About This Tool
Every company follows a pattern for employee email addresses. Knowing this pattern lets you predict email addresses for any person at the company, even before you have their verified email. This free tool shows you the most common email format patterns based on a company domain, so you can draft outreach emails with higher confidence.

How does the email format finder work?
+
The tool analyzes a company domain and shows the most commonly used email formats for that organization. Common patterns include first.last@domain.com, firstinitiallast@domain.com, and first@domain.com. This gives you a starting point for guessing email addresses, though we recommend verifying any email before sending.
How accurate are the email format predictions?
+
Email format patterns are predictions based on common conventions, not verified addresses. Most companies use one of 5-6 standard patterns. For verified, deliverable email addresses, use Cleanlist's email verification and enrichment tools which check against real data sources.
Can I use this to find a specific person's email?
+
This tool shows the format pattern a company uses, not individual emails. Once you know the pattern (e.g., first.last@company.com), you can construct a likely address. For verified individual emails, Cleanlist's People Search provides confirmed, triple-verified email addresses.
