Frequently Asked Questions
How accurate is your email validation?
We use comprehensive checks - syntax validation, MX record verification, and live SMTP connection testing - so results are highly reliable for most common providers and business domains. No service can verify every address with 100% certainty, though: some servers (catch-all domains, greylisting, and providers like Outlook/Microsoft or Yahoo) intentionally hide whether a mailbox exists, and we honestly report those as "Unknown" rather than guessing.
Is your service free to use?
Yes, our email validation service is completely free. You can validate single emails and bulk lists up to 1000 emails per request without any cost.
Do you offer API access?
Yes, we provide a comprehensive REST API for integrating email validation into your applications. Check our API documentation for details.
