That should be impossible with a correctly installed version of the module. It checks the format of the e-mail address so only valid e-mail addresses can be stored.

The only situation in which this could possibly happen is if the customer subscribed to the notification has deleted their account, in which case after the notification is sent out the e-mail to them should fail and the record be deleted.

All the best..
