Email Verification Process

Our email verification service maintains industry-leading accuracy rates:

  • 99.5% accuracy: For syntax and format validation
  • 98.7% accuracy: For deliverability verification
  • 97.9% accuracy: For comprehensive verification including role accounts and spam traps

We use multiple validation techniques including SMTP verification, domain checks, and proprietary algorithms to ensure maximum accuracy.

Each email address is categorized with detailed results:

Valid: Email is deliverable and safe to send to
Invalid: Email address doesn't exist or has syntax errors
Risky: Catch-all domains, role accounts, or disposable emails
Unknown: Verification couldn't be completed due to server issues

Additional data includes: spam trap detection, role account identification, and deliverability confidence scores.

Verification speed depends on list size and server response times:

  • Small lists (up to 1,000): 1-5 minutes
  • Medium lists (1,000-10,000): 5-30 minutes
  • Large lists (10,000-100,000): 30 minutes - 2 hours
  • Enterprise lists (100,000+): 2-24 hours

You'll receive email notifications when verification is complete, and can track progress in your dashboard.
