Arguably, Gmail is the most popular email client in the world. As a service, it is a pretty solid option. However, many users say that they experience various issues quite often with the Gmail app on Android.

Reasons for “Gmail Not Sending Emails” Issue

Before diving into the troubleshooting steps, let’s explore some common causes behind the issue of Gmail not sending emails on your smart phone.

Network Connection Issues

One of the primary reasons why you may be unable to send emails through Gmail is a weak or unstable network connection. If your device doesn’t have a stable internet connection, it won’t be able to communicate with Gmail’s servers effectively.

Incorrect SMTP Settings

SMTP (Simple Mail Transfer Protocol) settings are responsible for the outgoing email functionality of your Gmail account. If these settings are misconfigured or outdated, you may encounter issues when sending emails from your smart phone.

Gmail App Configuration

Sometimes, the problem lies within the Gmail app itself. It could be due to a misconfiguration or a glitch that is preventing the app from sending emails. Troubleshooting the app settings can often resolve this type of issue.

Method 1: Check if the Details of the Email Recipient Are Correct

One of the most basic things you should check when Gmail not sending emails is the respective address. Although this sounds like a no-brainer, a surprising number of individuals enter the email address with errors.

As a result, the respective email will not be sent. You may already know that even a single error on the address will prevent the email from being sent.

So, check if the recipient’s email has an extra dot, hyphen, letter, or anything else. Also, you should make sure if anything is missing from the recipient’s email address. The key is to enter the email address correctly without any mistakes. So, be sure to double-check what you type as the email address.

If you are 100% sure about the correctness of the email address, your email should simply work. But if Gmail not sending emails, even if you type the correct address, try the solutions listed below.

Method 2: Check if the Gmail Server Is Configured Correctly

You might be using other email accounts other than Gmail on your device to communicate with others. If that applies to your situation, you should ensure that you are properly signed in using the credentials.

In addition to that, you must ensure that POP/SMTP Servers are configured with the correct ports. Just go through with those configurations and check if everything is in order. You can do a bit of research on configuring a third-party account on your Gmail client.

Method 3: Clear the Cache and Data on Your Gmail

Every Android app installed on your device uses a local cache and data to function. Cache becomes useful to provide a better user experience. Also, cache helps you experience a better user experience. The cache, however, can build gradually into a huge file, and the data in it can get corrupted. When those files get corrupted, the app will start to malfunction.

So, when the cache is left unattended for a pretty long period, it can do more harm than good. For instance, the app will perform slowly and may even fail to perform some intended tasks. The same theory applies to your Gmail app, as well. We strongly recommend you clear the cache and data on your apps, at least on an occasional basis.

You Can Follow the Steps Below and Clear Cache and Data on Your Gmail App.

  • First, you should open the “Settings” app on your Android device.
  • Then, under “Settings“, choose the option called “Apps“.
  • After that, please open the “App Manager” and choose “All Apps“. Please note that on some phones, this option might appear as “Manage Apps” as well.
  • Since we want to clear the cache of Gmail, choose the “Gmail” app to proceed.
  • Now, you will see an option labeled “Storage“. Just tap on it.
  • Clear the Cache first. Then, you should clear the option called “Clear Data” as well.

  • After that, you can reboot the Android device and launch the Gmail app. Then, you can test if the Gmail app sends emails working as usual.

If you cannot overcome the issue even after clearing cache and data, try this method. As per this method, you should uninstall the Gmail app on your Android device and install it again.

However, in some OEMs, you will not be able to uninstall Gmail. That is because they have made Gmail a system app. In that case, you can just uninstall the updates, so new updates will be installed.

When you do this, your Gmail account and other services offered by Google will be reset. This is not a complex process at all. Also, you don’t have to worry about the process because your data is saved in the cloud.
