The six columns that actually decide it
Two of these are published by almost nobody: whether a result the vendor could not establish is charged for, and whether credits expire. They are what turns a price per thousand into a real cost, and they are the two rows where we do not win.
| Vendor | Free tier | Entry price | Finds addresses | Unknown reported separately | Charged for an unknown | Credits expire |
|---|---|---|---|---|---|---|
| VerifyInbox | 100 credits a month, renewing | $39 for 3,000 credits a month | Yes, with the page each address was published on | Yes — a third verdict, never folded into invalid | No when the result is retryable. Yes for catch-all and full mailboxes, where the probe did establish something | Plan credits at the end of each period; packs after 365 days |
| Hunter.io | 50 credits a month, renewing | $49 for 2,000 credits a month | Yes, with a sources array of up to 20 URLs | Yes — unknown is one of six status values | Not published on their pricing page | Not published on their pricing page |
| ZeroBounce | 100 credits a month, refilling — business or premium domain required | $39 minimum pay-as-you-go for 2,000; ZeroBounce ONE from $99 a month | Finder for a named person at a domain; no source page reported | Yes — and catch-all is a status of its own | No — unknown results and duplicates cost 0 credits | Credits don't expire while the subscription is active |
| Snov.io | 50 credits and 100 recipients, renewing every 30 days | $39 for 1,000 credits a month (Starter) | Yes; the source page for an address is not reported | Not published on the pages we read | Not published on the pages we read | Not published on the pages we read |
| Kickbox | 100 free verifications, listed in their price table | $5 for 500, or $10 for 1,000 — prepaid, no subscription | Not in their published product list | Yes — deliverable, undeliverable, risky, unknown | No — an inconclusive result is refunded | Not published on the pages we read |
| Bouncer | 100 free credits | $8 for 1,000 credits, prepaid | Not in their published product list | Yes — deliverable, risky, undeliverable, unknown | No — nor for duplicates | No — "credits never expire" |
| Emailable | 250 free credits on signup | $38 for 5,000 credits, pay-as-you-go; 15% off on subscription | Not in their published product list | Yes — deliverable, undeliverable, risky, unknown | Not published on the pages we read | No — "credits never expire", and subscription credits roll over |
| MillionVerifier | 100 free credits, no card | Prepaid credits; $89 for 50,000 on their published calculator | Not in their published product list | Three buckets — good, risky, bad | No — "full refund on any email we can't verify with certainty" | No — "buy credits once, use them forever" |
| Clearout | 100 free credits, no card | Not published as a static table — prepaid and subscription plans | Yes — Email Finder and Prospect | Not published on the pages we read | Not published on the pages we read | No — "unused credits roll over and never expire" |
| DeBounce | 100 free credits, no card | Not published as a static table — a volume calculator, "from $0.00045 per check" | Yes — Email Finder and Lead Finder | Yes — unknown results are described, alongside catch-all | Not published on the pages we read | No — "credits never expire" |
Every cell was read off that vendor's own page on 11 September 2026; each comparison page links the exact URLs. “Not published” means we could not find it on their site, not that the product lacks it. Our own numbers are computed from the same file the checkout charges against. Prices move — if something here is wrong, tell us and we will correct it.
Not in the table, and why
- NeverBounce — NeverBounce’s pricing and help pages returned HTTP 403 to us on 11 September 2026, so their current terms are not restated in this table. We do not publish a competitor’s price we have not read.
- Apollo.io — Apollo prices per seat rather than per address, so the columns here would not compare like with like — and its pricing table did not render to our fetch on 11 September 2026. Nothing about Apollo’s current pricing is restated in this table.
Who should pick whom
Each line is that vendor's own sentence from its comparison page. They are here because a list where we win eleven times out of eleven would be worth nothing to you.
- Choose Hunter.io if
- You need built-in campaigns, depend on their extension or Sheets add-on, or your buying process needs a vendor with a decade of history. Full comparison
- Choose ZeroBounce if
- Your problem is deliverability on a list you already own, and you want inbox placement testing and blacklist monitoring in the same product. Full comparison
- Choose NeverBounce if
- You clean multi-million-row lists on a schedule and need a native integration with an ESP they already support. Full comparison
- Choose Snov.io if
- You want prospecting, sending and a CRM in one subscription and are happy to trade depth in each for that. Full comparison
- Choose Apollo.io if
- You need volume, phone numbers, intent data and a sales workflow, and provenance is not something anyone in your organisation asks about. Full comparison
- Choose Kickbox if
- Verification is all you need, you buy in large one-off batches, and you want the price published before you talk to anyone. Full comparison
- Choose Bouncer if
- You want verification plus inbox placement testing and blocklist monitoring from one European vendor, and you never need to find an address you do not already hold. Full comparison
- Choose Emailable if
- You need a verifier that already has a native connector to the exact platform you use, and you want the largest possible free grant before committing. Full comparison
- Choose MillionVerifier if
- You are cleaning a very large list once, price per address is the deciding factor, and a three-bucket answer is enough for what you will do next. Full comparison
- Choose Clearout if
- You want phone numbers as well as email, you prospect from LinkedIn daily, or you need a Google Sheets add-on today. Full comparison
- Choose DeBounce if
- Price per check is the deciding factor, or you specifically want scheduled list monitoring and a separate catch-all resolution step. Full comparison
Already paying one of them?
A comparison answers “how do these differ”. If you have already decided to look elsewhere, the question is what happens on the Tuesday you switch — the export, the status mapping, and what stops working. That is a different page.
- Moving from Hunter.ioWhat carries over, and what you would give up..
- Moving from ZeroBounceWhat actually changes on the Tuesday you switch — the export, the status mapping, the three features you would lose, and the one rule where ZeroBounce is more generous..
- Moving from NeverBounceNeverBounce cleans lists.
- Moving from Snov.ioSnov bundles finding, verifying, sending and a light CRM.
- Moving from KickboxKickbox files accept-all, disposable and role addresses together as risky.
Two wider pages sit alongside these: the verification services ranked on stated criteria and pricing compared per address. Both put us where we honestly land rather than first.
Choosing between them
What is the best email verification service?
There is no single answer, and a page that gives you one is selling something. The two questions that actually separate these vendors are whether they charge for a result they could not establish, and whether your credits expire — both are in the table on this page, and almost nobody publishes them side by side.
Which email verifier is the most accurate?
Nobody in this category has published a benchmark that an outsider could reproduce, ourselves included, so any ranking on accuracy is a ranking on marketing claims. What can be compared is method: whether a result is a real SMTP conversation, whether an inconclusive answer is reported as such rather than folded into invalid, and whether the reply code behind the verdict is shown to you.
Do email verification credits expire?
It depends on the vendor and it is rarely on the pricing page. Several here state that credits never expire. Ours are granted per billing period and expire at the end of it; credit packs last a year from purchase. It is worth checking before comparing two prices per thousand, because an expiring credit is not the same product as one that does not.
Are you charged for an unknown verification result?
At several vendors, no — an inconclusive result is free or refunded. Here a retryable unknown is not charged, but a catch-all domain or a full mailbox is, because the probe did establish something real. That is a worse deal than Kickbox, Bouncer, MillionVerifier and ZeroBounce offer, and it is in the table rather than in the small print.
