How do Email Spyders filters work?
Answering that question can not be summed up briefly. Email Spyder offers a series of 6 major filtering options & many other alternate filters allowing you to create infinite combinations of “includes and excludes”. These includes & excludes work with the Spyder analyzing the pages it visits, the URL’s, the depth of the pages it’s spidering, the pages META tags, content, descriptions, and even the email addresses itself & compares it to keywords you tell it to filter.
