Mailsfinder is a B2B email discovery and verification platform designed to help sales, marketing, and growth teams find professional contact details and manage outbound prospecting more efficiently. Its tools support SaaS and technology companies, agencies, SDR and BDR teams, founders, and other go-to-market professionals. Users can find business emails by name and domain, search from LinkedIn profiles or Sales Navigator, look up individual addresses, and enrich or verify contact lists in bulk. The platform also offers free email lookup and verification tools, including reverse email lookup, email blacklist and disposable-address checks, catch-all detection, and email extraction.

Mailsfinder says its multi-step process uses pattern checks, DNS queries, and real-time SMTP validation, and reports verification accuracy of up to 99.8%. Customers can upload CSV files, use a Chrome extension, export results, connect with CRMs and Salesloft, or integrate through Zapier, Make, and a REST API. Pricing includes a free daily allowance, monthly plans, and a one-time lifetime credit option, with different credit volumes and API access across plans.
