EUE Mail is clean, professional newsletter solution. It comes with 6 backgrounds and 4 colours, there are 24 html pages with different colour combinations..
PSD file is “sliced & named”. Just export.
You can customize it very easy by following the help documentation and HTML code comments. I used inline CSS .
All fonts are free and there are download links.
I tested on Apple Mail, Thunderbird, Gmail, Microsoft Outlook 2003-2007, Yahoo Mail, Hotmail and MailChimp.
