Adding css in html that will be sent to an email

I have created a method that will send an email with information to customers. However, the email looks awful cus there is no style to it. I can’t apply the style to the email for some reason. I have tried to google it, and there is a lot on how to solve this in code behind, but that’s not my issue. I must place the css code in the Html body, since it must be displayed for the client when he opens the email.

Why can’t I share Session state between 2 web apps with StateServer? What am I missing?

I’m having trouble getting 2 identical ASP.NET MVC applications to share the same Session using a Session StateServer. The reason I’m trying to do this is we will eventually be deploying this app across 3 web servers that need to share the same state. We need to use StateServer because we are trying to minimise use of the db for non data-related storage.
