With our Premium MailChimp option, you can now integrate events and forms/carts/donations with your MailChimp audiences.
Set your events to automatically add attendees to the MailChimp audience of your choice. This is set up in the Advanced tab for each event under Registration Actions.
Checkout actions will allow you to add people to your MailChimp audience when they complete a form, make a purchase through the shopping page or make a donation. You can specify an add to list checkout action for each item and/or for the entire form.
