How does your email verifier work?

B2B Email Verifier employs a sophisticated, multi-layered verification process. First, it checks the email syntax for format correctness. Then, it validates the domain name and retrieves its mail server (MX) records. Following this, the tool performs a real-time SMTP handshake (without sending an actual email) to ping the mailbox and confirm its existence. Finally, it uses proprietary algorithms to detect disposable emails, catch-all domains, and role-based addresses, categorizing each entry as "Deliverable," "Risky," or "Invalid."

Can I verify emails in bulk?

Yes, bulk verification is a core functionality. You can upload a list of thousands of email addresses via a CSV or TXT file directly to the platform's dashboard. The system processes the entire list rapidly, providing you with a downloadable report that segments the emails by their verification status. This allows for efficient cleaning of large contact lists gathered from lead generation activities, event registrations, or purchased databases.

What happens if I exceed my credit limit?

Credits are consumed each time an email address is verified. If you exceed your monthly credit limit based on your chosen plan, you will need to purchase additional credit packs or upgrade to a higher-tier plan to continue using the service. The system will typically notify you as you approach your limit, allowing you to manage your usage proactively and avoid interruption in your verification workflows.
