Email Verification FAQ
- How accurate is SMTP Ghost's email verification?
-
Our email verification achieves 99.9% accuracy through multi-step validation. We check syntax, domain validity, MX records, and mailbox existence without sending any emails. Our system also detects catch-all domains, role-based emails, and disposable addresses.
Unlike basic validators, we use advanced SMTP handshake techniques and maintain relationships with major ISPs to ensure the most accurate results possible. This accuracy is crucial when combined with our email warming service.
- Can I verify emails in bulk?
-
Yes! SMTP Ghost handles bulk email verification from 100 to 10 million+ emails. Simply upload your CSV or connect via API for real-time verification. Our system processes thousands of emails per minute while maintaining accuracy.
Bulk verification integrates seamlessly with our lead generation tools and automation workflows, allowing you to verify leads automatically as they're collected.
- What's the difference between catch-all and valid emails?
-
A catch-all domain accepts emails to any address (even non-existent ones), making verification tricky. Valid emails are confirmed to exist at the mailbox level. SMTP Ghost identifies both types and provides risk scores.
For catch-all domains, we recommend using our inbox rotation and starting with lower volumes. Monitor engagement in analytics to identify truly active addresses.
- How often should I verify my email lists?
-
Email lists decay at 22.5% annually, so we recommend:
- • New leads: Verify immediately after collection
- • Active lists: Re-verify every 3 months
- • Cold lists: Always verify before reactivation
- • High-value campaigns: Verify 24 hours before sending
Set up automated verification workflows to maintain list hygiene without manual effort.
- Does email verification affect deliverability?
-
Absolutely! Email verification is the foundation of good deliverability. By removing invalid addresses before sending, you:
- • Maintain low bounce rates (<2%)
- • Protect sender reputation
- • Avoid spam traps and honeypots
- • Increase inbox placement rates
Combine verification with email warming and A/B testing for maximum deliverability.
- Can I integrate email verification with my workflow?
-
Yes! SMTP Ghost offers multiple integration options:
- • Real-time API: Verify emails as they're collected
- • Bulk upload: CSV files up to 10M+ emails
- • CRM integration: Connect with popular platforms
- • Lead gen tools: Auto-verify from our scrapers
Our team collaboration features ensure everyone works with clean, verified lists.
