Inline CSS, media queries & email clients dropping them

At 3:05, Fabio claims that with !important declarations, inline CSS from the email will be overwritten.

A couple videos ago, he was very clear that (certain) email clients cut out the <body> &<style> tags. He even gave tools to automate the inline CSS writing.

So now I'm confused. What really happens with these tags and how do I know which client reacts differently from another? How can I have some certainty while writing, before having to test them all out?

Thanks for answering!
