How to Fix WordPress Not Sending Emails

Why Is My WordPress Site Not Sending Emails?

The most common cause of WordPress emails not sending is that your hosting server needs to be configured correctly to use the PHP mail() function. Even if your hosting is set up to use it, many email service providers, such as Gmail, employ various tools to reduce email spam. These tools attempt to determine whether an email is truly coming from the address it claims to be from.

Emails from WordPress websites frequently fail this test. This means that when you send an email from your WordPress site (for example, contact form plugin, admin notification, etc.), it may not even make it to the recipient's spam folder, let alone their inbox. As a result, we do not recommend using WordPress to send your email newsletter.

Another alternative to sending email newsletters is through dedicated email marketing platforms. Please see our article on how to start email marketing the easy way to get started.



How to Fix WordPress Email Deliverability Problem

To troubleshoot WordPress email deliverability issues, we recommend using SMTP when sending to prevent WordPress emails from going to spam.

What Is SMTP

Simple Mail Transfer Protocol (SMTP) is the industry standard for email transmission. In contrast to the PHP mail() function, SMTP employs proper authentication, resulting in high email deliverability. Moreover, SMTP offers more features like email tracking and reporting, bounce handling, and automatic retries for failed deliveries.

The WP Mail SMTP plugin for WordPress configures your WordPress site to send professional emails via SMTP rather than the PHP mail() function. It can connect to any popular SMTP service, such as Gmail (G Suite), Microsoft 365, Amazon SES, etc.

With that said, let's look at how to resolve the WordPress not sending email problem.

WP Mail SMTP Plugin Installation

We recommend using the WP Mail Plugin to fix WordPress emails that are not sending. Follow these steps:

  1. Install and then activate the WP Mail SMTP plugin. Please see our step-by-step guide to installing a WordPress plugin for more information.

  4. To use WP Mail SMTP, first enter your SMTP settings. The steps will be the same regardless of your hosting provider. It has the following options:
    • From Email - This is the email address to which all WordPress emails will be sent.
    • This name will be used to send emails -We suggest that you use the title of your website as the form name.
    • Mailer - Choose Other SMTP here because you will send emails through your host's SMTP server.
    • Return Path - Select this option to receive delivery notifications or bounced messages.
  5. To keep using your host, select Other SMTP and enter the SMTP server settings given by your hosting provider.
    • SMTP Host - The SMTP host address given by your hosting provider.
    • Encryption - The encryption method used by your mail server to send emails. TLS is usually used.
    • The outgoing mail server uses the SMTP port.
    • Auto TLS - This option should be enabled.
    • Authentication - This must be set to On.
    • SMTP Username - This is the email address you use to send emails.
    • SMTP Password - Your email account password from which you send emails. We don't think you should save SMTP passwords in this location. Instead, keep your password in the wp-config.php file.

Updating these settings is required to connect to any SMTP server. Their values, however, may differ from one WordPress hosting company to the next.

Let's look at configuring the WP Mail SMTP plugin with Bluehost.
