Project overview
The problem

The problem worth solving.

Most busy inboxes are full of newsletters subscribed to years ago and never cleaned up. Unsubscribing means opening each email, hunting for a tiny link and repeating it for every sender.

The tools that do this for you usually want access to your mail on their servers, which is a hard sell for anyone who cares about privacy.

Our solution & strategy
What we built

How it works.

We built a Chrome extension that connects to Gmail and analyses six months of message headers. It detects newsletters, groups them by sender and scores each one from 0 to 100 on how strongly you should unsubscribe, based on read rate, time since you last opened one, volume and age.

It never fetches email bodies, and all processing happens in your browser with no server in the middle. A popup shows an inbox health score and the top senders to drop, and a full dashboard adds search, sorting, charts and bulk selection.

Unsubscribe uses the sender's own unsubscribe link, opened for you to confirm, so nothing is sent silently.

1. Connect Gmail. Sign in with Google. Read-only access to message headers is enough.

2. Headers are analysed. Newsletters are detected and grouped by sender, locally in your browser.

3. Senders are scored. Each sender gets a score from read rate, recency, volume and age.

4. Review recommendations. See the senders most worth dropping, with a plain-language reason.

5. Unsubscribe in one click. Open the sender's unsubscribe link and confirm.
