Gmail as a service may be pretty solid, but the Gmail app for Android isn't everyone's cup of tea. Since Google discontinued Inbox, Gmail for Android has hardly been a worthy replacement. Especially if there are essential issues like Gmail Not Sending Emails. If you can't receive email through Gmail, see our post on that. On the other hand, if you can't send emails because they get stuck in your Outbox, follow the steps below.

How to fix Gmail not sending emails?

You can try the following steps in case you are unable to send Gmail emails.

First to check is that you are connected to the Internet.

Make sure you don't make typos when entering your recipient's email address.

Check the size of the file you are attaching. It must not be more than 25 MB.

Be sure to submit a supported file format.

You must also confirm that you are using a supported browser. Officially, the supported browsers for Gmail on a computer are Google Chrome, Firefox, Safari, and Microsoft Edge.

Javascript must be enabled in your browser.

Try sending the email once more after disabling all plugins and add-ons in your browser.

Please run your browser in incognito mode and send an email once more. See if this solves the problem.

If you still can't send Gmail messages, you may consider switching to another browser or device.
