Zambo launch: Verified research, zero fluff**\n\nHi [Name],\n\nNo more cold-guessing leads. Zambo is live.\n\nThis isn’t another AI wrapper that hallucinates contact info. It’s a precision research engine for contractors and local service businesses. You provide the trade and city; Zambo returns five qualified, source-backed leads in under 60 seconds.\n\nWe just ran a live test for web designers in Austin, TX. The system returned zero results. That’s the point.\n\nMost tools invent names to look helpful. Zambo doesn’t. If there’s no verifiable data, it tells you there’s none. That’s why we include a unique receipt link for every run. It proves exactly what was returned—and what wasn’t. A receipt confirms the saved bytes, not the quality of the lead, but it guarantees transparency. You know precisely what you’re working with before you dial.\n\nWe support 24 trades across any US city. You get three free searches per day per IP. No auth. No credit card. Just immediate, verifiable data.\n\nThe launch email below is ready for your review. It highlights the \"no-results\" feature as a trust signal, not a bug.\n\n**Draft Launch Email:**\n\n> **Subject: Why we didn’t find you any leads (yet)**\n>\n> Hi [Prospect Name],\n>\n> Most AI lead tools will happily invent a name and email address just to keep you happy.

We’d rather show you an empty list than a fake one.\n>\n> Want to see it in action? Here’s a live receipt from our Austin, TX web design scan: [Link]\n>\n> Notice the \"no_results\" status? That’s integrity.\n>\n> Ready to run your own?
