Klearbox vs Clean Email vs Unroll.me — An Honest Comparison
March 15, 2026 · 1 min read
There are several tools that claim to clean your inbox. They work differently, charge differently, and — critically — treat your data differently. Here's a straight comparison.
Unroll.me
Unroll.me lets you unsubscribe from newsletters and roll others into a digest. It's free. The catch: Unroll.me sold anonymised inbox receipt data to third parties including NielsenIQ. The FTC reached a settlement over this practice.
Clean Email
Clean Email is a more capable tool that supports multiple providers (Gmail, Yahoo, Outlook). It uses OAuth. Pricing starts around $9.99/month or $29.99/year. Email content passes through their infrastructure.
Klearbox
Klearbox is purpose-built for one thing: moving old Yahoo emails to Trash in bulk. It doesn't read email content. It uses IMAP metadata (sender, date, subject). Nothing passes through Klearbox servers in readable form.
Klearbox uses App Passwords — not OAuth. EU-hosted (Sweden). GDPR compliant. Free plan: 500 emails per run. Pro: €19/year.

Which should you use?
If privacy is the priority and you use Yahoo, Klearbox is the right choice. App Passwords instead of OAuth, no email content processed, EU-hosted.
