Gmail storage almost full? Here's why search won't fix it.

Gmail shows your total storage used but not which senders are responsible, so it’s hard to tell. It’s often a small number of senders with large attachments or thousands of accumulated newsletters. EmailSlim scans your mailbox metadata and ranks senders and domains by total storage used, so you can see exactly what is filling your space.

Gmail’s free 15GB is shared across Gmail, Google Drive, and Google Photos, so email is only part of the pool. Within Gmail, attachments and years of accumulated messages count toward the limit — and because Gmail doesn’t show storage per sender, the biggest space-wasters are easy to miss.

Delete the emails from your biggest senders, then empty Gmail Trash. Deleted emails keep counting toward your quota until Trash is emptied, so that last step is what actually reclaims the space right away.

No. EmailSlim never deletes anything without your approval — all deletions happen in your Gmail when you click delete, and they go to Gmail Trash first, where they stay recoverable for about 30 days.

No. EmailSlim works in any browser with nothing to download. You sign in with your Google account via OAuth, it analyzes metadata only (sender, date, size — never your email content), and you start with a free scan of your first 500 emails, no credit card required.
