I've been creating HTML emails for years now avoiding CSS, DIV tags and paragraph tags (<p>) like the plague and primarily using inline styles and tables to control the layouts for multiple email platforms including mobile. I have clients asking about Responsive Email Design which seems to be using CSS. Would like to hear some thoughts on this and what software people using to create these if they are being used successfully. Just an FYI, I use Dream Weaver to build out my emails using Inline styles for everything… Thanks
