Your html is really a mess, you have halfway done tables and a lot of incomplete stuff..
Changing:
Code:
<table cellpadding="2" cellspacing="0" border="0" width="98%" align="center">
<tr>
<center>
<table width="" border="0" cellspacing="1" cellpadding="0">
<font size=5 face=verdana color=white><b>test</b></font></table>
<table width="96%" border="0" cellspacing="1" cellpadding="0" bgcolor="393F4D">
<tr>
<td>
to>
Code:
<table cellpadding="2" cellspacing="0" border="0" width="98%" align="center">
<tr>
<td align="center">
<font size=5 face=verdana color=white><b>test</b></font><br />
<table width="96%" border="0" cellspacing="1" cellpadding="0" bgcolor="393F4D">
<tr>
<td align="center">
should do what you want, but you might want to look at that code further.. or run it through a validator..
