Hi Kristin,
Thanks for using our WordPress theme – we’re happy to help with your MailChimp code.
There are 2 plugins we recommend looking into – Header Footer Code Manager and the official MailChimp plugin MC4WP. Either of these plugins will add the code to the correct location. The first one can be used for any type of tracking code while the second is specific to MailChimp.
Hope this helps! Please let us know if you have any other questions.
Thanks,
Nicole
