BillionVerify

BillionVerify is a comprehensive email verification and finding platform designed for sales, marketing, and outreach teams seeking to optimize their email lists. Built from the ground up, it offers a powerful step before verification—allowing users to upload CSV files of any size without limits, then receive cleaned lists via email once processed. The platform emphasizes pay-per-answer pricing, ensuring users only pay for definitive, verified results, while unknown outcomes remain free. Its new Email Finder feature can turn a name and domain into a verified work email, whether in single, bulk, or company-specific batches, charging only on successful matches. Additionally, BillionVerify provides real-time API access and a native MCP server, with 20 free credits daily, making it suitable for integrations and ongoing campaigns. Its flexible approach, combined with free rechecks within 24 hours, makes it a standout choice for teams that need reliable email validation and discovery at scale.
