title: how to make html email look exactly the same as previewed just in browser?
body: <p>I'm working on a HTML email template and I noticed that the preview I got in browser is a little bit different from what I really got in my email inbox. Like sometimes you may make two tables line up with each other in browser but in the email you got, they may not line up anymore and there is some small difference.</p>
  
  <p>So I just want to know if it's possible to make the html email previewed in browser exactly the same as what you got in your inbox. I know this definitely has something to do with each individual email service provider, which has its own default css or sth like that for email, and also the browser and operating system you're using. But is it possible to make sure at least in one email service, such as gmail, that every time what you preview is exactly what you get in your inbox regardless of what browser or operating system you're using? How hard is it?</p>
