Send out email to all students in the course where the recipient list is not shown to recipients.
You can use UB Learns to send email to course participants. You will not receive email within UB Learns; you must use an email program to read email sent from UB Learns.
Recipients of each email will not see the email addresses of other recipients.
Instructors have the option to disable email features. Go to Control Panel > Customization > Tool Availability > Email.
