Whether it's to confirm a registration, receive form notifications or manage password resets, your emails need to arrive at their destination. Unfortunately, the default configuration of WordPress, which uses the PHP <code data-no-auto-translation=\"\">mail()<\/code>is often unreliable and may be blocked by some hosts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To guarantee optimum deliverability, the use of a <strong>SMTP<\/strong> is the recommended solution. <strong>MailerSend<\/strong>a service <strong>SMTP<\/strong> allows you to send your WordPress emails securely, quickly and reliably. In this tutorial, we'll show you step-by-step how to configure <strong>MailerSend<\/strong> as a server <strong>SMTP<\/strong> on WordPress using <strong>WPMasterToolKit<\/strong>so your e-mails always reach your users without a hitch.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What is MailerSend?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>MailerSend<\/strong> is a complete e-mailing service, combining a powerful infrastructure with advanced marketing features. Companies all over the world rely on it to manage both transactional and marketing e-mails, while guaranteeing an excellent deliverability rate.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cost :<\/strong> <strong>MailerSend<\/strong> offers a free plan including up to <strong>3 000<\/strong> e-mails per month (with a daily limit of 1,000 e-mails). Paid plans offer higher sending limits and additional features such as live support, A\/B testing and advanced analytics.<\/li>\n\n\n\n<li><strong>Sending e-mail requirements :<\/strong> You will need to use an e-mail address associated with your domain (for example, <a>vous@votredomaine.com<\/a>) to use <strong>MailerSend<\/strong> with WPMasterToolKit.<\/li>\n\n\n\n<li><strong>In a nutshell:<\/strong> <strong>MailerSend<\/strong> is an excellent choice for businesses of all sizes, offering a scalable e-mail infrastructure combined with powerful marketing features.<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Note:<\/strong> To find out more about compatible messaging services, visit the <strong>complete guide to mailers in WPMasterToolKit<\/strong>.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Setting up your MailerSend account<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To get started, you'll need to create an account <strong>MailerSend<\/strong> (if you don't already have one). To do so, go to <strong>MailerSend price list page<\/strong> and choose the plan that best suits your needs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In our example, we will use the <strong>free plan<\/strong>. However, the configuration process remains the same, whatever plan you choose.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img alt=\"\" fetchpriority=\"high\" decoding=\"async\" width=\"989\" height=\"540\" src=\"https:\/\/wpmastertoolkit.com\/wp-content\/uploads\/2026\/01\/image-47.png\" class=\"wp-image-5672\" srcset=\"https:\/\/wpmastertoolkit.com\/wp-content\/uploads\/2026\/01\/image-47.png 989w, https:\/\/wpmastertoolkit.com\/wp-content\/uploads\/2026\/01\/image-47-300x164.png 300w, https:\/\/wpmastertoolkit.com\/wp-content\/uploads\/2026\/01\/image-47-768x419.png 768w, https:\/\/wpmastertoolkit.com\/wp-content\/uploads\/2026\/01\/image-47-18x10.png 18w\" sizes=\"(max-width: 989px) 100vw, 989px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">After registering and validating your e-mail address, you will be redirected to the <strong>MailerSend account dashboard<\/strong>where you can start configuring your account.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Authorize your domain<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>MailerSend<\/strong> provides test logins to try out its e-mail service. You can use them if you want to test e-mail delivery before adding your own domain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this tutorial, we'll skip this step and go straight to adding a <strong>shipping area<\/strong>. This procedure verifies that you are the owner of the domain used to send the e-mail, and helps improve the deliverability of your e-mails.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Add your sending domain<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To add a sending domain, log in to your account <strong>MailerSend<\/strong>then go to <strong>Email \" Domains<\/strong> <strong><mark style=\"background-color:rgba(0, 0, 0, 0);color:#c0392b\" class=\"has-inline-color\">\u2780<\/mark><\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here you can see the details of your <strong>test area<\/strong>.
