Key takeaways
- check_circleConverted to dollars per 1,000 checks, published rates on this page run from about $0.08 to about $19.50. Same job, 240x apart.
- check_circleZeroBounce has the highest entry rate here: its published pay-as-you-go minimum is $39 for 2,000 credits, which is $19.50 per 1,000.
- check_circleKickbox holds a flat $0.010 per email from 500 credits to 2,500, then eases to $0.008 at 5,000. Predictable, and expensive at volume.
- check_circleMillionVerifier at $89 for 50,000 and EmailListVerify at $186 for 100,000 are the value picks among the dedicated verifiers, at roughly $1.78 and $1.99 per 1,000.
- check_circleReoon is the most generous free tier in the category: 600 credits a month that refill daily, with API access on the free plan.
- check_circleCredits that never expire (Bouncer, DeBounce, Reoon, EmailListVerify packs) beat monthly subscriptions when your volume is lumpy rather than steady.
- check_circleMailsfinder is ours and it is the cheapest per check on this page, roughly $0.10 per 1,000 on the $19.99 Growth plan, because the same credit pool also covers finding.
- check_circleNeverBounce is reviewed here but carries no price in the tables. Its pricing page returns a 403 to anything that is not a browser, so nothing could be verified.
Why verification pricing is so hard to compare
Every vendor prices verification differently. Some sell credit packs that never expire, some sell a monthly subscription with a credit allowance, some quote a per-email rate that only applies above a volume you have not reached, and a few run a calculator that will not show you a number until you enter a list size. Put four pricing pages side by side and the only honest conclusion is that they are not comparable as printed.
There is one unit that makes them comparable: dollars per 1,000 verified addresses. It works because a verification is one unit of the same work everywhere, a live check against the recipient's mail server. Convert every plan to that unit and the differences stop being marketing and start being arithmetic.
Two things distort the number if you are not careful. The first is the tier you quote from, because almost every vendor gets cheaper with volume, so an entry-tier rate and a 100,000-address rate can differ by five times at the same vendor. Every rate in the tables below names the tier it came from. The second is expiry: a cheap pack you cannot finish before it expires is not cheap, which is why the comparison table flags which credits expire.
One more thing worth knowing before you compare anything. Catch-all domains accept mail to every address, so no verifier can confirm a specific mailbox on one. Vendors handle those differently: some charge full price and return Unknown, some charge extra, and DeBounce charges 10 credits rather than 1. If a meaningful share of your list sits on catch-all domains, that policy moves your real cost more than the headline rate does.
The tools at a glance
How we evaluated these tools
Every price here was read from the vendor's own pricing page in September 2026, or from our research data after it was re-verified against that page on the same day. Where a vendor publishes no figure, the cell says so rather than carrying an estimate. Rates are quoted per 1,000 checks with the source tier named, because a rate without a volume attached is not a rate.
Dollars per 1,000 checks
The only unit that makes credit packs, subscriptions and per-email rates comparable.
The tier the rate came from
Nearly every vendor gets cheaper with volume, so a rate quoted without its tier is meaningless.
Whether the credits expire
A pack that expires before you finish it costs more than its sticker. Monthly allowances usually reset.
What a catch-all costs
No verifier can confirm a mailbox on a catch-all domain. What you are charged for that answer varies.
Three pricing models, and which one suits your volume
Before comparing rates, work out which shape you are buying. The cheapest rate in the wrong shape is not cheap.
Credit packs that never expire
Bouncer, DeBounce, Reoon and EmailListVerify sell credits outright. Best when your volume is lumpy: one big list this quarter, nothing the next. You pay more per unit than a subscription at the same volume, and nothing is wasted.
Monthly subscriptions with an allowance
Mailsfinder, Clearout and ZeroBounce's ONE plan give you a monthly pool. Cheapest per unit if your volume is steady and you actually use the allowance. Unused credits usually reset, so an under-used subscription quietly costs more than the sticker.
Every tool, side by side
Rank is a table position, not a promotional order.

