Fixes for Gmail Not Sending Emails Issue

Have you done the basic troubleshooting but still find Gmail receiving but not sending emails? Then here are some advanced measures you should implement.

1. Check the Storage Space and Know About the Items that Take Up the Most Space

One of the primary causes of this issue is insufficient storage space. If your storage space is over 90 percent, you cannot send emails from Gmail. You can easily check the storage space of your Google account by scrolling to the bottom-left part. When you click on ‘Manage,’ you will find more details of the storage space left. 

Apart from that, you must also know the items that use the most space. They include PDFs, images, videos, and items in your trash. Items in several folders get synced to folders in your system and take up more space.

2. Check Your Email Sending Limit

Many of those who complain that their Gmail stopped sending emails aren’t aware of the per-day limit of sending messages from Gmail. Although the sending limit is very high if you exceed it can also result in you not being able to send emails.

You can send 2000 messages per day. To learn more about the sending limit here. Ensure that you do not go over it. 

3. Look for Spam in the Email Body

If your email contains any kind of spam in its body part, it will not get sent to the recipient. An example of spam in the email body is linked to non-credible websites. Besides this, if you input a huge number of email addresses in Bcc or CC fields, you’ll find it difficult to send emails. 

4. Eliminate Viruses on Your System

Sometimes, a virus on your system will not let you send emails. Modern-day viruses can likely cause Gmail not to send email issues. If you find the below symptoms on the device, it means that your system is in the grips of a virus. 

• Your device is showing many ads. 
• Your device has become very slow. 
• Or, your browser’s homepage looks different.
• Various programs don’t begin on your device

Fortunately, you can remove the virus with the help of Windows Defender, the in-built antivirus program in Windows.

• In the search box, input ‘virus & threat detection.
• Tap ‘Scan options.’
• Choose the ‘Full scan.’
• Now, tap ‘Scan now.’
• Adhere to the instructions onscreen. 

5. Remove Browser Cache and Cookies

The browser keeps cookies of every site you visit. It results in a good website browsing experience, and you get to see results and queries related to what you search about the cookies. But excessive cache and history can result in Gmail not sending emails. So, it’s best to clear them from time to time. You can easily clear your browser cache and cookies by going to the settings. 

6. Configure Client-Server Email Settings

To configure the email client, follow these points.

• Firstly, tap Gmail settings.
• Now click the tab ‘Forwarding and POP/IMAP.’
