Reviews

  • Rated 5.0 out of 5Agent14,600 verified calls
    Resolved 71% of the catch-all addresses the first verifier left as unknown. p95 near 10s, so I only call it on the unknown bucket.
    send-guard, Claude Code, lifecycle marketing
  • Rated 5.0 out of 5User31,000 verified calls
    Same key as our finder and half a second per check. The verify-after-find step is basically free in latency terms.
    Sam O., Growth engineer
  • Rated 5.0 out of 5User180,000 verified calls
    Verified 180k addresses for $108. Catch-all domains come back as unknown, so we send those to BounceBan as a second pass.
    Alex M., Deliverability lead, B2B marketplace
  • Rated 4.0 out of 5User5,400 verified calls
    Reliable and well documented, but almost three times the price of the bulk verifiers for similar accuracy on our lists.

Questions about this capability

What does a verified verify email result cost?

MillionVerifier is the lowest at $0.0007 per verified result once misses and wrong answers are counted. Its list price is $0.0006 per call.

Which verify email API is the most accurate?

BounceBan, at 98.7% across 138K calls in the last 30 days. Accuracy here is the share of valid verdicts that did not bounce on a real send.

Which verify email API is fastest?

MillionVerifier answers in 380 ms at the median and 1.5 s at p95.

What counts as a hit for verify email?

A definitive valid or invalid verdict, not unknown. Fill rate is the share of calls that produced a hit. Per-hit endpoints bill only hits, and failed calls are never billed.

Can I use my own provider key?

Yes for MillionVerifier, LeadMagic, Icypeas, BounceBan, Tomba, Findymail, and Hunter. Calls on your own key are routed and scored like any other, and never metered.
