Delete everything, on a computer
- Open Gmail in a browser and click All Mail in the left column — Inbox shows only one tab.
- Tick the select box above the list.
- Click Select all conversations in All Mail in the banner that appears.
- Click Delete. Gmail moves them to Trash.
Delete by sender or date
Most clutter comes from a few senders. Search from:sender@example.com, or older_than:1y for mail over a year old, then select all and delete.
On iPhone
The Gmail app selects up to 50 emails at a time, so deleting thousands there is slow going. A cleaner that groups mail by sender lets you move a sender's emails to Trash — and unsubscribe — in one go.
