the p doesn't wrap within td, see the demo below:

<td align="left" style="padding:0px; width:200px;">
<img src="http://placehold.it/200x200" />
</td>
<td style="padding-left:20px;max-width:100%;">
<p>dfgdfgggggggggggggggggggggdfgdfgdfsdsdfdfgdfgggggggggggggggggggggdfgdfgsdfsdsdfdfgdfgggggggggggggggggggggdfgdfgsdfsdsdf</p>
</td>
