Why Do My Emails Fail to Send? Quick Solution

Are you facing the issue of email-delivery while working with WordPress?

It is one of the most common problems that many bloggers and digital marketers usually face. This is especially troublesome if you often send emails to communicate with the customers of your eCommerce website.

If you’re one of those WordPress users facing this issue, then don’t worry, we have a solution here.

In this article, I’ll discuss an awesome WordPress plugin i.e. WP Mail SMTP Pro by WPForms that will help you to fix email related issues.

What is SMTP?

SMTP is the main reason behind the failed email-delivery. The term SMTP stands for Simple Mail Transfer Protocol which is used to send emails across servers.

To ensure the email delivered successfully, you need to configure SMTP properly. If there is an authentication error, your emails can either go to the spam folder or fail to deliver.

Most Common Reasons When WordPress fails to Send Emails

The main reason behind the email sending failure is that WordPress uses the default PHP mail function to send emails by default. However several hosting servers are not configured to use this mail() function.

In general, when you choose a cheap hosting provider, it may not include email services in your pack. That’s why I recommend using a good web hosting provider for your WordPress website.

Most of the hosting services use various tools to reduce the number of email spam. These tools generally detect the email origin and its location.

And WordPress fails to send out an email. It put the email into the spam folder or even denies sending as well. That’s why you should consider SMTP to send emails from WordPress.
