The difference here is 10 cents for using greeting card engine..then there will drop off for the people who sign up for newsletter..then drop off in terms of maintaining+monitoring the newsletter and the final small conversion ratio in terms of newsletter subscriber signing up for the offer..because the $3 was per sign up..I am actually curious about math..because say there are 1 million subscribers and 1% of they sign up as user for VC funded company's offering then it is just 30k in revenue.. and 1% is not low in the given scenario (a reason most of the newsletters don't host ads is the returns are very low)..I want to learn more how can the returns were much higher in this scenario..unless the users were more like bzzagent where they are going to get something in return and actively monitoring the newsletter to sign up and get some cash incentive.. similar to what bzzagent does or subvertandprofit/usocial etc people do for gaming social media sites
