Fix: Gmail Not Sending Email (Queued in Outbox)

The issue with Gmail not sending emails isn’t something you’ll come across often, but it’s still a headache when an important email that needs to be sent gets stuck at the wrong time. The emails get queued up in the outbox and are not sent until you fix the problem.

Now, one workaround that can work is that you should refresh your Outbox and see if the queued emails show the ‘sending’ status. If it does, then your email will be sent in a moment.

If this doesn’t work, then there will be some other reasons why your Gmail app isn’t working. Make sure your internet connection isn’t weak and no antivirus is blocking the app.

What should I do to get Gmail to send my emails again?

Below will be 4 tried and tested methods to solve this issue, but before that, check Gmail’s status and see if there’s a service disruption or outage. If there is, then it won’t function until Google actually solves the problem on its end. In such cases, you can only wait and hope the service will be up and running soon.

1. Clear App Cache and Data: Too much cache is not helpful for any app, and the same is the case with Gmail. There’s a big chance that this is the reason why your emails are stuck in the outbox, so clearing both the cache and the data will remove any bugs that were the reason for this problem. Also, clearing data doesn’t remove anything from your account, and you won’t lose any of your emails, so there’s no need to worry.
2. Unsync and Sync Gmail Again: The sync function can stop working sometimes in Gmail, so simply restarting it will send your emails queued up in the outbox.
3. Enable Background Data for Gmail: Enabling this lets Gmail use mobile data to refresh itself in the background if the app is not active. If you used mobile data to send the emails and closed the app with background data disabled, the emails will be stuck in the outbox. So, make sure this option is enabled.
4. Use Gmail in Browser: If there are still some problems with your app, then use Gmail in any browser in the meantime. Moreover, you can also try updating the Gmail app.

1. Clear the App Cache and Data

1. Go to Settings > Apps.

2. Select Manage Apps.

3. Search for Gmail and click on it.
4. Select Clear Data.

5. Select Clear Cache.

6. Open Gmail again and refresh your outbox.

If the emails are still not sent, then do the following:

1. Follow the first two steps.
2. Select Clear Data and select Clear All Data.

3. Now log in to your Gmail account again and see if the emails have been sent from the outbox.

Note: The settings can vary on your mobile device.

2. Un-sync and Sync Gmail Again

1. Open Gmail and click on the hamburger menu on the top-left.
2. Scroll down and click on Settings.

3. Select your Gmail account.

4. Scroll down to the Data Usage section.

5. Uncheck the Sync Gmail option and select OK.
6. Close the Gmail app.
7. Now reopen Gmail and repeat steps 1-4.
8. Checkmark Sync Gmail again and check your outbox.

3. Enable Background Data for Gmail

1. Go to Settings > App.
2. Search and select Gmail.
3. Tap on Data Usage.

4. Turn on the Background Data option.

Again, the settings can be different on your device.

4. Use Gmail in Browser

1. Open any browser on your PC or laptop and go to Gmail.com.
2. Login to your account.
3. Tap on Outbox and resend the emails.
