How to find anyone's work email using the Finder API

The Finder API starts with a real name and public company domain, then resolves toward the organization's actual work identity pattern.

Hook

You do not need the final mailbox domain to start. A public-facing company domain is often enough.

How to find anyone's work email using the Finder API

The Finder accepts a full name and an organization domain. That domain can be the public website, not necessarily the final mailbox domain. Relentless Identity handles the domain discovery work behind the scenes.

What the Finder expects

Start with the best person-level information you have and the domain your users already recognize.

Code snippet

{
  "full_name": "John Smith",
  "email_domain": "company.com"
}

What you get back

Use it when you know the person but not the address.
Feed the result straight into CRM enrichment or analyst workflows.
Pair it with identity_probe when you need an additional verification step on a single address.

Why SMTP verification is dead for precision outreach

Modern enterprise mail systems are built to defeat enumeration. Precision teams need identity verification, not another mailbox guesser.
