MillionVerifier pricing is pay as you go: you buy a credit pack, credits never expire, and you pay only for addresses that come back good or bad. Its price slider shows 10,000 credits for $39, 100,000 for $149 and 1 million for $449, checked October 11, 2026. Below are the details, what MillionVerifier does well, and when emailvalidation.io or another verifier is the better fit.
Disclosure: we make emailvalidation.io, one of the alternatives on this page. MillionVerifier’s strengths are listed in their own section, and the sources are at the end.

The price slider on MillionVerifier’s homepage also offers 5M, 10M, 25M and 50M credits. The billing rules:
- What you pay for: “you only pay for good and bad emails and not for risky (unknown and catch-all) emails.”
- Free credits: 100 for a new account, no credit card required.
- Expiry: “Credits never expire.”
- Refund guarantee: if “you experience a higher than 4% hard bounce rate, we refund your last payment.”
- Bonus credits: 1 million extra for every 5 million purchased (“Million Ever Green”), and 10% extra on every payment with auto top-up.
- Contracts: none; you buy credits when you need them.
Quick verdict
- Choose MillionVerifier for one large list at the lowest price per address, especially if many addresses sit on catch-all domains (they are not charged).
- Choose emailvalidation.io for verification every month through an API or in lists below 10,000 addresses, or when you want bulk jobs that call a webhook: $9.99 for 5,000 checks a month, $94.99 for 100,000.
- Choose a vendor with deliverability tools such as ZeroBounce or Bouncer if you also want inbox placement tests or monitoring.

Where MillionVerifier is stronger
- Price per address on big lists. 1 million verifications for $449 is $0.000449 per address, about 0.045 cents. Our Large plan works out to 0.095 cents per address at 100,000 a month.
- Catch-all and unknown results are free. On a B2B list where many domains accept all mail, that lowers the real cost further. We charge every successful single check; in bulk jobs we refund timeouts, not catch-all results.
- Credits never expire. Buy once and use them across years. Our plans are monthly allowances.
- A bounce guarantee. MillionVerifier refunds your last payment if verified lists bounce more than 4% hard. We make no such promise.
- Integrations and EverClean. It lists 40+ integrations, and EverClean “verifies new contacts every day inside your Mailchimp, HubSpot, or ActiveCampaign account”. We connect through the Zapier integration and the API.
- Filtered downloads. The bulk API can return only
ok,ok_and_catch_all,unknownorinvalidrows, or filter by role and free addresses.
Where emailvalidation.io is the better fit
Small and steady volume. MillionVerifier sells nothing below 10,000 credits. If you check sign-ups or a few thousand addresses a month, our Small plan covers 5,000 checks for $9.99 and the free plan 100 a month. Prices are on our email validation API pricing page.
Bulk jobs that call you back. POST /v1/bulk takes a JSON array or a CSV/TXT file of up to 100,000 addresses. When the job completes, you get one signed webhook (HMAC-SHA256), so you don’t need to poll; results come as JSON or as a CSV with your original columns plus 15 result columns. Deleting a job refunds addresses not yet verified, and a failed job is refunded in full. Large lists can take a day or longer, because checks are paced per receiving mail server. See email list cleaning service.
A response built for code. Each email validation API response has 15 fields: state, one reason such as invalid_mailbox or timeout, a score from 0 to 1, did_you_mean, and flags for role, disposable and free addresses. Only successful calls count against your quota.
Catch-all checks on request. Catch-all addresses come back as deliverable with the reason low_deliverability; send catch_all=1 for the catch_all field. Our guide to catch-all email explains how to treat them.
SDKs and AI agents. Official SDKs for JavaScript, Python and PHP, clients for Ruby, Go, C#, R, Rust and Perl, and a hosted MCP server for Claude, Cursor and other agents.
What you give up compared with MillionVerifier: the lowest price per address on very large lists, free catch-all results, credits that never expire, the bounce refund guarantee, and its integrations.
