You may be able to use Conversations to send a message to all users in a course, all users in a specific role, or all users in a group.

If your recipient list contains more than 100 users, your message will automatically be sent as individual messages to each user.

Notes:

• Messaging all users is a course permission. If you cannot send a message to all users, your institution has restricted this feature.
• Once your course has concluded, you cannot send a message to all users.
• Users display in Conversations once they have an active enrollment in the course, and users cannot join a course unless it is published.
