Gmail One-Click Cleaner by SecPlusMastery

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 who really fills your mailbox: the free sender census counts your top senders one by one
• Check the unsubscribe worked: every unsubscribe is dated, then verified against Gmail two weeks later
• 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.

► SENDER CENSUS: WHO ACTUALLY FILLS YOUR MAILBOX

Most cleanup tools describe your mailbox with a search written before they ever saw it: promotions, big attachments, anything over a year old. If your mailbox is not shaped like that search, the tool reports almost nothing and does almost nothing. Plenty of mailboxes are tens of thousands of small, ordinary messages from a few dozen senders, and no category search names them.

• Free read-only census: samples widely, sliced by age and by whether you ever opened the mail rather than by category, then counts each sender that keeps coming up with its own Gmail search
• The number beside a name is Gmail's own answer about that sender, not a guess from one page of results
• Every row also shows what clearing that sender would actually remove today, measured through the same filters the button applies, so the count and the button cannot disagree
• Clearing the senders you tick is Pro, and it only ever touches senders you ticked yourself
• Ticked senders keep getting cleaned on your ordinary and scheduled runs, so a weekly sweep keeps reaching them

► DID THEY ACTUALLY STOP? UNSUBSCRIBE VERIFICATION

Every unsubscribe tool sends the request and greys out the row. So does Gmail. Nobody goes back to find out whether the sender stopped, and plenty of them do not.

• Every unsubscribe you run here is dated, and the ledger is free to keep
• After a two-week grace window, one Gmail search per sender answers whether anything new arrived
• Senders who ignored you get a button that deletes only what they sent after their window closed
• Senders who kept mailing but landed in Spam are named too, where an ordinary Gmail search cannot see them. Nothing is deleted for those: the extension will not point a delete at Spam, where Gmail's own control means gone for good.
• Senders who stopped and later started again are called out separately, because that is the one you would never think to check
• A verdict is never invented from silence: if a search does not resolve, it says so instead of reporting that they stopped

► 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 across five tiers, from 25 MB all the way down to 100 KB, and shows the total space you can reclaim plus your top space hogs
• Small mail counts too: a mailbox made of thousands of ordinary messages is exactly the case a 5 MB floor misses entirely
• 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: it reads Gmail's own buttons and menus in whatever language your account is set to. 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.

► 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
• It checks the unsubscribe worked: sending the request is where every other tool stops, including Gmail's own
• 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 know an unsubscribe actually worked?
The extension dates every unsubscribe you run, waits two weeks, then searches that sender again and tells you what it found. Senders who ignored you can be cleared in one click. Senders who kept mailing but got filed as spam are named separately, because an ordinary Gmail search does not look in Spam and would otherwise report them as having stopped.

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.

How do I stop getting so many promotional and newsletter emails?
Deleting them clears space but they keep coming back. Bulk unsubscribe stops them at the source: scan your inbox, pick the senders flooding it, and unsubscribe in bulk instead of clicking tiny unsubscribe links one email at a time.
