How does BounceZero compare to other email verification services?

BounceZero is priced at a flat, published $3 per 1,000 verifications with no monthly subscription. It uses a 5-stage pipeline with 65+ signals including Bayesian scoring, ML models, SMTP deep probing, and Advanced catch-all classification. It offers EU/UK data residency, credits that never expire, and a free tier of 100 credits every month.

Which email verification service is cheapest?

It depends on volume and model. Among rates we verified on 7 August 2026: MillionVerifier $1.78/1K at 50K and DeBounce from $0.45/1K at top volume are cheaper per check than BounceZero at $3/1K; Bouncer is $8/1K at entry falling to $2/1K at 1M; Emailable is $7.60/1K at its 5K tier. ZeroBounce and Clearout price via on-page calculators, and NeverBounce and Kickbox block automated verification. BounceZero has no subscription, a flat rate, and credits that never expire - cheapest is not the same as best value per check.

Does BounceZero have EU data residency?

Yes. BounceZero is a UK-registered company (ICO ZC132839, Company No. 17153835) with EU/UK data residency, a signed DPA, and full GDPR compliance. Email data is processed and stored in EU/UK infrastructure only.

Verifiers we retired dedicated pages for, briefly

EmailListVerify - at six-figure volumes it costs less per check than almost anyone (their site advertised $1.86/1K at 100K, reviewed 2 Aug 2026), and their credits never expire either. If a flat Valid/Invalid/Risky verdict is all your workflow needs, it is a credible budget pick; the trade is depth - no per-signal evidence on the risky middle of your list.

Verifalia - sells verification in quality levels (Express / Standard / Premium), so price and depth move together; its API returns granular status codes. EU company, GDPR-covered like us. Free tier is per-day (25/day when last reviewed) rather than per-month.

Truemail (open source) - a capable self-hosted Ruby gem: you trade a vendor bill for server cost, Ruby dependency upkeep, and owning deliverability and compliance yourself. For small volumes self-hosting can genuinely be comparable in cost; at scale the ops time dominates.

Mailfloss - a different model, not a worse one: it auto-cleans inside your ESP (Mailchimp, Klaviyo, ActiveCampaign) on a subscription, and per-email it can be cheaper than us. You cannot point it at a CRM export or a purchased list, and idle months still bill - that is the trade.
