About this extension
Gmail storage full? Bulk delete old emails and large attachments, then bulk unsubscribe from the mailing lists flooding your inbox, to free up gigabytes of Gmail storage in minutes. Free bulk cleanup, open-source, 100% private, and every run can be undone in one click.

Gmail One-Click Cleaner is the fastest way to clean up your inbox: mass delete old emails, large attachments, promotions, and newsletters, and bulk unsubscribe from the senders that keep refilling it, so you can stop paying for Google One storage upgrades. A built-in storage analyzer shows exactly which senders are eating your space, and one-click Restore puts back anything you change your mind about. Reclaim space across Gmail, Google Drive, and Google Photos without losing the messages that matter.

Not sure where to start? Run the free Mailbox Report first. It counts what is actually sitting in your mailbox and ranks it, biggest win at the top, so you get a plan you can work through one step at a time.

Tired of seeing "Gmail storage almost full" or "Google Drive storage full"? Replace hours of manual searching and deleting with a bulk cleanup you watch on a live progress dashboard, then stop the flood at the source with one-click bulk unsubscribe.

► WHY USE GMAIL ONE-CLICK CLEANER?

• Free bulk cleanup, no subscription: skip Google One and the monthly fees other inbox cleaners charge
• Know what to delete before you delete it: the free Mailbox Report counts your clutter and ranks it
• Bulk delete thousands of emails at once: no more selecting 50 messages at a time
• Bulk unsubscribe from mailing lists: stop new promotions and newsletters before they arrive
• See what's actually eating your space: the free Storage X-ray ranks senders by how many megabytes they hold
• Undo button included: restore an entire cleanup run to your Inbox with one click
• Built specifically for Gmail: works directly inside mail.google.com, no shady inbox forwarding
• 100% local and open source: every line of code is on GitHub for anyone to inspect

► MAILBOX REPORT: SEE WHAT'S IN THERE BEFORE YOU DELETE ANYTHING

Most people open a cleanup tool with no idea whether the problem is ten years of newsletters or one folder of enormous PDFs. The Mailbox Report settles that in about a minute, before you touch anything.

• One read-only pass, about a dozen Gmail searches, nothing opened and nothing moved
• Counts every kind of clutter separately: old promotions, social and forum mail, forgotten newsletters, big attachments in three size tiers, and mail that has sat in your Inbox for years
• Ranks the results biggest first, so the step that frees the most space is the one at the top
• The whole report is free, and so is running its biggest step, so you watch it work on your own mail before deciding anything
• Every step runs as an ordinary cleanup: labeled first, into Trash, your whitelist and protected keywords respected, and logged for one-click Restore
• Pro clears the remaining steps, or runs the entire plan in a single pass
• Honest numbers only: storage figures are counted at each size tier's floor, so the report says "at least" and means it. It never pretends to know how much of your 15 GB is Drive or Photos, because no extension can see that.

► BULK DELETE OLD EMAILS & FREE UP GOOGLE STORAGE

• Finds and mass deletes emails with large attachments eating into your shared Google storage quota
• Bulk removes old Promotions, Social notifications, Newsletters, and automated alerts. Recent and important mail stays safe.
• Clears Gmail storage and reclaims gigabytes without upgrading to Google One: a free alternative to paid Google storage plans
• Replaces tedious manual inbox cleanup with a guided progress dashboard that does the work for you
• Deletes by age, size, sender, category, or your own Gmail search query

► STORAGE X-RAY: FIND WHAT'S EATING YOUR GOOGLE STORAGE

"Storage almost full" never tells you what to delete first. The Storage X-ray answers by sender.

• Free read-only scan: walks Gmail's own size searches (25 MB, 10 MB, and 5 MB tiers) and shows the total space you can reclaim plus your top space hogs
• Honest numbers: every email is counted at its size tier's floor, so the estimate is a defensible "at least", not marketing math
• Full ranked sender list and one-click purge (Pro): clear out the senders you pick, with an age filter that keeps recent mail out of it
• A purge is a normal cleanup run: tagged first, lands in Trash, respects your whitelist and every guardrail, and shows up in the Recovery Log

► BULK UNSUBSCRIBE FROM MAILING LISTS

Deleting old mail clears space; unsubscribing stops the flood. Gmail One-Click Cleaner does both.

• Scan your inbox to see every mailing list emailing you, ranked by how much they send (free, read-only, changes nothing)
• Bulk unsubscribe from the senders you never read in a single pass, instead of hunting for tiny "unsubscribe" links one email at a time
• Uses Gmail's own built-in Unsubscribe control, never sketchy links inside message bodies
• Senders with no one-click option are flagged for manual follow-up, never guessed at
• The privacy-first alternative to Unroll.me and other unsubscribe services: your inbox is never forwarded, scanned, sold, or stored elsewhere

