Hi, I've a e-mail database to use with Facebook. I say this because I tested mails and from 5000 invites I get 200/300 Friends (5% conversion I think is good). Now I want to ask to you if this can be a service and where to sell it. And how much can coast this? Invites can't be used for groups because I need to insert them one a time, but for Friends requests and Page likes it's good. All Mails are targheted in a niche. If you've other suggestions or other methods where use this mails you're welcome, I want to monetize this list (1500/2000 new mails a day).
