Verifox

Verifox is an email verifier and email finder in one account, built to protect email deliverability.

Email verification: paste an address into the free email checker or upload a CSV to the bulk email verifier. Each email gets 9 checks: syntax, DNS and MX records, a live SMTP handshake, catch-all resolution, disposable and role detection, domain age, and SPF, DKIM and DMARC. Results come back valid, risky or invalid with a confidence score, so bounces drop and lists stay clean.

Email finder and email lookup: find a verified work email from a name and company or a LinkedIn profile URL.

For developers and AI agents: a REST email verification API for real-time and bulk checks, and the Verifox email verification MCP server, which lets Claude, Cursor and other Model Context Protocol clients verify and find emails.
