Problem Statement  

How can we create an easy-to-use and effective solution that helps email users unsubscribe from unwanted subscription lists, declutter their inboxes from unnecessary emails, and identify all the websites linked with their email addresses?

Problem Background  

Email users receive dozens of unnecessary emails every day, cluttering their inboxes and reducing their productivity. D.KLUTR addresses this problem by providing a simple and effective solution for unsubscribing from unwanted emails and identifying websites linked with email addresses.

The customers for our product are email users who receive a significant amount of unwanted subscription emails, cluttering their inboxes and making it difficult to manage their email effectively. The problem we aim to solve is the issue of email overload, where email users are inundated with a large volume of unwanted emails, including subscription lists, spam, and promotional emails.

According to a study conducted by the Radicati Group, the number of emails sent and received per day worldwide is expected to reach 392 billion by the end of 2026, and is projected to continue to grow over the next few years. According to a survey of online users in the United States, almost 6 in 10 percent of respondents reported believing that the majority of the emails they received are not useful, while 54 percent of respondents reported thinking they receive too many emails. 

There are also several existing solutions in the market that address the problem of unwanted emails, including email filters and spam blockers. However, these solutions do not always effectively manage subscription emails, which are often not considered spam but can still contribute to email overload.

Research Insights

User Pain Points

We administered a survey via Google forms and received 31 responses and conducted 3 user interviews. 

The main pain points were:

  • Overwhelming amount of emails received
  • The amount of time it takes to go through emails
  • The numerous steps needed to unsubscribe
  • Emails tend to come back even after unsubscribing

Supporting Data

  • 48% of respondents had over 1000 unread emails in their inboxes
  • 36% declared it was too timely to manually delete and unsubscribe from lists
  • 45% reported that they currently manage their inboxes by ignoring the mail
  • 22% expressed that the return after unsubscribing


The research showed that many users simply delete emails to keep their inbox clean, while others ignore them or unsubscribe, only to have them resurface later. The sheer amount of emails received makes the process overwhelming. Time-consuming processes and frustration with the number of steps involved in unsubscribing were common issues. Additionally, a significant percentage of users would like the solution to identify all websites linked to their email addresses, and ideally, it should be a one-click option.

Landing on the Solution

The research highlights the need for a simple and effective email management solution (preferably a mobile app) that can help users declutter their inboxes and unsubscribe from unwanted emails quickly and easily. With further development and improvement, such a solution could be a game-changer for email users who struggle to manage their inboxes effectively.
