Nither suspend nor enable error email
The cp_id: xxx for which you are receiving the mails from cron are not exist into your MB(seems to be deleted) but this cp_id i.e xxx is still remain into your MB database and hence you are receiving emails from cron.
Login to your phpMyAdmin and delete the logs which you want from the suspend_log file.
you will have to edit your database and run the following command on your ModernBill database:
DELETE FROM suspend_log WHERE suspend_id = xyz
