How can I change the subject line and/ the "from" line in the invitation email sent by Canvas? I noticed that although people are expecting the invitation email they are not accepting the link. I sent it to myself and realized that it seems like junk mail because I don't recognize the name or subject affiliated with the email. I can provide those details in my original email to the people so they know what to look for, but would like to make any other changes on the automated email if possible. Please advise.
