Email supports communication between the sender and one or more recipients.

Pros

• norms and etiquette are familiar to most people
• no scheduling is necessary

Cons

• it is the participant's responsibility to organize and track course email
• difficult to judge participation since you are not likely to see private conversations

Notes
Be aware that your email may be archived on other servers or may be forwarded to unintended recipients.

Users often have multiple email accounts. Make sure that students understand which account you will send mail to.
