Cold sales email now arrives with perfect authentication, warmed-up mailboxes, and domains built to look like real companies. We collect it, clean it, and show you exactly how it got through.
Example record. Domains use the reserved .example ending and don't belong to anyone.
Spam filters check whether a message really came from the domain it claims. None of that tells you whether the domain itself is honest.
A domain one letter or word off from the real company, so the main domain's reputation stays clean.
Automated tools trade friendly messages for weeks to build a sending history that filters trust.
SPF, DKIM, and DMARC all pass, because they're configured correctly. The checks confirm who sent it, not whether you wanted it.
Low volume per mailbox, spread across many mailboxes, keeps every one of them under the radar.
It isn't random. Most spikes follow a public event that put your business into a list somewhere.
Filings are public records that list firms scrape the same week they're published.
New business registrations get harvested for outreach, often before your website is up.
Registration data and new-site signals get watched by tools built for exactly this.
Newswire distribution puts your contact details in more databases than you'd expect.
Scrapers find it within days and sell it on as part of a verified list.
It usually means a mailbox, a website, or your domain settings were used without your permission. Here's how to find out which, and fix it for free.
