How to clean up Gmail on your iPhone

What Gmail storage actually counts

A Google account gets 15 GB free, shared between Gmail, Google Drive and Google Photos. Photos is usually the largest consumer, but a decade of mail with attachments runs to several gigabytes on its own.

The part people get wrong: deleting mail does not free the space immediately. Deleted messages go to Trash and stay there for 30 days, counting against your allowance the whole time. Spam works the same way.

So any clean-up finishes with the same two steps: empty Trash, then empty Spam.

Find the mail that is actually taking space

Type these into the Gmail search box. They work identically in the iOS app and on the web.

Start with larger:10M. A handful of messages there is often worth more than thousands of ordinary ones.

Bulk deleting in the Gmail iOS app

The iOS app has no select-all. You tap each sender avatar to select, one message at a time, which is why most people give up.

1. Run one of the searches above.
2. Tap the round avatar next to a message to select it.
3. Keep tapping avatars — only what is loaded on screen can be selected.
4. Tap the bin icon.

Workable for tens of messages. Not for thousands.

Bulk deleting properly, from Safari

The web version has the select-all that the app lacks, and it works in Safari on the iPhone if you request the desktop site.

1. Open mail.google.com in Safari.
2. Tap aA in the address bar → Request Desktop Website.
3. Run your search.
4. Tick the checkbox at the top left to select the visible page.
5. Tap Select all conversations that match this search — this is the link that matters.
6. Tap the bin, and confirm.

Fiddly on a phone-sized screen, but it is the only way to clear thousands of messages in Google's own tools.

Then: Trash → Empty Trash now, and Spam → Delete all spam messages now. Until you do, nothing has actually been freed.

Cleaning by sender instead of by message

Inboxes are not evenly distributed. A handful of senders — a retailer, a newsletter, a social network's notifications — usually account for most of the volume. Working sender by sender is far faster than working message by message.

iPhone Cleaner connects a Gmail account with Google Sign-In and groups the inbox by sender, showing how many messages each one has sent you and how much space they occupy. You delete everything from a sender in one action, and unsubscribe at the same time.

On the privacy question: sign-in uses Google's OAuth flow, so the app never sees your password. The access token is held in the iOS Keychain on your device, message content is processed on the device to do the grouping, and nothing is stored on a server or forwarded. You can revoke access at any time from your Google Account permissions page.

Unsubscribing so it stops

Deleting today's newsletter does nothing about tomorrow's. Legitimate senders include a standard unsubscribe header, which is what Gmail's own Unsubscribe link next to the sender name uses.

Use it whenever it appears. When it does not, the options are the link at the bottom of the message, or — for senders that ignore unsubscribes entirely — blocking them: open the message, tap the three dots, tap Block "sender". Blocked mail goes straight to Spam.

Expect a few days of lag. Senders are allowed a short window to process an unsubscribe, so a newsletter arriving the next morning is normal, and one arriving three weeks later is not.

Keeping it clean

• Unsubscribe on receipt. The moment a newsletter you do not read arrives, unsubscribe instead of deleting. It takes the same three seconds and it only has to happen once.
• Use a filter for bulk senders. In Gmail on the web, create a filter that archives or labels mail from a sender automatically.
• Check larger:10M once a year. A few minutes, and it is where the space is.
• Empty Trash and Spam after any clean-out. Otherwise you have waited 30 days for nothing.
