You may experience an increased number of bounces from yahoo.com email addresses. We recently discovered that hard bounces from Yahoo.com were not being reported in in the Email System report section because of changes Yahoo had made to their automated bounce response message. For example, if an email blast was sent to a non-existing yahoo account, the bounce would not register in Email System.

When an email is sent to another mailserver, it returns a message to the sending mailserver that notifies us of its status as recieved or bounced. Our mailserver is set to only perceive a standard group of bounce messages. Because Yahoo changed their standard bounce message, Email System did not recognize the error and thus did not report any bounces.

We have since corrected this and Email System will now acknowledge Yahoo's new bounce message and bounces from Yahoo will be reported correctly! Because of this, you may see many bounces from Yahoo that you otherwise may have not noticed or thought were delivered in past email blasts.

We apologize for any inconvenience this may cause. Please contact us with any questions you may have.
