Update your DNS records through your hosting provider to finish setting up self-authentication

Work with your hosting provider to create a new CNAME, TXT, or DMARC record in your DNS settings to complete your DKIM setup

Once you've generated your DKIM information, you must publish it in your domain's DNS records. DKIM setup requires advanced access and knowledge of your domain settings and hosting services. Due to the complexity of different DNS providers, we are unable to assist with the implementation of the DKIM key, but we can point you in the right direction:

• Create a new DNS record
• Hosting providers that add your domain to a CNAME, TXT, or DMARC record

Tip: If you're unsure where your DNS is hosted, you can do a lookup with this tool.

Create a new DNS record

Every DNS interface should be able to create a CNAME, TXT, or DMARC record, but each DNS admin console is different. If you're having trouble locating where to add the DKIM information, please reach out to the support for your hosting provider:

Hosting providers that add your domain to a CNAME, TXT, or DMARC record

When self-authenticating using a CNAME or TXT record and adding the provided DKIM information to your domain's DNS records, you should be creating a new CNAME or TXT record just for the DKIM key value and its host name. A common misconception is that the DKIM key is part of your domain's DMARC policy. The DKIM key functions independently of DMARC and is only used by the DMARC framework to authenticate email being sent on the domain's behalf by a third party outside of that domain's own IP addresses and mail servers.

Some DNS providers may automatically add your domain to the CNAME, TXT, or DMARC record by default. If this is the case for your DNS provider, the first half of the key as provided can be added to the Host Name/Record without your domain. For example, the Host Name/Record for DKIM TXT should be input as “2020223150._domainkey” instead of "2020223150._domainkey.halfmoonyogastudio.com". For CNAME, the record name should be input as “ctct1._domainkey” and “ctct2_domainkey” instead of “ctct1._domainkey.halfmoonyogastudio.com” and “ctct2._domainkey.halfmoonyogastudio.com”.

Here is a list of providers that may automatically add your domain to a CNAME, TXT, or DMARC record:

• Bluehost
• CloudFlare
• Codero 
• cPanel (WHM)
