How does your email verifier work?

Our verifier uses a multi-layered process for maximum accuracy. It first checks the email syntax for format correctness, then validates the domain and mail server (MX records). Finally, it performs a mailbox ping (without sending an email) to confirm the inbox actively exists and can receive messages. This entire process, enhanced by B2B-specific algorithms, happens in real-time to deliver a clear status: valid, invalid, risky, or unknown.

Can I verify emails in bulk?

Absolutely. Our bulk verification feature is built for scale. Simply upload your list in a supported format (like CSV), and our system will process thousands of emails simultaneously. You'll receive a detailed report within seconds, categorizing each address and often providing additional data points, allowing you to download a cleaned, campaign-ready list instantly.

What happens if I exceed my credit limit?

If you use all the verification credits in your monthly plan, you can purchase a top-up to continue verifying emails immediately. Alternatively, your plan will reset on its next billing cycle. We recommend monitoring your usage in the dashboard and upgrading to a higher plan if you consistently need more credits to maintain your outreach velocity and data hygiene.

Can I receive support if I need it?

Yes, dedicated support is available. You can access our comprehensive help center and documentation for instant answers. For direct assistance, you can chat with our friendly team or book a meeting for more in-depth guidance.
