I'm curious to know if anyone has tried or succeeded in using transparency for emails. I've used it once on a background color so that the background image being used could be seen through the color band, however I could only get it to work minimally and it also made all the text within that section transparent as well. I've only tried this once and with that small success haven't ventured further. I'm interested in knowing if anyone has done something like this and what their outcome was.

Please let me know what you've come across and if you have any coding tips for something like this please let me know.
