Systems and methods for personalizing electronic messages for users based upon determining user mobile device location data indicating user locations within an area of interest are disclosed. User geospatial location data is obtained at user mobile devices upon the triggering event of a user action (e.g., visiting a web site or using an application on the user mobile device). The location data is stored and compared against map data accurately and precisely defining a map area of the area of interest, such as a vehicle dealer lot. A user data sheet is generated to store information regarding the user location and time at the area of interest. The user data sheet may include a user status identifier based upon elapsed time since the user was at the area of interest. Personalized messages are then generated and transmitted to the user based upon the information in the user data sheet.
