After a frustrating and fruitless search for a simple and free solution to basic WooCommerce integration with MailChimp, I decided to sit down and write a little plugin to do just that. There are a couple of paid solutions, but, in my opinion, most are overpriced for providing such vanilla functionality. Also, it seems this functionality was previously bundled with WooCommerce and WooThemes has since removed it and made it a paid “extension.”

So, without further ado, here is my new WooCommerce MailChimp plugin for WordPress:

WooCommerce MailChimp provides simple MailChimp integration for WooCommerce.

Easily add customers to a designated MailChimp list and, optionally, MailChimp interest groups upon order creation or order completion.

Double opt-in option for anti-spam compliance.

The plugin is now on the WordPress Plugin Repository and you can get it by clicking on the following link:

Download WooCommerce MailChimp 1.0

Get the Source on GitHub


WooCommerce Event Selection

  • Subscribe customers to MailChimp after order creation
  • Subscribe customers to MailChimp after order completion

Works with MailChimp Interest Groups

  • Set one or more interest groups to add users to based on the selected MailChimp list.


  • All features should work for each blog in multisite installations but this has not yet been tested.


Feedback is welcome!

  1. Upload or extract the woocommerce-mailchimp folder to your site’s /wp-content/plugins/ directory. You can also use the Add new option found in the Plugins menu in WordPress.
  2. Enable the plugin from the Plugins menu in WordPress.


  1. Go to WooCommerce > Settings > Integration > MailChimp
  2. First, enable the plugin and set your MailChimp API Key and hit save.
  3. Select whether you want customers subscribed to your MailChimp list after order creation or order completion (there’s a difference in WooCommerce).
  4. Next, select your MailChimp list and set any interest group settings (optional) and hit save.
  5. That’s it, now customers who purchase products from your WooCommerce store will automatically be subscribed to the selected list (and optional interest groups) in MailChimp!

    Hi Adam, by testing my website I noticed an error send by MAilchimp:

    (270) “3″ is not a valid Interest Group for the list: Bewust Vrij Nieuwsbrief

    I haven’t used “3″ in my settings and whatever I trie this error stays.

    Any suggestions?
    Thanks Jerome

      My apologies for this issue. I just published version 1.3.1 of the plugin which fixes this bug introduced in version 1.3. It was a simply transposition of parameters on an apply_filters call. I hadn’t caught it because I was intercepting the bug with an add_filter call I was using to test it and that was hiding the problem on my test site. I have corrected this and tested it with and without the add_filter hook. It now behaves just as it did in 1.2.6. Please update and let me know if you have any issues.

    Hi Adam,

    Is there a way to reposition the mailchimp tick box on the Billing page of a site? My client wants the tick box to appear underneath the Shipping Address form on his WooCommerce site. Currently its default location is under the billing form.

    Any help with be very much appreciated.

    Hi Adam

    Thanks for putting the effort into this plugin. I’ve had this installed for the past 2 weeks during which tickets have gone on sale for a festival I’m organising. We’ve had more than 150 orders for multiple tickets, but as far as I can tell no one has yet signed up using this form.

    Is there an easy way to check signups? And how can I be sure that people are being linked to the correct mailchimp fields.

    Any help much obliged.

    Thank you!

      Can you tell me what your settings are for the plugin? As long as those are set correctly then orders should get sent to MailChimp depending on your settings and they should be showing up in MailChimp.
