- Scan in 30 seconds — Our engine analyzes all emails by size, age, category, and sender.
- Clean with one click — Delete thousands of junk emails at once. No browser crashes.
- Undo anytime — 30-day undo restores emails to their original Gmail labels.

Security & Privacy
We only access email metadata — sender, date, size, and labels. We never read email content, attachments, or body text. OAuth tokens are AES-256 encrypted. Our app passed Google's OAuth security review. Revoke access anytime. No ads, no data selling.
Gmail vs Smart Mailbox Cleaner
Gmail can't: find all emails over 10 MB, filter by size + date + category at once, bulk delete entire categories in one click, restore deleted emails to original labels, schedule automatic cleanup, export emails from any label, or manage multiple accounts in one place. Smart Mailbox Cleaner can do all of this and more.
