Your email is something that you may use everyday, or may never use. From your email get important emails like the morning announcements, or you can send emails to teachers for missing grades or absences. Your email is an important tool that you may not always use, even if  you can make it more useful to you (and prettier). First off, enter your email. Then, you click the giant gear in the top left corner (near the question mark). It should say Quick Settings, underneath it click See all settings. The most useful thing for me is General. But go on and explore more of it to see which ones are useful to you. The General level has the most important things like Signatures or default text styles.
