Craigs List Scraper & Emailer

I would like to have a software similar to this link... [login to view URL] This program should allow me to respond to posts made by users of the following web sites. [login to view URL] [login to view URL] [login to view URL] Program should allow me to extract the email addresses of ad posters and narrow down through categories and regions. After I collect, I want to send mass email to the collected emails thus their should be a feature to toggle between third party email accounts and rotate sending emails to different accounts to avoid blocking of email. Basically I want to collect email addresses from [login to view URL] [login to view URL] [login to view URL] using keywords I enter, then I want to be able to send an email to all this emails I collected like a bulk emailer.
