The Surprising Origins of Prepaid Mail
Before postage stamps existed, the person receiving a letter had to pay the delivery fee upon arrival. If they refused to pay or were not home, the sender was stuck with the cost and the undelivered mail.
This old system made mail unreliable and frustrating for everyone involved. To solve this, countries shifted to a prepaid model where the sender covered the costs upfront using small adhesive stamps. This simple change transformed the postal service from a complex collection business into a universal utility. Today, we take this convenience for granted, but it was a revolutionary shift in global communication.
