Whether it's registration confirmations, form notifications or password resets, every e-mail counts. However, WordPress' default send function can sometimes be temperamental, and your messages may end up in spam or never arrive at all.<\/p>\n\n\n\n<p>Fortunately, the use of a <strong>SMTP<\/strong> professional as <strong>SendLayer<\/strong> can solve these problems, guaranteeing fast, secure delivery of your e-mails. In this tutorial, we'll take you step-by-step through the process of configuring <strong>SendLayer<\/strong> as a server <strong>SMTP<\/strong> on your WordPress site with <strong>WPMasterToolKit<\/strong>so your e-mails always arrive safely.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What is SendLayer?<\/strong><\/h2>\n\n\n\n<p><strong>SendLayer<\/strong> is a powerful, affordable and easy-to-use SMTP email service that works perfectly with WordPress and more <em><strong>1 000<\/strong> other platforms<\/em>.

Paid plans offer higher sending limits and many additional features. A credit or debit card is required to finalize your account registration. <strong>SendLayer<\/strong>.<\/li>\n\n\n\n<li><strong>Required e-mail address :<\/strong> You must use an e-mail address linked to your domain (e.g. exemple@votredomaine.com).<\/li>\n\n\n\n<li><strong>Conclusion:<\/strong> The mailer <strong>SendLayer<\/strong> is recommended because it's affordable and offers much more than just a mailing service. It combines a modern approach with enhanced reliability and security.<\/li>\n\n\n\n<li><strong>Note:<\/strong> Feel free to consult the <strong>SendLayer documentation<\/strong> to find out how to get started.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Setting up your SendLayer account<\/h2>\n\n\n\n<p>First of all, you need to <strong>create an account<\/strong> to connect your WordPress site to <strong>SendLayer<\/strong>. If you do not yet have an account, please consult the instructions for <strong>SendLayer<\/strong> to create a new account.<\/p>\n\n\n\n<p>Once your account <strong>SendLayer<\/strong> configured, <strong>log on to<\/strong> to your dashboard <strong>SendLayer<\/strong>. From here, you can start configuring the mailer, which we'll explain in detail in the following steps.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Authorize your domain in SendLayer<\/h2>\n\n\n\n<p>Before you can send e-mails with <strong>SendLayer<\/strong>you must <strong>authorize your domain<\/strong>. This process enables e-mail servers to verify that you are the owner of the sending domain and that your e-mails come from a legitimate source.<\/p>\n\n\n\n<p>For detailed step-by-step instructions on how to perform this operation, we recommend that you consult the guide <strong>SendLayer<\/strong> on your domain authorization.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">From Email<\/h2>\n\n\n\n<p>Visit <strong>From Email<\/strong> designates the address <strong>e-mail<\/strong> used to send all e-mails from your site. This address must correspond to the domain you have authorized in <strong>SendLayer<\/strong>.<\/p>\n\n\n\n<p>For example, if you have validated the <code data-no-auto-translation=\"\">example.com<\/code>your <strong>From Email<\/strong> must also use this domain (for example : <code data-no-auto-translation=\"\">contact@example.com<\/code>).<\/p>\n\n\n\n<p>By default, the <strong>From Name<\/strong> corresponds to the name of your site, but you can customize it with the text of your choice.<\/p>\n\n\n\n<p>The <strong>\"Force From Name<\/strong> allows you to apply this sender name to all e-mails sent from your site.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img