► SAFE BY DESIGN: DELETE WITH AN UNDO BUTTON

• 100% local: all cleanup, scanning, and unsubscribing run in your browser. No email content, metadata, or personal data is ever sent to any external server.
• Trash-first deletion: emails are moved to Gmail Trash, never permanently erased
• One-click Restore: every run is labeled before it moves, so the Recovery Log can put an entire run back in your Inbox with one click. Deleted runs stay restorable for the ~30 days Gmail keeps Trash; archived runs can come back any time.
• Smart safety guardrails: automatically skips starred, important, and unread emails. Safe Mode protects receipts, order confirmations, and shipping updates.
• The guards are yours to change: all four switches sit in the popup, so a mailbox that has never been cleaned can turn them off for a deeper sweep.
• A very large run stops and asks: if a sweep is about to touch more than ten thousand conversations, the progress dashboard asks first, with "stop the run" as the default answer. No answer means no run.
• Global whitelist: lock specific senders or domains so they are never touched
• Works in 17 languages: drives Gmail's interface in English, Spanish, French, German, Portuguese, Italian, Japanese, Korean, Chinese, and more. On a language it doesn't know, it stops and says so instead of clicking the wrong thing.
• Open source: every line of code is publicly available on GitHub. Inspect it yourself before you install.

  4. When it finishes you get the count, the labels it applied, and a link to the Recovery Log: if anything went that shouldn't have, one click restores the whole run to your Inbox

► HOW IT COMPARES TO OTHER GMAIL CLEANUP TOOLS

Looking for a Clean Email alternative, Mailstrom alternative, or Unroll.me alternative? Gmail One-Click Cleaner is the privacy-first, no-subscription option:

• No monthly fee: cleanup is free and Pro is a one-time $9.99, not a recurring subscription like Clean Email or Mailstrom
• No third-party server: your inbox is never forwarded, scanned, sold, or stored elsewhere, unlike unsubscribe services that monetize your data
• No account creation: just install the extension and run it
• Open source: audit the code yourself or fork it on GitHub
• No tracking, no ads, no data collection of any kind

► FREQUENTLY ASKED QUESTIONS

How do I delete all emails in Gmail at once, or thousands of them?
Install Gmail One-Click Cleaner, pick a rule set, and run it. The extension uses Gmail's own bulk-action interface to select and trash matching emails hundreds or thousands per pass, instead of deleting 50 at a time by hand. Safety guardrails keep it off your starred and important mail, and Dry-Run Mode previews exactly what will be removed before anything happens.

Can I undo a cleanup or restore deleted emails?
Yes. Every run labels its mail before moving it, so the Recovery Log can restore an entire run with one click: the extension searches the run's label and moves everything back to your Inbox using Gmail's own controls. Deleted runs stay restorable for the ~30 days Gmail keeps Trash; archived runs have no deadline.

How do I bulk unsubscribe from emails in Gmail?
Run the free subscription scan to list every mailing list emailing you, ranked by volume. Select the ones you never read and unsubscribe from all of them in one pass. It uses Gmail's own built-in Unsubscribe control, so it is safe and never touches sketchy links inside the emails.

What should I delete first?
Run the free Mailbox Report. It counts each kind of clutter separately, ranks them so the biggest win is at the top, and lets you clear that first step for free. You see real numbers from your own mailbox before you decide anything.

Why is my Gmail storage so full, and how do I free it up without paying for Google One?
Gmail counts every email and attachment against your 15 GB Google account quota, which is shared with Google Drive and Google Photos. Years of newsletters, promotions, and large attachments add up fast. Run a Light or Normal cleanup and let it bulk-delete old promotions, social mail, and large attachments. Most users free up several gigabytes on the first run.

Why doesn't my storage go down right away after deleting?
Because nothing is permanently erased. Deleted mail goes to Gmail Trash, and Google keeps Trash for about 30 days before the space comes back. That delay is the safety net: it is the window in which one-click Restore can put an entire run back in your Inbox. If you want the space immediately, empty Trash yourself in Gmail once you are happy with the result.

Which senders are using the most of my Gmail storage?
Run the free Storage X-ray. It walks Gmail's size searches and ranks senders by how many megabytes they hold, so you can see whether the space is going to old newsletters, years of PDFs, or one attachment-happy sender before you delete anything.

Is it safe to bulk delete Gmail emails with this extension?
Yes. Emails go to Gmail Trash first, Safe Mode protects receipts and shipping confirmations, Dry-Run Mode previews every deletion before anything happens, and the Recovery Log can restore a whole run to your Inbox with one click.

Does it work on non-English Gmail?
Yes. The cleaner works in 17 languages, including Spanish, French, German, Portuguese, Japanese, Korean, and Chinese. On a language it doesn't cover, it fails safe: it stops and tells you instead of guessing at buttons.

Does this extension work on Outlook, Yahoo, or iCloud Mail?
No. Gmail One-Click Cleaner is built specifically for Gmail and Google Workspace inboxes.

Is Gmail One-Click Cleaner free?
The bulk cleanup, scheduling, custom rules, the whole Mailbox Report and its biggest step, the subscription scan, the storage scan, Smart Suggestions, and one-click Restore are free forever, with no subscription. Pro is an optional one-time $9.99 unlock for the rest of the report plan, bulk unsubscribe, the full Storage X-ray, the full suggestion list, and Auto-Pilot. Source code is on GitHub.
