Zen Inbox Cleaner
The Email Hoarder Calculator
Last reviewed: August 30, 2026 · Markdown version
How many emails are sitting in your inbox? Enter the number — get your storage damage, your cleanup time, and your official rank.
Runs entirely in your browser — no form submission, no network request, nothing stored.
Deleting emails frees storage only after Gmail's Trash clears — and if your account is full, the space may not be email at all. See Does deleting emails actually free up storage?
Or let the app do the tapping.
Zen Inbox Cleaner groups your Gmail inbox by sender, so you can trash bulk mail, newsletters, and promotions in one tap — and unsubscribe with one tap. It reads email metadata only (never bodies or attachments), everything happens on your device, and nothing is permanently deleted by the app — trashed email stays recoverable in Gmail's Trash for 30 days.
