We run a referral program at 8centsms.com We have a very small user base at the moment (about 100 regulars) and about 10 are really into the product and give us great feedback. Of those 10 there is 1 that has really given the referral program a go with gusto. He crafted up an email, sent it to just about everyone he knows - seriously like 100 emails, with a very in depth explanation of why he liked the service. Zero response. Why? Because the format of the email is so spammy. The email subject still says "You have been invited to ... " etc. Our goal now is to try changing the program so that instead of sending out referral emails from our interface, each person gets a unique referral signup URL that they can send to their friends in whatever format they like.
