Email Verifier - Bulk Email Validation

Verify email addresses at scale using a 4-layer verification pipeline: format validation, DNS/MX lookup, SMTP handshake and disposable domain detection. Clean your lists before sending.

Verification Pipeline

Format check - RFC 5322 compliance
Disposable detection - 300+ known throwaway providers (mailinator, yopmail, guerrillamail, etc.)
MX record lookup - confirms domain can receive email
SMTP verification - connects to mail server, checks if mailbox exists
Catch-all detection - identifies domains that accept all addresses

Result Statuses

valid - address exists and accepts mail
invalid - doesn't exist, bad format, no MX, or disposable
catch_all - domain accepts everything (can't verify individual mailbox)
risky - MX exists but SMTP check inconclusive (server blocked port 25)

Input Example

{
  "emails": [
    "john.doe@company.com",
    "test@mailinator.com",
    "invalid-email",
    "contact@startup.io"
  ],
  "smtpCheck": true,
  "smtpTimeout": 5000
}

Output Example

{
  "email": "john.doe@company.com",
  "valid": true,
  "status": "valid",
  "subStatus": "deliverable",
  "formatValid": true,
  "mxValid": true,
  "smtpValid": true,
  "isDisposable": false,
  "isCatchAll": false,
  "mxRecords": [{"exchange": "mail.company.com", "priority": 10}],
  "durationMs": 823
}
