Updater is nothing more and nothing less than an online service for handling offline mail. Users of this platform can deal with two big concerns: the change of physical mail addresses, and the filtering of junk mail. The former is made easy by filing an online USPS change of address form that can simultaneously update professional and personal contacts, and the latter is accomplished by giving users complete control over who is accessing their paper mail addresses. That is, by using a privacy address feature that creates a do-not-mail list people can bar marketers from contacting them with their “unrepeatable” offers.

This specific service comes at a cost – if you want to use Updater to block marketers from getting your address, you will have to pay $14.99. That fee will let you opt out of all the major marketing lists currently available, and also to implement a spam filter for your physical mail address for three full years.
