline (content analysis, email reputation, business context matching, and Workers AI for borderline cases) before a submission ever reaches the CRM. Your AI assistant can check submissions, audit email addresses, review filtering stats, and feed back on false positives.
GOOD FOR // Web agencies managing contact forms across multiple client sites who want AI-assisted spam filtering that improves over time without tuning each site separately.
// what you can do
Form submission screening
Pass any inbound form submission through the full scoring pipeline. Gets a spam verdict with a confidence score before it is forwarded or saved anywhere.
Standalone email reputation checks
Check an email address against reputation signals without processing a full submission. Useful for validating a contact before adding them to a CRM or list.
Feedback and continuous improvement
Mark a decision as spam or legitimate to improve future scoring. Feedback is idempotent so running it twice on the same submission is safe.
Filtering statistics
Pull per-domain filtering stats for any time period: see how many submissions were blocked, how many passed, and where the borderline cases landed.
