As Orientation notes, Hunter can retrieve names, titles, and emails that are “already online on other web pages.” Sales and PR teams often use it to collect contact info for potential leads or press contacts quickly. Instead of guessing or paying for lists, Hunter’s extension delivers verifiable emails with their source.
