Detailed documentation
 get  
 
 Gets the user's email address, if available. If security policies do not allow access to the
user's email address, this method returns a blank string. The circumstances in which the email
address is available vary: for example, the user's email address is not available in any
context that allows a script to run without that user's authorization, like a simple on  
or on  
trigger, a custom function in Google Sheets, or a web app
deployed to "execute as me" (that is, authorized by the developer instead of the user).
However, these restrictions generally do not apply if the developer runs the script themselves
or belongs to the same Google Workspace domain as the user.
// Log the email address of the person running the script. Logger . log ( Session . getActiveUser (). getEmail ());
Return
 String 
— The user's email's address, or a blank string if security policies do not allow access
    to the user's email address.
