MillionVerifier Alternatives: Pricing and Billing Compared

MillionVerifier alternatives: what does verification cost?

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

This article answers one question: if you're looking at alternatives to MillionVerifier, how do their pricing and billing rules compare? We checked each vendor's official pages on 2026-10-31. Every claim below comes from those pages. We didn't run hands-on accuracy or deliverability tests. The screenshots show what each page said when we captured it on 2026-10-31. They don't prove results.

The MillionVerifier baseline

MillionVerifier's homepage lists a 50K-email pay-as-you-go package for $89, or $0.00178 per credit. The page says credits never expire. It also lists a 100% money-back guarantee, a "risky email refund" and volume pricing above 50M. Its tools include a single-address checker, CSV list verification, a bulk verifier, an API and ESP integrations. The captured excerpt doesn't say how Unknown results are billed. A refund for risky emails is not the same as a billing rule for Unknown results.

1. FairValid

Best fit: Teams that want one-time credit packs, paid credits that don't expire, a monthly free allowance and clear charging rules for each result.

Sourced strengths:

• One-time packs cost $19.50 for 10,000 credits, $44.50 for 50,000 and $224.50 for 1,000,000, excluding tax (pricing). A one-time top-up can be any whole amount from 2,000 to 1,000,000 credits.
• Paid credits don't expire while the account remains open. Monthly plans are a separate billing choice, and you don't need one to make a one-time purchase (pricing).
• A completed Valid or Invalid result costs one credit. Unknown and unresolved Catch-all results have no net charge, and held credits are released or returned (credit rules). Pending is not a final result. Technical failures and unprocessed work also have no net charge, and FairValid doesn't relabel them as Unknown.
• If a row appears more than once in a single imported list, FairValid checks it once and maps the result back to each source row. The repeated rows aren't charged again (CSV rules). This rule covers one import only. Separate submissions and later rechecks aren't always free.
• The original account receives 300 free credits each month, and free credits are used first (credit rules).

Sourced limitations:

• Free credits don't roll over, and additional workspaces don't get their own free allowance (credit rules).
• Prices exclude tax. A subscription automatically buys its fixed credit amount every billing period (pricing).
• A Valid result never guarantees inbox delivery. Catch-all domains can make mailbox-level conclusions less certain (results guide).

Pricing compared with the baseline: FairValid charges $44.50 excluding tax for 50,000 one-time credits (pricing). MillionVerifier charges $89 for its 50K package (homepage). MillionVerifier's capture doesn't say whether that price includes tax, so your final totals may differ.

2. ZeroBounce

Best fit: Buyers who want one credit balance that works for validation, AI scoring, Email Finder and Domain Search.

Sourced strengths:

• Credits can be used for Email Validation, Scoring, Email Finder and Domain Search (ZeroBounce pricing).
• The page says credits never expire and Unknown results are free (ZeroBounce pricing). That means Unknown results aren't charged. The page doesn't say whether credits are deducted first and then returned.
• The page says all accounts include detailed status codes, an inbox placement test, an email server test, multiple API keys and 24/7 customer support (ZeroBounce pricing).
• The Freemium plan includes 100 validation credits that refill monthly. It also includes one inbox test, one email server test, one blacklist monitor and an Email Finder allowance of 10 (ZeroBounce pricing).
• ZeroBounce advertises "99.6% Validation Accuracy Guaranteed" (ZeroBounce pricing). We haven't tested this claim.

Sourced limitations:

• The minimum purchase is 2,000 credits. Above 1 million credits, you have to contact ZeroBounce for enterprise pricing (ZeroBounce pricing).
• The Freemium plan doesn't include Activity Data, Warmup or DMARC monitoring (ZeroBounce pricing).

Pricing: Pay-as-you-go pricing for 10,000 credits is $129, or $0.0129 per credit (ZeroBounce pricing). The page offers 15% off with a ZeroBounce ONE subscription. If that discount applies to this credit price, the credit subtotal would be $109.65. The capture doesn't show the price of the ZeroBounce ONE subscription itself, so the total cost of the bundle is unknown.

FairValid's 10,000-credit one-time pack costs $19.50 excluding tax (pricing). ZeroBounce's capture doesn't say whether its price includes tax. ZeroBounce's free plan includes 100 validations a month, while FairValid's original account gets 300 free credits a month (credit rules).

3. Emailable

Best fit: Teams that want the same one-credit price for bulk, single, API and widget checks, with deliverability tools in the same account.

Sourced strengths:

• Bulk, Verifier, API and Widget checks each cost one credit per verification (Emailable pricing).
• Credits never expire, and the per-credit rate drops automatically on larger purchases (Emailable pricing).
• When a list finishes verifying, credits spent on Unknown results and duplicates go back to your balance (Emailable pricing).
• Emailable says all features are included, with no paid add-ons and no long-term contracts required. Accepted payment methods include major cards and PayPal (Emailable pricing).
• Every new account starts with 250 free credits (Emailable pricing).

Sourced limitations:

• Deliverability tools use more credits: 100 per Inbox Report and 5 per Blacklist Monitor check (Emailable pricing).

Pricing: The capture lists credit tiers from 5K to 1M but doesn't show their prices, so we can't compare equivalent dollar amounts (Emailable pricing). The page says you can save 15% with a subscription. The discount percentage is stated, but the capture doesn't show the base price it would apply to.

Trade-offs to weigh

• Price at equivalent volume: For 50,000 credits, FairValid lists $44.50 (pricing) and MillionVerifier lists $89 (homepage). For 10,000 credits, FairValid lists $19.50 and ZeroBounce lists $129 pay-as-you-go (ZeroBounce pricing). Tax treatment may differ between vendors. Emailable's prices weren't visible in the capture.
• Shared features: All four vendors say paid credits don't expire, though FairValid adds the condition that the account must remain open. FairValid, ZeroBounce and Emailable all say Unknown results end up with no charge. FairValid and Emailable both cover duplicates within a list (CSV rules, Emailable pricing). Because these features are shared, they aren't an advantage for any one vendor.
• Competitor strengths: ZeroBounce's credits work across validation, scoring, Email Finder and Domain Search (ZeroBounce pricing). Emailable includes deliverability tools and returns credits for duplicates and Unknown results (Emailable pricing). MillionVerifier offers a money-back guarantee and refunds for risky emails (homepage).

A pricing page can't tell you which tool will be most accurate on your list. Testing a small batch can give you a better sense. If you'd like to try that with FairValid, its 300 free monthly credits are an easy place to start.
