You can automate it a good deal with a mix of scraping and mturk, but that will result in both e-mails and phone #s, so your choice on what to do with them.

And experience w/ calls--I wouldn't say it was bad experience, it was just better with e-mail--tends to cut to the chase and replies are a better indication of interest. Everyone's selling something--even if you just want to talk to someone about their problems, you're still selling them on the proposition that it would be a more valuable use of their time talking to you than doing something else. And that doesn't make you a bad person, it just doesn't make a difference whether you're asking for money or someone's time.

But yeah, would be very interested to see your results w/ cold calling vs email, if you do two more rounds of e-mails and leave 3 vm messages on your cold calling before giving up, I'll bet you still do better with e-mail. But again, very interested to see your numbers, so very cool experiment!
