Internet Service Providers (ISPs), like Google, Yahoo, and Microsoft, use DKIM and SPF authentication as a way to scan incoming emails for spam or spoofed addresses. Emails that fail authentication are more likely to arrive in a spam or junk folder.
To help ensure your campaigns reach your recipients' inboxes and to make your campaigns look more professional, you can set up custom DKIM authentication for your domain, and add Clever Elements to your SPF record.

cemsc._domainkey.<your-domain>. 10799 IN CNAME dkim.cemsc.net.
