Verdict

MillionVerifier is built for scale: a huge 10,000-verification free tier and the throughput to clean a million emails in about six hours. It's spartan beyond bulk verification and email-only, but for cheap, fast, very large cleanups it's a standout.

How BounceBlock compares

Email-only. Built for raw bulk volume, not a bundled email + phone + company workflow. BounceBlock verifies email and phone — and checks company data — in one upload, at a flat monthly price, and never bills you for an “unknown” result.
