Product Design

Gmail Case Study

September - December 2022

Overview:
This was a semester-long project for a class called Introduction to Digital Product Design. We were tasked with identifying a problem space and creating a solution for an existing application. I chose Gmail.

Three years later, Google independently shipped a feature that closely mirrors what I built.

Hypothesis: People lack control over what info they receive

Experiment: Gmail Subscription page

Observation

Listen, I [was] a busy college student, and I can't have my time wasted. So how does Gmail get away with it?
I scroll through my Primary inbox, trying to gather important bits of information as I read the subject lines on my screen:

[INFO 3300] New Assignment Released
Cornell’s New Mechatronics Certificate
Score Free Delivery @ Jack’s Grill 🚗
48 hours for 15% off rides
Laura, it’s time to book that Thanksgiving trip!

Wait... what? How is this in my Primary inbox?
‍
I have too many subscriptions living in my inbox that have gone out of control. Some understand that their home is the (unchecked) Promotions tab, yet some sneak into my Very Important Primary inbox. Why is this so?

Gather Background Info

User Research

First, I wanted to learn the different ways in which people interact with their inbox, and manage the content they receive. From my research, I found a spectrum for how people managed their inboxes:

Unread emails at 0

Astronomical amounts of unread emails

In my user research, I was lucky to talk to users that fall in either end of the spectrum. However, I found some common patterns among all users.

Common patterns

Mainly stay in Primary inbox

Only declutter when it becomes overwhelming or necessary

Most had no idea what their Promotions tab contained

Create a Hypothesis

If Gmail users gain more control over the emails they receive, then they will be able to use Gmail more efficiently and feel less overwhelmed by their inboxes.

Defining the Problem

The problem is the lack of control they have on the information they receive. This is why inboxes that are mostly filled with emails a user can’t control are considered full of “junk” and “pointless” information because they don’t know what there is, and there is too much of it.

As a busy college student, I want to check my emails quickly so I can catch up on information. But I can’t do that well because:

It’s hard to know how many subscriptions you have.
I get overwhelmed with too much mail in my inbox.

Test Hypothesis

Brainstorming

I led the brainstorming session with peers to ideate on solutions that would address user needs. We considered ways in which users would want to have control over their emails and thought about different user interactions that would be helpful in picking the right solution.

In the end, the solution I ended up going with was a list view of subscriptions with unsubscribing features. This specific solution would best support the features that should be implemented.

Market Research

Yahoo Mail was a competitor that had a centralized subscription page. This inspired me to create something similar for Gmail. From Yahoo, I was able to think of some important features that would be useful for my own subscription page:

Sender's name
Sender's email
Filtering
Option to unsubscribe immediately

Image of phone with Yahoo subscriptions page. Page has 2 tabs: Active and Unsubscribed. Active tab is open. Tab shows multiple subscriptions with each subscription having a name, email, amount of emails monthly, and the option to unsubscribe. There is an option to filter subscriptions at the top.

Entry Points

Before deciding what the subscriptions page could look like, I first had to decide how to get to the subscriptions page itself. Here were some considerations

'Unsubscribe Box': This existing feature appears when you don't open an email from a particular sender after 30 days. Fits with subscription management + shows that Gmail has an internal subscription tracker.
Sidebar: This entry point fits with the other email-related functions. Placement in sidebar matters for context.
Bottom Bar: Universally accessible. However, other products are other Google product integrations.

I ultimately went with the unsubscribe box and the sidebar entry points. The unsubscribe box is a great entry point since it deals with subscription management, and is relevant to the problem at hand. However, since it appears infrequently and is dependent on behavior (not opening emails for 30 days), there needs to be a more consistent and reliable entry point. That is why the sidebar is another entry point. It is an industry standard, and already hosts other entry points for other email-related functions.

Prototype of bottom bar from Gmail with subscriptions icon added to it. Icons are: Mail, Subscriptions, Chat, Meet, and Call.

Mid to High Fidelity

After considering the entry points, I had to update the designs to match the way Gmail behaves by leveraging Google's design system and interactions to maintain UI and behavioral consistency.

In this flow, the unsubscribe box now matches the way it looks in the app. You can enter the subscription page from the 'three-dot' entry point that is found across other Google products.

Sidebar Entry: Fits with other email related functions. Moved to the bottom since top links are for entering specific types of inboxes.

Unsubscribe Box: Expanded existing feature by adding "three dot" button on top right, similar to other Google features.

Swipe to Unsubscribe: Swipe a specific subscription the way you would to delete a single email.

Tap to Unsubscribe: Tap the icons to select subscriptions to mass unsubscribe.

This prompts the entry to be selected, and the top bar to change to show options to unsubscribe, manage subscription, and delete all emails from Cornell Chronicle. Cursor then undoes selection.

Analyze Results

User Testing

After testing the prototype with three different users, there were some minor changes made.

Subscription selection bar: Before, the spacing was inconsistent with different devices, and had unclear icons. The category management icon was confusing. This was changed to a simple gear to show that there can be settings changed for subscriptions.
Sidebar Entry: My first consideration for the sidebar entry was a dropdown under promotions tab. This was confusing to the users, who suggested simply putting the subscription entry point at the way bottom.

Final Prototype

Considerations and Conclusions

KPIs and Future Features

At launch, these would be the KPIs I'd monitor to consider its success at launch and shortly after:

Feature Adoption Rate: Tracks how many users actively engage with the Subscriptions page after discovery, the clearest signal that the feature addresses a real need.
Inbox Cleanliness Index: Measures the reduction in promotional emails reaching the Primary inbox over time, directly quantifying whether subscription management is working.
Net Promoter Score: Gauges whether users find the feature valuable enough to recommend, a leading indicator of long-term retention impact.

Further development would focus on category management expansion and search function integration within the Subscriptions page.

Further Observations

In Fall 2025, Google shipped a native subscription management feature for Gmail that bears a striking resemblance to the prototype I independently designed in 2022. The entry points, list view structure, and unsubscribe interactions closely mirror the solution I arrived at through this process. I documented the similarities in a LinkedIn post comparing the two side by side.

Conclusion

The most important design decision in this project wasn't visual, it was knowing what not to solve. Gmail's subscription problem isn't a categorization problem or a filtering problem. It's a visibility and control problem. Users didn't know what they were subscribed to, and they had no centralized place to act on it.

Right problem, simple solution > Wrong problem, elaborate solution:
Solving the right problem simply is more effective than solving the wrong problem elaborately. Identifying control as the core issue influenced every decision from that constraint: the entry points, the list view, the unsubscribe interactions. Solving for the right problem (control) was more effective than solving the wrong problem (filtering, categorizing) elaborately.
Existing design systems ≠ constraint:
This feature is part of an existing application. I had to learn how to adapt and create my solutions such that it fit within an existing design system. Working within Google's existing design system sharpened something important: good design in an existing product is about fitting in so seamlessly that users feel the feature was always there.
Good product design is verifiable:
The same user pain, the same gap, and the same logical process led Google to an independently similar solution in Fall 2025.

That was a lot! Jump to top?
