Hey there, I am just about to implement a marketing stunt for a website where I'm going to be offering free content. The catch? The user has to send the link to 10 friends in order to see the contents (otherwise sold for 198 dollars). Im going to be using Viral Inviter for this, this is where you log in to your e-mail account right from Viral Inviters interface and you select contacts and send a programmed message to your contacts about the site. What if the site was generating say.. 50,000 invites, they are not originating from my server but from the person's own e-mail address. Any problems with this? I'm not chargin anything, and they are loggin into their e-mails to send out the invitation. Any insight? Thanks
