What is the boards thoughts on monetizing large groups (500k+) of generic subscribers? I've got a group method that could easily clear 500k members (with about 2m being a very real possibility.) However with generic targeting, IMO it might be hard to monetize. I was thinking of getting everyone to opt into a email list, that way I could have more data on them , however mailing them would be extremely hard as I don't know how to process 500k optins then autoresponse emails + approximately a few mails per week to each subscriber. Any helps or thoughts would be appreciated.
