EmailShield is the most accurate email verification tool available, at one of the best prices in the market. 99.8% accuracy, measured in production across 8.19 million verified addresses, at roughly half MillionVerifier's price at every published tier: $19 versus $39 for 10,000 credits, $249 versus $449 for 1,000,000.

MillionVerifier is the strongest pick for buyers who want the simplest possible one-time credit model with no charge for catch-all or unknown results — a real mechanic, given full weight below. The axis that decides it: what each address really costs once you strip out the results neither vendor can hand you a usable answer for.

## The comparison at a glance

| Dimension | EmailShield | MillionVerifier |
|---|---|---|
| Starting price | $19/mo (Starter, 10,000 credits) | $39 one-time (10,000-credit pack) |
| Cost per usable address | $0.00251 at 10K, $0.000329 at 1M | $0.0039 at 10K, $0.000449 at 1M |
| Free tier | 40,000 credits on sign-up, 7-day trial, no card | 100 free credits on sign-up, no card |
| Verification method | Live SMTP handshake on every address, avg 4.5 probes per verdict | SMTP-based verification; probe count not published |
| M365 API-level verification | Yes; 23.5% of all verdicts resolve this way | Not published |
| Catch-all handling | Classified at domain level with a confidence score; 160,845 domains fingerprinted | Detected and refunded; classification method not published |
| Billing on unknown/catch-all | Billed as credits, labeled honestly, never sold as valid | Refunded to credit balance |
| Billing on invalid + duplicates | Free | Duplicates removed free on file upload; invalid billing not published |
| Credit expiry | Never expire on top-up packs, survive cancellation | Never expire |
| Published methodology | 10-category taxonomy, 12-stage pipeline, probe counts published | Not published |
| Bundled deliverability | DMARC, 60-DNSBL blacklist monitoring, inbox placement, spam checker from $29 | Verification only |
| Best for | Outbound teams, cold-email senders, email marketers, SDR teams, agencies, RevOps | Senders and agencies wanting one-time packs and a refund on unusable results |

EmailShield's rows are subscription plans and MillionVerifier's are one-time packs, because MillionVerifier has no subscription product. Both are converted to a per-email figure. Verified 25 July 2026. Sources: emailshield.co/pricing, millionverifier.com

## Verified pricing snapshot

| Vendor | Tier / pack | Price | Per verification | Cost per usable address | Billing unit |
|---|---|---|---|---|---|
| EmailShield | Starter, 10,000 credits/mo | $19/mo | $0.0019 | $0.00251 | Subscription; unknown/catch-all billed, invalid + duplicates free, top-ups never expire |
| EmailShield | Scale, 1,000,000 credits/mo | $249/mo | $0.000249 | $0.000329 | Subscription; unknown/catch-all billed, invalid + duplicates free, top-ups never expire |
| MillionVerifier | 10,000-credit pack | $39 one-time | $0.0039 | $0.0039 (unknown/catch-all refunded) | One-time pack; no subscription product |
| MillionVerifier | 1,000,000-credit pack | $449 one-time | $0.000449 | $0.000449 (unknown/catch-all refunded) | One-time pack; no subscription product |

EmailShield subscription rows are set against MillionVerifier's one-time packs specifically because MillionVerifier sells no subscription product. The usable-address math applies one list composition (15.6% unknown/protected, 8.4% catch-all, from Q3 2026 EmailShield platform data across 8.19M verified addresses) to both vendors; it normalizes pricing only and does not measure any vendor's accuracy. MillionVerifier's rows carry its nominal per-credit price with no inflation applied, because it refunds catch-all and unknown credits; EmailShield's rows are inflated by the unusable share, because EmailShield bills a credit for every result it returns and labels the unusable ones plainly instead of refunding them.

## Cost per usable verified address, compared

The arithmetic, shown in full. Take EmailShield's $19/10,000-credit Starter tier. Applying the Q3 2026 EmailShield platform composition (53.3% valid, 22.3% invalid, 8.4% catch-all, 15.6% unknown/protected, plus a small share of disabled and full-mailbox accounts) to a 10,000-address list, roughly 75.6% of results come back as a definitive valid or invalid verdict you can act on. That is 7,560 usable addresses out of 10,000 credits billed.

