Email Reports and ISNOTBLANK

I have an App that allows users gather data from individuals in the field.
I would like to set it up so that every morning I get a report showing me all of the new data that was gathered the day before.
It seems I need to use and IF/THEN statement and ISNOTBLANK but I don’t want to get back True/False Any help is appreciated
