I'm promoting a high end product that is targeted specifically to webmasters email addresses currently using ppc. Ideally I would like to find a practical way to harvest their email address, as well as First name and domain they are promoting via ppc (obv. will be same as @ domain in email address for many of them) Any practical way to do this, or place to scan or buy these type of leads? I feel like there has to be some directory that should make this pretty simple with the right software. All opinions appreciated.
