Our MailChimp integration requires the user map which campaigns and lists you would like to pull data from. To do this, go to:
Dashboard > toggle left-side menu > Integrations > MailChimp > Custom Mapping
Then click the green plus sign (+) next to "Campaigns" and select the campaigns you would like to view data from.
You will now be able to view data from these campaigns by selecting them as a single metric in your Dashboards view.
