An email extractor, simply put, is kind of software program that can find and extract, or harvest, any email address form guest books, web sites, search engines and other various forms of information. Most people think that email extractors are a spamming tool. And while most major spammers do use these forms of technology to do their grunt work, extractor programs are legitimately used for other purposes as well.
There are many different types of these programs, and they work in different ways. There are also many reasons to use these types of programs, most having to do with increasing office productivity, sales and marketing strategies.
For example, if there is a guest book on a website, the owner of that site will want the email addresses of the people who have signed it. This could be so the web site can send those people advertising of new products and services, or just for send out general updates about the content on the site. The web site owner would then use this software to easily gather the email addresses to send this information to.
Some programs are better than others being as they are faster and more accurate in their searches and return of information. Many programs, while they may return thousands of address, most of these address turn out to be duplicates or invalid in other ways, such as old or expired and no longer in use.
The best programs available should be fast enough to gather hundreds, if not thousands, of email addresses within minutes, all of them being valid. These programs should also be fully automated so that the criteria are entered once and the program runs by itself. The best fully featured, easy to use programs should also use less CPU resources, allowing for other pertinent programs to be run at the same time to maximize productivity
Keyword based programs have been developed to grab email address form various search engines. They work by the user entering a keyword into the search field and the program then searches all of the top ranked pages in the search engines and returns the un-duplicated addresses. A domain search works in the same way as the keyword search.
The only difference is that you enter a web address into the search and the program will gather all of the email addresses on the page, or on the complete web site.
Used correctly, these programs have proven their worth with ever increasing productivity and sales within the business using it. Most businesses see immediate results after running these programs and are satisfied with the job well done. Costs go down, as most of these programs are free, sales and productivity get a major boost, and business owners are happy with the results making these programs one of the best additions to the software world.
