MailVeri

MailVeri is an email verification service for marketers, outreach agencies and developers. Upload lists of up to 1,000,000 emails (CSV, XLSX, TXT) or call the REST API for sub-second checks. Every address gets deep SMTP verification plus catch-all, disposable and role-account detection, so you only send to real inboxes and protect your sender reputation. An open-source MCP server lets Claude, Cursor and other AI agents verify emails directly. Pricing is pay-as-you-go from $9 per 10,000 credits, credits never expire, there is no subscription, and you get 1,000 free credits on signup with no card required.
