About Brightspace Email
Brightspace email is an internal (closed) system which means that you must log in to Brightspace to read AND reply to messages, and you can only send email to other Brightspace users (email cannot be sent out to an external address).
Students and faculty can set their Brightspace email to forward copies to an external email account such as mySFA, Gmail, Yahoo, and others. HOWEVER, be aware that . . .
You cannot reply to a forwarded message from an external account. An example would be that Amy has her Brightspace email forwarded to her Gmail account. She reads her messages from her Gmail account, and if she wishes to reply, she MUST enter Brightspace to reply to the message. If she attempts to reply to a Brightspace message from inside her Gmail account, the message will fail to send.
A big advantage to Brightspace email is that you may filter by class. This is a huge time-saver. Another advantage is that you won't receive SPAM messages inside Brightspace.
