Install Gmail One-Click Cleaner, run a Light or Normal cleanup, and let it bulk-delete old promotions, social mail, and large attachments. Most users free up several gigabytes on the first run. Why is my Gmail storage so full? Gmail counts every email and every attachment against your 15 GB Google account quota, which is shared with Google Drive and Google Photos. Years of newsletters, promotional emails, and large attachments add up fast. Can I really delete thousands of Gmail emails at once? Yes. Gmail One-Click Cleaner uses Gmail's own bulk-action interface to select and trash hundreds or thousands of matching emails per pass, with safety guardrails so it never touches starred or important mail. Is it safe to bulk delete Gmail emails with this extension? Yes. Emails go to Gmail Trash first (recoverable for 30 days), Safe Mode protects receipts and shipping confirmations, and you can run Dry-Run Mode to preview every deletion before anything happens. Does this extension work on Outlook, Yahoo, or iCloud Mail? No. Gmail One-Click Cleaner is built specifically for Gmail and Google Workspace inboxes. Will it delete emails I want to keep? The default settings skip starred, important, and unread emails. You can also add senders or domains to the global whitelist so they are never touched, and Review Mode lets you approve every batch before deletion. Is Gmail One-Click Cleaner really free? Yes. The extension is free and open source, with no paid tier and no premium features. Source code is on GitHub. ► OPEN SOURCE & TRANSPARENT Full source code, documentation, and changelog: https://github.com/TiltedLunar123/gmail-one-click-cleaner
