Phishing emails claiming a Google account's 15 GB of free storage is full direct users to a fake upgrade page that harvests Google credentials and payment card details.

Last reviewed: 7 June 2026
Google provides 15 GB of free storage shared across Gmail, Google Drive, and Google Photos. As this limit is frequently approached by long-term users who have accumulated years of emails, photos, and documents, a 'storage full' alert is both plausible and anxiety-inducing. Scammers craft fake storage alerts that prey on this anxiety.
The genuine concern about losing the ability to receive emails or upload photos creates urgency: a full mailbox means missed messages, and lost photos represent irreplaceable memories. Attackers use this emotional weight to push victims toward quick action without careful verification.
Unlike simpler credential-theft phishing, storage upgrade scams often pursue payment card details as well as passwords, making the potential financial impact more severe.
How this scam works on the Google brand
Google sends genuine storage notifications from [email protected] directing users to one.google.com for storage management, or to google.com/settings/storage to purchase additional space via Google One. Google does not ask users to enter card details through a link in an email — upgrades are completed within the Google One section of your Google account.
Fake storage alerts replicate the visual language of Google's transactional emails: the colour bar showing storage usage, the categories breakdown (Drive, Gmail, Photos), and the 'Get more storage' call-to-action button. The button links to a fake Google One payment page at a domain such as google-one-storage-upgrade[.]com.
After entering Google credentials on the fake sign-in page, victims are presented with a realistic-looking Google One plan selection and then asked for full payment card details. Some campaigns also harvest the Google two-factor authentication code, enabling immediate account takeover.
Common red flags
- Storage alert email is not from [email protected] or a @google.com sender
- The 'Get more storage' button leads to a domain other than one.google.com or accounts.google.com
- The upgrade page requests full credit card details through a page reached via an email link
- You are asked to enter your Google password again as part of the 'upgrade' process
- The email shows a storage usage amount that does not match your actual usage at one.google.com
- Google Drive and Gmail on your device continue to function normally despite the 'full' alert
How to protect yourself
- Check your actual Google storage status at one.google.com — if it is genuinely full, upgrade directly there
- Google One upgrades are purchased within your Google account at one.google.com/storage, not through email links
- Consider using Google Takeout to download and delete old files before upgrading to free up space
- Enable Google's two-factor authentication and use phishing-resistant methods such as a hardware key or passkey
- Review your Google account security at myaccount.google.com/security-checkup after any suspicious interaction
How to report it
- Report phishing emails via the Gmail three-dot menu 'Report phishing' option
- Forward the email to [email protected]
- Report to the FTC at reportfraud.ftc.gov (US) or Action Fraud actionfraud.police.uk (UK)
- If card details were submitted, contact your bank or card issuer immediately
Frequently asked questions
How does Google notify me when my storage is genuinely full?
Google sends emails from [email protected] when your storage is approaching or has reached its limit. The email links to one.google.com where you can review usage and purchase additional storage. You will also see a warning banner inside Gmail and Google Drive.
Can emails stop arriving if my Google storage is full?
Yes. When Google storage is completely full, Gmail stops accepting new messages and Google Photos stops backing up. This is a real consequence of running out of storage, which is why these alerts carry genuine urgency — and why scammers exploit them.
How much does legitimate Google One storage cost?
Google One pricing varies by region and plan tier. You can check the current options at one.google.com/about/plans. Any email quoting prices should be verified against what you see at that official URL before making any payment.
