Mailchimp : Send contact to Mailchimp only if user wants to subscribe

On our Jotform, we have a question that asks "do you want to subscribe to our weekly newsletter?" How do we send only those that answer "yes" to our MailChimp account? Please note, I am not asking to set up 2 different lists as a prior user asked. We merely want only those that answer "yes" on the Jotform question to be added to our Mailchimp newsletter account. Thank you.

When you create Mailchimp integration with JotForm, you can choose to send the contact information to MailChimp. 

You can allow users to decide if they want to be added to the Opt-in list by using a Send if the user agrees, so this will work if a checkbox into the form is ticked.

This is also explained in our user guide: https://www.jotform.com/help/163-How-to-Integrate-with-MailChimp
