In 1753, the creator of the e-newsletter’s predecessor didn’t want his service to scale

Alan Jacobs writes that newsletter creators like The Atlantic’s Alexis Madrigal  are following the “stock and flow” approach of an 18th century personal note-writer.  A German friend of Rousseau and others summarized works of philosophy or literature or social criticism and then described how those works were being received. His audience was never to be everyone — he wrote for his  influential subscribers like Catherine the Great of Russia, Frederick II of Prussia, and several other European kings, princes, and aristocrats.
