I\'m making a template for email in html, it works fine in apple email clients, gmail, hotmail and windows mail 2006. It does not work in outlook, it stretches out, the font
I'd suggest having a look at www.emailology.org. I've found it very useful when building emails for Outlook. As a rule for HTML emails, I build them purely in tables and with styles on the elements. It's horrible and like building bad websites years ago but unfortunatly it seems to be the best solution available.
For example, I'd change to and so on. Build it and style it like you would do normally but when you are happy enough to test it copy all the styles inline.
Have a look at Emailology though. It's a great resource.
