HTML email builds for Matrix Group

I've been busy this month building a variety of email templates for the Matrix Group and all their divisions from the designs they've had done. The templates have to suit their HTML email newsletter system and be easy for their team to update quickly - in some cases everyday. I must admit, I don't love their choice of newsletter system and it has thrown up some issues, with the manual contradicting itself. But maybe I'm just biased towards our 18a mail! I've since had a sales call from the mail system, and I told them I'd been using their system for a client recently... but I didn't go into a bug fixing list!