Rates read from each vendor's pricing page in September 2026. The order is cheapest published rate first, which is a sorting choice, not a ranking. Each rate names the tier it came from in the pricing table further down. NeverBounce is reviewed but has no published figure to quote. Cost per unit uses each vendor's best published rate, which is usually a larger pack or plan than the entry price in the column beside it, so the two do not divide into each other.
Cost calculator
What your list actually costs to verify
Figures use each vendor's published rate at a mid-volume tier, named in the pricing table above, rather than the entry-tier rate. DeBounce uses its published floor of $0.00045 and will be higher at small volumes. NeverBounce is left out because it publishes no figure.
| Tool | Addresses you can check | Rate used |

Rates read from vendor pricing pages in September 2026. Real cost moves with your catch-all share and with the tier you qualify for at checkout.
The tools, reviewed
Every tool gets the same card: what it is, four features, three pros, three cons, and an honest read. Same format for ours as for everyone else's.
Mailsfinder
Subscription, finder in the same pool
Ours, so check the numbers against the pricing page and read the cons first. Verification runs a live SMTP check and reports catch-all domains as their own status rather than quietly calling them valid. One credit buys a verification and three buy a found address, out of the same pool, which is why the per-check rate lands below the dedicated verifiers: the pool is priced for two jobs. Starter is $9.99 for 75,000 credits a month, Growth $19.99 for 200,000, Agency $49 for 600,000.
Key features
- checkLive SMTP check, not a lookup the result reflects what the mail server says now, not a stored record.
- checkCatch-all reported separately flagged as its own status rather than folded into valid.
- checkOne pool for verify and find 1 credit to verify, 3 to find, charged only when an address comes back.
- checkDaily verification caps 3,000 a day on Starter, 8,000 on Growth, 20,000 on Agency.
Pros
- addLowest published rate per 1,000 on this page
- addFinding and verifying share one balance
- addFree tier renews daily, no card
Cons
- removeNo API below the Growth plan
- removeMonthly credits do not roll over
- removeNewer platform with a thin review record
The honest read
Strong on unit price and honest about catch-alls. What you give up is the API on the two cheapest tiers and the long public review record the incumbents have.
DeBounce
Pay as you go, lowest quoted floor
DeBounce publishes no tier table. It runs a slider: pick a volume between 5,000 and 5,000,000 and it quotes you. The floor it advertises is $0.00045 a check, which would be the cheapest dedicated verifier here, though you need serious volume to reach it and the page will not show the intermediate steps without entering a number. Credits never expire and there are no monthly payments. The detail to watch is the credit schedule: a catch-all check costs 10 credits and enrichment costs 20.
Key features
- checkVolume slider from 5K to 5M no tier table, you enter a volume and it quotes.
- checkCredits never expire no monthly commitment and no setup cost.
- checkFree deduplication duplicates removed before they consume credits.
- checkCatch-all costs 10 credits the single most important line in their pricing for a dirty list.
Pros
- addLowest advertised floor rate here
- addCredits never expire
- addDeduplication included at no charge
Cons
- removeNo published tier table to compare
- removeCatch-all checks cost 10 credits each
- removeNot in our verified review data
The honest read
Potentially the cheapest dedicated verifier on this page, and the hardest to price without entering your volume. The 10-credit catch-all charge deserves a look before you commit a messy list.
Reoon
Best free tier in the category
With 1,018 G2 reviews at 4.8, Reoon has the strongest verified rating on this page, and its free tier is the reason people find it: 600 credits a month that refill daily, with live API access included, which almost no competitor offers below a paid plan. Paid credits are one-time purchases that never expire, $11.90 for 10,000 and $29.66 for 25,000, putting it around $1.19 per 1,000. There is also a recurring AppSumo lifetime deal from $79 for teams that want daily credits without a subscription.
Key features
- check600 free credits a month refilled daily on login, with no card required.
- checkAPI on the free tier rare at any price and genuinely useful for scripting.
