Letter sorters are machines or devices used to organize and distribute mail efficiently. They can automatically sort letters based on size, weight, or destination, helping postal services and businesses manage large volumes of mail quickly. This technology reduces the time and effort required for manual sorting. In addition to traditional mail, letter sorters can also handle packages and other types of correspondence. They are commonly found in post offices and large organizations, where they streamline the process of delivering mail to the correct locations. This ensures that letters reach their intended recipients promptly and accurately.
