I liked seeing the exact bounce message before this latest "upgrade" because I could sometimes glean more information about the bounce and whether to remove the email from the list or try again.
On the bounce list, when I click on one Contact, it only tells me that she bounced the last couple emails, but does not say WHY those previous month emails bounced. The report shows why for the current month, but not why for the past months, as it used to do in the past.
