First let’s understand why Emails are likely to get blocked when sent directly thorough WordPress? Why WordPress Email deliverability isn’t reliable?

The built-in configuration in WordPress uses PHP (Hypertext Preprocessor) mail function to send emails. And most of the times the web hosting companies don’t have their PHP email configurations properly set. This way the emails that are sent are not properly optimized and authenticated. Hence they get either blocked or spammed. Popular email services such as Gmail, Outlook Mail and Yahoo Mail don’t really entertain such emails. As a result they are simply blocked or moved to spam folder.

Most of the popular email service providers expect the emails to be sent via SMTP (Simple Mail Transfer protocol) which is a standard protocol to send and receive Emails. That means that you would have to re-configure WordPress email function to use standard SMTP protocol and use SMTP host credentials of your web host.

Emails not delivered or blocked is a more annoying thing for those who are running E-Commerce websites, because such websites need to send a lot of auto responding emails such as user registration confirmation, email notifications, password verification, order confirmation and more.

So What’s the solution?

The solution is pretty much simple you will have to make WordPress re-configure email function in order to use standard SMTP protocol. How would you do this? Again the answer is simple: You would need a SMTP plugin to harness WordPress email system.

So which is the best SMTP plugin for WordPress?

My sincere recommendation would be to use WP Mail SMTP Plugin by WPForms. The free version itself is sufficient to setup popular email services. They do offer premium features with more facilities and extended support. Click on the image below to know more about WP Mail SMTP Pro:

First Step: How to find SMTP information in your hosting cpanel?

There are different ways to know the SMTP details but I am going to show you how to get these information from your hosting cpanel. As my website is hosted in (The Best and Cheap Web Hosting Service in India), I could show you how you could get these details from hostinger’s hpanel. Your cpanel should have similar options.

Login to your Hostinger’s Hpanel ⇒ click on Hosting ⇒ then click on Manage button of any of your domains ⇒ then scroll down and click on Email Accounts ⇒ Now you should be able to see your website’s Outgoing Mail (SMTP) Server details. Just note down the Host name and Port number. Please refer to the images below:

Second Step (optional): Creating a cpanel email (If have one already you could use its credentials)

As WP Mail SMTP plugin requires you to enter the email username and password, you should either enter the existing email credentials or create a new cpanel email and use its username and password credentials. So to create an email account using your cpanel follow these steps:

Form the Hostinger’s Hpanel ⇒ Go to Email Accounts ⇒ In the Create a New Email Account section type a name such as support or info or help etc and enter a password (these credentials are needed to set up WP Mail SMTP) ⇒ Then click on the create button. Please refer to the images below:
