Company enrichment without a data vendor: domains to emails, tech stack and MX

What a lead list actually needs

You have a list of company domains. You want, per company:

• contact emails and phone numbers,
• social profiles,
• the technology stack they run,
• the ATS they use for hiring,
• and their email infrastructure (MX provider, SPF, DMARC).

The hard requirement is not volume. It is provenance — knowing which page each value came from, so you can defend a contact when someone asks "where did you get this?"

Every value carries its source

The Domain Contact Enricher returns one row per domain. Contacts are ranked by confidence, and each carries the URL where it was found:

{
  "domain": "example.com",
  "companyName": "Example Inc.",
  "emailCount": 2,
  "emails": [
    { "email": "hello@example.com", "confidence": "high", "isRoleAccount": true, "sourceUrl": "https://example.com/contact" }
  ],
  "socialProfiles": { "linkedin": "https://www.linkedin.com/company/example", "github": "https://github.com/example" },
  "technologyIds": ["nextjs", "cloudflare", "hubspot"],
  "atsProvider": "greenhouse",
  "atsJobScraperInput": "greenhouse:example",
  "emailInfrastructure": {
    "mailProvider": "Google Workspace",
    "hasSpf": true,
    "hasDmarc": true
  }
}

The atsJobScraperInput field chains directly into the ATS Job Scraper — domain in, hiring board out.

An honest coverage note

Modern companies increasingly hide behind contact forms. This actor returns contacts when the site publishes them on its home, contact, about, team or imprint pages — it does not invent addresses or scrape private data. If it finds none, you get a profile row with the technology and email infrastructure, not a fabricated email. That is the correct behaviour for a list you intend to email.

Usage

{
  "domains": ["stripe.com", "shopify.com", "tesla.com"],
  "maxPagesPerDomain": 4,
  "includeTechnologies": true,
  "includeDnsSignals": true
}

It also respects robots.txt by default and reports unreachable domains as unbilled error rows.
