Apologies if someone has already mentioned this (I don't have an opportunity right now to read all responses), but it's important to check an HTML email in web-based clients such as Hotmail, Yahoo! Mail and Gmail. This is because webmail clients tend to delete the <HEAD> section of HTML emails - and often this also therefore deletes any CSS styles.
Ergo it's important to include online inline CSS.
