Identify yourself fully.
Please include full identification of who you are when you generate or reply to an email to your instructor. This should include your full name (first and last) as well as the course you are enrolled in. I teach 7 sections and multiple sections of the class you are enrolled in, so if you want me to check on something for you, I have to know who you are and what course you are in to do that. In the subject box of every email, please type your full name, course and section number (e.g. Sue Jones. Eng.1301.8420).
Write with civility and respect.
When asking questions or making comments, do so in a respectful manner. If you are frustrated or irritated when you write the email, wait a minute to reread it asking yourself if the tone is appropriate for a student-teacher interchange before clicking Send. If you're really upset, write the email in Word and copy and paste.
Practice patience
Most instructors will answer Emails within 24 hours of receipt Monday-Friday and often sooner. Post your email turn around time. Usually I read email on the weekends, but some weekends, I will not be available.
Copy yourself.
Send a copy of each email you write to yourself so you can be sure the email went through, and so you can resend it if there is any problem.
Brevity
Keep emails brief and to the point.
Do not forward unsolicited material.
Do not forward material that you send to your friends to your classmates or professor. (Note: If you send emails to everyone in your address book, they will automatically go to your professor and any student in the class who has emailed you.)
