What is the Mailtool tool?
The Email tool allows user to send an email message to site participants by role, section, or group, and also provides a field for specifying non-site participant email addresses.
The Email tool works using the sender's external email address, which is specified in the user's account details. Typically, this email address is the user's institutional email.
Note: The Email tool can work in conjunction with the Email Archive tool to post email messages to the course archive.
