The company, working with Royal Mail and Microsoft, lets you send correspondence directly from a computer to any UK address. You download a driver from ViaPost’s Website, type the letter on your computer, and choose ViaPost as your printer option. The letter is sent digitally to the ViaPost office nearest to your destination address. The letter is printed and sealed automatically, and delivered by Royal Mail.
So mail no longer has to travel hundreds or thousands of miles before it reaches the recipient which leads to “a greener and more secure postal service,” according to Greenbang.
