Inline css is probably the safest way around, but if your target audience is all relatively modern computers, your best to stick with CSS in the <head> of the email.
This reduces the size of the email and makes it less likely to be detected as spam (the more html you have in your content over the standard text the more spammy an email appears.)
I have found this also helps a lot if you are using an online editor to keep the consitency of the content by setting one text size and font at the top.
This is supported by most of the major email programs (gmail, outlook, thunderbird, apple mail, haven’t tested in any others as of yet)
