Email Extractor is a tool designed to help Internet entrepreneurs, marketers, sales professionals, etc. gather email addresses rapidly and in bulk. It would also locate those extremely difficult to find addresses that cannot be found anywhere on a site. This spider program works by crawling the World Wide Web to gather addresses based on user-outlined criteria. For example, if an individual is managing an email marketing drive aiming at birdwatchers, the user would easily look for email addresses that belong to people who have the same or similar interests. Email Extractor can also be used for extracting emails from local computer files or by domain name.