- checkCredits never expire one-time purchases rather than a subscription.
- check1,018 G2 reviews at 4.8 the highest verified rating in this comparison.
Pros
- addMost generous free tier on this page
- addAPI access without paying
- addHighest verified G2 rating here
Cons
- removeVerification only, no finder
- removeAround $1.19 per 1,000, above the bundled tools
- removeSmaller company, lighter enterprise tooling
The honest read
The one to start with if you are testing, because the free tier is large enough to be a real trial rather than a demo. At volume it is mid-priced rather than cheap.
MillionVerifier
Value pick among dedicated verifiers
Bulk lists are the whole product here, and the pricing reflects it: $39 for 10,000 credits, $59 for 25,000 and $89 for 50,000, which is roughly $1.78 per 1,000 at the middle tier. There is also a separate automated plan priced by daily throughput rather than credits, from $15 a month for up to 10,000 a day, which is unusually good value if you genuinely verify every day. G2 coverage is thin at 28 reviews, though the rating is a solid 4.3 and the tool has a long reputation among cold email operators.
Key features
- checkCredit packs from $39 10,000 credits, with rates falling to about $1.78 per 1,000 at 50,000.
- checkDaily-throughput plans from $15 a month for up to 10,000 addresses a day.
- checkBuilt for bulk large list handling is the core use case rather than an add-on.
- check4.3 on G2 across 28 reviews small sample, consistent score.
Pros
- addGood rate without needing huge volume
- addDaily plans suit steady verification
- addLong track record on bulk lists
Cons
- removeOnly 28 G2 reviews to judge by
- removeVerification only, no finder
- removeInterface is dated next to newer rivals
The honest read
The safe mid-market choice: not the cheapest, not the most polished, and unlikely to surprise you. The daily-throughput plan is the underrated option if your volume is regular.
EmailListVerify
Cheapest published rate at real volume
The published tier table goes further than almost anyone else's, from 1,000 credits at $5 all the way to 10,000,000, and the rate keeps falling: $186 for 100,000 works out near $1.86 per 1,000, and $659 for 1,000,000 reaches roughly $0.66. That last figure is the cheapest large-volume rate on this page with an actual number attached to it. There is a parallel monthly subscription from $16 for 5,000 a month if you prefer a recurring allowance to a pack.
Key features
- checkTiers published up to 10 million one of the few vendors that shows the whole ladder.
- checkRoughly $0.70 per 1,000 at a million the lowest published large-volume rate here.
- checkPublished ladder, 1,000 to 10,000,000 $5 for 1,000 falling to $0.36 per 1,000 at ten million.
- check100 free credits on signup enough to sanity-check the results.
Pros
- addCheapest published rate at high volume
- addFull tier ladder published openly
- addBoth pack and subscription models
Cons
- removeNot in our verified review data
- removeEntry rate of $5 per 1,000 is unremarkable
- removeNeeds real volume to reach the good rates
The honest read
The right answer if you verify hundreds of thousands of addresses and want a number you can check rather than a quote. At small volumes there is nothing special here.
Bouncer
Credits never expire, no charge for unknowns
The pricing ladder is clean and fully published: $8 for 1,000, $60 for 10,000, $400 for 100,000, down to $2,000 for a million, which is $0.002 an email at the top. Two policies do more work than the rate. Credits never expire, and you are not charged for duplicates or for addresses that come back unknown, which on a messy list is a real discount rather than a marketing line. The European base and GDPR posture make it a common shortlist entry for EU teams.
Key features
- checkNo charge for unknown results you pay for answers, not attempts, which is unusual.
- checkNo charge for duplicates deduplication happens before billing.
- checkCredits never expire packs bought outright, no subscription needed.
- checkAuto-refill available for teams that want pack pricing with subscription convenience.
