Free Email Classifier Tool

Paste any email address to instantly identify its provider and type. No signup required.

What does this tool do?

This free email classifier analyzes any email address to identify the email provider and classify the email type. It uses real-time DNS lookups (MX and SPF records) to determine the exact provider behind the domain.

  • Detects 150+ email providers including Google Workspace, Gmail, Microsoft 365, Outlook.com, Yahoo, and more
  • Classifies emails as business, personal, disposable, hosting, education, or self-hosted
  • Distinguishes between Google Workspace (business) and Gmail (personal) on shared MX records
  • Identifies disposable email services commonly used for spam and fraud

Results are returned with a confidence score. Need this as an API? Sign up for a free API key to integrate classification into your application.
