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
- 240 manual delete sessions
- No date filtering
- No sender filtering
- 4 hours of your life
- Give up and live with it
- 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

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

“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.

“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.
