// Process up to 1 million emails per batch

{
  "event": "bulk.completed",
  "job_id": "job_123456",
  "total": 10000,

  "invalid": 1500
}

Detection Capabilities

Disposable Email Detection

Identify temporary and disposable email addresses from services like:

Mailinator
10minutemail
Guerrilla Mail
And 5000+ other disposable domains

Disposable emails are often used for spam, fake signups, or avoiding follow-up communications.

Role-based Email Detection

Detect role-based addresses that may have multiple recipients:

Type	Examples	Risk Level
General	info@, contact@	Medium
Support	support@, help@	Medium
Sales	sales@, marketing@	Low
Technical	admin@, webmaster@	High

Catch-all Domain Detection

Identify domains configured to accept all emails, where individual address verification is inconclusive.

Free Provider Detection

Flag emails from free providers like Gmail, Yahoo, or Outlook to segment your marketing strategies.
