Our global verification infrastructure is distributed across multiple regions to ensure consistent speed and reliability regardless of where the target mailbox is hosted. The API responds in Real-time, and our bulk processing engine handles up to 50,000 emails per hour. We support 25+ native integrations with popular marketing platforms and CRMs, plus a well-documented REST API for custom implementations. Our verification results include detailed status codes, risk scores, and actionable flags so you can make informed decisions about every address on your list.

Great initiative! The user interface looks very clean and beginner-friendly. I really like how it simplifies the workflow. Are you planning to add a dark mode or any third-party integrations in the future?

Congratulations on the launch! I really appreciate the minimalist design and how straightforward your onboarding process is. It's quite refreshing to see a tool that solves a specific problem perfectly without overwhelming the user with too many complex features right from the start. I’m just curious to know, what was the biggest technical challenge you faced while building the core features for this product?

Email verification accuracy varies wildly with catch-all domains — how does BillionVerify score those? In recruiting outreach, catch-alls are a huge share of corporate addresses, so a clear confidence score there matters more than raw bounce-rate claims.
