Catching MailApp.sendEmail delivery failure

Question

I'm trying to catch email delivery failure in an app script. I thought surrounding MailApp.sendEmail in a try catch would work like so:

function headache(){
 Logger.log("Before Try");
  try{
    Logger.log("before sendEmail");
    MailApp.sendEmail("[e-mail]", "Ima Error", "");
    Logger.log("after sendEmail");
  }catch(err){
   Logger.log("In catch");
    MailApp.sendEmail("[e-mail]", "Ima catched Error", "");
    } 
  Logger.log("After Try");
}

but this is the output im getting:

Before Try
before sendEmail
after sendEmail
After Try

Is there a way to catch mail send failures?

Answer 1

Email sending is deferred and there is no way to catch this error.
