Hey Sanford,
So I should replace my button template with something like this in order to track those who click it from outlook?
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td style="text-align: center;">
<div><!--[if mso]>
<a:roundrect
xmlns:a="urn:schemas-microsoft-com:vml"
xmlns:w="urn:schemas-microsoft-com:office:word"
href="#"
style="height:43px; v-text-anchor:middle; width:200px;"
arcsize="8%"
strokecolor="#4C4C93"
fill="t">
<a:fill type="solid" color="#4C4C93" />
<w:anchorlock/>
<center style="color:#ffffff;
font-family:sans-serif;
font-size:13px;
font-weight:bold;">Read More</center>
</a:roundrect>
<![endif]--><a href="#" style="background-color: #4c4c93; border: 1px solid #4C4C93; border-radius: 4px; color: #ffffff; display: inline-block; font-family: sans-serif; font-size: 13px; font-weight: bold; line-height: 43px; text-align: center; text-decoration: none; width: 200px; -webkit-text-size-adjust: none; mso-hide: all;">Read More</a></div>
</td>
</tr>
</tbody>
</table>
