@LouisaKumah ...
What do you mean by "junk mail"? There is no "junk" or "spam" folder in the Canvas Inbox. And, to be honest, I've not heard of Canvas users receiving junk messages in their Inbox...as communication should be among you and your classmates/instructor(s). These kinds of folders are typically found in your normal e-mail account and not within the Canvas Inbox.
Hope this helps a bit.
