A management system for managing a data transmission destination comprises an accumulation unit configured to accumulate, when data transmission is performed, transmission information of the data transmission as collected data; a generation unit configured to generate training data including a pair of ground truth data containing transmission destination information, and input data containing an item other than the transmission destination information, from the collected data accumulated in the accumulation unit; a processing unit configured to generate, by machine learning, a learning model to be used to predict a transmission destination, by using the training data generated by the generation unit; and a providing unit configured to provide a prediction process using the learning model in response to a request.
