The best email verifiers in 2026, compared on price per 1,000 and catch-all handling

If you're building a local business list, you don't need a separate verifier: Leadraft checks every email against the live mail server as it finds it, keeps catch-alls apart as Accept-all, and never exports Invalid. If you're cleaning a list you already have, standalone verifiers cost about $1.20 to $13 per 1,000 at 10,000 emails as of November 2026. Reoon ($1.19 per 1,000 at 10,000) and MillionVerifier ($1.49 per 1,000 at 100,000) list the lowest prices we found, ZeroBounce the highest, with the most described catch-all handling, and NeverBounce, Bouncer, Emailable and Kickbox sit at $4 to $7 per 1,000. Hunter is a finder first, with verification inside its plans.

Disclosure: Leadraft wrote this. Leadraft isn't a standalone verifier: it checks the emails it finds on business websites, so it isn't in the price tables. We didn't run our own accuracy test. Prices and features come from each vendor's own pages, checked in November 2026 and linked in the Sources. Accuracy figures are the vendors' own claims.

How much do email verifiers cost per 1,000?#

Between about $1.20 and $13 per 1,000 at 10,000 emails, and between about $1.20 and $6.50 at 100,000, as of November 2026. The table uses each vendor's one-time (pay-as-you-go) price unless noted.

How to read it:

• Hunter is priced in plan credits. A verification costs half a credit, so Growth's 10,000 credits a month cover 20,000 checks. Starter ($49 a month) covers 4,000, which is $12.25 per 1,000.
• ZeroBounce ONE is a $99 monthly subscription that includes 10,000 validations and 10,000 email finder credits, $9.90 per 1,000 if you only verify.
• NeverBounce's pay-as-you-go rate is $8 per 1,000 below 10,000 emails. The Growth subscription is priced by monthly volume.
• At 1,000,000 emails, MillionVerifier lists $449 and Reoon $972.

The per-1,000 price is not the whole cost. The next two questions, what you are charged for and what happens to catch-all addresses, matter more for most B2B lists.

Which results are you charged for?#

Almost every verifier refunds unknown results. The difference is in catch-all results, the ones that can't be confirmed either way.

"Not stated" means we couldn't find it on the vendor's public pricing or docs pages. Ask before you buy if your list is mostly catch-all.

How does each verifier handle catch-all emails?#

A catch-all (or accept-all) server says yes to every address at its domain, so the normal mailbox check can't tell a real inbox from a typo. Verifiers differ in what they do next: label it and stop, add a score, or try other methods to resolve it.

Two other verifiers sell catch-all resolution as its own feature. DeBounce charges 10 credits per catch-all validation. Clearout calls its version Deep Verify. We left both out of the price table because their per-1,000 prices load only inside their calculators.

No method turns every catch-all into a certain yes. ZeroBounce's own page says some catch-all addresses "may still remain unresolved, so no validation method should be treated as a guarantee." For the background, see catch-all emails explained and how to check if an email is catch-all.

Why do catch-all addresses matter more for local-business lists?#

Because they can be a large share of the list, and they're the part a verifier can't settle. Published figures vary: Hunter found 38% of email domains in a sample of 2,572 addresses were accept-all, and MailerCheck reports a median catch-all share of 15.25% per list across its customers' lists. Those measure different things, but both say the share is high enough to change your send volume.

Local businesses add their own quirks:

• Small domains, set up once. A plumber's domain is often set up by a web designer years ago, sometimes with a catch-all so no customer email gets lost.
• Microsoft 365 and Google Workspace. Many small businesses host mail on one of the two. ZeroBounce describes specific handling for both.
• Free webmail. Many owners publish a Gmail, Yahoo or Outlook address. Reoon notes that many verifiers struggle with Yahoo, AOL and Microsoft consumer mail.
• Role addresses. info@ and office@ are often the only published address. They verify like any other address, but they may go to a shared inbox.

The practical effect: two verifiers can return very different Valid counts on the same local list, mostly because of how they treat catch-alls. That's why the test below matters more than the table above.

