Quick Answer: If Gmail stops receiving mail on your iPhone while it still works on a computer, the account connection on the phone has broken — most often because a password change or two-factor authentication invalidated the saved credentials. Fastest checks: pull down in the inbox to force a manual sync, confirm Settings → Apps → Mail → Accounts → Gmail → Mail toggle is on, and set Fetch New Data to Push/every 15 minutes. If mail still won’t arrive, remove the Gmail account and add it back — that reissues the authentication token and fixes the majority of stubborn cases.
Your laptop shows the emails. Your iPhone shows “You’re all done” and an inbox frozen in time. Sending works fine — it’s only receiving that’s broken, which is exactly the pattern that makes people think their phone is possessed.
It isn’t. When Gmail sends and doesn’t receive on an iPhone, one of four things is happening: the account’s authentication has expired, the Mail sync toggle or fetch schedule is off, the mail arrived but got filtered somewhere you’re not looking, or the app’s background access is blocked. The ten fixes below check them fastest-first — starting with two that take a few seconds.
Find Your Situation
| Symptom | Most Likely Cause | Jump to Fix |
|---|---|---|
| Works on computer, not on iPhone | Account connection on the phone | Fix 3 & 8 |
| Stopped right after a password change | Saved credentials now invalid | Fix 8 |
| Stopped after an iOS update | Authentication token or sync reset | Fix 3, 7 & 8 |
| Mail arrives late, not never | Fetch schedule / Background App Refresh | Fix 4 & 5 |
| Some senders’ mail missing only | Filters, spam, or blocked addresses | Fix 6 |
| Nothing arrives on any device | Google-side: storage full or outage | Fix 9 & 10 |
How to Fix Gmail Not Receiving Emails on iPhone
Fix 1: Force a Manual Sync
The five-second first move — it tells you whether syncing is merely stalled or genuinely broken.
- Open the inbox and swipe down from the top to pull-to-refresh.
- Watch for the spinner. New mail appearing means sync had stalled — go to Fix 4 to stop it recurring.
- Nothing at all? Continue below.
Fix 2: Check the Connection and Restart
- Open a website to confirm the internet actually works.
- Toggle Airplane Mode on for ten seconds, then off — this alone revives stuck mail sync surprisingly often.
- Restart the iPhone if the inbox is still frozen.
Fix 3: Confirm Mail Is Switched On for the Account
The single most-missed setting: your Gmail account can be added to the iPhone with Mail turned off — calendar and contacts sync fine while no email ever arrives.
- Settings → Apps → Mail → Mail Accounts (on older iOS: Settings → Mail → Accounts).
- Tap your Gmail account.
- Make sure the Mail toggle is green. If it was off, that’s your answer.
Fix 4: Set Fetch New Data Correctly
Gmail accounts on iPhone often use fetch rather than push — set to “Manually”, mail only arrives when you open the app.
- Settings → Apps → Mail → Mail Accounts → Fetch New Data.
- Turn Push on at the top if available.
- Set the schedule to Automatically or Every 15 Minutes — not “Manually”.
- Tap your Gmail account within that screen and choose Fetch (rather than Manual) for it specifically.
Fix 5: Allow Background App Refresh and Notifications
If you use the Gmail app rather than Apple Mail, iOS background limits are the usual culprit for mail that only appears when you open the app.
- Settings → General → Background App Refresh → on, and enabled for Gmail.
- Settings → Apps → Gmail → Notifications → Allow Notifications on.
- Turn off Low Power Mode (Settings → Battery) while testing — it suspends background fetching.
Fix 6: Look Where the Mail Actually Went
“Not receiving” is often “not seeing” — Gmail sorts aggressively.
- Check Spam and All Mail, plus the Promotions and Updates tabs in the Gmail app.
- On a computer, open Gmail → Settings → Filters and Blocked Addresses — a filter set to archive, delete, or skip the inbox catches specific senders silently.
- Also check Settings → Forwarding and POP/IMAP: forwarding with “delete Gmail’s copy” makes mail vanish from every device.
Fix 7: Update iOS and the Gmail App
- Settings → General → Software Update — mail-sync bugs after major iOS releases are common and get patched.
- Update the Gmail app in the App Store if you use it.
- Restart after updating, then test with an email sent from another account.
Fix 8: Remove and Re-Add the Gmail Account — the Big One
This fixes most stubborn cases, because it reissues the authentication your iPhone uses. It’s the standard outcome when a password change or newly enabled two-factor authentication invalidated the saved credentials.
- Settings → Apps → Mail → Mail Accounts → tap Gmail → Delete Account (your emails live on Google’s servers — nothing is lost).
- Restart the iPhone.
- Settings → Apps → Mail → Mail Accounts → Add Account → Google, sign in, complete two-factor if prompted, and enable Mail.
- Let it sync for a few minutes before judging.
Fix 9: Check Google Account Storage
A full Google account stops accepting new mail entirely — senders get bounce messages and you get silence.
- Check your storage at Google One / Google Drive storage settings.
- Full or nearly full? Clear big Drive files and old Gmail attachments (search
has:attachment larger:10Min Gmail), then empty Trash and Spam. - Photos usually eats the space — worth checking there first.
Fix 10: Rule Out Google’s Side
- Check the Google Workspace Status Dashboard or Downdetector for Gmail outages.
- Send yourself a test email from another address — if it never appears on any device, the problem isn’t your iPhone at all.
Still Not Receiving?
- Reset Network Settings (Settings → General → Transfer or Reset iPhone → Reset) — it clears the network configurations mail sync depends on. You’ll re-enter Wi-Fi passwords; mail and data stay intact.
- Try the other app. If Apple Mail won’t receive, install the Gmail app (or vice versa) — it isolates whether the problem is the app or the account. A working Gmail app with a broken Apple Mail points straight at the account setup in iOS.
- Check IMAP is enabled in Gmail’s web settings (Settings → Forwarding and POP/IMAP → Enable IMAP) — Apple Mail can’t sync without it.
- Calendar not syncing either? The same account-authentication causes hit calendars — our Outlook calendar not syncing guide covers the parallel fixes, and much of it applies to Google accounts too.

Frequently Asked Questions
Why can I send but not receive Gmail on my iPhone?
Sending and receiving use different paths — outgoing can work while the incoming sync is broken. The usual causes are expired account authentication (after a password change or new two-factor setup), the Mail toggle being off for the account, or a fetch schedule set to Manual.
Will deleting my Gmail account from iPhone delete my emails?
No. Your mail lives on Google’s servers; removing the account from the iPhone only removes the local connection. Everything reappears when you add the account back.
Why did Gmail stop working on my iPhone after an iOS update?
Updates can reset sync settings or invalidate stored authentication tokens. Check the Mail toggle and Fetch settings first, then remove and re-add the Google account — that reissues authentication cleanly.
Why do emails arrive late on my iPhone?
That’s fetch scheduling, not a fault: with fetch set to Manually or long intervals, mail only arrives on that schedule. Set Fetch New Data to Push or Every 15 Minutes, and allow Background App Refresh for the Gmail app.
Can a full Google account stop emails arriving?
Yes — when Google account storage is full, incoming mail is rejected entirely and senders receive bounce notices. Clear Drive files, large attachments, and Photos to free space.
