¹ Hunter figures verified 7 Aug 2026 against hunter.io/pricing (prices geo-served in GBP to our UK server; Hunter states 0.5 credit = 1 email verified - per-1,000 figures derive from those two page-shown facts). Annual billing is cheaper. ² Accuracy figures are vendor claims, not independent benchmarks.
Hunter.io is primarily an email finder that includes verification as part of a subscription plan. If you already have your email list and only need to verify it, you're paying for email finding features you don't use. BounceZero is exclusively an email verification service - the entire product is optimised for accuracy, speed, and signal depth.
Hunter now sells unified credit subscriptions (verified Aug 2026): Starter is £41/month for 2,000 credits and a verification costs 0.5 credit - about £10 per 1,000 verifications, falling to roughly £6.25 on the Growth tier. Those credits also cover finder searches, which is the point of Hunter's bundle. BounceZero is a flat $3 per 1,000 verifications, no subscription, credits never expire - cheaper whenever verification is all you need.
Hunter's verifier returns SMTP status, MX record check, disposable flag, and a confidence score. BounceZero runs a 5-stage pipeline: DNS, SMTP deep handshake, 65+ Bayesian signals, ML scoring, and plain-English explanation. For cold email or marketing lists where deliverability matters, BounceZero provides actionable intelligence on every address.
Many teams use Hunter.io for email discovery and BounceZero for verification - the best of both. The workflow is straightforward:
Verification-only cost at equivalent volumes
Hunter figures derived from hunter.io/pricing as verified 7 Aug 2026 (monthly billing, 0.5 credit per verification, GBP as geo-served to the UK); Hunter credits also cover finder searches. BounceZero figures: bouncezero.io/pricing.
For verification-only use, usually yes. BounceZero charges $3 per 1,000 verifications with no subscription. Hunter bundles verification into subscription credit plans (verified August 2026: Starter £41/mo for 2,000 credits, with 1 verification costing 0.5 credit - roughly £10 per 1,000 verifications on that tier, less on higher tiers). If you also need email finding, the Hunter bundle can make sense - see our finder-vs-verifier guide.
BounceZero is a dedicated email verification service, not an email finder. Hunter.io combines email finding with basic verification. If you already have email addresses and need to verify them, BounceZero provides deeper verification - 65+ signals vs Hunter's 15 - at a fraction of the cost.
Yes. BounceZero is a UK-registered company (ICO registration ZC132839) with EU/UK data residency and a signed DPA available. Hunter.io is French-based and GDPR-compliant. BounceZero provides deeper verification signals per email for the same compliance investment.
BounceZero reports 99.8% accuracy using a 5-stage pipeline with Bayesian scoring, ML models, SMTP deep probing, and plain-English explanations. Hunter.io's verifier reports 95%+ accuracy using primarily SMTP and MX checks without machine learning scoring.
BounceZero is built exclusively for verification - deeper signals, lower cost, no bundled features you don't need.
