Reoon vs MillionVerifier: Two Affordable Verifiers, Compared Properly

The short answer on Reoon vs MillionVerifier: both are real, capable services at prices that will not frighten a small business, and the choice comes down to how much you clean and how often. MillionVerifier has the better number for one very large job. Its pricing slider lists 1,000,000 verifications for $449, which works out to about $0.45 per 1,000, and it refunds anything it cannot verify with certainty. Reoon is built for repeat use: free credits every day for life, purchased credits that never expire, a live API that answers in about half a second, and a deeper checking mode for awkward addresses. One big annual clean points to MillionVerifier. Verification as an everyday habit points to Reoon.

What follows is the detail behind that verdict, with every figure taken from the two companies’ own public pages and labeled as of September 2026.

First, the disclosure

We make Reoon Email Verifier. Read this page with your guard up.

Here is how we have tried to earn the read anyway. Every fact below comes from a public page on one of the two vendors’ own websites, read on September 22, 2026. Where MillionVerifier is stronger we say so in the same plain words we use for our own features, including the place where its price beats ours outright. Where a number could not be confirmed on a live page, we dropped it rather than fill the gap from memory. We used the same method when we compared two verifiers that are not ours at all, and it matters more here because this time we have money riding on your decision.

What this is not: a controlled accuracy test. Nobody has run a public, audited head to head on these two, and a vendor grading itself would not be worth much anyway. More on that below.

Four terms first, since not everyone lives in this world. A credit is one verification of one address. A catch-all domain accepts mail for any name at that domain, real or not, which makes single addresses there hard to judge. An API lets your own site or software ask the service about an address and get an answer back immediately, which is how you stop bad addresses at your signup form. An ESP is an email service provider such as Mailchimp or HubSpot, where your list lives.

One caveat on that price row. MillionVerifier uses a slider rather than a printed table, and the two volume points we could read cleanly on it were 50,000 for $89 and 1,000,000 for $449. Its per-1,000 rate falls as you drag the slider right, so move it to your own volume before deciding anything.

What you actually get for a credit

Both services do the same core work: check that the domain exists and accepts mail, open a conversation with the receiving mail server, and decide whether the specific mailbox is there, all without sending your contact an email.

The visible difference is how much of that reasoning each one hands back to you. MillionVerifier compresses the outcome into three buckets, Good, Risky and Bad, and that is a deliberate design choice rather than a shortcoming. Most people uploading a list want to know which rows to delete, and three buckets answers that in about two seconds. Reoon reports the underlying categories separately (safe, invalid, catch-all, unknown, disposable, role, spam trap or complaint) and adds an AI score out of 100 per address, which helps if you want to treat role addresses differently from catch-alls, or feed results into your own rules.

Reoon runs two modes: Quick Mode for the fast pass, Power Mode for the deeper one, where catch-all domains and other stubborn cases get worked on properly. MillionVerifier states that advanced catch-all verification is included at no extra cost, the same promise expressed as pricing rather than as a mode.

On uncertain results both take the customer’s side, by different mechanics. Reoon does not charge a credit for an unknown result at all. MillionVerifier charges and then refunds: “Full refund on any email we can’t verify with certainty,” backed by a money-back guarantee on risky emails. The refund is the broader promise, since it covers results you were handed and could not use. Not being charged is simply less to chase.

Where MillionVerifier pulls clearly ahead is living inside the tools you already use. Forty-plus integrations, and EverClean running verification daily inside your connected platform, means a team whose list lives in Mailchimp or HubSpot can set list hygiene up once and stop thinking about it. Reoon has no equivalent scheduled feature. Its answer to the same problem is the API at the point of entry: check the address when someone types it into your form, so the bad ones never enter the list. Both approaches work. They just clean at opposite ends of the pipe.

Two smaller points in MillionVerifier’s favor. Its published support is 24/7 chat plus humans during working hours, which is more than Reoon publishes. And every account includes lifetime access to its EmailAcademy PRO material, which has value even if you never use the verifier again.

