B2B data engineering & RevOps telemetry

MX-Verified & Catch-All Segregated Account Intelligence

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.

What each account is checked for

Three layers of evidence per account, all read from public DNS records and the company's own website.

I

DNS & DMARC Governance Audit

Whether the domain can receive mail at all, and how strictly it protects its own name.

  • MX record lookup; domains with no mail server are removed
  • DMARC policy read as reject, quarantine, none or missing
  • Catch-all mail gateways flagged
II

Paid-Ad Funnel & Tech-Stack Telemetry

What the company is running on its website right now, read from the page itself.

  • Google Tag Manager and Meta Pixel detection
  • HubSpot, Salesforce, Stripe and Calendly signals
  • A factual opening line per account, based on what was found
III

3-Tab Executive Excel Dossier

One workbook, ready for a CRM import or a leadership review.

  • Executive Briefing: counts and shares for every check
  • Tier A Prime: the accounts with the strongest signals
  • Full Dataset: every account, every column, every status

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.
