Once you've logged into your Webmail dashboard, you will see the My Today Page. 

The My Today Page gives you an overview of your entire account. 

Calendar - lists upcoming events on your calendar. Note that your webmail calendar is separate from your Website.com Calendar application and events you have added into your Calendar app will not be sync'd onto your webmail calendar.

Latest RSS Items - list recent updates to RSS feeds you are subscribed to.

Inbox - lists how many unread messages you have.

Disk Space Limits - lists how much space is available and how much space is being used in your account. Click the Clear Junk E-Mail Folder link to remove all items from your Junk e-mail box.

Tasks - lists unfinished tasks.

The My Today page is the default page to load when logging into your account. If you would rather go straight to your Inbox you can change it by going to Settings|My Settings|WebMail and changing the Initial Page on Login setting.
