To ensure your emails are promptly sent from Gmail on both your mobile device and desktop, it’s crucial to troubleshoot any issues causing them to be stuck in the outbox. Follow our comprehensive guide to resolve these concerns efficiently.

Check Your Phone or Desktop’s Internet Connection

If you find your emails stranded in Gmail’s Outbox, start by verifying the internet connection on your desktop, iPhone, or Android phone. A stable connection is essential for Gmail to send or receive emails successfully.

  • Launch a web browser and open a site to confirm your internet connection.
  • Restart your Windows PC, Mac, iPhone, or Android device to resolve connectivity issues.
  • If using Wi-Fi, ensure you are connected to an active network.
  • If the problem persists, reboot your modem and router. If the network is still down, contact your Internet Service Provider for assistance.

Turn Off Gmail’s Offline Mode on Desktop

For desktop users encountering email issues, it’s crucial to check and disable Gmail’s offline mode. This feature may be holding your emails in the Outbox until it’s turned off.

  1. Open in your web browser.
  2. Sign in, click the gear icon in the top-right, and select “See All Settings.”
  3. Navigate to the “Offline” tab and disable “Enable Offline Mail.”
  4. Save changes and reload the Gmail site in your browser.

Refresh Gmail’s Outbox Folder on Your iPhone or Android Phone

Force Gmail to send pending emails by refreshing the Outbox folder on your mobile device.

  1. Launch the Gmail app and tap the hamburger menu (three horizontal lines).

2. Select “Outbox.”

3. Pull down from the top within the Outbox folder to refresh and send pending emails.

Clear Gmail’s App Cache on Android

If issues persist, corrupted cached files in the Gmail app may be the culprit.

  1. On your Android phone, go to Settings > Apps > Gmail > Storage.
  2. Tap “Clear Cache.”

3. Close Settings and relaunch the Gmail app.

Update Gmail on Your iPhone or Android Phone

Outdated Gmail apps can introduce bugs, hindering your ability to send emails. Ensure you have the latest version installed.

  • On Android, go to Google Play Store, find “Gmail,” and tap “Update.”
  • On iPhone, open the App Store, navigate to “Updates,” and choose “Update” next to “Gmail.”


By addressing internet connectivity, disabling offline mode, refreshing the Outbox, clearing app cache, and updating the Gmail app, you can resolve issues with stuck emails in Gmail. Follow these steps to ensure a smooth email-sending experience on both desktop and mobile devices.
