“After 26 days, and almost 350 million e-mail messages, only 28 sales resulted,” wrote the researchers. The response rate for this campaign was less than 0.00001%. (Via BBC News)
That’s one sale for every 12.5m e-mails sent. A 2003 article in The Register put spam’s breakeven point at one in a milion emails, suggesting that either:

2. Berkeley/UCSD researchers are RUBBISH at pushing penis pills.
Either way, I recommend Conversion Rate Experts’ new report on how to improve conversion rate.
