How the Incident Response email list is built with Tomba

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

  1. 01

    Target

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

  2. 02

    Discover

    Domain Search pulls the current decision-makers and their work emails from each matching company, live rather than from a recycled dump.

  3. 03

    Verify

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

  4. 04

    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 build this list with Tomba

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 can reach leads they cannot validate.

Verified before you send

Syntax, MX and SMTP checks plus catch-all detection keep bounces low, and every confirmed hard bounce earns a credit back.

Sources you can check

Every address comes from public web pages Tomba crawls, and the sources behind any email are one request away.

Pay only for results

If Tomba can’t find an email, the search is free: only searches that return a result use a credit.

API, SDKs & MCP

A REST API with 13 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 Incident Response 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.

// npm install tomba
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 Incident Response list
const { data } = await reveal.companiesSearch({
  query: "companies with 50+ employees",
  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",
    department: "management", // management contacts
  });

  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);
  }
}

With the MCP server connected, ask your AI assistant:

“Use Tomba to find companies with 50+ employees, pull their management contacts with domain_search, verify every email including catch-all domains, add direct-dial numbers with phone_finder, then export the Incident Response email list.”

Works in Claude, Cursor, Windsurf and any MCP client. The companies_search, domain_search, email_verifier and phone_finder tools run live. See the remote MCP docs.

Every address comes back with its verification status, catch-all domains included. See the Reveal, Domain Search and Verifier docs for full options.

// pricing

$8.98/ 1,000 search credits

On Pro Plus (50,000 a month). An Email Finder search that returns an address uses 1 credit; Domain Search uses 1 per 10 results.

Includedverification status

Every address a search returns comes with its verification status, catch-all domains flagged, on the same search credit.

$0for empty searches

If Tomba finds no valid address, the search is free. The same search again in the same usage window is free too.

Start free: 25 search credits every 30 days, no card required.

Plans from 2,500 to 350,000 search credits a month, or one-time packs valid for 12 months. The REST API, 13 SDKs and the MCP server come with every plan.
