How this works

U.S. small-business domains from Google Places — vetted listings with real websites, not random domain lists. About 1,000 are added per month on the free monthly quota; when that runs out, discovery pauses until it resets.

Hi — I'm Alexey — I run STL Tech Handyman in St. Louis and keep this panel public so owners can see impersonation risk for free. It uses the same SPF, DKIM, and DMARC checks I run with clients.

How this works

I sample real small businesses from Google's public business directory (the same data behind Google Maps). I check each company's domain the same way you can on this site — and track how exposed it is to email impersonation as results come in.

I don't publish individual domain names — but every number here is from a real company domain.

I don't sell your email or share it with advertisers. Privacy Policy

I add about 1,000 U.S. small-business domains per month to this live panel — roughly 230/week, ~35/day, and 1–2 per hour on average. That steady pace keeps the insights free for everyone.

I'm a one-person shop running this on Google's free monthly quota — enough to keep the panel real and free, but not unlimited. When that quota is full, processing pauses until it resets.

These numbers come from real businesses — wire fraud and chargebacks hurt actual owners. I'm showing what's already out there, not selling fear.
