Gmail notifications not working is almost always caused by a switched-off permission rather than a broken app. Gmail alerts depend on a chain of three layers — Gmail’s own settings, your browser or phone’s permission system, and your operating system’s notification centre — and every link in that chain has to be switched on. This guide walks you through 8 fixes in order, from the quickest to the most thorough, so you can find the exact break and get your alerts back.

Quick checks
Before you touch any settings, run through this 60-second list. Most people find their problem here:
- Is your Gmail tab open in the browser? Desktop alerts cannot appear if the tab is closed.
- Are you signed in to the account you want alerts for? Notifications only fire for the active signed-in account.
- Is your phone’s Do Not Disturb or your PC’s Focus / Do Not Disturb mode switched on?
- Is your device’s volume muted? Some notification styles only play a sound.
- Are you connected to the internet? This sounds obvious, but alerts cannot arrive on a dead connection. If your PC keeps dropping its connection, our guide on fixing Wi-Fi problems on Windows 11 will help you stabilise it first.
- Do you have more than one Gmail account on the app? Each account has its own notification setting — check the right one.
Diagnose your problem
| Symptom | Likely cause | Go to fix |
|---|---|---|
| No alerts on your PC browser, but the phone app works | Gmail’s desktop notification setting is off, or the browser blocked the permission | Fix 1, Fix 2 |
| Alerts worked yesterday and stopped suddenly | Browser permission reset, Do Not Disturb switched on, or an extension is blocking them | Fix 2, Fix 4, Fix 7 |
| Phone gets no Gmail alerts at all | System-level notification permission off, or Gmail’s in-app level set to None | Fix 5 |
| Phone alerts arrive late, sometimes hours after the email | Battery optimisation is stopping Gmail from syncing in the background | Fix 6 |
| Only some emails trigger an alert | Inbox categories, labels, or “high priority only” filtering is hiding the rest | Fix 5 |
| Sound plays but no pop-up appears | OS notification banners switched off while sounds are allowed | Fix 3 |
| Alerts appear on one device but not the other | Each device needs its own permission chain switched on | Repeat Fixes 1–6 on the silent device |
1. Turn on desktop notifications inside Gmail
Gmail has its own master switch for desktop alerts, and it is easy to miss. If this switch is off, nothing else in the chain matters. Google’s own help documentation for enabling new email alerts confirms that this setting is the starting point for desktop notifications, and it is worth checking against the official Google guide to email notifications if you want the full reference.
- Open Gmail in your browser and make sure you are signed in to the account you want alerts for.
- Click the Settings gear icon in the top-right corner, then click See all settings.
- On the General tab, scroll down to the Desktop notifications section.
- Select New mail notifications on to get an alert for every new email, or Important mail notifications on if you only want alerts for important mail.
- If Gmail shows a “Click here to enable desktop notifications for Gmail” link, click it and allow the permission when your browser asks.
- Optionally, set Mail notification sounds to a sound you like.
- Scroll to the bottom of the page and click Save Changes. Skipping this step is one of the most common reasons the setting appears to do nothing.
Keep your Gmail tab open after this. Desktop alerts only appear while you are signed in with Gmail open in the browser.
2. Allow the browser to show Gmail notifications
Even with Gmail’s own switch on, the browser can still refuse to display alerts. Browsers treat notification permission as a per-site decision, so Gmail needs explicit permission to show pop-ups.
In Chrome:
- Click the padlock or settings icon in the address bar while on Gmail, then click Site settings.
- Find Notifications and set it to Allow.
- Alternatively, go to Settings > Privacy and security > Site settings > Notifications, and check that mail.google.com is in the Allowed list, not the Blocked list.
In Microsoft Edge:
- Go to Settings > Cookies and site permissions > Notifications and confirm Gmail is allowed.
In Firefox:
- Go to Settings > Privacy & Security > Permissions > Notifications, open Settings, and make sure mail.google.com is set to Allow.
In Safari:
- Open Safari > Settings > Websites > Notifications and set Gmail to Allow.
If you once clicked “Block” when the browser asked about notifications, Gmail will sit silently in the blocked list until you reverse that choice. This single blocked permission is the cause of a large share of “it used to work” cases. For more step-by-step guides to browser settings like this one, browse the TechSBSInfo blog.
3. Check your Windows notification settings
The third layer is your operating system. Windows can mute a specific app’s banners even when everything else is correct, and the symptom is usually “I hear a sound but see no pop-up” or nothing at all.
