Announcement Forum
To post an announcement-style communication to your students, you can use the Announcements Forum that is located at the top of your course site by default. Any posts you make in this forum will be a one-sided communication. Students will not be able to post replies to your post.
Open Forum
You have the option to create an open forum(s) in your course for students to post questions or comments about course content or logistics. This can potentially decrease the amount of questions you will receive directly. It would also give students an opportunity to interact with one another.

Feel free to invite students to host Zoom sessions with classmates, similar to an in-person study group.
Quickmail
To send a mass email communication to all of your students at once, you can use the Quickmail block on your course site, which is located on the course site homepage by default. To craft a new message, select "Compose Course Message" on the Quickmail block.
Within the Compose Course Message page, craft your email like you would in any email application. To select the recipients of the email, click on "Who should receive this message," and select the recipients from the dropdown menu. Generally, you will select "Student (Role)."
After composing your message, select "Send Message" at the bottom of the page.
