Hello Ryan ,
Moodle do not send any password in mail to any users . If you set to "Forced password change" option during upload users, then also it will not send email but when a user login moodle with their default credentials he will get a option to change password automatically after logged in. It is useful when you set the same password for everybody and for security purpose you want students to personalize their own password.