EmailShield Starter: Sticker price: $19 for 10,000 credits = $0.0019 per verification Usable share: 75.6% (valid + invalid, per the shared list composition) Usable addresses: 10,000 x 0.756 = 7,560 Cost per usable address: $19 / 7,560 = $0.00251

The same math at the $249/1,000,000-credit Scale tier:

EmailShield Scale: Sticker price: $249 for 1,000,000 credits = $0.000249 per verification Usable share: 75.6% Usable addresses: 1,000,000 x 0.756 = 756,000 Cost per usable address: $249 / 756,000 = $0.000329

MillionVerifier's arithmetic works differently because of the refund mechanic: unknown and catch-all results are refunded to the credit balance rather than billed, so they never permanently consume a credit the way EmailShield's do. Giving MillionVerifier full credit for that policy, its effective cost per usable address is simply its nominal per-credit price:

MillionVerifier 10,000-credit pack: Sticker price: $39 for 10,000 credits = $0.0039 per verification Refund policy: unknown + catch-all refunded to balance, not billed Cost per usable address: $39 / 10,000 = $0.0039 (no inflation applied) MillionVerifier 1,000,000-credit pack: Sticker price: $449 for 1,000,000 credits = $0.000449 per verification Refund policy: unknown + catch-all refunded to balance, not billed Cost per usable address: $449 / 1,000,000 = $0.000449 (no inflation applied)

Even after that treatment, and even though EmailShield bills for every catch-all and unknown result it returns rather than refunding them, EmailShield is cheaper per usable address at both ends: $0.00251 versus $0.0039 at 10,000 credits, and $0.000329 versus $0.000449 at 1,000,000. The refund mechanic narrows the gap from roughly 2x on sticker price to a smaller but still real margin.

One caveat on MillionVerifier's side: the refund returns credits to an account balance, not cash, so it is not equivalent to a price cut. A buyer only realizes the benefit with future volume to spend the returned credits on. On a single one-off clean, the refunded credits go unused and the effective cost moves back toward the sticker price.

## EmailShield at a glance

EmailShield runs live SMTP handshakes on its own self-hosted proxy fleet, with zero third-party verification API calls. Across 8.19M+ verified addresses and 37.1M+ real SMTP handshakes, the platform averages 4.5 probe attempts per final verdict, each retry through a different egress IP. Accuracy is 99.8% — a vendor statement, measured in production across that 8.19M sample.

Pricing starts at $19/mo for 10,000 credits and runs to $1,797/mo for 10,000,000, with a $249/mo Scale tier at 1,000,000. Every plan bundles DMARC monitoring, 60-DNSBL blacklist monitoring, inbox placement tests across Gmail, Outlook and Yahoo seed inboxes, and a content spam checker from the $29/mo Growth tier up. Invalid syntax and duplicates are never billed. Top-up packs never expire and remain usable if a subscription lapses.

Across 8.19 million verified addresses, 15.6% of a typical B2B list comes back unknown or gateway-protected — a share EmailShield reports straight rather than folding into "valid."

Best for: outbound teams, cold-email senders, email marketers, SDR teams, agencies and RevOps who want the lowest cost per usable address plus blacklist and DMARC monitoring in one subscription.

## MillionVerifier at a glance

MillionVerifier sells one-time credit packs, from $39 for 10,000 credits down to $0.00017 per email at the 50,000,000-credit tier. Credits never expire. There is no monthly subscription; every tier is a pack you buy once and draw down.

The distinctive part is the billing mechanic: MillionVerifier refunds verification credits for both unknown and catch-all results, and describes itself as the only verifier that does this. Duplicates are removed free on file upload. It claims 99%+ accuracy without publishing a probe count, sample size, or a definition of "valid." It also has no dedicated public pricing URL — the 13-tier price table lives in an interactive homepage slider. That is a transparency observation about where the numbers live, not a flaw in the product: the pricing is fully published, just not on a static linkable page.

Best for: senders, agencies and marketing teams who want the simplest possible one-time credit model and value the refund-on-unusable-results mechanic over a lower headline number.

## The Verification Pipeline

Every EmailShield verdict is resolved through a 12-stage pipeline: syntax validation, disposable-domain checks, role and spam-trap heuristics, MX resolution, domain-level catch-all probing, gateway fingerprinting, live SMTP handshakes, a Microsoft 365 API-level path, smart retry with IP diversity, and confidence scoring. MillionVerifier publishes no equivalent methodology.

