Why "Mimeo"?
Before photocopiers, printing lived at the print shop — professional equipment, professional prices, a toll on every copy.
Then the mimeograph put the whole apparatus on a desk. Ink the drum, turn the crank: as many copies as you need. Owning the machine made everyone a publisher.
Email marketing rebuilt the print shop — your audience and your automations, rented back to you at a price that grows with your list.