Pros
- addNot billed for unknowns or duplicates
- addFull pricing ladder published
- addCredits never expire
Cons
- removeAround $4.00 per 1,000 at 100,000
- removeNot in our verified review data
- remove1,000 credit minimum purchase
The honest read
The fairest billing policy in this comparison, attached to a mid-to-high rate. On a dirty list the unknowns-are-free policy can close much of the gap to a cheaper vendor.
Hunter
Verification sold beside a finder
Verification at Hunter is a separate product from search, bought through the Data Platform: $11 for 1,000, $110 for 10,000, $690 for 150,000 and $2,800 for a million. That works out around $4.60 per 1,000 at the 150,000 tier, well above the dedicated verifiers, which is the trade you make for having finding, verifying and campaigns behind one familiar account. With 634 G2 reviews at 4.4 it has the documentation and support depth the cheaper tools do not.
Key features
- checkVerification credits sold separately from search credits, on the Data Platform.
- checkFinder, verifier and campaigns one account, one vendor, one invoice.
- checkBest documentation in the category client libraries in most languages.
- check634 G2 reviews at 4.4 the deepest review base among the finders here.
Pros
- addOne vendor for finding and verifying
- addStrong documentation and support
- addLarge verified review base
Cons
- removeAround $4.60 per 1,000, above dedicated verifiers
- removeVerification credits billed separately from search
- removeIndependent tests put the verifier below its claim
The honest read
You are paying for the ecosystem rather than the verification. Sensible if you already run Hunter, poor value if verification is all you need.
Emailable
Developer-facing, scored results
Both models are offered side by side and the monthly one is consistently cheaper: 5,000 credits cost $38 pay-as-you-go or $32.30 a month, and 50,000 cost $245 against $208.25. At the 5,000 tier that is roughly $7.60 per 1,000 on pay-as-you-go. The product leans developer-facing, with the API reference published next to the pricing and a numeric score returned alongside the state, which is more nuance than a simple valid or invalid verdict.
Key features
- checkBoth PAYG and monthly published the monthly rate runs about 15 percent below PAYG.
- checkNumeric score with each result beyond a binary valid or invalid verdict.
- checkAPI reference beside the pricing an unusually developer-first presentation.
- check250 free credits on signup enough for a real sample.
Pros
- addClear side-by-side PAYG and monthly rates
- addScore adds nuance to each result
- addDeveloper documentation is strong
Cons
- removeAround $7.60 per 1,000 at the 5,000 tier
- removeNot in our verified review data
- removeVerification only, no finder
The honest read
A well-built product at an unremarkable price. The score is genuinely useful if you want to set your own risk threshold rather than accept a vendor's.
Clearout
Subscription with a steep annual discount
Monthly pricing is unremarkable, at $19.50 for 3,000 credits and $40 for 10,000, but the annual discount is among the steepest in the category: the same Starter plan drops to $16 a month and the Pro 25K tier falls from $146 to $60, which takes the effective rate from roughly $5.84 per 1,000 down near $2.40. The free plan is 100 credits for the lifetime of the account rather than a monthly refill, so it is a sample rather than a usable tier.
Key features
- checkSteep annual discount Pro 25K falls from $146 to $60 a month on annual billing.
- checkMonthly credit allowances 3,000, 10,000 and 25,000 tiers published.
- check100 lifetime free credits a one-time sample, not a recurring allowance.
- checkCRM and ESP integrations limited on the free tier, full on paid.
Pros
- addAnnual billing more than halves the rate
- addClear published tier table
- addSolid integration coverage
Cons
- removeMonthly rate around $5.84 per 1,000
- removeFree credits are one-time, not recurring
- removeNot in our verified review data
The honest read
Judge it on the annual price, not the monthly one. Committing for a year takes it from expensive to competitive, which is a real choice rather than a trick.
Kickbox
Flat rate, most predictable
Pricing here is the simplest in the comparison and also among the highest: a flat $0.010 an email from 500 credits through 2,500, easing to $0.008 at 5,000. No subscription, no commitment, no tier maths. What you are buying alongside the verification is the Sendex deliverability score on every lookup and a reputation for conservative, accurate verdicts, which matters more to teams protecting an established sending domain than to anyone optimising unit cost.