The two pricing shapes

Most comparisons reduce this to a single per-email number, which hides more than it shows. The two services are not shaped the same way, so that number changes meaning depending on your habits. We wrote a longer piece on how email verification pricing actually works if you want the general version.

MillionVerifier sells blocks. You buy credits, they never expire, and the more you buy at once the less each one costs. 50,000 for $89 is $1.78 per 1,000. 1,000,000 for $449 is about $0.45 per 1,000. That is a big drop, and it tells you exactly who the pricing is designed for.

Reoon sells blocks too, and also a tap. The instant credit packs, as published in September 2026, run 10K for $11.90, 25K for $29.66, 50K for $58.95, 100K for $116.40, 500K for $522.00 and 1,000K for $960.00. Those never expire either. The second option is a daily-credit subscription starting at $9 a month for 500 credits a day, where the credits refresh every morning and unused ones do not carry over. For a business verifying a trickle of signups rather than a stockpile, paying by the day rather than by the block is a different kind of sense, and $9 a month is a low bar to test that on.

The free tiers differ in kind as well as in size. MillionVerifier gives 100 free credits with no card. Reoon gives 20 credits a day for life, up to about 600 a month, plus 100 instant credits at signup, also with no card. A one-time allowance is for evaluating; a daily one is for using indefinitely at small scale. If that matters to you, we keep a running list of verifiers that give free credits.

Where MillionVerifier costs less, plainly

At one million verifications, MillionVerifier is the less expensive option and it is not close: $449 against $960, or about $0.45 per 1,000 against $0.96 per 1,000. If your job is a single enormous clean, that difference buys a decent laptop, and no amount of feature talk from us cancels it out.

Further down the scale the picture turns around. At 50,000, MillionVerifier’s slider showed $89 while Reoon’s printed pack is $58.95. We could not read MillionVerifier’s exact 10,000 and 100,000 prices off the slider with confidence, so we will not invent them. Check those points yourself if that is your range.

Our pitch has never been the lowest price, and the numbers at the top end confirm that. What Reoon aims at is capability you would expect from an expensive tool at a rate a small business can live with, with the running costs (expiring credits, charges for results you cannot use) taken out.

About those 99% claims

Both services advertise 99% or better. Both figures are self-reported, as is every accuracy number in this industry, because there is no independent auditor checking any of them. Treat all of them, ours very much included, as a statement of intent rather than a measurement.

The only test with any authority is the one you run on your own list, because your own domains and your share of catch-all addresses move the result far more than any vendor’s lab conditions. We published a one hour method for testing verifier accuracy on your own data, and it works on any provider, including both of the ones in this post. Both give you free credits precisely so you can do this, so use them on the same sample and compare the two answer sheets.

Who should pick which

MillionVerifier is the better fit when:

• You have one very large list to clean, especially at the million mark where its price is roughly half.
• Your list lives in Mailchimp, HubSpot or ActiveCampaign and you want EverClean keeping it tidy daily without anyone remembering to do it.
• You want three simple buckets and no interpretation work.
• A refund guarantee on uncertain results is the reassurance you want in writing.
• You value round-the-clock chat support, or the EmailAcademy material that comes with the account.

Reoon is the better fit when:

• Your verification is a steady trickle rather than an annual event, and a daily credit allowance fits that shape better than a stockpile.
• You want to stop bad addresses at the form with a live API instead of cleaning them out later.
• You are working with smaller or mid-size lists where the printed pack prices land well.
• You want the detail behind the verdict: catch-all, role, disposable and spam trap flagged separately, with a score you can build rules on.
• You want to test properly on your own data first, at no cost and for as long as you like.

If you run a WordPress site collecting signups through forms, the form validation plugin does that job without anyone writing code.

Try it on your own list before you pay either of us

The honest close to a vendor-written comparison is not “buy ours.” It is this: take 500 real addresses from your own list, run them through both services, and look at where the two disagree. That sample costs nothing on either side and tells you more about your own data than this page can.

If you want to start with ours, you can create a free Reoon account with no card, use the free daily credits, and have your sample back in a few minutes.
