Google Storage Full and Gmail Stopped Getting Email? Fix It in This Order

A red banner in the Gmail app says you're out of storage, or someone texts you that their email to you bounced. Here's what's going on: Gmail, Google Drive and Google Photos share one pot of storage (15 GB on a free account). When it's full, Google says you can't send or receive email, and messages sent to you go back to the sender. That's a bad week for it to happen, with order confirmations, shipping notices and Black Friday receipts (November 27 this year) all on the way.

The fastest fix, in Google's own order: empty Gmail's Trash and Spam, empty Drive's Trash, then delete one or two emails with very large attachments. That's usually enough to get mail flowing again within half an hour. Then you can work out what actually filled it.

First: which "storage full" is it?

iPhone owners can see three different warnings, and fixing the wrong one does nothing:

• Google storage full (this post): the warning shows up in Gmail, Drive or Google Photos, and email stops arriving. Deleting photos from your iPhone's Photos app won't help, unless those photos are also backed up to Google Photos.
• iCloud storage full: an Apple message about iCloud backups or iCloud Mail. See how to fix iCloud storage full.
• iPhone storage full: Settings says the phone itself is out of space and the camera or updates stop working. See iPhone storage full.

To see what's using your Google storage, sign in at drive.google.com/settings/storage in Safari. It splits the total into Gmail, Drive and Google Photos, so you know where to start.

Step 1: Empty Gmail Trash and Spam (2 minutes)

Google says email in Trash and Spam counts against your limit until it's permanently cleared, and calls emptying them "the quickest way to recover space." If you recently deleted a lot of mail, it's still sitting in Trash for up to 30 days, still counting.

In the Gmail app on iPhone:

1. Tap Menu (top left), then Trash.
2. Scroll through quickly. Anything in here is gone for good once you empty it.
3. Tap Empty trash now at the top.
4. Do the same in Spam. If you don't see the button in the app, open Gmail in a browser, go to Spam and click Delete all spam messages now.

Step 2: Empty Drive's Trash (2 minutes)

Google Drive keeps deleted files in its own Trash for 30 days, and they count toward your storage until then. In the Drive app: tap Menu, then Trash. Check there's nothing you want back, then tap More (top right) and Empty trash.

Step 3: Delete a few huge emails (5 minutes)

You don't have to delete thousands of newsletters. Ten old emails with 20 MB video attachments free more than 10,000 promotions with no attachments. Google suggests these searches:

• has:attachment larger:10M finds emails with attachments over 10 MB.
• older_than:2y has:attachment finds attachments more than two years old.
• filename:.pdf larger:5M finds big PDFs.

Google's instructions for this step are written for a computer (Gmail in a browser). If you only have your iPhone, try the same text in the Gmail app's search bar. Save anything you need first, like a scanned ID or a contract, then delete those emails. Then empty Trash again, or the space doesn't come back.

Step 4: Wait, then check again

Google says your available space updates "after a short period," and to try the deeper cleanup if you're still full after 30 minutes. After a big delete, it can take 48 to 72 hours for the number to catch up. Ask someone to send you a test email. If it arrives, you're back under the limit.

If you're still over: the deeper cleanup

Google Photos

If you ever turned on backup in the Google Photos app, your camera roll may be filling Google storage and iCloud at the same time. Be careful here. Google says deleting photos in the Google Photos app also deletes them from your iPhone. If you use iCloud Photos, that delete can sync to your other Apple devices too. If you only want the Google copy gone, read what Google Photos' Free up space does and doesn't do first.

Drive files

On drive.google.com, the Storage page lists your files from largest to smallest. Old phone backups, video exports and duplicate uploads are the usual suspects. Delete them, then empty Drive's Trash again.

Or buy more space

If everything there is worth keeping, a paid Google One plan raises the limit. That's a fair choice. Just don't let it sit over the limit. Google says that if an account stays over quota for two years or more, all of its content may be removed. Google promises at least three months' notice first.

Where Phone Diet helps, and where it doesn't

We make Phone Diet, so here's an honest answer: you can do all of the above for free in Gmail and Drive. Phone Diet only works on the Gmail part of the problem.

Connect your Gmail and it sorts mail into groups: Promotions, Social, Updates, Spam, Large Emails (attachments of 5 MB or more) and Never Read (unread and over a year old). Each group shows a count and an estimated size, so you can see in a minute whether email is really your problem. Starred mail is left alone unless you choose otherwise. Scanning is free. Clearing email needs Premium.

Two limits to know:

• It moves mail to Gmail's Trash. It never deletes it permanently. That's a safety choice: you get 30 seconds to undo, and Gmail keeps it in Trash for 30 days. It also means your storage doesn't drop until you empty Trash (Step 1).
• It can't touch Google Drive or Google Photos. If the storage page says Photos or Drive is the big one, the steps above are the fix, not an app.

If the iPhone itself is full as well, that's the part Phone Diet is built for. It scans your photo library on the phone for duplicates, bursts and long videos.

Quick answers

Why did Gmail stop receiving email?

Your Google Account is over its storage limit. Google says that means you can't send or receive, and mail to you bounces back to the sender. Drive and Photos can fill it even if your inbox is small.

Do Trash and Spam really count?

Yes. Gmail's Trash and Spam and Drive's Trash all count until they're emptied.

Will deleting email free up space on my iPhone?

Barely. Google storage and iPhone storage are separate. Email cleanup fixes the Google warning, not the iPhone one.

Will people who emailed me while I was full get through later?

Not on their own. Google says mail sent while you're full goes back to the sender. Once you have space, ask anyone you're waiting on, like a store or a shipping company, to resend. Or check your order page on their website.