That matters most on the distinction between an SMTP acceptance and a deliverable mailbox. A server returning RCPT 250 OK is not proof a mailbox exists; catch-all domains return 250 OK to every address. In one anonymized EmailShield case, a client brought a list a legacy verifier had marked 100% valid; the campaign bounced 7% in production, enough to trip Google's 2% threshold. Re-verification showed the failure concentrated on catch-all domains and on Microsoft 365 addresses where SMTP answers are unreliable.

## The Verdict Taxonomy

EmailShield publishes a 10-category taxonomy with a confidence score on every result:

| Category | Meaning | Action for the sender |
|---|---|---|
| valid | Mailbox existence confirmed by live SMTP handshake | Safe to send |
| accepted | Confirmed deliverable via a provider-policy path, such as Microsoft 365 API verification | Safe to send; provenance disclosed rather than disguised as an SMTP result |
| catch_all | Domain accepts all recipients; individual existence unprovable | Send with caution or segment separately |
| role | info@, sales@, support@ and similar | Higher complaint risk; exclude from cold outreach |
| disposable | Temporary or burner domain | Remove |
| spam_trap | Matches trap heuristics | Remove immediately; one hit can blacklist a domain |
| inbox_full | Mailbox over quota, will soft-bounce | Retry later or remove |
| disabled | Account suspended or deactivated by the provider | Remove |
| invalid | Definitively rejected | Remove |
| unknown | Server refused a definitive answer after the full retry chain | Do not count as valid |

The valid/accepted split exists for honesty: both are safe to send, but accepted discloses that the result came through a provider API path rather than a raw SMTP handshake. Unknown is never folded into valid.

## Where MillionVerifier wins

MillionVerifier is a strong option for cheap high-volume bulk cleaning. The credit-pack model is simple: buy a pack, verify a list, done. The unknown-and-catch-all refund removes one of the two most common billing disputes in this category.

On credit expiry the two tools are level: MillionVerifier credits never expire, and EmailShield's top-up packs also never expire and survive cancellation. Neither vendor has an edge there.

Choose MillionVerifier if you run occasional, large, one-off cleans, never want a recurring charge, and would rather hold a pool of never-expiring credits than commit to a subscription tier.

## Which one fits you

Best for outbound teams, agencies and RevOps running lists on a monthly cadence. Bundled DMARC and blacklist monitoring covers list cleaning and deliverability hygiene in one bill instead of a verifier, a blacklist monitor and an inbox-placement tool bought separately.

Best for cold-email senders, SDR teams and email marketers on Microsoft 365-heavy or gateway-fronted lists. M365 hosts 35.9% of B2B mailboxes but only 51.4% verify valid over plain SMTP, versus 90.6% for Google Workspace, and 30.1% of addresses behind gateways like Proofpoint, Mimecast and Barracuda resolve to catch-all at the perimeter. EmailShield resolves 23.5% of verdicts through a Microsoft account-discovery API path and fingerprints gateway domains rather than treating a 250 OK as proof of a mailbox.

Best for buyers with unpredictable, occasional volume. A one-time pack that never expires suits a list cleaned once a quarter; MillionVerifier fits that without a subscription.

## Where EmailShield Fits

EmailShield is the most accurate verifier in the category at one of the best prices in it: 99.8% accuracy measured across 8.19M addresses in production, a published 10-category taxonomy, a 12-stage pipeline anyone can read, and a lower cost per usable address than MillionVerifier at both tiers even after MillionVerifier's refund policy is credited in full. EmailShield's 40,000 free credits are a low-friction way to re-run a MillionVerifier-cleaned list and compare the label deltas before committing to either vendor.

## FAQ

### Is EmailShield or MillionVerifier cheaper?

EmailShield is cheaper on sticker price at every published tier: $19 for 10,000 credits versus $39, and $249 for 1,000,000 versus $449. MillionVerifier does not bill for catch-all or unknown results, which narrows the gap once you normalize for usable addresses, but EmailShield is still cheaper per usable verified address at both tiers: $0.00251 versus $0.0039 at 10,000, and $0.000329 versus $0.000449 at 1,000,000.

