Emailable Alternatives: FairValid, ZeroBounce, MillionVerifier

Emailable alternatives for small lists: what is the smallest sensible purchase?

This article is published by FairValid. FairValid is listed first by editorial preference, not an independent ranking.

If you clean only a few thousand addresses at a time, two questions matter most: how much do you have to buy, and what happens to the credits you don't use? This guide compares Emailable with three alternatives. It uses only official pages, checked and captured on 2026-11-09, and covers documented pricing and policy. We didn't run accuracy or deliverability tests. The screenshots show what each page said, not how well any tool performs.

What Emailable documents for small buyers

Emailable's pricing page lists amounts from 5K to 1M credits, with pay-as-you-go and monthly options. Here's what it says:

• New accounts start with 250 free credits, and unused credits never expire.
• Verification costs 1 credit per check through bulk, the single verifier, the API or the widget.
• Inbox reports cost 100 credits, and blacklist monitor checks cost 5 credits.
• Credits spent on Unknown results and duplicates go back to your balance when a list finishes verifying.
• The price per credit drops as volume grows, and a subscription saves 15%.

The captured text didn't include dollar prices for these amounts, so we can't compare Emailable's cost at each tier. The 15% subscription discount is stated, but without a base price we can't turn it into a dollar figure.

1. FairValid

Best fit: People with very small or occasional lists who want a free monthly allowance and paid credits that don't expire.

Sourced strengths: The pricing page includes 300 free credits each month, and free credits are used first. The same credit balance also covers FairMatch contact lookups. Under the credit rules, the original account gets the allowance each month on its signup date. It doesn't roll over, and additional workspaces don't get their own.

• Charges: A completed valid or invalid result costs 1 credit. Unknown and unresolved catch-all results have zero net charge, because held credits are released or returned. Returned credits keep their original lot and expiry rules.
• Pending results: A pending result isn't final, and a hold isn't a completed charge.
• Failures: Technical failures and unprocessed work have no net charge, and they aren't relabeled as Unknown.
• Expiry: Paid credits don't expire while the account stays open.
• Duplicates: Under the CSV rule, duplicate rows in a single imported list are checked once and mapped back to their source rows, with no extra charge for the repeats. This applies only within one import. Separate submissions and later rechecks aren't always free.

Sourced limitations: The smallest one-time pack in the active catalog is 10,000 credits. That's more than ZeroBounce's 2,000-credit minimum and Emailable's 5K option. The results guide says a valid result never guarantees inbox delivery, and catch-all domains can make a mailbox-level conclusion less certain.

Pricing: One-time prices from the active catalog, excluding tax:

• 10,000 credits: USD 19.50
• 25,000 credits: USD 29.50
• 50,000 credits: USD 44.50
• 100,000 credits: USD 74.50
• 500,000 credits: USD 149.50
• 1,000,000 credits: USD 224.50

Monthly plans are a separate option that buys a fixed number of credits each billing period. You don't need one to make a one-time purchase.

2. ZeroBounce

Best fit: Buyers who want to start below 10,000 credits, or who want validation, scoring and finder tools on one credit balance.

Sourced strengths: ZeroBounce's pricing page sets a 2,000-credit minimum, which suits small lists. Its credits work for email validation, scoring, Email Finder and Domain Search. The page also lists the following:

• Unknown results are free.
• Credits never expire. This line has an info marker whose details weren't captured.
• Detailed status codes, multiple API keys and 24/7 customer support.

The Freemium tier lists 100 validation credits that refill every month, plus 1 inbox test, 1 email server test, 1 blacklist monitor and 10 Email Finder. The page advertises "99.6% Validation Accuracy Guaranteed." That's ZeroBounce's own claim, and we didn't test it.

Sourced limitations: For 10,000 credits, the page shows $129, or $0.0129 per credit. FairValid's one-time price for the same amount is USD 19.50, excluding tax. The ZeroBounce capture doesn't say whether its price includes tax. The two vendors' credits also cover different extra services. The Freemium overview says activity data isn't included and that there's no access to Warmup or DMARC monitoring.

Pricing: The page offers 15% off with a ZeroBounce ONE subscription. If that discount applies to the 10,000-credit price, the credit subtotal comes to about $109.65. The page doesn't state any separate subscription fee or total bundled cost. For more than 1 million credits, ZeroBounce asks buyers to contact it for enterprise pricing.

3. MillionVerifier

Best fit: Buyers verifying around 50,000 addresses who value a stated money-back guarantee and refunds for risky emails.

Sourced strengths: MillionVerifier says its credits never expire and that it requires no contracts. It lists a 100% money-back guarantee and a "risky email refund." Its tools include a single email checker, CSV list verification, a bulk verifier, an API and ESP integration imports. The page says volume pricing is available above 50M.

Sourced limitations: The capture shows a 50K package and a "See all packages" link, but the other packages and their prices weren't captured. The captured page also doesn't describe how Unknown results are billed. The risky-email refund is a separate policy, so we don't treat it as Unknown-result billing.

Pricing: 50K emails cost $89, or $0.00178 per credit. FairValid's one-time price for 50,000 credits is USD 44.50, excluding tax. The MillionVerifier capture doesn't say whether its price includes tax.

How to choose for a small list

• About 300 or fewer credits a month: FairValid's free monthly allowance may cover you, though it doesn't roll over. It's larger than ZeroBounce's 100 monthly Freemium validation credits and Emailable's 250 credits for new accounts.
• Buying a small amount: ZeroBounce's 2,000-credit minimum and Emailable's 5K option let you buy less than FairValid's smallest pack. We have matching-quantity prices for two comparisons: 10,000 credits against ZeroBounce and 50,000 against MillionVerifier. In both, FairValid's one-time prices are lower. Tax treatment and included services may differ.
• Expiry, Unknown results and duplicates: All four vendors say their credits don't expire, though some add caveats. FairValid, Emailable and ZeroBounce all describe Unknown results as free or returned. FairValid and Emailable both describe handling for duplicates. None of these is a clear advantage for any one vendor.

Pricing and policies change, so check current terms and tax at checkout. If a free monthly allowance and one-time packs that don't expire fit how you work, you can review FairValid's current pricing and try it on a sample list first.
