I've connected Mailchimp and Quickbooks. When my customers/members get an email from us, they can manage their preferences (like updating their email address) and that info is all stored in Mailchimp. Does the Mailchimp / QBO sync mean help get Mailchimp information into QBO?  Or only QBO info over to Mailchimp?

I want the data to go from Mailchimp and update QBO. How can I do that?
