Want to deliver your WordPress emails using a SMTP server? We’ll show you how to use SMTP server to send your WordPress emails. WordPress uses PHP mail function to send emails about new user registrations, updates, comments, contact forms, password reset, etc. Due to the nature of PHP mail function, the originated emails are usually get into junk folder. Some popular email provider like gmail.com, yahoo.com aol.com, hotmail.com, would end up blocking the emails from your WordPress based site. In this tutorial, we will show you how to properly configure WordPress to send emails using SMTP. There are many plugins for doing this, but for now we are going to use Post SMTP plugin. There are some advantages we can take when using this plugin if compared to the other similar ones, like the ability to see email log, ability to export-import configuration, etc.

To use Gmail API, you first need to log into https://console.developers.google.com/start/api?id=gmail with the same email address that you are configuring Post SMTP with. There, you will be asked whether to use an existing project or create a new one, let’s create a new project instead.
In the next page, you will see that the API is enabled, let’s click on ‘Go to credentials’ to continue.

Which API are you using? Where will you be calling the API from? What data will you be accessing?
Let’s use GMAIL API, Web server (e.g. node.js, Tomcat), and User data as the answers.
Click on ‘What credentials do I need?’
In the next step, the consent screen page, you need to choose the email address you want to send emails from and fill the product name, click on continue. You will be brought to the final page, where you can see the Client ID and Client Secret.
Go back to your Post SMTP setting, and fill the Client ID and Client Secret you have.
Click on ‘Save Changes’
At this point, you will still need to allow your application (WordPress) to access your Gmail account.
After clicking on ‘Save Changes’ button, click on ‘Grant permissions with Google’ to continue.
Once you approved, your WordPress website is able to send emails using Gmail SMTP.
