@Jesse Deildale all those tools work, however, you ABSOLUTELY need to clean the list before emailing especially with the latest Google & Yahoo Email Slap. You do NOT want to be mailing vacated email boxes because Google has set up Honey pots in them. I do not know what these guys are using to get their lists but I am a Big Fan of D7 because I get so much more usable info then just the email addys. Like I can see whether or not they are using a WP site or not. I get most of their social media accounts so I could also contact them there as well.
