If a person unsubscribes from an audience in Mailchimp, their membership record will be instantly updated. In Salesforce, this will be automatically reflected on the Salesforce contact or lead record via our membership component. The component is updated every time the primary sync runs, typically every hour. You can also click the refresh icon on the top right of the component.
It is important to note that even if the membership audience's status has not been updated in Salesforce, Mailchimp will be the source of truth, i.e., an active status in Salesforce will not override an unsubscribed status, and the audience member won't be made active again.
