Hunter.io
Finds and verifies professional email addresses associated with a domain.
Hunter.io is a freemium tool that identifies and verifies professional email addresses associated with specific domains. It is commonly used by researchers and investigators to map out organizational contact structures and validate potential points of communication. The service helps users confirm the existence of email patterns within a company's digital footprint.
Dual-use tool. This tool can be used for research and investigation, and also to find, track or identify people without their consent. Listing it here is not an endorsement of either use.
Privacy note. Hunter crawls public web pages for names, professional email addresses, job titles and social-profile URLs, and can generate a professional email address from a name and employer when none is published, so a work address of yours may be findable through your employer's domain. Hunter publishes a claim page (hunter.io/claim) that says claiming an email address removes the information associated with it.
