📖 Documentation & API

🔧 How It Works

Validation Process:

  • Regex Validation: Checks email format and syntax
  • MX Records: Verifies domain has mail servers
  • SMTP Validation: Tests actual mailbox existence
  • ✅ SMTP Validation Details:

  • No emails are sent - Only SMTP handshake verification
  • Uses Amazon SES for authentication but validates against target domain servers
  • Production-grade validation with proper error handling and retry logic
  • Will NOT count against SES sending limits since no emails are actually sent
  • 🔌 API Access

    Endpoint:

    GET https://truemail.computerdx.com/api/?email=ADDRESS

    Authentication:

    Authorization: truemail-prod-token

    Example cURL Request:

    curl -H "Authorization: truemail-prod-token" \ "https://truemail.computerdx.com/api/?email=test@example.com"

    Response Format:

    { "success": true/false, "email": "test@example.com", "validation_type": "smtp", "errors": {}, "smtp_debug": [...], "mail_servers": [...], "date": "2025-01-01 12:00:00 +0000" }

    💡 Usage Instructions

    Web Interface:

  • Enter any email address in the form above
  • Select validation methods (all recommended for comprehensive checking)
  • Click "Validate Email" to see detailed results
  • Review step-by-step validation breakdown
  • API Integration:

  • Use GET requests with email as query parameter
  • Include authorization header with provided token
  • Parse JSON response for validation results
  • Check 'success' field for overall pass/fail status
  • 💰 Cost-Effective: SMTP validation uses authentication but doesn't send emails, so it won't consume your SES sending quota or incur sending charges.
