For kind of standards I always think that you can't do whatever you want with emails, like adding a youtube video, or background video and so, that's not how it works and yet clients still want their email to look 'amazing' with lots of things that are not allowed and eventually you have to make just a image and that's it, even though you prevent the client that it will probably be rejected or treated as spam and is not going to display correctly in mobile devices but they don't care at all.
Anyway... take a look at this framework is basically a responsive framework for emails. Haven't tested it yet but seems to be a very good one.
