-Based on this information, the approximate number of messages/day is 19,920 (83*10*24), and the byte size is 6MB (25K*10*24). The size estimate is based on the default response field set. Changing the response field set (refer to [Fields](/logs/logpull/requesting-logs/#fields)) will change the response size.
