What MillionVerifier is
MillionVerifier checks email addresses individually, in uploaded lists, and through connected services. It supports CSV, TXT, and XLSX files, bulk verification, imports from email-service providers, and API checks. Its REST API is described as sub-second for signup forms, with low-latency endpoints worldwide. EverClean checks new contacts in connected provider accounts daily and can remove bad addresses automatically. MillionVerifier advertises 99%+ accuracy, includes advanced catch-all checks at no extra cost, and says it refunds emails it cannot verify with certainty, with a 100% money-back guarantee for risky emails. It lists more than 40 integrations, including Mailchimp, HubSpot, ActiveCampaign, and SendGrid, and custom endpoints can connect other CRMs or databases. The service has web and API access and is intended for business, professional, public-sector, trade, or organizational use. A free plan and trial are available. Credit bundles start at $39, paid once; purchased credits never expire.
