I receive a huge variety of email HTML code from various developers. Some are elegantly hand-coded with only the absolutely necessary inlined CSS. Others are clearly the output from CSS inlining tools. They have a lot of redundant tags and the code is weighty.

Now that Gmail accepts embedded CSS, is it time to stop over-zealous inlining or at least refine the tool to be more selective of CSS that absolutely needs to be inlined? Are there major email clients that still don't accept embedded CSS?
