In the Course Administration bar, select "Participants".


If you only want to send an email to students, click "Add condition" to add another filter.

In the dropdown menu that appears, select "Roles" and then select "Student" as the type.

When the selections in the filters are done, click "Apply filters".

Click the "Select all" field or select desired students by ticking the boxes next to their names. Please note, the "Select all" checkbox will only select all users on the current page being viewed.

For larger cohorts, if you would like to email all students in the course, use the "Select all..." button at the bottom of the page. 

And then select an option from the next dropdown menu what to do with the selected users.
