The security breach at Epsilon is creating headlines, but it is still not clear what the scope of the breach has been.  Have all Epsilon’s customers been affected?  For each of those customers, did the hacker get access to all the email addresses or just some?  I am sure we will be finding out soon, but in the meantime, it is clear that companies like HSN and New York and Co. are notifying ALL of their customers.

Based on the reach information provided by our email panel, we are seeing that warning notifications are going out “en masse” to the entire customer base of major retailers.  The below is an example form HSN which was sent to an estimated 10 million people on April 2nd and 3rd.
