We just did something similar because our daily reports are sometimes not making it, but you can build a pretty simple workflow that runs on a schedule.  It just needs to search the repository for whatever you're looking for, in our case it's just a quantity of reports, and then emails us the results each morning at 7am.  

3 parts:  

Date Token Calculator:  We use this to take today's date and format it to fit what the repository wants for the search m/dd/yyyy.  

Search Repository:  Just the syntax of our search with the Date Token replacing the dates.  I generally fill any search field with 999999 or 99/99/9999 just makes it easier to replace with your variable/token.

Email:  Then just email the end user with the info they need.  It can be as simple as a Result Count from the search repository task or as complex as you want to make it with the filenames, etc..
