Essen Target Harvester is designed to extract email addresses from web sites using the HTTP protocol. It does not depend upon any additional software unlike many email harvesters that depend on Internet Explorer. Essen Target Harvester is a very fast program that supports multi-threaded (multiple connections to the web server) web page loading from web sites. It requires very few machine resources while running and is very easy to use. In order to operate, it needs a computer with a functioning connection to the Internet.
The program searches the website, given as a URL or list of URLs, at each level and each link in order to extract email addresses. It can search from a list of manually entered URLs or generate a URL list to harvest entire sites. The address extraction is extremely fast. It can connect from 1 to 15 sites at once, or you can control the number of connections from 1 to 100 with a web server. It can avoid email addresses with keywords that you provide. It can also be set to only accept URLs with keywords provided by you. It also allows you to pause while going offline for other tasks. The program can resume the harvesting process at the same place where it left off, even if your computer crashes. Essen Target Harvester can save a list of extracted addresses to a file and add more addresses to it later. It will find and delete duplicate addresses and can be set to exclude filtered domains and text such as .mil or .gov. It also displays a detailed activity window. The program is very easy to use and also contains online help. User manual available for download in Acrobat PDF and HTML formats.
