Okendo Product Review Aggregate Feed

Posting the answer here: 

You'll need to go through the steps here to add a web feed. 

Then in the email paste this code as a source, wherever you want the snippet. 

{% with productId=event.ProductID|slugify %} {% for value in feeds.product_review_aggregate %} {% if productId == value.product_id %}
<table cellpadding="0" cellspacing="0" style="border:0;">
 <tbody>
 <tr>
 <td style="padding-top:2px;padding-right:2px"><img height="14" src="https://d3hw6dc1ow8pp2.cloudfront.net/emails/review/stars/stars-{% widthratio value.rating 1 10 %}-000000.png" style="height:14px;" /></td>
 <td>
 <p style="padding-top:1px;padding-left:2px;font-size:14px;">{{ value.count }} {% if value.count > 1 %} Reviews {% endif %}{% if value.count == 1 %} Review {% endif %}</p>
 </td>
 </tr>
 </tbody>
</table>
{% endif %} {% endfor %} {% endwith %}
 

Change event.ProductID|slugify to the product Id. For example: productId="123456789" 

Just make sure to keep the quotation marks
