Live data, powered by AI

How the Cowboy email list is built with Tomba

This isn’t a static file that quietly rots. Every technologies list is assembled live from the Tomba API and verified before it reaches you — current, deliverable, and yours to export in minutes.

  1. 1

    Target

    Pick your filters — industry, technology, job title, department, company size, country or US state. Tomba Reveal maps the exact companies that match.

  2. 2

    Discover

    Domain Search pulls the current decision-makers and their work emails from each matching company in real time — pulled live, never a recycled dump.

  3. 3

    Verify

    Every address is SMTP-checked and AI-scored the moment it is found — including catch-all (accept-all) domains most tools skip — for 99% deliverability.

  4. 4

    Export

    Download fresh, verified contacts to CSV or your CRM, or pull them straight from the REST API. Built the moment you ask, so nothing is stale.

Why Tomba is the best way to build this list

AI-powered discovery

Machine-learning models rank and match the right people at the right companies, then predict the most likely deliverable pattern.

Catch-all verification

Tomba verifies catch-all / accept-all domains that other providers mark “unknown” — so you reach leads nobody else can validate.

99% accuracy

Real-time SMTP + AI checks keep bounce rates low and protect your sender reputation and domain health.

Live & fresh

Assembled on demand from live sources — never a resold, months-old database that has already decayed.

Only pay for valid emails

If Tomba can’t find a valid email, the search is free. You never spend credits on dead or guessed addresses.

API, SDKs & MCP

A REST API with 10 official SDKs, spreadsheet add-ons, and an MCP server to build this list straight into your AI tools and workflows.

For developers and AI assistants

Build the Cowboy list with the Tomba API

Reveal the companies, Domain Search their live contacts, Verify every email (catch-all included), and Phone Finder for direct dials. Copy-paste in Go, JavaScript, cURL, or MCP.

import { TombaClient, Reveal, Domain, Verifier, Phone } from "tomba";

const client = new TombaClient();
client.setKey("ta_xxxx").setSecret("ts_xxxx");

const reveal = new Reveal(client);
const domain = new Domain(client);
const verifier = new Verifier(client);
const phone = new Phone(client);

// 1. Reveal — find companies for the Cowboy list
const { data } = await reveal.companiesSearch({
  query: "companies using Cowboy",
  page: 1,
});

for (const company of data.companies) {
  // 2. Domain Search — pull live contacts + emails
  const res = await domain.domainSearch({
    domain: company.website_url,
    limit: "20",
  });

  for (const contact of res.data.emails) {
    // 3. Verifier — AI + catch-all verification (accept-all included)
    const check = await verifier.emailVerifier(contact.email);
    if (check.data.email.status !== "valid") continue;

    // 4. Phone Finder — add a direct-dial number (5 credits)
    const dial = await phone.finder({ email: contact.email });
    console.log(contact.email, contact.position, dial.data?.intl_format);
  }
}
$ npm install tomba

Verification is bundled free — Tomba scores catch-all / accept-all domains other tools skip. See the Reveal, Domain Search and Verifier docs for full options.
