Frequently Asked Questions

B2B Email Verifier FAQ

How does your email verifier work?

Our verifier uses a multi-step process to ensure maximum accuracy. It first checks the email syntax for format correctness. Then, it verifies the domain and mail server (MX records) to confirm they are active and accepting mail. Finally, it performs a safe, non-intrusive ping to the mailbox itself (without sending an email) to confirm its existence. This combination of checks delivers over 99% accuracy in identifying valid, invalid, and risky addresses.

Can I verify emails in bulk?

Absolutely. B2B Email Verifier is built for scale. You can easily upload a CSV or Excel file containing thousands or even hundreds of thousands of email addresses.

What happens if I exceed my credit limit?

Credits are consumed for each email address you verify. If you exceed your monthly plan's credit limit, you will have the option to purchase a top-up pack of additional credits to continue service uninterrupted, or your account will resume verification capabilities at the start of your next billing cycle.
