Gmail not receiving emails? It’s frustrating, especially when you’re waiting for something important. If your inbox seems unusually quiet, it might not just be a slow day.
There are several common reasons why Gmail might stop receiving messages, like storage issues, filters, syncing problems, or even a misconfigured setting.
The good news? Most of these issues are easy to fix once you know where to look.
In this guide, we’ll walk you through the top reasons Gmail isn’t receiving emails and show you step-by-step solutions to get your inbox back on track, fast.
Let’s find the issue and fix it so you never miss an email again.
Common Reasons Gmail Is Not Receiving Emails
Here are the common reasons why Gmail is not receiving emails:
Gmail Storage Is Full
Google gives you 15 GB of free storage shared across Gmail, Google Drive, and Google Photos. When this space fills up, Gmail silently stops receiving new emails—no alerts, no warning.
Your inbox won’t receive messages, and senders may get bounce-back notices. This is one of the most common and overlooked reasons Gmail goes quiet.
If you’ve been using Gmail for years, or share your Google account with work documents or cloud backups, check your storage level immediately. Go to Google One storage manager to view usage by service.
Filters or Tabs Are Redirecting Emails
Sometimes Gmail is receiving your emails—but they’re being automatically moved out of your Primary inbox. Filters and Gmail’s built-in category tabs can route messages to Updates, Promotions, or Social without notifying you.
If you’ve created custom filters to organize messages or used tools from our email management tips check that they aren’t archiving or skipping the inbox unintentionally.
Also, review your Gmail filters under Settings > Filters and Blocked Addresses. Filters with “Skip the Inbox” or “Apply the label” can cause you to miss emails if misconfigured.
Messages Sent to Spam Folder
Gmail’s spam filter is strong—but sometimes, it gets it wrong. Important messages from new contacts, email subscriptions, or automated systems can land in Spam, especially if Gmail detects unusual content or sender behavior.
Go to the Spam folder on the left sidebar of Gmail and look for any messages that don’t belong there. If you find something legitimate, mark it as “Not Spam.” This helps train Gmail to avoid future misplacement.

Senders Blocked or Marked as Spam
If you’ve previously blocked a sender—intentionally or by accident—Gmail will never deliver their messages to your inbox. Blocked addresses can be managed through the same settings menu as filters.
Navigate to Settings > Filters and Blocked Addresses. Scroll down to the Blocked list. Unblock any addresses you recognize or want to start receiving messages from again.
Be cautious when mass-deleting emails with similar names—some Gmail users have unknowingly blocked colleagues, clients, or services due to fast clicks during cleanups.
Sync Issues with Devices or Apps
If Gmail appears empty or outdated on your phone or computer but works on another device, it’s likely a sync issue. This could be caused by:
- App permissions being disabled
- Network connection problems
- Outdated app versions
- IMAP/POP server disruptions (for third-party apps)
Try refreshing your Gmail app or web browser. On mobile, go to device settings > Apps > Gmail > Permissions and make sure everything is enabled.
You can also check account sync under your device’s “Accounts” section. For power users managing multiple inboxes, using advanced email hacks can help simplify sync settings across platforms.
DNS or Custom Domain Errors (For Gmail with Custom Email)
If you use Gmail through Google Workspace (formerly G Suite) with a custom domain (like yourname@yourbusiness.com), DNS errors could be blocking mail delivery.
You’ll need to:
- Check that your MX records point to Google servers.
- Log into your domain registrar and verify DNS setup.
- Confirm routing rules in the Google Admin Console.
Mistakes here can cause incoming mail to bounce or be routed to the wrong destination. Google’s admin tools provide diagnostics and step-by-step DNS setup instructions via the Google Support guide (do-follow link).
Step-by-Step Solutions to Fix Gmail Not Receiving Emails
Here are step-by-step solutions if your Gmail isn’t receiving emails:
1. Check Gmail Storage Limits
First, make sure your account isn’t out of storage. If your 15 GB Google account storage is full, Gmail will stop receiving new emails. Here’s how to fix it:
- Visit Google One storage page to see how your space is used.
- Empty your Gmail trash and spam folders.
- Delete large emails or use the search query has:attachment larger:10M to find big files.
- Remove old Drive files and photos you no longer need.
Regular maintenance using our management tips will help you keep space free and your email flowing smoothly.
2. Review Gmail Filters and Tabs
Filters are great when used right, but a single misstep can send messages into labels you never check. Here’s how to review and fix them:
- In Gmail, go to Settings > See all settings > Filters and Blocked Addresses.
- Review any filters with “Skip the Inbox” or “Delete it” actions.
- Edit or delete filters that might be wrongly handling incoming mail.
Next, check your Gmail categories. Gmail sorts mail into Primary, Social, Promotions, Updates, and Forums tabs. Sometimes, important messages go straight to Promotions or Updates, especially from new senders or businesses.
Click each tab and scan for recent messages. Drag any misplaced email to the Primary tab, and Gmail will learn to deliver similar emails there in the future.
3. Inspect the Gmail Spam Filter
Gmail’s spam detection system automatically moves suspicious emails to the Spam folder. But sometimes, important messages are mistakenly marked as spam.
To fix:
- Go to your Spam folder in Gmail’s left sidebar.
- Look for messages from expected senders.
- Select any safe message and click “Not Spam.”
Doing this also tells Gmail to whitelist the sender, improving future deliverability.
Explore the Gmail spam filter guide to understand how it flags messages and how you can control it more effectively.
4. Check for Blocked Senders
Blocked senders are automatically filtered out of your inbox. You may not even realize you’ve blocked someone until you stop receiving their messages.
To manage blocked contacts:
- Go to Settings > Filters and Blocked Addresses.
- Scroll to the list of blocked addresses.
- Click “Unblock” next to any sender you want to allow again.
Review this list regularly—especially if you’re not getting messages from someone you expect.
5. Fix Gmail Sync Issues
If Gmail is working on one device but not another, it’s probably a sync issue. Here’s how to troubleshoot it:
On Mobile:
- Open Settings > Accounts > Google > Sync Gmail.
- Make sure “Sync Gmail” is turned on.
- Go to the Gmail app > Settings > Your account > Sync settings and verify everything is active.
- Clear app cache if needed, or reinstall the Gmail app.
On Desktop:
- Reload Gmail in your browser.
- Try accessing Gmail in Incognito or another browser to rule out extensions.
- Disable email clients using POP/IMAP temporarily to isolate syncing problems.
Use mobile-optimized email hacks to reduce sync overload—like batching replies or using desktop shortcuts.
6. Confirm DNS and Email Forwarding (For G Suite Users)
For business email using Google Workspace, email routing problems can be more complex. If your custom domain isn’t receiving messages, check these steps:
- Verify MX records: Go to your domain registrar and ensure MX entries point to Google’s mail servers (e.g., ASPMX.L.GOOGLE.COM).
- Use Google Admin Console: Log in and review routing, aliases, or security rules.
- Disable conflicting email forwarders: Especially those outside the Google system, which might interfere with Gmail delivery.
Google Workspace includes diagnostic tools that alert you when MX records are misconfigured. Follow their official support guide for detailed steps.
Final Tips to Keep Gmail Running Smoothly
Prevent future problems by developing consistent email habits. Use automation wisely, check tabs and spam weekly, and avoid inbox clutter that masks serious issues.

The more proactive you are, the less likely Gmail is to misbehave, and the faster you’ll catch problems if they arise.
