I was trying to contact the students of the Spring quarter course through Canvas email now.
However, although I sent some messages via Canvas, they haven't received my messages (I heard this from some students).
And today, I tried to send a message to myself for a test, but I haven't received the message yet.
I wonder if after the quarter is done, I can no longer send messages to students on Canvas?
I would really appreciate if you help me to deal with this problem! Thank you!
