Best Buy: Offering Deals on Bose Electronics to a Spamtrap

Best Buy, a large U.S.-based retailer of electronic goods, just sent a bulk email to an email address that closed in 2007. The ESP is ExactTarget.

A single spamtrap hit can mean many things, and in this case there are no special facts about the spamtrap or the circumstances that point to one thing or the other. So why post this? Because one spamtrap hit is not the same as no spamtrap hits; it is a data point. And although I have a good spamtrap collection, I am not the only person who has spamtraps, let alone the only person who uses email and is spammed from time to time. If this spamtrap hit was caused, not by a typoed email address (a possibility), but a list purchase or some other inappropriate form of email address acquisition, then inevitably I will not be the only one to see spam from this sender.

If others are also seeing spam from Best Buy, I want them speak up, not necessary here (although I welcome other reports in the comments) but to Best Buy and ExactTarget. That gives Best Buy the message that spamming people that never asked for their email is not acceptable. It also gives ExactTarget (which is a quite decent ESP and does not tolerate spam or spammers on its networks) the information it needs to do something about the problem.
