Clean Lists.
Zero Bounces.
Better Delivery Rates.

Our verification achieves 99.5%+ accuracy on valid email detection. We use multiple verification layers including syntax checking, DNS/MX validation, SMTP verification, and spam trap databases to ensure the highest accuracy possible.

Valid emails are confirmed deliverable. Catch-all emails go to domains that accept all addresses (deliverable but unverified). Risky emails may be valid but have higher bounce probability - includes disposable addresses, role-based emails, and domains with poor sending reputation.

Most lists complete within minutes. A 10,000 email list typically verifies in 2-3 minutes. Larger lists may take longer depending on server response times and queue depth.

No. We use SMTP-level verification that checks mailbox existence without actually sending emails. This means zero impact on your sender reputation and no alerts to email owners.

No hard limit. We process millions of emails daily for enterprise customers.
