If you send e-mails and/or SMS/text messages using the Standalone E-mail Robot, it's good to know if for some reason it's not running. If the Standalone E-mail Robot has not run recently (Only if E-mail Robot not running...) and no recent notifications have been sent about this event (Don't notify about this...), this generates a single notification record telling you when the last time the Standalone E-mail Robot was last seen to be in operation.
Unlike object-specific notifications VSys will re-notify you about this condition more than once, hence the Don't notify about this... setting to prevent a constant stream of duplicate notifications.
