How can I send email to the students enrolled in my course from Canvas?
Canvas offers a feature called Conversations which allows instructors to send email messages to members of their Canvas course site. Messages can be sent directly to individuals, or sent as a mass email to the entire course roster. Instructors can also set whether or not students will be able to see all recipients or replies to the message.
For information on using the various features of Canvas Conversations, refer to the Canvas Instructor Guide.