- Open Settings > System > Notifications (press the Windows key and type “notifications” to find it quickly).
- Make sure Notifications is switched on at the top.
- Scroll to Notifications from apps and other senders and find your browser (Chrome, Edge, Firefox).
- Turn that browser’s switch on, and click it to open its options.
- Make sure Show notification banners is ticked if you want visible pop-ups, and Play a sound when a notification arrives is ticked if you want audio.
- Check the Focus or Do not disturb settings on the same page and make sure they are not permanently silencing everything.
On a Mac, the equivalent path is System Settings > Notifications, where you enable notifications for your browser. On Android or iPhone, check the device-level notification permission for the Gmail app — the phone cannot show what the OS has been told to suppress.
4. Switch off Do Not Disturb and Focus modes
Do Not Disturb is the silent killer of notifications. It is easy to switch on by accident — a quick-settings swipe on a phone, a keyboard shortcut on a laptop — and just as easy to forget.
On your phone:
- Swipe down to open Quick Settings and look for Do Not Disturb (crescent moon icon) or Focus mode. Switch it off.
- On iPhone, open Settings > Focus and check that no Focus mode (Do Not Disturb, Work, Sleep) is currently active. Check the schedule too — a Sleep focus scheduled overnight will swallow morning alerts.
- Check that the Gmail app is not excluded from any Focus mode’s allowed apps list.
On Windows:
- Open Settings > System > Notifications and switch Do not disturb off.
- Click Turn on do not disturb automatically and review the automatic rules — Windows can schedule quiet hours on its own.
A phone in Do Not Disturb mode will still receive the emails; it just will not tell you about them until you open the app. If your alerts always arrive in one big batch when you unlock the phone, Do Not Disturb is the prime suspect.
5. Check the Gmail app’s own notification level on your phone
The Gmail app has per-account notification levels that are separate from your phone’s system permission. Many people enable the system permission but leave the in-app level on High priority only or None, and then wonder why most emails arrive silently.
On Android:
- Open the Gmail app, tap the menu icon (top left), then Settings.
- Tap General settings, then Manage notifications, and make sure All Gmail notifications is on.
- Go back, tap the account you care about, then tap Notifications and choose All — not High priority only, not None.
- Under Inbox notifications, pick the behaviour you want, and check Manage labels if you want alerts for specific labels.
On iPhone or iPad:
- Open the Gmail app, tap the menu icon, then Settings.
- Tap your account, and under Notifications tap Email notifications.
- Select All new emails.
- Also check your iPhone’s Settings > Notifications > Gmail and make sure Allow Notifications is on with Lock Screen, Notification Center, and Banners ticked.
If you use multiple accounts in the Gmail app, repeat these steps for each account. Google’s official Android notification help page also walks through these in-app levels and reminds you that device settings and app settings are separate layers. If you find our guides useful, you can read more about what we do on our About page.
6. Make sure Gmail sync is on and battery optimisation is not killing it
If your phone gets alerts late — or only when you open the app — the problem is usually not permissions at all. It is sync. Your phone’s power-saving system stops Gmail from checking for new mail in the background to save battery, so there is nothing new to notify you about.
- In the Gmail app, go to Settings, tap your account, and make sure Sync Gmail is ticked. Google’s own troubleshooting steps for missing Android notifications list this as the key check.
- On Android, open Settings > Apps > Gmail > Battery (wording varies by manufacturer) and set battery usage to Unrestricted or turn off Optimise battery usage for Gmail. Do not set it to “Restricted” or “Optimised” if you want timely alerts.
- Switch off Data Saver for Gmail, or add Gmail to the unrestricted data list, so background data is not blocked.
- Make sure Background data and Auto-sync data are enabled in your device’s account settings.
- On iPhone, check Settings > General > Background App Refresh and make sure it is on for Gmail.
This fix is especially common on Samsung and other phones with aggressive power management, where the default battery policy quietly throttles background apps. The good news: once sync is healthy, alerts usually return immediately.
7. Rule out extensions, closed tabs and signed-in sessions
When the permission chain is correct but alerts still misbehave, look at what else is running:
- Disable ad-blockers and privacy extensions one by one. Some extensions block notification pop-ups or the scripts that trigger them. Disable them all, test Gmail alerts, then re-enable them one at a time to find the culprit.
- Keep exactly one Gmail tab open. Multiple Gmail tabs or windows in different profiles can confuse desktop notifications.
