Competitor
Infrastructure Spy.
Enter any company's domain and see exactly how they run email — mailbox provider, sending platforms, DMARC maturity, domain age — plus their entire SaaS stack, reverse-engineered from public DNS verification tokens. See how the pros are configured before you copy them. All public data, read in your browser.
TARGET DOMAINALL PUBLIC DNS + RDAP — READ IN YOUR BROWSER
HOW THIS WORKS — AND WHAT IT CAN'T DONO HACKING, JUST DNS
🛰It reads only public records. MX tells you the mailbox provider; SPF reveals their sending platforms; DNS verification tokens (TXT) expose every SaaS tool they've connected; RDAP gives age and registrar. All published by the domain owner, all readable by anyone.
🔒It cannot list their inboxes. Enumerating real mailboxes needs SMTP probing that browsers can't do and mail servers block — and it'd be user-enumeration, which we don't build. Address format is inferable; actual people are not.
🎯Why it's useful: see how mature senders configure DMARC before you copy them, know whether a prospect runs Google or Microsoft (it changes how you send to them), and read a company's whole tech stack for sales/competitive research.
Recon on your own domains too: run yours through the domain age & health checker for the warmup-readiness verdict, and spin up matching secondary domains with the domain generator.
