Problem: Based on the several surveys we did, we found that most people were not able to connect the digital carbon footprint with emails. Besides, they did not spend much their time on cleaning up their mailbox often. Thus, the main problem we needed to figure out is how we focus on email’s negative impact on the environment and provide tools to users for organizing emails efficiently.

​

Process: After several user surveys and research regarding Gmail, the most significant obstacle was that people was not aware of the shortcut for deleting emails that Gmail actually provided. Thus, we decided to create a tutorial for both environmental education and how to use the shortcut to delete emails. In the brainstorming process, we turned all the useful information from the previous interviews into sticky notes through the Affinity diagram on Miro. Then we continued working on lo-fi and hi-fi prototype. During the modifying process of the prototypes, we repeated the user tests including moderated remote testing and one-click testing to make sure any added icons or content is noticeable to most users.