- Check for a stuck session. If you are signed in to Gmail on several browsers or devices, sign out everywhere (Gmail settings > Manage your Google Account > Security > Your devices) and sign back in on the one you use.
- Confirm you are not in an incognito or private window. Private windows typically block notification permissions by default.
- Try a different browser. If alerts work in Edge but not Chrome, the problem is Chrome-specific settings or extensions, not Gmail.
Work through these one at a time and test with a quick email to yourself after each change. Sending a test message from another account is the fastest way to confirm whether a fix worked.
8. Still stuck with Gmail notifications not working? Update, clear site data, or reinstall
If nothing above has worked, the software itself may be at fault — an outdated app, corrupted site data, or a broken install.
On desktop:
- Update your browser to the latest version. Browser updates sometimes reset permissions, so re-check Fix 2 afterwards.
- Clear Gmail’s site data: in Chrome, go to Settings > Privacy and security > Site settings > View permissions and data stored across sites, find mail.google.com, and clear its data. Then re-allow notifications when Gmail asks.
- As a last resort, reset the browser’s notification settings to default and set them up again from Fix 2.
On mobile:
- Update the Gmail app from the Play Store or App Store.
- If the app still misbehaves, clear its cache (Settings > Apps > Gmail > Storage > Clear cache on Android). Do not clear data unless you are comfortable re-signing in.
- Reinstall the Gmail app as the final step. Your emails live on Google’s servers, so nothing is lost — you just sign back in.
Only download Gmail from the official Play Store or App Store, and only update your browser through its built-in updater. Third-party “Gmail fix” tools and unofficial app downloads are a malware risk and never necessary for this problem.
What to avoid
- Do not download “Gmail notifier” utilities from random websites. Unofficial tools can steal your login details. Gmail’s built-in notifications are all you need.
- Do not use activators, cracks, or “driver updater” downloads while troubleshooting. They will not fix notifications and they put your system at risk.
- Do not clear all browser data as a first step. Clearing cookies and site data for every site signs you out of everything. Target Gmail’s site data only, as described in Fix 8.
- Do not turn off every notification on your phone to “start fresh”. You will create more problems than you solve. Fix one layer at a time.
- Do not ignore the Save Changes button in Gmail’s desktop settings. The setting does not apply until you save it.
- Do not assume one device’s settings cover all devices. Phone, laptop, and tablet each need their own permission chain.
FAQ
Why did my Gmail notifications stop working suddenly?
The most common causes of a sudden stop are a browser update resetting site permissions, Do Not Disturb being switched on by accident, a new extension blocking pop-ups, or a phone software update re-enabling battery optimisation for Gmail. Work through Fixes 2, 4, 6, and 7 in that order.
Why do I get Gmail notifications on my phone but not on my computer?
Desktop and mobile alerts use separate permission chains. Your phone has its own settings, while your PC needs Gmail’s desktop notification switch on (Fix 1), the browser permission allowed (Fix 2), and Windows notification banners enabled (Fix 3). Check all three on the computer.
Why do Gmail notifications arrive late?
Late alerts are almost always a sync problem. Battery optimisation or Data Saver is stopping Gmail from checking for new mail in the background, so the notification only fires when you open the app. See Fix 6 for the exact settings to change.
Do I need the Gmail app open for notifications to work?
On desktop, yes — the Gmail tab must be open in the browser for desktop notifications to appear. On a phone, the app does not need to be open, but background sync and background data must be allowed, otherwise alerts only arrive when you launch the app.
Why am I not getting notifications for all my emails?
If only some emails trigger alerts, check for filtering. In Gmail’s settings, you may have Important mail notifications selected instead of New mail notifications. In the mobile app, the notification level may be set to High priority only. Also check that the emails are landing in your Primary inbox category rather than Promotions or Social, and that you have configured the right account if you use several.
Can I customise the Gmail notification sound?
Yes. On desktop, go to See all settings > General > Desktop notifications and pick a sound next to Mail notification sounds, then save. In the mobile app, go to Settings > your account > Notifications > Notification sounds. Your phone’s own sound and volume settings also apply.
Conclusion
When Gmail notifications are not working, the fix is nearly always one of three things: Gmail’s own notification switch is off, the browser or phone has not been given permission to show alerts, or Do Not Disturb is quietly swallowing them. Start with the quick checks, then work through the 8 fixes in order — most readers will have their alerts back by Fix 4.
