Trimbox is a Chrome browser extension that helps you unsubscribe from mailing lists in one click and mass-delete old messages from a sender. It runs locally and states that your email never leaves your device. It is focused squarely on unsubscribe and bulk-delete, primarily for Gmail.

How does PureBox compare to Trimbox?

Trimbox is a single-job unsubscribe extension. PureBox is a web app that does more: it shows important mail before cleanup, proposes Archive and Trash cleanups in plain language with a reason for each, and keeps a history. PureBox works directly with Gmail after approval; Trimbox keeps processing on your device, which some people prefer.

Does PureBox need a browser extension like Trimbox?

No. PureBox is a web app you sign into with Google OAuth - there is nothing to install in your browser. Trimbox is a Chrome extension. If you specifically want a local, on-device tool, Trimbox fits that model; if you would rather not add an extension, PureBox does not require one.

Can PureBox unsubscribe from mailing lists like Trimbox?

Bulk unsubscribe is not offered in PureBox today - that is Trimbox's core strength. PureBox focuses on showing important mail and proposing review-first Archive and Trash cleanups that you approve before they apply to Gmail. If one-click unsubscribe is your only goal, Trimbox may be the better fit; if you want broader triage, PureBox covers more of the job.

Is PureBox private like Trimbox?

Both take privacy seriously in different ways. Trimbox keeps processing on your device as a local extension. PureBox connects through minimum Gmail OAuth scopes, does not sell your data, and does not use it for advertising. Choose the model you trust more.

Beyond unsubscribe

Trimbox focuses on unsubscribing and mass-deleting senders. PureBox also shows mail worth reading before cleanup and explains each suggestion.

No browser extension

PureBox runs as a web app you sign into - nothing to add to your browser. Trimbox is a Chrome extension.

Review-first, with a history

You approve every suggestion before it moves. Approved actions happen in Gmail and show up in History.

When PureBox fits better than Trimbox

You want more than unsubscribe - important mail first, then review-first cleanup.
You would rather sign into a web app than install a browser extension.
You want a plain-language reason behind each suggestion before you approve it.
You want cleanup tailored to your own Gmail engagement, so a sender you regularly read is handled differently from one you never open.

When Trimbox may fit better

You mainly want fast one-click unsubscribe and nothing more.
You prefer that processing stays on your own device via a local extension.
You are comfortable working inside a browser extension rather than a web app.

We'd rather you find the right tool than the wrong subscription.
