Where do you get your mailer list?

[Michael Randle]

I am going to preference this question by saying I know it eventually comes down to the criteria of the list and effectiveness of the marketing. But I want to know what are good sites to compile a list, or what sites have the most depth of baseline information that I can filter out from there.

So with that said, what mailing list source are people using to get quality leads?

I know listsource.com is a popular one, is there any alternatives out there people tend to use and have success with?
