How Our Name-Based Email Finder Works

1. MX & Provider Discovery

We verify that the company domain has active Mail Exchange (MX) records and identify whether it uses Google Workspace, Microsoft 365, Zoho, or custom mail gateways.

2. Pattern Permutation

We normalize diacritics and generate the 6 corporate naming conventions that cover 98% of B2B organizations (first.last@, first@, flast@, f.last@, first_last@, last.first@).

3. Live SMTP & Catch-All Probe

Unlike static email permutators, we test candidates against the company's mail server in real time and flag catch-all domains so you never burn your sender reputation.

Frequently Asked Questions

How does the free email finder work?

Enter a contact's first name, last name, and company domain. Our engine verifies the domain's MX servers, generates the top 6 corporate patterns, and tests them via SMTP to find the best match.

Does the person receive an email when I search for them?

No. Our SMTP handshake closes before the DATA command, so no message is ever sent.
