This plugin makes it easy to display the featured images of your posts in mailchimp RSS newsletters.
Once activated this plugin will add the following to your sites default rss feed:
To the rss name space declarations:
<pre><code> xmlns:media="http://search.yahoo.com/mrss/"
</code></pre>
To each individual item (if it has a featured image):
<pre><code><media:content url="[url]" type="[mimetype]" medium="image" width="100%" height="auto">
 <media:description type="plain"><![CDATA[title]]></media:description>
</media:content>
</code></pre>
The featured images are not inserted directly into the content of your posts, so you have full control over where and how to present them. 
If you send out newsletters using a Mailchimp RSS based Campaign, simply place the *|RSSITEM:IMAGE|* merge-tag in your mail template where you want the featured image inserted.

<h3>Important Notes</h3>
This plugin supports our most powerful API 3.0 features, and is intended for users who have not yet integrated their WooCommerce stores with Mailchimp. 
You can run this new integration at the same time as your current WooCommerce integration for Mailchimp. However, data from the older integration will display separately in subscriber profiles, and can’t be used with e-commerce features that require API 3.0. 
WordPress.com compatibility is limited to Business tier users only.

Mailchimp for WooCommerce

Very basic plugin. If your needs are little, it works fine. But if you want to segment based on orders your customers made, you can only segment on basic things like product purchased, purchase date, store ordered from, etc. You can nog segment on product variations or SKUs.

No support for product variations


Good for me, and I translated in Japanese.


Good


This is the second time this plugin has collapsed my server. The first time was during a sync, and now, after archiving a large contact list in Mailchimp, the plugin started receiving an overwhelming number of requests, maxing out my server's CPU at 100%. This made my website nearly unusable and caused significant downtime.



Take care with this this plugin, it could cause serious performance problems.


Severe Performance Issues – Has collapsed my server twice
