How can I add guest emails to my mailchimp integration?

I set up an integration with Mailchimp and the emails are being sent to the main form-filler's email perfectly. However, the emails are not being sent to the guests that the user enters. How can I add the guest emails to the Mailchimp list as well?

Are you seeking to create a second contact with the guest information? That is not possible, the Mailchimp Integration will add one contact per each submission to the MailChimp list.
