Unfortunately, UNA seems to strips off a lot of styling that was created elsewhere and then part of it get rejected by most of the emails, so a lot of style is lost when reaches the email and Newsletter doesn't look as nice. The tools embeded in the new mail mail is rather cumbersome and would rather create the html somewhere else and paste here and send it "untouched by UNA" to the emails (which are very picky on any style or other adjustments).