How do you test a verifier on your own list?#

Test on your own data. Every verifier here has free credits, which is enough for a fair side-by-side.

1. Take 300 to 500 real addresses from the list you plan to send to. Don't use a clean sample: keep the catch-alls and webmail in.
2. Run the same file through two or three verifiers using their free credits.
3. Compare four counts: Valid, Invalid, Catch-all or Risky, Unknown. A verifier with more Valid results isn't better unless those addresses really deliver.
4. Send a small test batch of 50 to 100 from the Valid group of each, from a warmed-up domain. Watch bounces for 48 hours.
5. Price each one at your real monthly volume, including what it charges for catch-all results and whether credits expire.

What is each verifier built around?#

These are facts from each vendor's own pages, not a ranking.

What about accuracy claims?#

Treat them as marketing until you test. MillionVerifier says "99%+ accuracy" and Reoon "99% accuracy". Clearout says 99.73%. None of these is an independent test, and we didn't find a public, same-list comparison of all eight. Accuracy also depends on the list: a verifier can look excellent on consumer Gmail addresses and much weaker on small business domains. The side-by-side test above is the only accuracy number that applies to your list. For what the checks actually do, see how email verification works.

Do you need a separate verifier if you build the list in Leadraft?#

No. A standalone verifier cleans a list after someone else built it. If the tool that builds the list already checks each address against the mail server and labels catch-alls separately, a second pass mostly re-confirms the same answers, and you pay twice.

Leadraft checks as it finds. It finds businesses on Google Maps, reads emails from each business's own website, and checks every address against the live mail server before it counts. Results come back as Verified, Accept-all ("a maybe, never a yes") or Invalid, which is never exported. Details are in our verification method and on the emails page.

What should you use for a local business list?#

Build it in Leadraft. The check is included, so you never buy verification credits on top of a list. Only Verified emails you take out use a checked-email credit: Starter is $19 a month for 1,000, Growth $49 for 5,000, and unused credits roll over while your plan is active. For comparison, verifying 10,000 emails from another source costs $11.90 to $129 on its own at the prices above, before you've paid for the list itself.

FAQ#

What is the cheapest email verifier?#

On list prices as of November 2026, Reoon is the cheapest per 1,000 at both 10,000 ($11.90) and 100,000 ($116.40) one-time credits. MillionVerifier is next at 100,000 ($149), and NeverBounce's Growth subscription is $159 a month for 100,000. Check whether catch-all and unknown results are charged before comparing.

What free credits do email verifiers give?#

Reoon gives 20 free verifications a day, up to 600 a month, plus 100 bonus credits at sign-up. Emailable gives 250 credits once. ZeroBounce gives 100 a month with a business domain. MillionVerifier, Bouncer and Kickbox give 100. Hunter's free plan has 50 credits a month, and a verification costs half a credit.

Can an email verifier check catch-all addresses?#

Not with certainty. A catch-all server accepts every address, so the normal mailbox check proves nothing. Some verifiers try extra methods: ZeroBounce says it resolves many addresses on Microsoft 365, Google Workspace and some security gateways, and MillionVerifier says it resolves 30% to 40% of catch-alls. Treat what is left as a maybe. More in the catch-all glossary entry.

Do email verifiers charge for unknown results?#

Most don't. ZeroBounce, Bouncer, Kickbox, Emailable, Reoon and MillionVerifier all say unknown results are free or refunded. MillionVerifier also doesn't charge for catch-alls it can't resolve. Reoon charges one credit for a catch-all result, and ZeroBounce's pricing page only exempts unknowns.

Do I need an email verifier for a local business list?#

Not if you build the list in Leadraft. It checks every email against the live mail server as it finds it, keeps catch-alls apart as Accept-all, and never exports Invalid, so the list is already graded when you download it. A standalone verifier is for cleaning a list you got somewhere else; for that job, run the same 500 addresses through a few verifiers' free credits and compare the Valid, Catch-all and Unknown counts.
