How to I format emails such as left-aligned?

When I send an email to my volunteers or students, they look left-aligned. However, when they are received they are center aligned. How do I get my emails to stay as I send them and force them to be left-aligned. 

Center-aligned is really annoying and hard to read. 

Also, I can't cc myself on emails that are sent out. I can only send one to myself as a participant. If I'm sending an email to everyone (students and volunteers), that's fine. But if I want to send it to just students and one for myself, it's not so easy. I have to click every person individually. 

Thanks!
