This protocol allows applications to transmit email messages over the Internet. Your email client connects to your mail server via SMTP and sends the messages.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In short, the SMTP service allows you to prevent spam from being sent via our mail server, and it usually requires SMTP or domain authentication.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Most used SMTP providers <\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">These services work with WordPress using SMTP plugins like <strong><a href=\"https:\/\/wordpress.org\/plugins\/wp-mail-smtp\/\" target=\"_blank\" aria-label=\"WP Mail SMTP (opens in a new tab)\" rel=\"noreferrer noopener\" class=\"ek-link\">WP Mail SMTP<\/a><\/strong> (if you want to check how to install and configure it on your site, please click <strong><a aria-label=\"here (opens in a new tab)\" href=\"https:\/\/wpx.net\/kb\/how-can-i-install-and-configure-an-smtp-plugin\/\" target=\"_blank\" rel=\"noreferrer noopener\" class=\"ek-link\">here<\/a><\/strong>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here we&#8217;ll check the most common SMTP providers and what they need to authenticate the domain.<\/p>\n\n\n\n<p class=\"wp-block-ht-blocks-messages wp-block-hb-message wp-block-hb-message--withicon is-style-info\"><strong>Sendinblue<\/strong> &#8211; You need to make an account first, and then you&#8217;ll get the necessary DNS records via e-mail.<\/p>\n\n\n\n<p class=\"wp-block-ht-blocks-messages wp-block-hb-message wp-block-hb-message--withicon is-style-info\"><strong>Mailgun<\/strong> &#8211; Here you need to use a subdomain and DNS records to authenticate your domain.<\/p>\n\n\n\n<p class=\"wp-block-ht-blocks-messages wp-block-hb-message wp-block-hb-message--withicon is-style-info\"><strong>Amazon SES<\/strong> &#8211; Here, you need to add an SPF and CNAME records.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How do these SMTP services work?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">First, you need registration for the service that you choose, and then they must provide you with clear instructions on what you need to do to authenticate the domain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In most cases, you need a couple of DNS records to add to your active DNS zone. Every SMTP service must provide you with the DNS records that need to be added. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here you can check the guides for some of the SMTP services (<strong><a aria-label=\"Sendinblue (opens in a new tab)\" class=\"ek-link\" href=\"https:\/\/know-how.wpxhosting.com\/link\/481#bkmrk-sendinblue---https%3A%2F\" target=\"_blank\" rel=\"noreferrer noopener\">Sendinblue<\/a><\/strong>, <strong><a aria-label=\"Mailgun (opens in a new tab)\" class=\"ek-link\" href=\"https:\/\/documentation.mailgun.com\/en\/latest\/quickstart-sending.html\" target=\"_blank\" rel=\"noreferrer noopener\">Mailgun<\/a><\/strong>, <strong><a aria-label=\"Amazon SES (opens in a new tab)\" class=\"ek-link\" href=\"https:\/\/docs.aws.amazon.com\/ses\/latest\/dg\/creating-identities.html#verify-domain-procedure?icmpid=docs_ses_console\" target=\"_blank\" rel=\"noreferrer noopener\">Amazon SES<\/a><\/strong>)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Stuck at any point?
