I constantly receive emails on my sites from other advertising companies trying to get to to become a publisher with them. I only use Google and CPMStar, and in both cases I contacted them to join, and I have always been pleased with them. Am I right to say that only the new and desperate ad companies are the ones who contact people to become a publisher? Every time I look up the company that is emailing me I either cant find anything because they are brand new, or I find a post on here where people say they are no good. I think I am going to simply delete those emails from now on and no longer research the companies.
So you think they aren't even looking at my sites and just emailing everyone? A few of them do mention content in the subject line that involves my sites, and if I write them back they respond, but then they keep responding daily even when I stop replying.
