Linking to an External Stylesheet in Email
So what is the current status of linking to an external css file in email? I do a fair amount of production work where the client has supplied the HTML and I am looking for ways to streamline my workflow. - Thanks in advance for your feedback.
You can link to an external CSS and send the email that way but it isn't widely supported. Anything apple has full support, everything else is only partial support or none at all.
What you could do is use a CSS inliner to inline all your styles and send the outputted code. I use it for a client that sends a lot of emails. The link below is one that I use.

I did some basic testing a couple of months ago and have a list of clients that seem to support external stylesheets: https://litmus.com/community/discussions/6405-external-stylesheet-support
