How to Mass Delete Emails in Gmail (2026)

Quick answer: To mass delete emails in Gmail, run a search (like category:promotions or from:sender@example.com), click the select-all checkbox at the top, then click "Select all conversations that match this search", and hit the trash icon. This deletes every matching email, thousands at once. Then empty Trash to actually free up storage. This only works on the desktop or browser version of Gmail.

Below are the exact methods, plus a faster way to delete by sender across your whole inbox.

Method 1: Mass delete using Gmail search (free)

This is the core trick most people miss. The select-all checkbox at the top of Gmail only selects the ~50 emails on the current page, until you click one extra link.

1. In the Gmail search bar, enter a search that matches what you want to delete (examples below).
2. Click the checkbox at the top-left to select everything on the page.
3. A banner appears: "Select all conversations that match this search." Click it.
4. Click the trash icon. Confirm if prompted.

Gmail now deletes every email matching your search, not just the visible page.

Useful searches for mass deletion

All promotional email older than a month:

category:promotions older_than:1m

Everything from a specific sender:

from:newsletter@example.com

Social notifications:

category:social

Old email you'll never reopen:

older_than:2y

Large emails eating your storage:

larger:10M

Tip: Always archive important threads first (or apply a "Keep" label), then run your deletion searches. Archived email leaves your inbox but stays searchable.

Method 2: Mass delete by sender (the fast way)

Search-by-search deletion works, but you have to know what to search for, and you'll repeat it dozens of times. The real bottleneck is that Gmail never shows you a ranked list of who is filling your inbox.

That's what MailMop does. It analyzes your entire inbox in your browser and shows every sender ranked by how many emails they've sent and how much space they use. From there you can:

• Bulk delete every email from a sender in one click
• Select multiple senders and delete them together
• Unsubscribe so they stop sending
• Keep the senders that matter and clear the rest

Because most clutter comes from a few dozen senders, this turns an hour of search-and-delete into a couple of minutes, and your email never leaves your browser. (MailMop users have deleted over 2 million emails this way.)

Method 3: Delete everything and start fresh

If you want a truly empty inbox, see our dedicated guide on how to delete all emails in Gmail. The short version: search in:inbox, select all matching, and delete. Back up anything important with Google Takeout first.

Don't forget: empty Trash

Everything you "delete" goes to Trash and keeps counting against your 15GB storage for 30 days. To reclaim space now:

1. Open Trash (in the left sidebar, you may need to click "More")
2. Click "Empty Trash now"

If your goal was to free storage, also clear large attachments first. See Gmail storage full? How to free up space.

Mass deletion mistakes to avoid

• Deleting on mobile. The app can't select all matching emails. Use a browser.
• Forgetting to empty Trash. No storage is freed until you do.
• Keyword-deleting personal mail by accident. Prefer deleting by sender so you can see exactly what goes.
• Deleting instead of unsubscribing. The newsletter comes back tomorrow unless you unsubscribe.

Key takeaways

• The magic step is "Select all conversations that match this search." Without it you only delete one page.
• Deleting by sender is faster and safer than deleting by keyword.
• Always empty Trash to reclaim storage.
• A tool like MailMop does sender-based bulk deletion in minutes, in your browser.
