Domain Search: How to Find All Email Addresses at a Company

What Is Domain Search?

Domain search is a technique used to discover all email addresses associated with a specific company domain (e.g., company.com). Instead of searching for one person at a time, domain search reveals the email format, known contacts, and organizational structure of a company.

This is particularly valuable for account-based sales and marketing, where you need to identify and engage multiple stakeholders at a target company.

How Domain Search Works

Domain search tools aggregate data from multiple sources:

1. **Web crawling**: Scanning publicly available pages that mention email addresses from the domain 2. **Pattern analysis**: Identifying the email format used by the company (e.g., first.last@domain.com) 3. **Database lookup**: Cross-referencing against professional contact databases 4. **Public records**: SEC filings, press releases, and government records 5. **API integrations**: Combining data from professional networks and data providers
