On a phone, “Select all” in Gmail sounds final. On Android it selects up to 50 messages, and you have to tap it again for the next 50. Clearing a few thousand emails that way takes a long time and is easy to lose track of.
In the Gmail app, search for the mail you want gone, touch and hold one message, tap Select all, check the count, then tap Delete. For more than a few hundred messages, use Gmail in a computer browser, where one link selects every match.
Before you delete anything
- Check the account. Tap your profile picture (top right) and confirm it is the one you mean to clean.
- Star or label mail you must keep: receipts, contracts, tax forms, recovery codes.
- Remember that deleting removes the mail on every device signed in to the account.
Android: select and delete a batch
- Open the Gmail app.
- Search for the batch, or open a folder such as Promotions.
- Touch and hold one message to start selecting.
- At the top left, tap the box next to Select all. Gmail selects up to 50 messages by default (Google).
- To add 50 more, scroll to the top and tap Select all again.
- Check the number at the top of the screen.
- Tap Delete (the trash icon).
If your app looks different, use the selection it shows. Gmail updates its layout often.
iPhone: select and delete a batch
- Open the Gmail app (not Apple Mail).
- Search for the batch or open a folder.
- Tap the sender picture next to a message to select it, then tap the others.
- If a Select all option appears at the top, check the count before using it.
- Tap Delete (the trash icon).
Apple’s own Mail app has different controls. If you read Gmail in Apple Mail, follow the Apple Mail guide.
Searches that make a clean batch
The Gmail app accepts the same search operators as the desktop (Google). Type them in the search box at the top.
| Search | What it finds |
|---|---|
from:[email protected] | One sender (replace the address) |
category:promotions older_than:1y | Promotions older than a year |
category:social | Social network notifications |
older_than:2y | Everything older than two years |
has:attachment larger:10M | Large messages that use storage |
Shortcut: the free Gmail Cleanup Search Builder builds these searches for you, with starred and important mail left out.
Open a few results before you select. A store can send receipts as well as sale alerts, and a familiar sender can have one email you still need.
When a phone is the wrong tool
Use Gmail in a computer browser when:
- The search returns more than a few hundred messages
- You want to delete everything in a category, such as all Promotions
- You need to check the exact total before deleting
On a computer, Gmail offers a link to select all conversations matching the search, not only the ones on screen. A phone browser can open the desktop site, but it is awkward on a small screen.
Empty Trash, or leave it
Deleted messages stay in Trash for 30 days before Gmail removes them (Google). Until then they still count toward your Google storage.
To empty it on Android: Menu › Trash › Empty trash now. Check what is there first. After emptying, the mail cannot be recovered.
To rescue something: open Trash, touch and hold the message, tap More › Move to, and choose a folder.
Archive is not delete
Swiping a message may archive it instead of deleting it, depending on your swipe settings. Archived mail leaves the inbox but stays in All mail and keeps using storage. On Android, change them under Menu › Settings › General settings › Swipe actions (Google).
Keep it from piling up again
- Unsubscribe from lists you delete every week. In the app, Menu › Manage subscriptions shows them all.
- If your account is full, use the Gmail storage guide to target large mail.
- Keep a short weekly email reset.
On a computer you can clear much more at once. The Gmail search cheat sheet has ready-made searches you can paste into the search bar.
