The United States Postal Service(LISPS)is offering a way to people who are interested in seeing tomorrow’s mail today．The postal service will send consumers images(图像)of their letters，magazines and other mail before they arrive．The new service is called Informed Delivery．It is an attempt to remain competitive in an ever—changing world．

Postal service officials say the increased use of email，digital messaging services and social media has made it difficult to stay relevant．David Rupert is a media relations specialist who spoke about the competition the agency now faces．Whether you turn on a television or your computer，or people come to your door with different products and services，all of those are competing for consumers’time and energy，he said．

Interested users are first required to sign up for Informed Delivery．Once registered，the consumer receives a daily email with virtual(虚拟)images of letters or other things to be delivered．The US Postal Service says it can especially help those who have a mailbox at their local post office，so they know when to get their mail：

Another postal offering is a service that seeks to make advertising-related mail-often called junk mail—more fun．The service uses virtual and augmented reality(虚拟现实和增强现实)to let consumers interact with their junk mail．Many companies put special coding on their advertising，which can give users an interactive experience．Some companies even put virtual reality eyeglasses in the mail to make their ads come to life．Consumers have mixed reactions to virtual and augmented reality advertising．“You can find some good things within junk mail．It is a good idea．We’11 see how it works，”Postal service user Victor Teah said．But Jocelyn Coatney doesn’t think it would change her mind about junk mail．“For some，that might be fun．But for me，it would be useless，”she said．
