Spam protection that never loses a real customer.
Cayve reads every message your website receives, explains each decision in plain English, and holds anything it isn't sure about for you to review. Nothing is deleted. Your visitors never see a CAPTCHA.
Free monthly allowance on every account. No card needed to start.
Three answers, and a reason for each
Real messages go straight through
A customer asking for a quote reaches your inbox the moment they press send. No puzzle, no delay.
Unsure? It waits for you
Anything borderline is kept in a held inbox with the reasons spelled out. Release it with one click and the original notification is sent as if nothing happened.
Obvious spam is stopped, not thrown away
Blocked messages are kept for 30 days. If Cayve ever gets one wrong, you can still get it back, and telling Cayve so teaches it for next time.
Why site owners choose it
Plain-English reasons
"Sent 0.9 seconds after the form opened, faster than a person can fill it in." You see why, every time, and so does your team.
Fast enough to be invisible
Most checks answer in under 100 milliseconds. If Cayve is ever unreachable, your forms keep working and the message is checked afterwards.
Your rules, per site
Decide what happens to sales pitches, SEO outreach or job seekers on each site. Hold them, block them, or let them through.
Learns from you, not just about you
Mark a message as spam or real and that site changes at once. Wider patterns only change after review, so one bad label can't hurt everyone.
Built for WordPress first
Comments, reviews, registrations and twelve form plugins out of the box. One plugin, one key, and a held inbox inside wp-admin.
Minimal data, by design
Message text is removed after 30 days. Addresses and senders are kept only as keyed hashes. Your customers' words aren't a product.
