Gmail Storage Full: How to Free Up Space and Get Email Working

When your Google storage runs out, Gmail is usually the first thing to break: new messages stop arriving, and people who email you get a bounce saying your inbox is out of space. The fix is to free up space — but the space isn't only Gmail's, which is why clearing a few emails often doesn't help.

How Gmail storage works

• Every Google Account includes up to 15 GB, shared across Gmail, Google Drive and Google Photos.
• In Gmail, every message and attachment counts — including the Spam and Trash folders.
• Files in Google Drive and backups in Google Photos use the same 15 GB, so they're often the real reason Gmail is full.

On a work or school account, storage is set by your organisation; if you run out, ask your administrator.

What happens when you're out of space

• Google says your ability to send and receive email in Gmail can be affected. You can still sign in.
• People who write to you may get a bounce such as 452 4.2.2 The recipient's inbox is out of storage space. If the account is also inactive, Gmail returns 552 5.2.2 instead.
• If an account stays over its limit for two years or longer, Google may delete its content in Gmail, Photos and Drive. It sends at least three months' notice first.

Check what's using your storage

Open the storage page in your Google Account or the Google One app to see how much Gmail, Drive and Photos each use. Start with whichever is largest — it's frequently not Gmail.

Free up space in Gmail

1. Empty Spam and Trash. Google calls this the quickest way to recover space: messages in those folders keep counting until they're permanently deleted.
2. Find large messages. Type has:attachment larger:10M in the Gmail search bar to list messages with attachments over 10 MB, or filename:.pdf larger:5M for large PDFs. Delete what you don't need — then empty Trash again.
3. Save attachments you want to keep to your computer before deleting the message.

Free up space in Drive and Photos

• Delete large files you own in Google Drive. Files that are only shared with you use their owner's storage, not yours.
• Remove photo and video backups you no longer need from Google Photos.
• Delete old device or app backups from the storage management page at one.google.com/storage/management.

Buy more storage

If you need to keep everything, upgrading to a Google One plan adds storage to the whole account — Gmail, Drive and Photos together. For an account that's important to you, this is often quicker than clearing years of mail.

After you've freed up space

New mail starts arriving again once you're under the limit. Because Gmail answers senders with a temporary code (452), their servers keep retrying for a while, so some messages may still arrive after you've made room. Anything that finally bounced has to be sent again — let people know if you were full for long. If mail still isn't arriving, work through Gmail troubleshooting.
