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

When the send option in Gmail app suddenly becomes unavailable, it can be confusing—especially when you’re ready to send an important email.

The good news is that this is usually a minor issue caused by settings, connectivity, or the app itself. Below are some simple fixes you can try to bring the send button back and continue emailing normally.

Clear Gmail App Cache

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: Keeping the Gmail app updated is always a good idea. New updates often include bug fixes and improvements that can resolve issues with app features not working properly. Open the Google Play Store and check for any available Gmail updates.

Why Is My Gmail Send Button Greyed Out?

A common reason the Gmail send button gets greyed out on Android is a corrupted app cache. Gmail saves temporary files to improve performance, but these files can sometimes become outdated or stop working properly after updates or system changes.

When that happens, Gmail may fail to load certain options, including the send button. Clearing the app cache removes these broken temporary files without deleting your emails, allowing Gmail to create fresh data and work normally again.

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:

    Gmail limits the number of emails you can send within a certain period. If you send too many messages in a short time, Gmail may temporarily stop outgoing emails to protect your account from spam activity.

  • Attachment size is too large:

    Gmail allows attachments up to 25 MB. Files larger than this limit won’t send and need to be uploaded to Google Drive or shared using another file-sharing service.

    However, you don't need to worry about this as Gmail will automatically upload the file to Google Drive and share its link in the email body.

  • Too many recipients:

    Sending emails to a large number of people at once can trigger Gmail restrictions, especially if the activity looks unusual for your account.

  • Security checks or account restrictions:

    Gmail may temporarily block outgoing emails if it detects suspicious activity, unusual sign-ins, or anything that looks like a security risk.

  • Email stuck in Outbox:

    If the send button works but the message stays in Outbox, check your internet connection, account sync settings, and Gmail app status before trying again.

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 on Android is usually caused by a minor app issue, cache problem, or account restriction. Start by clearing the Gmail cache, checking your connection, and making sure your account hasn’t hit any sending limits.

If it still doesn’t work, update the Gmail app or re-add your account. In most cases, these simple fixes are enough to get your emails sending again.
