How does your email verifier work?

Our verifier employs a sophisticated, multi-stage process designed for B2B accuracy. It first checks the email syntax and format, then validates the domain and mail server. Next, it performs a real-time mailbox ping (without sending an email) to confirm the inbox exists and can receive messages. Finally, it screens for known spam traps, disposable emails, and role-based addresses (like info@, sales@), providing a comprehensive deliverability score for each entry.

Can I verify emails in bulk?

Absolutely. Our platform is built for scale and efficiency. You can easily upload a CSV or copy-paste a list containing thousands of email addresses into our secure dashboard. Our system will process the entire list in seconds, providing you with a detailed report that categorizes each address as valid, invalid, risky, or unknown, ready for immediate action or integration.

What happens if I exceed my credit limit?

If you reach your monthly credit limit, you will be notified and can choose to upgrade your plan to access more credits immediately.
