HTML email in Gmail - CSS style attribute removed

Question

I'm working on an HTML email and I am using MailChimp's Responsive Email Templates in combination with their CSS inliner tool. For the most part, the email looks great across the myriad of email clients, but in Gmail things are horribly misrepresented.

If I use Gmail's "Show original" option from the drop down menu next to the reply arrow, the original HTML is different from what is actually displayed in the email client. I can confirm this by inspecting the element with the developer tools. This happens on desktop and mobile; the email client is removing inline style attributes from elements.

It seems that one of the criteria for removing the style attribute is if the element also contains a class. Can anyone confirm this? Also, it appears to remove all style attributes from a table tag regardless. Can anyone confirm this as well?

What are the workarounds for this?

As someone who regularly codes emails for marketing campaigns at my job, I feel your pain. Gmail, along with many other email clients, can be a bit funky to code for. For one, it strips out any CSS that's outside the body. So putting in things like media queries and document level styles don't work. The best piece of advice I can give you is hand code your inline CSS and try to avoid anything fancy. In fact, if you can use an HTML attribute to do your styling, use that in place of any CSS. An example would be bgcolor instead of background-color.