Key features
- checkFlat $0.010 an email to 2,500 no tier table to model, no commitment.
- checkSendex score on every result a deliverability signal beyond valid or invalid.
- check100 free verifications no monthly or annual commitment required.
- checkConservative verdicts a reputation for accuracy over optimistic results.
Pros
- addSimplest pricing to budget against
- addDeliverability score on every lookup
- addNo commitment of any kind
Cons
- remove$8.00 to $10.00 per 1,000, the second highest here
- removeNo meaningful volume discount published
- removeVerification only, no finder
The honest read
You pay a clear premium for simplicity and caution. Defensible when a domain's reputation is worth more than the verification bill, hard to justify otherwise.
ZeroBounce
Deliverability suite, highest entry rate
With 1,361 G2 reviews at 4.7, this is the most reviewed tool in the comparison, and the price reflects the position: the published pay-as-you-go minimum is $39 for 2,000 credits, which is $19.50 per 1,000 and the highest entry rate on this page. The ONE subscription starts at $99 a month for a minimum 10,000 credits, roughly $9.90 per 1,000, with unused credits rolling over. What the money buys beyond verification is inbox placement tests, blacklist monitoring, DMARC monitoring and warmup seeds.
Key features
- checkFull deliverability suite inbox placement, blacklist and DMARC monitoring included.
- checkCredits roll over on ONE one of the few subscriptions that does not reset them.
- check1,361 G2 reviews at 4.7 the deepest verified review base here.
- check100 free credits a month recurring rather than one-time.
Pros
- addMost reviewed tool in this comparison
- addDeliverability tooling well beyond verification
- addSubscription credits roll over
Cons
- remove$19.50 per 1,000 at the published PAYG minimum
- removeFinder costs 20 credits per search, billed separately
- removeSuite is dead weight if you only need verification
The honest read
Buy it for the deliverability suite or do not buy it. Judged purely on cost per check it is the most expensive option here by a wide margin.
NeverBounce
No publicly readable pricing
Included for completeness rather than comparison. Every attempt to read the NeverBounce pricing page in September 2026 returned an HTTP 403 to non-browser clients, so no figure on this page could be verified and none is quoted. The product itself is long-established and ZoomInfo-owned, with a real-time API and bulk list cleaning, and it appears on most shortlists in this category. If you are evaluating it, open the pricing page in a browser and compare the quote against the verified rates in the table above.
Key features
- checkReal-time and bulk verification the standard feature set for this category.
- checkZoomInfo-owned part of a larger data platform rather than a standalone tool.
- checkPricing behind a calculator no public table a client can read.
- checkEstablished product long history and wide recognition in the category.
Pros
- addLong-established product
- addReal-time API and bulk cleaning
- addPart of a larger data platform
Cons
- removePricing page unreadable to non-browser clients
- removeNo figure could be verified for this comparison
- removeNot in our verified review data
The honest read
We will not quote a price we could not read. Check it yourself in a browser and hold the quote against the verified numbers above before deciding.
Which one fits your situation
Match the pricing model to how your volume actually arrives.
| If this is you | Start here |
|---|---|
| You verify a big list once or twice a year | Buy a pack that never expires. Bouncer at $400 for 100,000 and EmailListVerify at $186 for 100,000 both sit here, and neither puts a clock on the credits. |
| You verify steadily every month | A subscription wins on unit cost. Mailsfinder at $19.99 for 200,000 credits a month is roughly $0.10 per 1,000, the lowest published rate on this page. |
| You need the cheapest possible rate and volume is large | EmailListVerify reaches roughly $0.70 per 1,000 at its 1,000,000 credit pack, and DeBounce quotes a floor of $0.45. Both need real volume to get there. |
| You are testing before you commit | Reoon gives 600 credits a month that refill daily, with API access on the free plan. Mailsfinder gives 100 a day but no API below the Growth plan. |
| Your list is heavy on catch-all domains | Read the catch-all policy before the rate. DeBounce charges 10 credits for a catch-all check, which changes your effective cost more than any headline discount. |
| You also need to find addresses, not just check them | Mailsfinder and Hunter draw both from one balance. With a dedicated verifier you are buying a second tool for the finding half. |
Five ways verification budgets go wrong
Every one of these comes from comparing a rate to a rate instead of a total to a total.
