Email Verifier

A professional-grade Apify Actor that verifies email addresses with comprehensive validation.

How it works

Professional-grade email validation with multiple checks:

• ✅ Format Validation - RFC-compliant email format checking
• ✅ DNS/MX Record Verification - Checks if domain exists and has mail servers (enabled by default)
• ✅ Disposable Email Detection - Identifies temporary/disposable email addresses
• ✅ Provider Detection - Identifies email providers (Gmail, Yahoo, Outlook, etc.)
• ✅ Role-based Detection - Identifies generic addresses (admin@, info@, etc.)
• ⚙️ Mailbox Validation (Optional) - Connects to mail server to verify mailbox exists

Input

{
  "emails": ["user@example.com", "test@gmail.com"],
  "checkDomain": true,
  "validateSMTP": true
}

Parameters:

• emails (required) - Array of email addresses to validate
• checkDomain (optional, default: true) - Enable DNS/MX record checking
• validateSMTP (optional, default: true) - Enable Mailbox Validation

Output

All results include these fields:

{
  "email": "user@example.com",
  "quality": "good",
  "result": "ok",
  "resultcode": 1,
  "hasMx": true,
  "mailboxResult": null,
  "free": false,
  "role": false,
  "provider": null,
  "error": null
}

Field Descriptions:

• email - Email address (normalized to lowercase)
• quality - "good" (valid) or "bad" (invalid)
• result - "ok", "domain_not_found", "disposable", "invalid_format", "no_mx_records"
• resultcode - 1 (valid)
• hasMx - true if domain has MX records
• mailboxResult - SMTP status: "found", "not_found", "blocked", "skipped", or null
• free - true if from free provider (Gmail, Yahoo, etc.)
• role - true if role-based address (admin@, info@, etc.)
• provider - Detected provider name or null
• error - Error message or null

Example Scenarios:

Valid email:

{ "quality": "good", "result": "ok", "resultcode": 1, "hasMx": true, "error": null }

Invalid domain:

{ "quality": "bad", "result": "domain_not_found", "resultcode": 6, "hasMx": false, "error": "Domain does not exist" }

Disposable email:

{ "quality": "bad", "result": "disposable", "resultcode": 6, "error": "Disposable email address detected" }

With Mailbox Validation:

{ "mailboxResult": "found" }  // Mailbox verified
{ "mailboxResult": "blocked" }  // Server blocked verification
