Gmail app messages aren't syncing

If Gmail isn’t syncing automatically, you might notice the following problems:

• Can't send mail, or mail is stuck in send
• Not receiving or not loading new mail
• Can't open or read mail
• Inbox not updating
• “Account not synced” error
• Not receiving notifications for new messages
• App is very slow

If you’re having notifications issues, check your Gmail notifications settings.

First, try these common fixes

Usually, one of the checks below helps solve the problem. 

Check that you’re connected to the Internet

Your internet connection might not be working. To check that you’re connected, try visiting a website in your mobile web browser. If you’re using public Wi-Fi, like at a cafe or library, you might need to load a website to accept the Terms & Conditions before you’re actually connected. 

Also, make sure Airplane Mode is turned off.

Turn on background app refresh

1. Open your device settings. 
2. Scroll down  tap Gmail .
3. Turn on Background app refresh. 

Check sync settings on your Gmail app

Depending on your sync settings, the Gmail app checks for new mail every 1 to 30 days.

1. Open the Gmail app .
2. At the top left, tap Menu Settings .
3. Under "General," tap Data Usage Sync settings.
4. Select the number of days you want to sync.

Check your storage space 

Your storage is shared across Google Drive, Gmail, and Google Photos. To see how much space you have left, go to www.google.com/settings/storage on a computer.

Issues specific to non-Gmail addresses

If you use the Gmail app with a non-Gmail address, like @yahoo.com or @hotmail.com, check your email on a computer to check if the sync issues you were experiencing, like not seeing any new mail, are only occurring in the Gmail app.

If you’re not able to view new mail on the computer, check the support information for your email provider.
