The morning Gmail stopped working
It started with a bounce. A client emailed me to say my reply had bounced back to them, and when I tried to send a new message Gmail refused. New mail had stopped arriving too. I had hit the wall every free Google account eventually hits: the 15 GB storage limit, and I had no idea what was eating it, because my inbox did not look that big.
Here is the thing most people do not realise until this happens to them. Your free Google account includes up to 15 GB of storage, and that space is shared. Gmail, Google Drive and Google Photos all draw from the same pool. When the pool fills, three things stop at once: you cannot send or receive email in Gmail, and messages people send you bounce back to the sender; you cannot upload or create files in Drive; and Google Photos stops backing up new photos and videos from your phone until you free up space or upgrade.
Ignoring the warning is not a safe plan either. Google's storage guidance states plainly that if your account stays over its quota for two years, Google might delete your content across Gmail, Drive and Photos, and it says it will contact you at least three months before content becomes eligible for deletion. The cleanup below took me about half an hour and freed roughly 10 GB without deleting a single thing I cared about. Here is the exact order, because the order is the whole trick.
Step 1: find out who is eating the space
Before you delete anything, find out which service is actually full. Open one.google.com/storage while signed in, and Google shows exactly how your 15 GB splits between Drive, Gmail and Photos. That tells you where to attack first. In my case the surprise was Photos: years of phone backups at Original quality had eaten more than half the pool, while Gmail itself was under 4 GB. Deleting emails first would have been working on the wrong problem.
Google's own storage page lists what counts: photos and videos backed up at Original quality; Storage saver photos and videos backed up after June 1, 2021; Gmail messages and attachments, including anything sitting in Spam and Trash; files you own in Drive, including PDFs, images and videos; Google Meet recordings; and Docs, Sheets and Slides files created or edited after June 1, 2021. One useful detail: Storage saver photos backed up before June 1, 2021 never count at all, so deleting those frees nothing.
One more check worth doing before you pay for anything: if your account was created on or after March 9, 2026, it starts with 5 GB, and the other 10 GB arrives only once you add and confirm a phone number. If a newer account says it is full at 5 GB, verify a phone number before paying for anything at all.
Step 2: empty all three trash folders, plus Spam
This is the quickest win in the whole cleanup, and the one most people skip. Deleted items in Drive, Gmail and Photos keep counting against your quota until they are permanently deleted, and years of forgotten trash can hide gigabytes. Empty the trash everywhere before you delete anything new at all.
In Gmail on a computer, open Trash, then click "Empty Trash now" in the notice at the top. Do the same in Spam. Then empty the trash in Drive and in Photos, which have their own. Gmail's Trash and Spam auto-delete after 30 days, and Drive's trash after 30 days, so anything older than that is already gone — but anything you deleted recently is still sitting there counting against you. In my case the three trash folders alone gave back nearly 2 GB, and I had not deleted a single live file.
One patience note from Google: after a big deletion your available space updates after a short period, and if the account still shows full after 30 minutes, that is the point to move on to the deeper cleanup. Some guides say the storage number can take 48 to 72 hours to catch up after a very large deletion, so do not panic if the meter lags behind your work.
Step 3: delete the biggest files first
Now attack the biggest service, starting with its biggest files. A few large items — big attachments, videos, backups, and trash folders never emptied — usually free more space than thousands of small emails, so do not start by deleting old newsletters one by one. That is the slowest possible way to do this.
In Google Drive, click Storage in the left menu on a computer. Your files are listed from largest to smallest. Download what you want to keep, delete the rest, then empty Drive's trash again. In my Drive the top of the list was old video exports and duplicate installers I had forgotten about — three files, over 3 GB, gone in two minutes.
For Gmail specifically, search by size, not by sender. Type has:attachment larger:10M into the Gmail search bar to list every email carrying a file over 10 MB, delete the ones you no longer need, then empty the Trash. Adding older_than:2y to the search surfaces the heavy old mail first. The emails I deleted were mostly ancient: presentation decks from 2019, raw photos a client had sent me twice, a video file someone had emailed instead of linking. Before deleting any attachment I wanted to keep, I saved it — and here is the catch to remember: saving it to Drive still counts against the same 15 GB pool. To actually reclaim the space, save the file off the account entirely, as a local download or to a second account's Drive, and then delete the email.
