Pricing
Email verification pricing, compared per address
What a thousand, ten thousand and a hundred thousand verifications cost at each vendor's own published prices — and the two columns that decide the real cost.
How this was worked out
- Each cell is the cheapest single published option that covers that many verifications. Single, because stacking two packs is usually cheaper and no vendor builds their table to be read that way — combining them would be our arithmetic rather than their price.
- The rate underneath is what the purchase works out at per 1,000 verifications if you use all of it. Buying 100,000 credits to run 60,000 checks costs what the 100,000 cost.
- Where a vendor charges half a credit per verification, that is applied. Hunter and VerifyInbox both do.
- A subscription price is marked as such. A monthly plan and a one-time pack are not the same product and the table does not pretend otherwise.
- A blank cell means the vendor publishes no price we could read at that volume. It is not an estimate and it is not a judgement about the product.
No accuracy column, deliberately. Several vendors publish an accuracy percentage. None of them, ourselves included, has published a benchmark an outsider could reproduce — the same list, the same day, the methodology stated. Ranking on unreproducible self-reported numbers would make this table worse, not more complete.

Every price read from that vendor's own page on 11 September 2026. Our own numbers are computed from the same file the checkout charges against, so this table cannot drift from what you would actually be billed.
VerifyInbox. We publish no price above the Scale plan, which is why the highest column reads worse for us than for four of the vendors below. That is the honest position, not an oversight.
Emailable. Their tier selector renders prices in the browser; only the 5,000-credit tier and the 15% subscription discount were readable in the served HTML. The rest of the ladder is not restated.
MillionVerifier. Their ladder is rendered by a calculator; the 50,000 tier was the only price in the served HTML, so the other columns are blank rather than estimated.
ZeroBounce. Two published anchors: a $39 pay-as-you-go minimum for 2,000, and ZeroBounce ONE from $99 a month with a 10,000-credit minimum. Volumes above that are not published as a table.
Snov.io. Snov credits are a single pool across finding, verifying and sending, so a credit spent verifying is one not spent prospecting. The columns below assume every credit goes to verification.
Clearout. Their pricing page describes prepaid and subscription plans but rendered no prices in the served HTML, so no Clearout price is restated here.
DeBounce. Their ladder is a slider with a "from $0.00045 per check" headline; a rate that applies at the top of the ladder is not a price at the bottom, so no DeBounce price is restated here.
NeverBounce. Their pricing page returned HTTP 403 to our fetch, so nothing about NeverBounce pricing appears in this table. The link is here so you can read it yourself.
What the table says about us
We are not the cheapest and the table shows it. At a hundred thousand addresses Bouncer and Kickbox publish a lower price than anything we quote publicly, and we publish nothing at all above the Scale plan. If the only question is cost per address at volume, buy from one of them.
We also lose the credit-expiry column outright. Five vendors here state that credits never expire; ours are granted per billing period and expire at the end of it, and packs last a year. And four of them charge nothing for a result they could not establish, where we charge for a catch-all because the probe did establish a real fact about the domain.
Where the arithmetic favours us is at the bottom of the ladder and on what comes back with a result: a free tier that renews every month rather than once, the API and bulk included in it, and the SMTP reply code, the enhanced code and a reason on every verdict. Whether that is worth a higher price at a hundred thousand addresses is a question the table lets you answer rather than one it answers for you.
The other half of this comparison is the feature one: verification services ranked on stated criteria, and every head-to-head comparison. Our own prices are on the pricing page.

Questions about verification pricing
How much does email verification cost?
Published prices in this category run from single-digit dollars per thousand addresses at volume to around $40 per thousand at the smallest prepaid tier. The number that decides what you actually pay is rarely the headline rate — it is whether unused credits expire and whether you are billed for results the vendor could not establish.
What is the cheapest email verification service?
On published prices at a hundred thousand addresses, Bouncer and Kickbox are the cheapest of the vendors whose full ladders we could read. We are not, and we do not publish a price above the Scale plan at all. If price per address at volume is the deciding factor, buy from one of them.
Do email verification credits expire?
It varies and it is rarely on the pricing page. Bouncer, Emailable, MillionVerifier, Clearout and DeBounce all state that credits never expire. Our plan credits expire at the end of each billing period and our credit packs last a year, which is worse and is in the table.
Are you charged for a catch-all or unknown result?
Kickbox refunds anything it cannot make definitive, Bouncer and ZeroBounce charge nothing for an unknown, and MillionVerifier refunds anything it cannot verify with certainty. Here a retryable result is free but a catch-all or full mailbox is charged, because the probe did establish something real about the domain. Theirs is the more generous rule.
Why do some rows have no price?
Because we could not read one. Four of these vendors render their price ladder in the browser rather than in the page, and one returns HTTP 403 to automated requests. Rather than estimate a number and attach a company name to it, those cells are blank and the row says what happened.
