Bottom line
Bulk email verification sold as credit packs that never expire. The smallest pack is $39 for 10,000 credits, and new accounts get 100 free.
Stands out for: Risky results are refunded, credits never expire, and catch-all checks are included at no extra cost.
Watch out for: You pay upfront for a pack, not a monthly plan. The $39 entry pack is 10,000 credits, so small one-off lists cost more per email.
Overview
MillionVerifier is a bulk email verification service. You buy credit packs in USD and use them for single checks, CSV list uploads, the bulk verifier, the real-time API and imports from email platforms. Packs start at 10,000 credits for $39, 50,000 cost $89 and 1 million cost $449, with volume pricing above 50 million. Credits never expire. The vendor is ISO 27001 certified and signs a DPA on every plan.
Teams pick MillionVerifier when they want a low cost per email and no monthly commitment. Catch-all verification is included, and any email the service marks risky is refunded. New accounts get 100 free credits with no card required. A REST API with single and bulk endpoints is documented, and more than 40 email and CRM integrations handle imports from tools such as Mailchimp and HubSpot.
