MillionVerifier
MillionVerifier checks email addresses individually, in uploaded lists, through an API, or by importing from email-service providers. It accepts CSV, TXT, and XLSX lists and supports bulk verification. Its REST API is described as sub-second for signup-form checks, with global low-latency endpoints. EverClean 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 emails it cannot verify with certainty, including a 100% money-back guarantee for risky emails. It lists more than 40 integrations, including Mailchimp, HubSpot, ActiveCampaign, and SendGrid, and offers custom endpoints for connecting CRMs or databases. MillionVerifier says it is GDPR compliant, does not sell customer data, and permanently deletes uploaded and result files within one month. It is for business, professional, trade, public-sector, or organisational use. The free plan and trial are available; paid bundles start at $39, paid once for 10,000 credits, which do not expire.
