Under Reports from the left-hand navigation menu, you can easily set up your reports to send automatically. There are two steps:

After setting up the details of the reports you want to run, you can save your reports' settings to access them faster next time. Simply click Add to my favourites at the bottom of the page.

You can then access these reports by clicking on My favourites in the top-right corner.
