AOL uses the following default CSS:
body {font-family:Arial,sans-serif;font-size:10pt;}
th {font-size:13pt;}
td {color: black;}
You just need to overwrite this in your embedded CSS.
To achieve the same effect in Gmail, you can set the font in your body tag (you need to use inline CSS for the TH and TD, sorry!). Here is an example:
<body style=†font-family:Arial,sans-serif; font-size:10pt â€>
