Summary:

Content (please ensure you mask any confidential information):

Hello,
the client asks to provide an informative notification that informs the candidate of his entry, the notification must reach different users in different offices, for example human resources, the administrative management part, his future manager etc.. Do you know if it is feasible and how?
Consider that the notification must arrive in the pre-boarding phase, therefore before entering the company on the first day.

Thank you very much,

Selene
