First week and Email Etiquette

When I enrolled in IS 101 I didn't know what to expect and to be honest I still kind of don't. I understand the material but I didn't realize it would be some stuff I already know and on that topic, 1.3.10 video taught me to to be more professional and neater with my emails and what else I can do in my email . Before I would write what I wanted to say and that would be the end of that but this Video taught me more things I can do within that email then just only sending a message.
