The Problem

Yahoo Mail gives you no way to clean your inbox.

Yahoo only lets you delete 100 emails at a time — manually. With 24,000 unread messages, that's 240 separate delete sessions by hand. Even if you're fast, that costs you 4 hours of your life. Most people give up.

24,000 emails ÷ 100 per operation = 240 separate delete sessions — 4 hours of your life

Without KlearBox
  • 240 manual delete sessions
  • No date filtering
  • No sender filtering
  • 4 hours of your life
  • Give up and live with it
With KlearBox
  • One click, thousands of emails
  • Filter by date, sender, subject
  • Live progress in real time
  • Done before your coffee's cold
  • Schedule it monthly, automatically

Clean your inbox in three steps

1

Generate a Yahoo App Password in 2 minutes. Enter it in KlearBox. That's it. No OAuth, no broad access, no sharing with Yahoo.

2

Filter

Choose a folder. Set how old emails must be. Preview exactly what will be moved before touching anything.

3

Clean

Click once. Watch thousands of emails move to Trash in real time.

What users say

Had 40,000+ unread emails. KlearBox cleared them in about 20 minutes. I'd been putting this off for years.

Mark D.

Yahoo user since 2005

I was about to lose my Yahoo account because of the storage cut. This saved me. Simple to set up, did exactly what it said.

Sandra K.

Retired teacher

No login with Yahoo, no broad permissions — just what it needs and nothing more. Finally a tool I actually trust.

Your emails never leave your account.

No data stored

We never read, copy, or store your email content or metadata. Not the sender. Not the subject. Nothing.

No OAuth

Most apps ask for OAuth — granting broad access to your entire Yahoo account. We don't. An App Password is a 16-character token you generate yourself, with IMAP-only access to move emails. Delete it from Yahoo in seconds to instantly cut off all access.
