This step can be a little tricky and sophisticated but you do not need to worry. Just follow the steps and see the screenshots, you will easily get through it.

First, you have to go to the Google Developers console. To create a new project, click on the “Google Review embedding” as marked by “1” in the screenshot below. However, if you are the first-time logging into the Google Developers Console, a prompt message will ask you to create a new project directly :

After creating a new project click on “Enable APIS and services”. which will prompt you on an API library.

Enable Apps And Services

In the API library search for “Gmail API” in the search box.

Add credentials to your Project

After answering the above three questions, click on the What credentials do I need? button. A prompt-up window will appear on which you have to select the “set up consent screen” option.

Note: All the information entered by you will be used only for your WordPress site.

This will open a new tab where you have to configure the OAuth consent screen. Keep all the previous tabs open, because you have to go back to them immediately.

In the User type section, check the “External” option as shown and click on the “Create” button.

Add Gmail API client ID and Client Secret

When you click on the “Save changes” button, the plugin will ask you to grant permission to google.

Grant Permission with Google

When you click on the grand permission link, Google will initiate a typical authorization process. During the process, it may show you a warning message, but you do not need to worry about it. It is because you have not submitted your app to Google for review, hence it will show you a warning message stating ” This app isn’t Verified“.

Since the app is for your website use only and not for the public domain, you can ignore that warning message by clicking on the “Advanced settings option and again click on the “xyz.com(unsafe)” link which completes the authorization process.

App verification warning message

After that everything will be regular but you have to ensure that you must select the Allow option that enabled your WordPress site to have access to your Gmail account. This permission will let you send emails through the Gmail SMTP server.

Now you are done, the only thing left is the testing part.

Step 4: Check Whether the Gmail SMTP Server Configuration Is Working

Once the setup is done, it is time to check whether the Gmail SMTP server configuration is working or not. Even the Post mailer plugin has the option to send a test mail. The only thing you have to do is to go to the WordPress dashboard and click on the Post SMTP tab.

Post SMTP Test Email

Enter the Recipient’s email address and click on the “Next” button. Then you should see a success message on the same plugin interface as shown in the picture below:

Screenshot 4 3 What Is A Gmail SMTP Server and How to Use It for Sending Emails for Free?

You can even cross-verify by checking your email inbox and there should be a test email received. If everything goes well, it means you have set up things correctly and you are done with Gmail SMTP server configuration.


Now from the above post, you have seen the Gmail SMTP server lets you send emails directly via your Google account and via secured Google servers. On top of that, you can also enable SMTP in Gmail, use the Gmail SMTP server with your domain, and even send emails through the WordPress site.
