We built the spam filter we wanted for our own clients.
We look after business websites for a living, and spam was the complaint we heard most. The tools we tried either annoyed visitors with puzzles or quietly deleted real inquiries without saying why. So we built Cayve: it stops the junk, explains itself, and never throws a real customer away.

What we believe
Never lose a real message
A spam filter that deletes one customer inquiry has cost more than all the spam it stopped. When Cayve isn’t sure, it asks you.
Explain every decision
You should never have to wonder why a message went missing. Every decision comes with reasons anyone can read.
Keep as little as possible
Message text is deleted after 30 days. What helps Cayve learn is scrubbed, encrypted and yours to switch off.
Fail safe
If Cayve is slow or unreachable, your forms carry on. Protection should never be the reason a customer couldn’t reach you.
Who we are
Cayve is made by HJI Technologies, LLC, a US software company that designs, builds and runs websites and web platforms for businesses. Cayve protects the sites we look after every day, so we feel every wrong decision ourselves, and fix it.
We read every message sent to us. If you have an idea, a complaint or a question, we’d like to hear it.

See it on your own site.
