Not sure if this is possible..
My MailChimp account has a 'Connected Sites' section where you can connect your website.
As Wix isn't one of the standard connections they offer, code is provided to add to your website.
Is there an easy way to copy/paste this MailChimp provided code when I have no coding knowledge?
