Hello,
E-mail notifications on events reported to Watchdog were added, I believe, in version 1.2.2. You can access it through user settings and enable for each user individually (or change the default for all users through admin settings).
As for the messenger alerts - we have plans to improve these alerts, but I'm afraid this won't happen in the nearby future due to other much more important features we want to add to EPESI. But your feedback will definitely be taken into account and we will be trying to make it happen sooner rather than later.
Kind regards,
Arek