Step 4: the Photos and backup traps
If Photos is your biggest user, as it was for me, there are two specific traps. First, WhatsApp and Android device backups draw on the same 15 GB pool, and an old phone backup can sit there for years. Check your backups in Google One or Drive and delete the ones for phones you no longer own. Second, Original quality photo backups count in full, while Storage saver quality is compressed and far smaller. Switching future backups to Storage saver does not shrink what is already there, but it stops the bleeding, and Google One's storage manager can show you the large videos in Photos that are worth downloading locally and removing.
Google One's storage manager is the tool that ties this together. On a computer, open Google One and click Storage, then "Free up account storage" to see specific cleanup suggestions, or "Clean up suggested items" for the biggest wins. On a phone, the Google One app has the same tool: tap Storage, then "Free up account storage". One warning Google gives, and it matters: in the storage manager, Gmail and Drive items are deleted for good right away. Only Photos items go to a trash first. Double-check before you confirm.
Step 5: decide whether to pay, with real numbers
After the cleanup I had roughly 10 GB free, and I have stayed free since, because the cleanup also taught me where the space goes. But sometimes paying is the right answer, so here are the real numbers. Google One plans start at $1.99 a month for 100 GB and scale up from there. That is about $24 a year to stop thinking about storage entirely, with the extra space shared across Gmail, Drive and Photos.
My rule is simple: pay if the cleanup does not get you at least 3 GB of headroom, or if your storage grows faster than about 1 GB a month and you would be doing this cleanup every few weeks. Do not pay if a one-time cleanup reclaims several gigabytes, because the clutter that filled the account was mostly trash and duplicates, and paying would just let the clutter grow in a bigger bucket. A one-time cleanup costs nothing and takes half an hour. A subscription costs $24 a year forever. Do the free thing first, then decide with a clean meter in front of you.
And set a guardrail so you do not end up here again. I switched my phone's photo backup to Storage saver, I delete the Drive trash monthly, and I run the has:attachment larger:10M search every few months. Storage is a leak, not a flood, and a leak you check twice a year never becomes a crisis.
Conclusion
Freeing 10 GB from a full Google account is a half-hour job if you do it in the right order: check one.google.com/storage to see which service is actually full; empty all three trash folders plus Spam, because deleted items still count; delete the biggest files in Drive and the biggest attachments in Gmail with has:attachment larger:10M, saving anything you need off the account first; and clear the old Photos and device backups that quietly eat the pool. Only then decide whether Google One's $1.99 a month for 100 GB is worth it.
The morning Gmail stopped sending my emails felt like a crisis. It was a chore I had been postponing for years, and it took less time than a phone call to fix. Do it this week, before the next bounce. Your future self, the one whose email actually arrives, will thank you.
FAQ
How much free storage does a Google account include?
Up to 15 GB, shared across Gmail, Google Drive and Google Photos. Accounts created on or after March 9, 2026 start with 5 GB until a valid phone number is verified, which unlocks the other 10 GB.
What happens when Gmail storage is full?
You cannot send or receive email, and messages sent to you bounce back to the sender. Drive uploads stop, and Photos stops backing up. If the account stays over quota for two years, Google may delete content across Gmail, Drive and Photos.
How do I find the biggest emails in Gmail?
Type has:attachment larger:10M in the Gmail search bar to list emails with attachments over 10 MB. Add older_than:2y to surface the heavy old mail first. Delete what you do not need, then empty Trash.
Do deleted emails still count against Gmail storage?
Yes, until they are permanently deleted. Items in Trash and Spam keep counting, and Gmail auto-deletes Trash and Spam after 30 days. Empty both manually to reclaim the space immediately.
How much does Google One cost?
Google One plans start at $1.99 a month for 100 GB, shared across Gmail, Drive and Photos. Clean up first — most accounts can reclaim several gigabytes for free — and pay only if the cleanup does not leave enough headroom.
How long does Gmail storage take to update after deleting?
Google says the available space updates after a short period, and some guides report it can take 48 to 72 hours to fully catch up after a very large deletion. Wait at least 30 minutes before assuming the cleanup did not work.
