Gmail can't receive emails? Check your storage first

Last reviewed: August 29, 2026 · Markdown version

When a Google account runs out of storage, mail stops in both directions. Google's help page puts it plainly: "You can't send or receive emails. Messages sent to you go back to the sender." People writing to you get bounce messages, and nothing waits for you — so this is worth fixing fast, and worth fixing right.

Step 1 — confirm storage is actually the cause

Open one.google.com/storage, signed in to the affected account. If the bar shows you at or over your limit, storage is your problem — and the same page shows which product (Photos, Gmail, or Drive) is holding the space, which decides where to clean. If storage looks fine, the cause is something else entirely (filters, forwarding rules, a client sync issue) and nothing on this page will help — check Gmail's own settings instead.

Step 2 — the fastest safe space recovery, in order

1. Empty Gmail's Trash and Spam. Both count against your storage until permanently cleared; Google calls clearing them the quickest way to recover space. Trash → "Empty Trash now", then the same in Spam. Emptying is permanent — glance through Trash first if you've recently deleted anything you might want back.
2. Empty the other two Trashes. Google Photos (Library → Trash) and Google Drive each keep their own — deleted items sit there for weeks and keep counting.
3. If Photos holds the space: convert to Storage saver. photos.google.com → Settings → Manage storage → Recover storage compresses your backed-up photos (16 MP / 1080p caps) and is usually the single biggest recovery on a photo-heavy account. The conversion is not reversible — keep originals elsewhere if you need full resolution. More: the Photos page.
4. If Gmail holds the space: delete heavy attachments. Search has:attachment larger:10M, delete, then empty Trash again — deleted mail frees nothing until Trash clears. At whole-inbox scale, see what works for Gmail cleanup.

Two timing facts that prevent panic

• The meter lags. Google says storage totals can take up to 48–72 hours to update after deleting a lot at once. Receiving usually resumes once you're genuinely under the limit — don't judge success by the bar in the first hours. Background: why deleting doesn't free space instantly.
• Bounced mail is not waiting for you. Messages sent while the account was full were returned to their senders. Once you're back under the limit, important correspondents may need to resend — worth telling them, since they saw the bounce and you saw nothing.

Keeping it from happening again

If the space was photos or Drive files, the fixes above are the whole answer — revisit them when the bar creeps up. If the space was email, the underlying cause is usually years of newsletters, promotions, and receipts arriving daily, and the durable fix is clearing that backlog and unsubscribing from what keeps refilling it. On a computer, Gmail's own search + select-all can do it. On a phone — where Gmail has no select-all — Zen Inbox Cleaner groups your mailbox by sender so you can clear thousands of emails and unsubscribe in a few taps, on your device, reading only email metadata. That's the specific case we can help with; everything else on this page is Google's own tooling, free.
