It&#8217;s a common issue many WordPress users face, but it can be annoying when your carefully crafted newsletters don&#8217;t reach your audience.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fortunately, fixing this problem is easier than you might think. In this tutorial, we&#8217;ll show you three easy steps to resolve the issue using the Post SMTP plugin.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By following this article, you can reliably send emails to your audience so that they stay updated and engaged.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ready? Let&#8217;s begin!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why Is The Newsletter Plugin Not Sending Emails?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding the root cause of why the Newsletter Plugin isn&#8217;t sending emails is extremely important. There are a couple of common reasons why this problem occurs, and we&#8217;ll explain them below.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Reason #1: WordPress Default PHP Mail Function<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The primary reason why the Newsletter Plugin might not be sending emails is due to the default mail function used by WordPress, known as wp_mail. This function relies on PHP&#8217;s built-in mail function (wp_mail), which is not the industry standard for sending emails.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As a result, emails aren&#8217;t sent or end up in spam folders because they don\u2019t include proper <a href=\"https:\/\/postmansmtp.com\/email-domain-authentication\/\" target=\"_blank\" rel=\"noreferrer noopener\">email domain authentication<\/a>. This issue is particularly prevalent when using shared hosting or hosting environments that don&#8217;t provide robust email sending capabilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, it&#8217;s essential to use an SMTP (Simple Mail Transfer Protocol) server that provides the necessary authentication to ensure that your emails are delivered reliably.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>PLEASE NOTE:<\/strong> Earlier versions of the Newsletter plugin had SMTP as a feature; however, now you need to set up SMTP using a separate plugin such as Post SMTP. Also, we don\u2019t recommend using any SMTP addon for the Newsletter plugin, which we\u2019ve explained in detail in the second reason in detail.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"1114\" height=\"227\" src=\"https:\/\/postmansmtp.com\/wp-content\/uploads\/2024\/08\/Newsletter-plugin.jpg\" alt=\"Screenshot of a WordPress newsletter plugin interface, showing email campaign setup options and customization tools.\" class=\"wp-image-89861\" srcset=\"https:\/\/postmansmtp.com\/wp-content\/uploads\/2024\/08\/Newsletter-plugin.jpg 1114w, https:\/\/postmansmtp.com\/wp-content\/uploads\/2024\/08\/Newsletter-plugin-300x61.jpg 300w, https:\/\/postmansmtp.com\/wp-content\/uploads\/2024\/08\/Newsletter-plugin-1024x209.jpg 1024w, https:\/\/postmansmtp.com\/wp-content\/uploads\/2024\/08\/Newsletter-plugin-768x156.jpg 768w\" sizes=\"(max-width: 1114px) 100vw, 1114px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Reason #2: Multiple SMTP Conflict<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you have multiple plugins or SMTP settings configured to handle email delivery, they might interfere with each other, causing email delivery failure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For instance, if one plugin is set up to use a specific <a href=\"https:\/\/postmansmtp.com\/free-smtp-server\/\" target=\"_blank\" rel=\"noreferrer noopener\">SMTP server<\/a> while another is configured to use a different one, this can create a conflict that prevents emails from being sent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Conflicting SMTP settings can lead to various issues, including emails not being sent, being sent with incorrect headers, or even being blocked by email servers due to improper configurations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To avoid this, it&#8217;s important to ensure that only one SMTP server is handling all email deliveries from your WordPress site. This will eliminate any conflicts and ensure that your Newsletter Plugin can send emails without any issues.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>3 Easy Steps to Fix The Newsletter Plugin Not Sending Emails<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Now that we&#8217;ve identified the possible causes, let&#8217;s dive into the solution. We&#8217;ll be using the Post SMTP plugin to fix the issue, as it provides a reliable way to send authenticated emails through your chosen SMTP server.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Follow the steps below to fix the Newsletter plugin not sending emails.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step #1: <\/strong><strong>Install and Activate Post SMTP Plugin<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The first step is to install and activate the Post SMTP plugin on your WordPress site.
