+### Custom Domain Name Verification
+
+After creation of the custom email destination with your domain name, make sure its validated for the right ownership.
+This can be done with SPF and DKIM verification.
+* Sender Policy Framework (SPF), which is used to authenticate the sender of an email. SPF specifies the mail servers that are allowed to send email for your domain.
+* DomainKeys Identified Mail (DKIM), which allows an organization to take responsibility for transmitting a message by signing it. DKIM allows
+  the receiver to check the email that claimed to have come from a specific domain, is authorized by the owner of that domain.
