Email verification services compared
Email verification is sold two ways: a monthly subscription against a credit allowance, from about $16 to $99 a month, or pay-as-you-go credit packs from about $3 per 1,000 on a small pack to under $1 at a million. SimpleVerifier charges $29.99 a month and does not meter verifications at all. Below is every vendor’s cheapest route, read off their own pricing page — including the two that beat us, and when.

Vendor by vendor
Each page says what that tool charges, where its pricing model bites, and who should keep paying for it instead of switching.
Kickbox
$3.00–$10.00/1kWhere it bites: verification is billed per email, so cleaning a large list is a variable cost you cannot forecast from the plan price.
Compare with SimpleVerifierBouncer
$2.00–$8.00/1kWhere it bites: credit-based pricing means the second pass over a list costs the same as the first.
Compare with SimpleVerifierDeBounce
$0.44–$3.00/1kWhere it bites: there is no flat option, so every pass over the list is billed again — the cost scales with how often you clean, not just how much.
Compare with SimpleVerifierEmailListVerify
$16/mo or $1.86–$5.00/1kWhere it bites: the allowance is the ceiling — a list past 5,000 pushes you up the tiers fast, and a 100,000-address clean is a $186 pay-as-you-go job.
Compare with SimpleVerifierHunter.io
$49/moWhere it bites: credits are allocated per year rather than per month, so a heavy quarter draws down the annual allowance early.
Compare with SimpleVerifierClearout
$49/moWhere it bites: the monthly cap resets whether you used it or not, so an uneven workload pays for capacity it never touched.
Compare with SimpleVerifierNeverBounce
$50/moWhere it bites: credits expire, so an allowance bought for a campaign that slipped a quarter is simply gone.
Compare with SimpleVerifierZeroBounce
$99/mo or $3.00–$19.50/1kWhere it bites: credits are the unit, so the bill scales with list size and a re-verification of the same list costs full price again.
Compare with SimpleVerifierHead to head, without us in the answer
Comparisons between two competitors, where the verdict is whichever of them actually suits you. We appear once at the bottom of each, labelled as our own pitch.
ZeroBounce vs NeverBounce
NeverBounce is roughly half ZeroBounce's price for verification alone, so if verification is all you need it is the better value.
Hunter.io vs ZeroBounce
These are different products.
DeBounce vs EmailListVerify
On published pay-as-you-go rates DeBounce is cheaper at every size both sell: 10,000 addresses cost $25 at DeBounce and $27 at EmailListVerify, and 100,000 cost $135 against $186.
Kickbox vs Bouncer
Both sell pay-as-you-go credit packs at similar prices (5,000 addresses cost $40 at Kickbox and $35 at Bouncer as of October 2026), and both are credible verifiers, so price is not the deciding factor.
When we are not the right choice
Two vendors in the table above are cheaper than us in specific, common cases. We would rather say so here than have you find out after paying.
- One small list, cleaned once — use DeBounce
- A single 10,000-address clean costs $25 there against our $29.99, and the credits never expire. If your list is that size and you are not going to verify again, a subscription is the wrong instrument and we are the wrong vendor. Above about 10,000 addresses the arithmetic flips.
- Under 10,000 a month, steady — use EmailListVerify
- Their subscriptions are $16 a month for 5,000 credits and $25 for 10,000. At 5,000 that is $168 a year less than us, and if that volume genuinely covers you, the extra we offer is capacity you will never touch.
- You need outreach sending too — use Hunter
- Campaigns, sequences, connected mailboxes and a writing assistant are a different product from a verifier. We replace one part of Hunter, not all of it, and running both to save on verification is usually a false economy.
Where we do win is narrower and easier to state: large lists, because volume does not change the price, and lists verified repeatedly, because a confirmed result is cached for 14 days and the second pass costs nothing. At 100,000 addresses cleaned quarterly, every per-address model in this table costs more than $29.99 a month.
How to test a verifier before you pay for it
Price is the easy part to compare and the least important. Accuracy is what you are buying, and it takes about two minutes to test on any vendor:
- Invent an address at a real domain — something like
qx7zzt-not-real@gmail.com. Verify it. A tool doing real mailbox checks returns invalid. A tool checking only syntax and MX returns valid, because the domain is fine. - Check a catch-all domain. Many corporate domains accept every address. An honest result is “accepts all addresses” or risky — not valid, because nothing was confirmed.
- Re-run the same list. If the second pass costs the same as the first, you are paying twice for one answer.
- Read what the statuses mean. A verifier that has no risky category is hiding its uncertainty inside “valid”, which is where bounces come from.
Our rule, for what it is worth: 8,740 disposable domains are blocked outright, and anything the probe could not confirm comes back risky rather than valid. You can run the test above on our free single-address checker without an account.
Common questions
- What is the best email verification service?
- It depends on how often you clean and how big the list is, and the honest answer is not always us. For a one-off clean of up to about 10,000 addresses, DeBounce is cheaper: $15 for 5,000 or $25 for 10,000, with credits that never expire. For a steady list of up to 10,000 a month, EmailListVerify's subscriptions ($16 for 5,000, $25 for 10,000) undercut us. SimpleVerifier at $29.99 flat wins on larger lists and on lists you re-verify often, because neither of those adds to the bill. If you also need outreach sending, Hunter is a platform rather than a verifier and replaces more of your stack.
- What is the cheapest email verification service?
- For one pass over a small list, DeBounce is the cheapest of the vendors here: $15 for 5,000 addresses or $25 for 10,000, with no subscription and credits that do not expire. For a recurring small volume, EmailListVerify at $16 a month for 5,000 credits is cheapest. For large or repeatedly verified lists, a flat plan wins — SimpleVerifier is $29.99 a month regardless of volume, so the per-1,000 cost falls towards zero as usage rises.
- Do all email verifiers do real SMTP mailbox checks?
- No, and this is the difference that matters more than price. Some tools only check syntax and MX records, then return valid for anything on a live domain. A real check opens an SMTP conversation with the recipient's mail server and asks whether the specific mailbox exists. Test any vendor by verifying an address you invented at a real domain — if it comes back valid, the mailbox was never checked.
- How much should email verification cost per 1,000 emails?
- Published pay-as-you-go rates in this market run from about $3 to $10 per 1,000 on the smallest packs down to under $1 per 1,000 on million-address packs from the cheapest vendors, so the rate you actually pay depends heavily on list size. On a flat plan the per-1,000 figure is not fixed at all — it falls as you verify more, which is why the right comparison is total annual cost for your actual volume rather than any single per-1,000 rate.
- Is a subscription or pay-as-you-go better for email verification?
- Pay-as-you-go is better if you clean a list once and rarely repeat it, because you buy exactly what you use and good providers do not expire the credits. A subscription is better if you verify continuously or in unpredictable bursts, because the second and third pass over a list cost nothing extra. The mistake is buying a subscription for a one-off job, or paying per address for work you repeat monthly.
