To Setup the MailChimp List Dashlet:
First, you need to go to a Target List record. The Target List module can be found by default on the dropdown navigation bar.
From here, you will need to choose a Target List that is synced to a MailChimp List.
In the upper right corner, click the dropdown arrow next to "Create" and click "Edit".
This will allow you to add a new dashlet to your dashboard. Add a new row to your dashboard.
Once the new row is added, click the large plus sign.
When you do this, a list of available dashlets will appear. You want to select the dashlet called "MailChimp List Settings". If you do not see this in the list, you may want to refresh the page and follow the steps to get back to this point. There may have been an issue with your installation, contact support for more help!.
After clicking on the dashlet, click "Save".
Once all of this is setup, you'll see a quick summary of the MailChimp List that is synced with this Target List.