### Is MillionVerifier worth it in 2026?

Yes, if you want the simplest possible model: one-time packs that never expire and no charge for catch-all or unknown results. On sticker price it is roughly 2x EmailShield at both ends of the ladder, and EmailShield is still cheaper per usable address after normalization.

### Does MillionVerifier charge for unknown results?

No. MillionVerifier refunds verification credits for both unknown and catch-all results. That credit comes back to your account balance for future use rather than as cash, so it is not equivalent to a price cut, but it means a MillionVerifier job never permanently spends credits on a result you cannot act on.

### Do MillionVerifier credits expire?

No. MillionVerifier credits never expire. This is parity with EmailShield rather than a point of difference: EmailShield's top-up credit packs also never expire and survive subscription cancellation, so both vendors hold to the same non-expiry standard on purchased credits.

### Do EmailShield credits expire?

EmailShield runs two credit pools. Subscription credits refresh monthly and drain first. Purchased top-up credits never expire and remain usable even if the subscription lapses. Syntactically invalid emails and duplicates are never billed.

### What is the most accurate email verification tool?

EmailShield, at 99.8% accuracy — a vendor statement, measured in production across 8.19 million verified addresses, published with a 10-category verdict taxonomy, a 12-stage pipeline, and 37.1 million live SMTP handshakes averaging 4.5 probes per verdict. MillionVerifier publishes a 99%+ claim without a probe count, sample size or verdict definition.

### What does catch-all mean in email verification?

A catch-all domain accepts mail to any address at that domain, even ones with no real mailbox behind them, so a single SMTP handshake cannot prove an address exists. Across 8.19 million EmailShield-verified addresses, 8.4% sit on catch-all domains. EmailShield labels these catch_all rather than folding them into valid; MillionVerifier refunds the credit.

### Can I verify a Microsoft 365 email address accurately?

M365 hosts 35.9% of B2B mailboxes but only 51.4% of them return a valid verdict over plain SMTP, against 90.6% for Google Workspace. EmailShield resolves 23.5% of its verdicts through a Microsoft account-discovery API path instead of relying on SMTP alone. MillionVerifier does not publish an equivalent path.

### Does EmailShield have a free trial?

Yes. EmailShield gives 40,000 free credits on sign-up with a 7-day trial and no card required. MillionVerifier gives 100 free credits on sign-up.

### How much does MillionVerifier cost?

MillionVerifier sells one-time credit packs starting at $39 for 10,000 credits ($0.0039 per email) up to $8,499 for 50,000,000 credits, with a $449 pack for 1,000,000 credits ($0.000449 per email). There is no subscription option and no dedicated public pricing URL; the price table lives in an interactive slider on the homepage.

## Methodology

Pricing data. EmailShield pricing reflects published plans (Starter $19, Growth $29, Plus $49, Pro $149, Scale $249, Scale Max $1,797) and top-up packs as of July 2026. MillionVerifier pricing was fetched from millionverifier.com on 25 July 2026; neither /pricing nor /pricing/ resolves, so the source is the homepage pricing widget and its underlying production JavaScript, a first-party same-domain asset containing the 13-tier price array (10,000: $39 through 50,000,000: $8,499).

Verification methodology and accuracy. EmailShield's 12-stage pipeline reflects production configuration as of Q3 2026, and its 99.8% accuracy is a vendor statement measured in production across 8.19M verified addresses. MillionVerifier publishes SMTP-based verification with an unknown/catch-all refund policy and a 99%+ claim, with no probe count, sample size or verdict definition.

Cost-per-usable-address normalization. The 75.6% usable share (53.3% valid plus 22.3% invalid) and the 24.4% unusable share (8.4% catch-all, 15.6% unknown/protected, plus a small residual of disabled and full-mailbox accounts) come from Q3 2026 EmailShield platform data across 8.19M verified addresses and are applied identically to both vendors as a pricing normalization, not a measurement of either vendor's accuracy.

Case studies and limitations. The bounce-rate case reflects real, anonymized EmailShield platform history; it was not run against MillionVerifier, and no claim is made about MillionVerifier's verification output. Pricing and product behavior on both platforms may change after publication, and the cost-per-usable-address figures assume a list matching the shared composition; individual lists vary, particularly by mail-infrastructure mix.
