Cleanfox report card
Very good · out of 4.0 · graded Nov 12, 2026
Best for a free newsletter cleaner paid for by data
Cleanfox finds the newsletters in your mailbox and lets you delete or keep each one, for no charge. It's paid for by selling statistics compiled from the emails it scans, and signing up joins NielsenIQ's online consumer panel. It cleans subscriptions only and isn't an email client.
Who Cleanfox is for
- Fits if your inbox is full of newsletters you never read
- Works for people who accept the data trade for a free cleaner
Who Cleanfox is not for
- Not for you if you don't want your emails scanned, as the site says it sells statistics compiled from them
- Watch out: signing up joins NielsenIQ's online consumer panel, according to the site
- Skip it if you want an email client, as it cleans subscriptions only
- Watch out: the site says it can't connect to some providers
Why Cleanfox gets a 3.0
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- AValue for moneyEverything is free. The cost is not money: the site says it sells statistics compiled from the transactional emails and newsletters it scans.
- AFree plan and trialFree outright, with all features at no charge and no paid plan.
- CFeaturesNewsletter detection, delete or keep per sender, deleted mail goes to the bin, and several providers. It does that one job, a smaller job than an email client, and the site says it can't connect to some providers.
- CEase of useNo store rating on record. You connect your mailbox first, though it's one-click per newsletter after that.
- BPlatforms and integrationsWeb, iOS and Android, with Gmail and Outlook connections. No desktop app.

Keep Cleanfox, or make your own?
Keep it
Cleanfox is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces. It is one of the better ones too: its GPA of 3.0 is higher than 55 of the 70 other email apps we grade.
What you could not
- Connections to other products, each kept working as those products change.
- Filters that read every message as it arrives.
- A real app for iOS and Android. Something home-made would be a web page.
What this rests on. Cleanfox’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
