AppSumo markets Reoon Email Verifier as the alternative to ZeroBounce, and its own page headline reads “$79 once vs ZeroBounce $240/yr”. That framing is roughly right on price and badly incomplete on everything else, because these two products are not trying to be the same thing.
Reoon verifies email addresses. ZeroBounce runs a deliverability programme. Once you see that, the price gap stops being surprising and the decision gets easy.
The short answer
- Buy Reoon if you need a list cleaned and nothing more. $79 once, 100,000 credits, plus 500 a day forever.
- Buy ZeroBounce if someone at your company owns deliverability as a job and needs warmup, blacklist monitoring, DMARC and inbox placement testing from one vendor.
- On verification cost alone, ZeroBounce is roughly 17× the price for the same volume. That is not a criticism of ZeroBounce; it is a sign you are comparing the wrong column.
Price, like for like
| Reoon | ZeroBounce | |
|---|---|---|
| Model | One-time licence (AppSumo) | Pay-as-you-go, or subscription |
| Entry price | $79 once | $0.0138 per credit, 2,000 minimum |
| Subscription option | — | ZeroBounce ONE from $99 / month, 10,000-credit minimum |
| 100,000 verifications | $79 | $1,380 |
| Ongoing allowance | 500 credits a day (182,500 / year) | None — credits are consumed |
| Free tier | None (60-day refund instead) | 100 validation credits a month |
| Top tier | $395 for 700,000 bonus credits | Contact sales above 1 million |
The daily allowance is the figure that decides most purchases and the one AppSumo’s headline leaves out. 182,500 verifications a year, free, forever. At ZeroBounce’s pay-as-you-go rate the same annual volume costs about $2,518.
If your verification need is a steady trickle rather than a bulk clean, Reoon’s recurring cost is zero and ZeroBounce’s is not. That is the whole argument, and it is decisive.
Where ZeroBounce earns its price
A review that stops at the price table is doing half the job. ZeroBounce ONE bundles things Reoon does not offer at any price:
- Warmup seeds — building sending reputation on a new domain.
- Inbox placement tests — confirming whether your mail lands in the inbox or the spam folder.
- Blacklist monitors, scanned every eight hours.
- DMARC domain monitoring.
- Email server tests.
- Email finder and domain search — finding addresses, not just checking them.
- A stated 99.6% validation accuracy guarantee.
Reoon does exactly one of the jobs on that list. If you are sending cold email at volume, the other six are not luxuries — they are how you find out your campaign is going to spam before you burn a domain, rather than after.
There is also a scale argument. ZeroBounce is a US company with enterprise pricing and a support organisation. Reoon is a one-to-ten person company founded in 2018 in Sylhet, Bangladesh. For a solo marketer that difference is invisible; for a company with a procurement process it may not be.
Where Reoon holds up
On the verification itself, Reoon is not a cut-down tool. Both products run the same category of checks, and Reoon’s are included at every tier:
- SMTP checking and MX record checking.
- MTA validation of the domain.
- Individual inbox status detection — whether that specific mailbox exists, not merely whether the domain accepts mail.
- Temporary and disposable address detection.
- Role account detection for info@, sales@ and similar.
- Verification of Gmail, Microsoft, Yahoo and custom domain addresses.
- A fast API, single or bulk checks, and a full condition report on every result.
Nothing is sent to the address during a check, so neither tool risks your sender reputation in the act of verifying.
Reoon’s integration list is short but covers the common cases: Excel, a REST API, a WordPress plugin that validates addresses at form submission, and compatibility with Zapier and Pabbly Connect. You request plugin access from support rather than downloading it.
What neither of us can tell you
Accuracy. ZeroBounce publishes a 99.6% guarantee; Reoon describes itself as the most accurate service available. Neither publishes the methodology behind the claim, and we have not run the same list through both tools.
So we are not going to rank them on accuracy, and you should be sceptical of any page that does without showing its test. If accuracy decides your purchase, run the same 1,000 addresses through both and compare the results yourself. ZeroBounce gives 100 free credits a month and Reoon has a 60-day refund window, so that test costs you almost nothing and answers the question properly.
Which should you buy?
- Do you need anything other than verification? If yes — warmup, blacklist monitoring, DMARC, inbox placement — buy ZeroBounce. Reoon cannot do those things and no saving changes that.
- If verification is the whole job, how much do you verify? Under about 15,000 a month, Reoon’s free daily allowance covers you indefinitely for $79 once.
- Do you have a large backlog to clear? Stack Reoon codes: $237 clears 360,000 in one pass, $395 clears 700,000.
- Do you need a US vendor with enterprise support? ZeroBounce. If you need an EU vendor instead, neither fits — see our alternatives comparison for the Hungarian and Polish options.
For most people reading this — a solo marketer, a freelancer, a small agency keeping lists clean — the answer is Reoon, and the $1,300 difference buys a lot of other software.

Frequently asked questions
Is Reoon cheaper than ZeroBounce?
Substantially. For 100,000 verifications, Reoon costs $79 once and ZeroBounce about $1,380 at its $0.0138 pay-as-you-go rate. Reoon also adds 500 free credits a day, which ZeroBounce has no equivalent of.
Is Reoon as accurate as ZeroBounce?
Unknown. ZeroBounce advertises 99.6% accuracy and Reoon claims to be the most accurate available; neither publishes its methodology and we have not tested them head-to-head. Both run the same categories of check — SMTP, MX, MTA, inbox status and role detection.
What does ZeroBounce do that Reoon cannot?
Warmup seeds, inbox placement tests, blacklist monitoring, DMARC domain monitoring, email server tests, and email finder or domain search. Reoon is a verification tool only.
Does ZeroBounce have a free plan?
Yes, a freemium tier with 100 validation credits a month, one inbox test, one email server test, one blacklist monitor and ten email finder lookups. Credits refill monthly and do not expire.
How much is ZeroBounce per month?
ZeroBounce ONE starts at $99 a month with a 10,000-credit minimum, bundling the deliverability tools. Pay-as-you-go is $0.0138 per credit with a 2,000-credit minimum and no subscription.
Can I use both?
Yes, and for a cold-email operation it is a reasonable setup: Reoon for bulk list cleaning at near-zero marginal cost, ZeroBounce or a dedicated tool for the deliverability monitoring Reoon does not attempt.
