An issue has been discovered in the 5.3.6 release that results in CSS styling not being applied to emails when sent to end users. It is important to note that the email does still work, and all information contained within it will be displayed, but the lack of CSS formatting can cause it to display in a less than ideal way.
As a result we are issuing a hot-fix patch to address it.
