How the Customer Onboarding email list is built with Tomba
This isn’t a static file that quietly rots. Every departments list is assembled live from the Tomba API and verified before it reaches you — current, deliverable, and yours to export in minutes.
- 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
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
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
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 Customer Onboarding 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 Customer Onboarding 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: "support", // support 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);
}
}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.
Transparent, pay-as-you-go pricing
