There are no clear origins of the concept of junk mail – it’s almost as old as the postal service itself. Companies are often offered lower prices for their mail costs due to the bulk nature of their stamps and envelopes. This means businesses have been using the mail service for years to reach their customers en masse.
Although the presence of junk mail is lessening due to a combination of environmental factors and the existence of email, plenty of businesses still implement this method to reach older customers who may not be contactable digitally.
