Verifox
What it is
Verifox is an email verification and discovery service for teams that send cold outreach or manage large contact lists. Each address runs through nine checks in parallel, including syntax, DNS and MX records, a live SMTP handshake, disposable and role account detection, catch-all handling with an AI confidence score, domain age and SPF, DKIM and DMARC authentication. Results come back as valid, risky or invalid with a per-check breakdown. You can paste single addresses, upload CSV files, use the real-time and bulk API, embed a form validation widget or connect AI agents through an MCP server. Email finder tools look up addresses from a name and domain or a LinkedIn profile. A free allowance of credits is available at signup.

Editor's notes
More context from AI BirdView
Verifox focuses on a problem many outreach teams quietly struggle with: addresses on catch-all domains that basic verifiers simply label unknown. Its approach is to run a wider set of checks on every address and add an AI confidence pass for those uncertain cases, so you get a more usable verdict instead of a shrug. The site is also unusually candid about the limits of email verification.
- Nine checks run on each address, from syntax and MX records to a live SMTP handshake
- Catch-all addresses receive a confidence score rather than a blanket unknown label
- Domain age and SPF, DKIM and DMARC checks add context about sender quality
- Access options include a web checker, bulk CSV, a REST API, a form widget and an MCP server for AI agents
- Email finder tools cover name plus domain lookups, LinkedIn profiles and whole domains
It is best for sales teams, agencies and marketers who send cold email and want to protect their sender reputation before a campaign goes out. A practical tip: sign up with a work email to claim the larger free allowance the site advertises, then run a sample of your list first to see how many addresses land in the risky bucket before buying credits.
