Gmail Send Button Greyed Out on Android? Try This Quick Fixes

When you find Gmail send button not working (button that doesn't respond to taps), it can be really confusing—especially when you’re ready to send an important email.

The good news is that this is usually a minor issue that you can fix quickly. Below are some simple fixes you can try to bring the send button back and continue emailing normally.

How to Clear Cache On Gmail

I treat this fix as the gold standard for fixing greyed out 'Send' button in Gmail app. You can follow the steps below to clear the Gmail app cache.

  1. Long tap on the Gmail app, a popup will open. Tap the 'i' icon or 'App info' button.
Android App Info button
App Info button from the Gmail app.
  1. In Gmail app info, tap 'Storage' and then tap 'Clear cache.'
Clear Gmail app cache on Android from app settings
Tap Clear cache to delete temporary Gmail app files.
  1. Now go one step back and tap 'Force stop' to close the app.
  2. Go back to Android app drawer and tap Gmail app now. Open the draft email (previously saved) or create a new email.
  3. The Gmail 'Send' button will now work without any issues.

Expert Tip:Always ensure that your Gmail Android app is up to date. App updates come with bug fixes that prevent normal an app from working normally. To check for an update, simply open Google Play Store and search for the Gmail app. If an app update is available, you will see the 'Update' button. Just hit that button to install the latest app update.

Why Is My Gmail Send Button Greyed Out?

A greyed-out Gmail send button not working is often caused by a cache issue.

Gmail stores temporary files to help the app run faster, but these files can sometimes become corrupted after an update or system change. When that happens, certain features may stop working properly, including the Send button.

Clearing the Gmail cache removes these temporary files and lets the app create fresh ones. Your emails and account data won't be affected.

Gmail Limits Can Prevent Emails From Being Sent

Apart from a greyed-out Send button, Gmail may also stop you from sending emails when you hit certain account limits. These restrictions are usually temporary and can happen due to sending too many emails, large attachments, or unusual account activity.

  • Daily sending limit reached:

    Personal Gmail accounts can send up to 500 emails within a 24-hour period. If you hit that limit, Gmail may temporarily block outgoing messages.

  • Attachment size is too large:

    Gmail supports attachments up to 25 MB. However, larger files are usually uploaded to Google Drive automatically and shared through a link.

  • Too many recipients:

    Gmail also limits the number of recipients you can email within a 24-hour period. Sending to more than 500 recipients at once can trigger restrictions.

  • Security checks or account restrictions:

    Unusual sign-ins or suspicious activity can cause Gmail to temporarily block email sending. In such a case Google may ask you to verify your account ownership using account recovery options.

  • Email stuck in Outbox:

    If the Send button works but the email stays in Outbox, check your internet connection and account sync settings.

If Gmail still fails to send emails, the problem may be related to your internet connection. Before trying again, check whether your mobile data is working properly by following this guide to fix mobile internet issues on Android.

Conclusion

A greyed-out Gmail send button not working is usually linked to a cache problem, a Gmail sending limit, or a temporary account restriction.

Start by clearing the Gmail app cache, checking your connection, and making sure you haven't exceeded Gmail's limits. If the issue remains, update the Gmail app or add your account again on your phone.
