to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Be delivered to the spam folder.<\/li>\n\n\n\n<li>Be rejected by recipient mail servers.<\/li>\n\n\n\n<li>Display warnings about the sender&#8217;s identity.<\/li>\n\n\n\n<li>Have lower open and engagement rates.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">MailerLite uses DNS records to verify domain ownership and authorize email sending.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"DNS_Records_Required_by_MailerLite\"><\/span>DNS Records Required by MailerLite<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When you authenticate a domain in MailerLite, the platform will provide one or more DNS records that must be added to your domain&#8217;s DNS zone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Common record types include:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"CNAME_Records\"><\/span>CNAME Records<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">CNAME records are used to verify domain ownership and enable MailerLite features such as click tracking and link branding.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Type: CNAME\nName: litesrv._domainkey\nValue: litesrv.mailerlite.com\n<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"SPF_Records\"><\/span>SPF Records<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">SPF (Sender Policy Framework) records specify which servers are allowed to send email on behalf of your domain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>v=spf1 include:_spf.mailerlite.com ~all\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">If your domain already has an SPF record, do not create a second one. Instead, update the existing SPF record to include MailerLite&#8217;s authorization mechanism.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"DKIM_Records\"><\/span>DKIM Records<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">MailerLite may also provide DKIM records. DKIM adds a digital signature to outgoing messages, helping recipient servers verify that emails have not been altered during delivery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Adding_DNS_Records_in_mybox\"><\/span>Adding DNS Records in mybox<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Log in to the mybox control panel.<\/li>\n\n\n\n<li>Open the <strong>Domains<\/strong> section.<\/li>\n\n\n\n<li>Select your domain.<\/li>\n\n\n\n<li>Click <strong>Manage DNS<\/strong>.<\/li>\n\n\n\n<li>Add the records exactly as provided by MailerLite.<\/li>\n\n\n\n<li>Save the changes.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">If an SPF record already exists, edit the existing record rather than creating a duplicate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Verifying_the_Configuration\"><\/span>Verifying the Configuration<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">After the DNS records have been added, return to MailerLite and start the verification process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DNS changes are not applied instantly. Depending on DNS propagation and cache expiration, verification may take anywhere from a few minutes to 24 hours.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once verification is complete, MailerLite will confirm that your domain has been successfully authenticated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Troubleshooting\"><\/span>Troubleshooting<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If verification fails:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Check that record names and values were copied exactly.<\/li>\n\n\n\n<li>Make sure there are no duplicate SPF records.<\/li>\n\n\n\n<li>Confirm that DNS changes have had time to propagate.<\/li>\n\n\n\n<li>Verify that records were added to the correct domain.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">You can use online DNS lookup tools to confirm that the records are publicly visible before attempting verification again.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Summary\"><\/span>Summary<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Authenticating your domain in MailerLite is an important step in improving email deliverability and protecting your domain&#8217;s reputation. By correctly configuring the required DNS records in mybox, you ensure that newsletters, marketing campaigns, and automated messages are more likely to reach recipients&#8217; inboxes successfully.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"template":"","format":"standard","manualknowledgebasecat":[41],"manual_kb_tag":[204,339,797,1282,1676,5826,7759,7760,7761,170],"class_list":["post-8336","manual_kb","type-manual_kb","status-publish","format-standard","hentry","manualknowledgebasecat-email","manual_kb_tag-dns-records","manual_kb_tag-email-deliverability","manual_kb_tag-email-authentication","manual_kb_tag-sender-policy-framework","manual_kb_tag-domain-verification","manual_kb_tag-dns-record-verification","manual_kb_tag-domain-authentication","manual_kb_tag-domain-keys-identified-mail","manual_kb_tag-text-record","manual_kb_tag-dns-propagation"],"_links":{"self":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb\/8336","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb"}],"about":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/types\/manual_kb"}],"author":[{"embeddable":true,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":2,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb\/8336\/revisions"}],"predecessor-version":[{"id":8337,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb\/8336\/revisions\/8337"}],"wp:attachment":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/media?parent=8336"}],"wp:term":[{"taxonomy":"manualknowledgebasecat","embeddable":true,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manualknowledgebasecat?post=8336"},{"taxonomy":"manual_kb_tag","embeddable":true,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb_tag?post=8336"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
