MillionVerifier vs Reoon
Both are budget email verifiers with credits that never expire, and both clean a list to about the same standard. The real difference is price and what each one charges you for. Here is how they compare on cost, billing rules, free tiers, and reviews.

Same job, the call is about price
Both clean a list to roughly the same standard and both sell credits that never expire. They split on price and on what each one charges you for.
Lower headline rates at small and mid volume, a renewable free daily faucet, and a choice of one-time credits or a daily-renewal subscription. It auto-refunds unknown results.
It bills only valid and invalid results, so catch-all and unknown are free, and it is cheaper at the very top of the volume ladder. A long-time cold-email favorite for one-off bulk cleans.
- ✓Your B2B lists are full of catch-all domains
- ✓You clean very large lists in big one-off bursts
- ✓You want native integrations into your ESP and CRM
- ✓You verify at small or mid volume and want the lowest rate
- ✓You want a real free daily allowance, not a one-time trial
- ✓You prefer a daily subscription or an API-first workflow

What each tool actually is
Both do the same job: take a list of email addresses, check each one, and tell you which are safe to send to. Both advertise around 99% accuracy, which is industry parity, so the comparison below stays on price, billing rules, and free tiers, where they genuinely differ.
MillionVerifier
A bulk email verifier built around one-time credits that never expire. You upload a list, it checks each address, and it bills you only for valid and invalid results, never for catch-all or unknown. It has been a cold-email favorite for years because the cost per usable result stays low and there is no subscription to manage.

The Reoon Email Verifier is the lowest-priced verifier we would trust on a real list. It sells one-time instant credits that never expire alongside a daily-renewal subscription, and it ships a genuinely generous free tier with daily credits that renew for life. It charges one credit per successful verification and auto-refunds unknown results.

What real users say
Public review scores and the themes that come up most, checked June 2026. Counts drift, so the live links are the source of truth.
MillionVerifier
Praised for: the cheapest credible verification, credits that never expire, and only paying for valid and invalid results.
Watch-outs: real-world accuracy can fall short of the marketed 99%, support response times can lag, and the upload flow occasionally stutters on big files.
Reoon
Praised for: accuracy and reliability, ease of use, and value, especially the free daily credits and the non-expiring instant credits.
Watch-outs: on-site pricing is gated until you register, the integration story is API-first and thin on native connectors, and the Reoon brand spans several products, so match reviews to the Email Verifier.
Read the scores in context. Both are self-serve budget verifiers rated mostly by hands-on users, and we kept to one clean Capterra box each for a fair, directly-verified comparison. Reoon's higher 4.9 sits on a comparable, sizable base of 198 reviews against MillionVerifier's 100, but these tools really separate on price and billing rules more than on the score.
Where each one actually wins
Six things separate these tools in practice. Here is the honest call on each.
Headline price at low and mid volume
Edge: ReoonOn the sticker, Reoon is clearly cheaper until you reach very high volume. Ten thousand credits cost $11.90 against MillionVerifier's $37, and 100,000 cost $116.40 against $149. If you verify in the tens of thousands and your lists are reasonably clean, Reoon's rate is hard to beat. Both sell one-time credits that never expire, so neither pressures you into a subscription to get that price.
Billing rules on catch-all and unknown
Edge: MillionVerifierThis is the line that flips the naive cheaper-per-credit math. MillionVerifier bills only valid and invalid results, so catch-all and unknown cost you nothing. Reoon auto-refunds unknown results but still spends a credit on each catch-all address. On a B2B list where a fifth to a third of addresses sit on catch-all domains, MillionVerifier's effective cost can drop well below its headline rate while Reoon's stays close to list size.
Cost at very high volume
Edge: MillionVerifierThe cost lines cross as volume climbs. At a million verifications, MillionVerifier's bulk block is $549 against Reoon's $960 for the same count of one-time credits. Add the free catch-all and unknown rule on top, and MillionVerifier is the cheaper home for the big infrequent cleans that agencies and high-volume outbound teams run.
Free tier and billing flexibility
Edge: ReoonMillionVerifier gives you 100 free credits once, on signup. Reoon gives 100 instant credits plus 20 daily credits that renew for life, so a light user can keep a list clean for free indefinitely. Reoon also lets you choose between one-time instant credits and a daily-renewal subscription, which suits a steady daily trickle, while MillionVerifier is pure one-time pay as you go.
Integrations and workflow
Edge: dependsMillionVerifier ships more than 40 native integrations into ESPs and CRMs like Mailchimp, HubSpot, and ActiveCampaign, plus EverClean for automated re-verification inside those tools. Reoon is API-first with a clean developer story but fewer native connectors. If you want a verifier that drops into your existing stack, MillionVerifier fits. If you are wiring verification into your own code, Reoon's API is the cleaner path.
Accuracy
Edge: tieBoth advertise about 99% accuracy, and in real campaigns the gap is small enough that we would not pick on this. Accuracy at this level is industry parity across credible verifiers, so treat the 99% claims as table stakes from both and let price and billing rules decide. No verifier can confirm a mailbox behind a catch-all domain, which is why how each one bills that result matters more than any headline number.

One credit per successful verification. Unknown results are auto-refunded. Instant credits never expire.
True cost at scale. Reoon is cheaper at small and mid volume, 10,000 for $11.90 against $37 and 100,000 for $116.40 against $149. MillionVerifier pulls ahead at the top, where a million verifications cost $549 against Reoon's $960. And because MillionVerifier never bills catch-all or unknown, it can beat a lower headline rate on lists full of catch-all domains. Pick by your volume and how dirty your lists run, not by the entry price alone.
What neither tool does well
Both are verifiers, so they share the same blind spots. Worth knowing before you expect either to carry your whole motion.
Verification cleans a list you already have. Neither tool finds or sources new contacts, so you still need a data or finder tool upstream.
A clean list does not fix a cold sending domain. Neither tool replaces warmup, and sending hard off a fresh domain still burns reputation.
Both confirm an address exists. Neither guarantees placement. Authentication, content, and reputation decide whether you land in the inbox.

Our take, after running both
The choice is about price, billing rules, and volume, not accuracy. Here is how we'd call it in three situations.
The lower headline rate and the renewable free daily credits make Reoon the cheaper choice until you reach very high volume.
Free catch-all and unknown billing plus the cheapest rate at a million credits make it the better home for big, dirty B2B cleans.
A clean list does not fix a cold domain or guarantee the inbox. Pair either verifier with warmup and a healthy sending setup.
