HTML email table stretching horizontally when lots of text - html

Question

I am trying to create a responsive HTML email. The two columns should be equal height and they currently stack on mobile. Everything works properly until there is a lot of text as the Billing Information or Shipping Information. It's an unlikely case that the text will ever look like this, but I must handle all possibilities without the email breaking. How can I make my td stretch vertically instead of horizontally? I cannot use a fixed width as it will break the responsiveness of my table.
<table align="left" border="0" cellpadding="0" cellspacing="0" class="mcnTextBlock" width="100%">
<tbody class="mcnTextBlockOuter">
<tr>
<td valign="top" width="100%" class="mcnTextBlockInner" style="padding-top:9px; padding-right:18px; padding-left: 18px; padding-bottom: 15px;">
<!--[if mso]>
<table align="left" border="0" cellspacing="0" cellpadding="0" width="100%" style="width:100%;">
<tr>
<![endif]-->
<!--[if mso]>
<td valign="top" width="600" style="width:600px;">
<![endif]-->
<table align="left" bgcolor="white" border="0" cellpadding="5" cellspacing="0" style="max-width:100%; min-width:100%;" width="100%" class="mcnTextContentContainer">
<tbody>
<tr>
<td valign="top" width="50%" class=" templateColumnContainer"">

<table border="0" cellpadding="5" cellspacing="0" width="100%" style="max-width:100%; min-width:100%;" class="mcnTextContentContainer">

Using style="overflow-wrap: break-word;" on the <td> solved my problem. It is compatible across Gmail, Apple Mail, Yahoo, latest Outlook.
