A client needed to import her RSS feed into a MailChimp campaign but the image wasn’t showing up. Here is how I finally got it to work.
You first need to make sure the feed (yoursite.com/feed usually) is correctly bringing in the first image. I used a plugin called wpRichFeeds plugin removed, here is a new download link (view plugin author site) which adds the enclosure information to your feed in WordPress. This is basically plug-n-play.
Then with some creative MailChimp RSS merge tags I got it to work. This is what I used:
I hope this will save some people the aggravation of trying to get MailChimp to automatically pull in blog post images from an RSS feed.
This post also helped me get to this point, RSS email: include post thumbnail image from WordPress RSS feed
Here are the MailChimp RSS merge codes for reference.
Please comment if this helps you out! Any tweaks?
