Most profs have overflowing email inboxes, making it hard to keep track of student emails.  Two ways that I've heard of dealing with this effectively is to (a) create a class specific email address and (b) have students use the messaging system within the LMS.

While messaging will work by default, you may wish to turn off the email messaging option so that you only deal with the messages while actively on eClass.

Start by "edit preferences" from your Dashboard (main, non-course page)

Edit preferences from the Dashboard.

Then Message preferences

Message preferences

turn off the email option

There is also an option for making messages "contacts only".  This may be a good idea for students who don't want to receive messages from other students.
