FairValid vs MillionVerifier: Small Lists and Minimum Purchases

The question: what does a small list actually cost?

If you only need to check a few thousand addresses, or your list rarely grows, the smallest purchase you can make matters as much as the per-credit rate. This comparison looks at that one question for FairValid and MillionVerifier. We checked both official pages on November 11, 2026.

FairValid publishes this article. We list FairValid first because we prefer to, not because of any independent ranking. Everything below comes from captured official pages. We did not run hands-on accuracy or deliverability tests, and none of the screenshots show how either service performs on a real list.

FairValid's entry point and small-list rules

FairValid's pricing page lists its smallest paid pack at 10,000 credits for USD 19.50 as a one-time purchase. The larger one-time packs are 25,000 credits for USD 29.50, 50,000 for USD 44.50, 100,000 for USD 74.50, 500,000 for USD 149.50 and 1,000,000 for USD 224.50. These prices exclude tax. Monthly plans are a separate billing choice, and you don't need a subscription to make a one-time purchase.

For very small lists, the same pricing page says every account gets 300 free credits each month. Free credits are used first, and they don't roll over. The credit rules add more detail: the original account receives the allowance on its signup date, and additional workspaces get no extra free allowance. Paid credits don't expire while the account stays open.

What a FairValid credit pays for

Under the credit rules, a completed Valid or Invalid verification result costs one credit. Unknown results and unresolved Catch-all results have zero net charge, and any credits held for them are released or returned. Pending is not a final result, and the pricing page says a hold is not a completed charge. Technical failures and unprocessed work also have no net charge, and they are not relabeled as Unknown.

The results guide says results are evidence, not a delivery guarantee. A Valid result never guarantees inbox delivery. Catch-all domains may accept many addresses, so a mailbox-level conclusion can be less certain for them.

Small lists are often messy. The CSV rule says duplicate rows within one imported list are checked once, and the result is mapped back to each source row with no extra charge for the repeats. This applies only within a single import. It does not mean separate submissions or future rechecks are always free.

MillionVerifier's captured pricing

MillionVerifier's homepage features a 50K-email package for $89, shown as $0.00178 per credit. The page links to a full package list ("See all packages"), but our capture doesn't include it. That means we can't confirm MillionVerifier's smallest available purchase, and we make no claim about it. The page also says credits are bought once and never expire, and that there are no contracts.

Where FairValid has an evidenced advantage

The only quantity that appears in both captures is 50,000. At that size, FairValid's one-time 50,000-credit pack costs USD 44.50 before tax. MillionVerifier's 50K package is shown at $89. By the captured list prices, FairValid's pack costs half as much at this quantity.

Some caveats apply:

• MillionVerifier's capture shows dollar prices but doesn't name the currency or say whether tax is included. FairValid's prices exclude tax.
• The two services may not count credits the same way. For verification, FairValid charges one credit only for completed Valid or Invalid results. Beyond what its homepage shows, we don't know how MillionVerifier counts credits.
• A lower list price doesn't mean better quality. We have no test data comparing how accurate the two services are.

FairValid also documents a 10,000-credit one-time pack and a free monthly allowance. We didn't capture MillionVerifier's full package list, so we don't count either of these as a proven advantage over MillionVerifier.

Shared ground, not advantages

Both services say purchased credits don't expire. FairValid's rule applies while the account remains open, and MillionVerifier's homepage says its credits "never expire." Based on these captures, neither service has an edge on expiry.

Where MillionVerifier may fit better

MillionVerifier's homepage lists a 100% money-back guarantee and a risky-email refund. It also lists a single email checker, CSV list verification, a bulk verifier, an email verifier API, ESP integrations import, and volume pricing above 50M. If a money-back guarantee or importing from an ESP integration matters to you, those are real points in its favor.

MillionVerifier's risky-email refund is not the same thing as FairValid's Unknown and Catch-all billing. The captured page doesn't say how MillionVerifier handles unknown results, so we draw no conclusion there. The homepage also shows ratings and customer quotes. We haven't verified them, and they don't tell you how either service will perform on your list.

How to decide for a small list

• Price at 50,000: Compare FairValid's USD 44.50 one-time pack with MillionVerifier's $89 package, and check currency and tax at checkout.
• Lists under 50,000: Check MillionVerifier's full package list yourself before you compare. On FairValid, the 300 monthly free credits or the 10,000-credit pack may be enough.
• Guarantees: If a money-back guarantee matters, MillionVerifier states one.
• Testing: Run a sample of your own list through whichever service you're considering before you buy a larger pack.

If FairValid's pricing fits your list size, you can start with the monthly free credits. You can see the current quote and tax on the pricing page before you buy.
