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?
