A email extractor

A email extractor known as e-spider. It works much the same way that Google uses an automated spider to crawl the Internet looking for sites. But instead of looking for sites, is an e-mail spider web looking for email addresses. Each time it finds one, add it to the list. An e-extractor can spend days or weeks searching the web to build up a database of thousands of email addresses. After this, the marketer sending an email to all email addresses asking people to buy his product. He normally does not get a high percentage of sales, because most people immediately delete the e-mail that they suspect are spam. However, he can get some sales, otherwise the practice would likely disappear. In addition, he is often out e-mails that are more targeted.
