Trimbox's iOS app gives you the first 10 unsubscribes free and needs Premium for unlimited. Premium pricing isn't published on its website and varies by platform, so check the store listing you use. Gnuke is free for 10 nukes a month, and Unlimited is $2.99 a month (paid plans aren't on sale yet).

Does Trimbox delete old emails from a sender?

Yes. Its FAQ says it offers one-click deletion of a sender's past emails, to Trash. It also creates Gmail filters to block senders.

Gnuke vs Trimbox: two Gmail unsubscribe tools compared

Q: Who owns Trimbox now?

Mode.Inc acquired Trimbox, with the deal completed on December 23, 2025 according to Mode's SEC filing. Mode announced plans to add its EarnOS engine so users can opt in to share "consented inbox and purchase data" for rewards.

Q: Does Trimbox sell my data?

Trimbox's site says it never shares or sells your email data. Its privacy policy includes both "We do not sell your Personal Information" and "We may sell or share information, including personal information," so read the policy before you sign up. Gnuke sells nothing, and no Gnuke server sees your mail.

Trimbox is the closest thing to Gnuke: a Gmail unsubscribe tool you add to Chrome, with a one-click way to remove a sender's old mail. Trimbox has more users and an iPhone app. Gnuke gives you a 30-day Undo and keeps everything on your own device.

The short version#

Both tools unsubscribe you, clear a sender's past email to Trash, and can block future mail with a Gmail filter. The differences are around the edges: ownership and data plans, how much you can keep, whether the work happens on your device, and where each one runs.

The real differences#

Ownership and the data plan#

Mode.Inc acquired Trimbox, and the deal completed on December 23, 2025, according to Mode's SEC filing. Mode announced plans to add its EarnOS engine so users can opt in to share "consented inbox and purchase data" for rewards (Pulse 2).

That is opt-in on paper. It does change what the product is for. In our view, a tool whose owner is building a data network around inboxes has a different incentive than one that only charges for the cleanup. Trimbox's home page says it never shares or sells your email data, and its privacy policy contains both "We do not sell your Personal Information" and "We may sell or share information, including personal information." Read the policy in full before you decide.

Gnuke has no data program. It reads message metadata (sender, subject, unsubscribe headers, read or unread) in your own browser or phone, and opens a message body only when it has to find an unsubscribe link the headers don't carry. See the privacy policy.

Undo and what stays#

A one-click delete is only comfortable if you can reverse it. Gnuke records what it moved and Undo restores it for 30 days. You can also protect mail ahead of time: starred mail always stays, and you can keep labeled mail, important mail, or a sender's newest 1, 3 or 10 emails. Senders you "always keep" are never offered for nuking.

We didn't find an Undo window or keep options described in the Trimbox sources we read. They may exist; check the app.

Extras that Gnuke adds#

Clean up scans your newsletters and promos and ranks senders by how many emails they sent and how often you open them, with labels like "Never opened" and "Quiet for 6+ months." You can tick several and nuke them together. "Still emailing you" flags senders who keep mailing more than 3 days after you unsubscribed, with a one-click Block. You can also nuke a whole domain (not for shared providers like gmail.com). New mail checks, part of Unlimited and in beta, tell you when 25 or more new emails are worth nuking or a nuked sender is back.

Where Trimbox is better#

It has a native iOS app, rated 4.7. Gnuke's phone version is a web app you add to your Home Screen.
Its Chrome extension has 60,000 users and a 4.4 rating on the Chrome Web Store. That is a longer track record than Gnuke's.
Its free tier is stated plainly in the App Store: your first 10 unsubscribes.

Who should pick which#

Pick Trimbox if you want a native iPhone app and you've read the current privacy policy and are comfortable with Mode's plans.

Pick Gnuke if you want Undo for 30 days, keep rules, a Clean up view for ranking senders, and no server touching your mail. Look at how it works and pricing before you install.
