Outbound is mostly written about by people selling volume. We write about the other half: what to refuse, why, and what the numbers say once you start counting refusals.
Six months of running Knockwire against our own business, with every refusal counted and filed under the gate it failed. The ratio is real. About a third of it turns out to be data cleaning rather than judgment.

Business to business contact through a published form is permitted across most of the world. Two European jurisdictions are strict enough that we switch them off by default and make the user turn them back on.
Fifteen points off the fit threshold, four weeks, one client. Messages delivered rose from 81 to 214. Replies went the other way, from 11 to 9.
Buyer, timing, Door, permission. In one quarter these four gates turned down 12,022 companies out of 12,410, and some of them were companies we wanted.
The word scraping appears on the site of our best customer, our nearest competitor and an agency that has never written a line of code. So we read something else.
The contact form is the last inbound channel nobody has automated to death. That is the entire advantage, it is borrowed rather than owned, and the only way to keep it is to send less than you could.
A Door is a usable public contact route. Finding one on an arbitrary website is platform archaeology, a scoring function, and two guards that have to fail closed.
A global opt-out is one sentence in a policy and a week of engineering. Domain keys, a check at every stage, a compare-and-set at delivery, and rows nobody deletes.
A CAPTCHA, a 429 and a robots directive are the same sentence in three dialects. When we meet one, the job stops and waits for a person. That is the design, not a fallback.
Job posts go stale, changelogs lie by omission, funding data lands a quarter late, and stack detection reports one page view. Here is how we weight anyway.
One specific true sentence beats four paragraphs of personalisation tokens, and the reason is mechanical rather than aesthetic.
We pointed Knockwire at Crawlbase and read the rejections in order. Our stated target customer turned out to be wrong in two separate places.
Two bad answers dominate this question. One says GDPR banned cold outreach in 2018, the other says business contact is exempt. The real position sits between them and is legible if you read the instruments in order.
Anyone can send fifty thousand messages this afternoon for the price of a lunch. Capacity stopped being scarce years ago. Judgement did not.
