The facilities provided by SFI to Team Mail every week to CSAs and PSAs by e mailing is a fool proof way to ensure that the messages are received. Apart from this the weekly stream messages too should reach them if they use the computer.
However if they do not login daily and do not read e mail messages there is no other way of making sure that messages will be received. Further, if they do not respond it is obvious that they are inactive and nothing further could be done.
