Chase Bank: Including Customer Information in Marketing Email Sent to Spamtraps

Months after I first blogged about Chase Bank sending marketing emails to an email address that had been closed for many years via Acxiom Digital, and after I added a comment to that blog indicating that Chase was sending marketing emails to a different email address via Epsilon Interactive (Bigfoot Interactive), this second email address is *still* receiving the same bulk emails. Worse, they STILL contain the customer’s name and the last four digits of the customer’s credit card number, although the customer has not owned this email address for years!

Both Acxiom Digital and Epsilon were warned about this a while ago. Acxiom Digital contacted me about the issue, and appears to have dealt with it; at least, no more emails to that email address have been sent. Epsilon did not contact me, and also does not appear to have changed anything despite knowing (or at least having been notified) that at least one email address on their list for Chase was a spamtrap.

This email is spam, of course; sending email to a years-dead email address that rejected all email for over twelve consecutive months is an indication of a poorly managed bulk email list. However, the real issue with it is not the spam. It is that customer information is being leaked to unknown individuals because Chase either did not check to see that email addresses that it has actually belong to its customers, or for an extended period did not pay attention to which emails were rejected, showing that the email address was no longer valid. I was once a Chase customer. I am VERY glad that I am no longer a Chase customer. :/
