Sure - you can create an automatic response to do this:
Create a new response with event group = ePO Notification Events and event type = Server.
Set the filter to Event Description equals Master Repository Update Succeeded. (or failed, if you want to be notified for failures.)
Set the aggregation and throttling according to preference
Set the action to send a mail.
I guess you could make a server response filtering on event id 16002 (Master Repository update succeeded).
You can then have the action for that response to be 'send email'
