People look for more personalized experiences, and new ways to live more sustainably. What if the mailbox could be reimagined and work as an enabler for all those things? This is the idea behind the modular mailbox. A future-looking prototype constituted by a combination of different modules, connected to each other in different configurations adapting to the situation, with core modules focused on shopping, sharing and sustainability. The modular mailbox also enables third-party partners to build additional modules to serve specific needs and experiences. Each modular mailbox is a part of a bigger, connected network, where all modular mailboxes, and the services they enable, are connected and easily accessed digitally. The modular mailbox features four core modules: The in- and outbox, the recycling box, the 3D-printer box and the sharing box.
