To view the stats of your site, go to My Profile > My Account.
You can still access your profile from your admin dashboard.
On the left-hand side menu, go to Stats.
This page will give you 'Statistics' on your account, such as how many live sessions you have run and how many you have left. It will also give you information on how much mail you have sent out and whether your sender reputation is good or bad.
Additionally, it will provide you with information on your next credit resets, last credit resets, and your current email credits.
Please note that all of this information updates and refreshes every month from the start of your membership.
