What MillionVerifier is
MillionVerifier checks email addresses individually, in uploaded lists, or through connected services and API workflows. It accepts CSV, TXT, and XLSX lists, supports bulk verification and imports from email-service providers, and offers a REST API described as sub-second for signup forms. Its EverClean feature checks new contacts in connected email-service-provider accounts each day and can remove bad addresses automatically. The service advertises 99%+ accuracy, advanced catch-all checks at no extra cost, and refunds for addresses it cannot verify with certainty, including a 100% money-back guarantee for risky emails. More than 40 integrations are listed, including Mailchimp, HubSpot, ActiveCampaign, and SendGrid; custom endpoints can connect other CRMs or databases. MillionVerifier is available through web and API access and is for business, professional, trade, public-sector, or organizational use. It has a free plan and trial.
