You can use the Trigger Event action that comes with the MailChimp add-on to fire events on the MailChimp platform. To make these events more powerful, it’s possible to pass parameters from your WunderAutmation workflow over to MailChimp and use those parameters in an outgoing email.
A popular use case for this is to use WunderAutomation to generate a WooCommerce coupon and then use MailChimp to send that coupon to a subscriber.
