Delete everything, on a computer

  1. Open Gmail in a browser and click All Mail in the left column — Inbox shows only one tab.
  2. Tick the select box above the list.
  3. Click Select all conversations in All Mail in the banner that appears.
  4. Click Delete. Gmail moves them to Trash.

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.

Step 1 of 6On the Email tab, tap Sign in with Google. Phone Cleaner never sees your password, and your mail stays between this iPhone and Google.

Questions

Can I undo deleting all emails?

For 30 days. Open Trash, select the emails and choose Move to Inbox.

Does deleting emails free Google storage?

Yes, once they leave Trash. Gmail shares your Google storage with Google Drive and Google Photos — up to 15 GB at no charge. Accounts created from 9 March 2026 start with 5 GB and unlock another 10 GB by verifying a phone number.

Will it delete emails on all my devices?

Yes. Gmail syncs, so they leave every device.
