The exact steps vary depending on your registrar, but the core information remains the same.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What you&#8217;ll need from Sitecore Send<\/h2>\n\n\n\n<p>Before touching your DNS settings, grab these details from your Sitecore Send account:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Your DKIM public key (includes at least p=; may also include v=DKIM1; k=rsa;)<\/li>\n\n\n\n<li>The selector name (typically ms._domainkey)<\/li>\n\n\n\n<li>Your domain or subdomain<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Step 1: Log in to your DNS management panel<\/h2>\n\n\n\n<p>Locate the DNS records for your domain (these may be hosted by your registrar or hosting provider).<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Registrar<\/td><td>Where to find DNS settings<\/td><\/tr><tr><td>GoDaddy<\/td><td>Domain Settings \u2192 DNS Management<\/td><\/tr><tr><td>Namecheap<\/td><td>Domain List \u2192 Manage \u2192 Advanced DNS<\/td><\/tr><tr><td>Cloudflare<\/td><td>DNS tab on domain overview<\/td><\/tr><tr><td>AWS Route 53<\/td><td>Hosted Zones \u2192 Select domain<\/td><\/tr><tr><td>Squarespace Domains<\/td><td>Domains dashboard \u2192 Manage DNS<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Most registrars store DNS settings under &#8220;DNS Management,&#8221; &#8220;Advanced DNS,&#8221; or a similar section.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 2: Create a new TXT record<\/h2>\n\n\n\n<p>Click &#8220;Add Record&#8221; or &#8220;Add New Record&#8221; in your DNS panel. You&#8217;ll need to fill in three fields.<\/p>\n\n\n\n<p>Record type: Select TXT.<\/p>\n\n\n\n<p>Name\/Host\/Alias: Enter ms._domainkey exactly as shown. Some registrars auto-append your domain, so you only need to type ms._domainkey instead of ms._domainkey.yourdomain.com.<\/p>\n\n\n\n<p>Value\/Content\/Text: Paste the full DKIM public key from Sitecore Send. Don&#8217;t modify it or add spaces.<\/p>\n\n\n\n<p>TTL: Choose &#8220;Auto&#8221; or set it to 300-3600 seconds (5 minutes to 1 hour works fine).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 3: Save and wait for DNS propagation<\/h2>\n\n\n\n<p>After saving the record, DNS changes need time to spread across the internet.&nbsp;<\/p>\n\n\n\n<p>Cloudflare&#8217;s Auto TTL (300 seconds) ensures changes take effect within minutes.&nbsp;<\/p>\n\n\n\n<p>Many registrars take around 30 minutes. Some providers still cite 24-48 hours (rare but possible on slower DNS infrastructure).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 4: Verify in Sitecore Send<\/h2>\n\n\n\n<p>Return to your Sitecore Send account and click the verification button.&nbsp;<\/p>\n\n\n\n<p>A green checkmark confirms that the setup was successful. If it fails, double-check your TXT record for typos or extra spaces.<\/p>\n\n\n\n<p>Running an <a href=\"https:\/\/emailwarmup.com\/email-deliverability-test\" target=\"_blank\" rel=\"noreferrer noopener\">email deliverability test<\/a> after verification ensures that your authentication is working across various inbox providers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common setup variations by registrar<\/h2>\n\n\n\n<p>A few registrars handle things differently:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>cPanel users (Namecheap, Bluehost, HostGator): Access through cPanel \u2192 Zone Editor<\/li>\n\n\n\n<li>Wix: DNS settings are under Domain Settings, not the main dashboard<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">What happens if the DKIM setup fails<\/h2>\n\n\n\n<p><a href=\"https:\/\/emailwarmup.com\/blog\/dkim-fail\/\" target=\"_blank\" rel=\"noreferrer noopener\">DKIM failures<\/a> usually come from these mistakes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Typos in the selector name (ms._domainkey)<\/li>\n\n\n\n<li>Missing characters in the public key value<\/li>\n\n\n\n<li>Selecting CNAME when you should use TXT (or vice versa for Network Solutions)<\/li>\n\n\n\n<li>Not waiting long enough for DNS propagation<\/li>\n<\/ul>\n\n\n\n<p>Re-check the exact values from Sitecore Send against what you entered in your DNS panel.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Maintaining your DKIM after setup<\/h2>\n\n\n\n<p>Once verified, DKIM works automatically.&nbsp;<\/p>\n\n\n\n<p>The private key remains with Sitecore Send (they sign your emails), while the public key is stored in your DNS (receiving servers use it to verify signatures).&nbsp;<\/p>\n\n\n\n<p>You don&#8217;t need to touch it again unless you migrate to a different email platform or decide to rotate keys for security (recommended every 6-12 months, though not all platforms automate this).<\/p>\n\n\n\n<p>If you&#8217;re sending cold outreach campaigns, pair proper authentication with <a href=\"https:\/\/emailwarmup.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">email warmup<\/a> to build sender reputation gradually.
