Send us an account list. Every company domain is checked at the DNS level, its DMARC policy, ad tracking and tech stack are read from public records and its own website, and the result comes back as a three-tab Excel dossier your team can act on.
Mail servers are checked per domain and catch-all gateways are kept apart. Checking individual mailboxes is available through an optional verifier API integration.
Three layers of evidence per account, all read from public DNS records and the company's own website.
Whether the domain can receive mail at all, and how strictly it protects its own name.
What the company is running on its website right now, read from the page itself.
One workbook, ready for a CRM import or a leadership review.

Every figure in a dossier comes from a live lookup at the time of the run. DNS records, websites and mailboxes change, so each dossier is dated.
