Sending email when a job starts/finishes is not working

  • Check that the option is correctly set in your batch script. For example, to get email when the job starts, it should read #SBATCH --mail-type=BEGIN.
  • Multiple arguments are separated by a comma, e.g. #SBATCH --mail-type=BEGIN,END.
  • The email is by default sent to the email address linked to your CSC account.
  • If you are using the #SBATCH --mail-user=<your email address> option to override the default email address, ensure that the email set is valid.
