Why Use an Email Validation API?

What We Check

Email Format Validation - Ensures proper syntax (name@domain.com)
Domain Verification - Confirms the domain exists
MX Record Check - Verifies mail servers are configured
Disposable Email Detection - Blocks temporary email services
Free Provider Detection - Identifies Gmail, Yahoo, Outlook, etc.

Email Validation API Features
