How it works

The Actor leverages Tomba's powerful Email Verifier API to perform comprehensive email validation:

Process Flow

1. Authentication: Connects to Tomba API using your credentials
2. Input Processing: Accepts array of email addresses to verify
3. Email Verification: Uses Tomba's emailVerifier method for each email
4. Validation Checks: Performs regex, SMTP, MX record, and deliverability tests
5. Rate Limiting: Automatically handles 150 requests/minute limit
6. Data Storage: Saves detailed verification results to Apify dataset

What You Get

For each verified email, you'll receive:

• Verification Result: Valid, invalid, risky, or unknown status
• Confidence Score: 0-100 score indicating verification confidence
• Technical Checks: Regex validation, MX records, SMTP server status
• Risk Factors: Disposable email detection, webmail identification
• Deliverability: Accept-all domain detection, block status
• Quality Metrics: Gibberish detection and comprehensive analysis
