You can set the default frequency that the statistics emails are sent out as well as the email address you would like the emails to be sent. To edit this, go to your Listing Dashboard and click on the "Settings" cogwheel: 

Then click on the "Notification" tab on the right. 

Set the stats reports to send out weekly, monthly or never.  You can add multiple email addresses by placing a comma between each address.