Comparing entry rates instead of your-volume rates
Almost every vendor gets cheaper with scale. Bouncer is $0.008 per email at 1,000 credits and $0.002 at a million, a 4x swing at one vendor. Price your actual list size, not the number on the pricing button.
Ignoring what a catch-all costs
Nobody can confirm a mailbox on a catch-all domain, but you still pay for the answer. DeBounce charges 10 credits for that check rather than 1. On a list where a fifth of domains are catch-all, that detail outweighs a 20 percent discount elsewhere.
Buying a subscription you will not use
A monthly allowance is the cheapest unit rate only if you consume it. Credits that reset unused turn a $0.10 rate into whatever you actually paid divided by what you actually checked, which is usually a much worse number.
Treating an expiring pack as a cheap pack
Packs from Bouncer, Reoon, DeBounce and EmailListVerify do not expire. Some competitors' do. A discount you cannot finish spending is not a discount.
Paying twice because finding and verifying are separate products
Hunter sells verification credits separately from search credits. Most dedicated verifiers do not find addresses at all. If you need both, count both bills before you compare anything.
Category picks
Lowest published rate
Mailsfinder works out around $0.10 per 1,000 checks on the $19.99 Growth plan, with finding drawn from the same credits.
Best value dedicated verifier
MillionVerifier is roughly $1.78 per 1,000 at its $89 pack for 50,000, with a long track record on bulk lists.
Most generous free tier
Reoon gives 600 credits a month that refill daily, and puts API access on the free plan, which almost nobody does.
Cheapest at real volume
EmailListVerify reaches roughly $0.70 per 1,000 on its 1,000,000 credit pack, the lowest large-volume rate with a published number.
Credits that never expire
Bouncer sells packs outright from $8 for 1,000, does not charge for duplicates or unknown results, and never expires them.
Most predictable pricing
Kickbox holds a flat $0.010 per email across its small tiers, which makes budgeting trivial even though the rate is high.
What you actually pay
The same tools with the tier each rate comes from. Two vendors are deliberately incomplete: DeBounce publishes a floor rate rather than a table, and NeverBounce publishes nothing a non-browser client can read.
| Tool | Free plan | Entry price | Tier the rate comes from | Cost per 1,000, best plan |
|---|---|---|---|---|
| Mailsfinder | 100 credits a day, no API | $9.99/mo Starter | 75,000 credits a month | ~$0.1 |
| DeBounce | 100 credits, no card | Volume-quoted | 5K to 5M credit bands | ~$0.45 |
| Reoon | 600 credits a month, API included | $11.90 one-time | 10,000 credits, never expire | ~$1.19 |
| MillionVerifier | Trial credits on signup | $39 one-time | 10,000 credits | ~$1.78 |
| EmailListVerify | 100 credits on signup | $5 one-time | 1,000 credits | ~$1.86 |
| Bouncer | 100 credits, no card | $8 one-time | 1,000 credits minimum | ~$4.00 |
| Hunter | 50 credits a month | $11 one-time | 1,000 verification credits | ~$4.60 |
| Emailable | 250 credits on signup | $38 pay as you go | 5,000 credits | ~$4.90 |
| Clearout | 100 credits for life | $19.50/mo Starter | 3,000 credits a month | ~$6.50 |
| Kickbox | 100 verifications free | $5 one-time | 500 verifications | ~$8.00 |
| ZeroBounce | 100 credits a month | $39 pay as you go | 2,000 credits | ~$19.50 |
| NeverBounce | Not verifiable | Not published | Not published | n/a |
