For growing teams
Your contact form stopped being a lead channel and became a mailbox to clean.
We put it back to being a lead channel: change one field, the address the form sends to, and real enquiries arrive sorted, with the right person already named on them.

Why the form matters
The risk is not the forty you delete
If enquiries are how work reaches you, the form is not an admin task. It is the top of the pipeline. And the risk is not the forty messages you delete. It is the one real enquiry sitting between them, from someone who is also asking two of your competitors this afternoon.

Humainbox sits between the form and your mailbox. You change one field, the address the form sends to, and real enquiries arrive with the right person named on them.
Humainbox
Resolves the visitor's true reply address before the message reaches you, records where it found it, and flags the messages where it cannot find one. A dead end is visible rather than silent.
The failure nobody notices
A reply sent to the wrong address looks exactly like an answered enquiry.
Most contact forms send mail from the website's own address, and put the visitor's address somewhere inside the message instead. Hit reply and you write back to your own server. The message leaves your outbox, it lands in your sent items, and as far as anyone in the team can see, that enquiry was handled.
Nobody chases it, because nothing looks wrong. The enquirer thinks you ignored them. That is the quietest way a business loses work, and it will not show up in any report.
The real cost
Spam that looks like an enquiry has to be read before it can be dismissed.
The obvious rubbish costs nothing. It is recognisable in half a second and gone. What costs is the message written in fluent English, addressed to your company by name, referencing a service you actually offer, and asking a question a real prospect might ask. Someone has to read it to the end to decide. Then the next one. Then the next.
That attention comes out of the same person whose job is to answer real enquiries quickly. Do it thirty times a day and the response time on genuine work gets worse, which is precisely the metric the form exists to protect.
01
It checked the message and judged it machine-written
A keyword filter counts links and capital letters; this reads the whole message. It found a generic outbound sales pitch with a booking link and no specific detail about your business, and scored that reading at +83 — llm_classification, the signal that actually decides.
02
It arrived through your own form
Coming in through the contact form, from the site's own domain, counts in the message's favour — form_provenance, −15. Real enquiries arrive the same way, so where it came from lowers the suspicion rather than settling it.
Spam · 68
Held at 68, just over the line
The signals sum to 68 against a balanced threshold of 60, so the message is held — never deleted, still readable, one click from your inbox. You move that line looser or stricter per inbox.
Start in dry run, where nothing changes.
You should not have to trust a new system with your pipeline on day one. In dry run every message is delivered exactly as it is now — we only record what we would have held, so at the end of the week you judge the calls on your own enquiries. Move to live if it reads your traffic the way you would; if we are ever unavailable, mail is forwarded, never held.
