An e-mail extractor is a program designed specifically for extracting email addresses from many different sources both on the Internet and offline. Traditionally, you might browse from page to page, copy and paste every email to a file manually.
At the mention of the term email extractor, many people already have it at the back of their mind that it is something like spam tools or something designed for the sending of unsolicited emails in email marketing and consequently, it is not legal to use it.
