During the account setup, we ask you if you want to receive email notifications. You can choose which type of email notifications you would like to receive. To change these settings, hit the Notifications icon in the header bar.

In Notifications, you go to Settings by clicking on the "gear icon".

The settings let you toggle the notifications you want to receive. You can switch them all on/off at once, or make your own combination of notifications that are important to you.
