What’s the Conversion Rate for Spam Email?

“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:

1. Spam operating costs have dropped by an order of magnitude in five years.


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.

    Interesting that they hijacked part of a network of hacked home computers. If this is so easy, why not fight spam with vigilantes fighting to take control of the networks. Great fun!
