Every plan includes bounce detection, spam-trap identification, catch-all verification, disposable email filtering and role-account detection. Teams use it to clean cold-email lists, B2B leads, Google Maps exports and local-business lists, and to block fake registrations — customers report that integrating the real-time API into signups reduced fake sign-ups and improved trial-to-paid conversion. It also offers native MCP Server integration so AI agents can verify emails without billing setup.
BillionVerify is aimed at sales teams, marketing teams and agencies, and even lets partners launch their own verifier. Pricing is pay-as-you-go from $0.001 per email, starting at $20 for 20,000 credits and scaling to 1,000,000 credits, with a free tier of 600 credits monthly plus 20 free credits each day you log in.
