Zendesk has made changes to its email authentication requirements. You now need to add 3 new DNS records to your domain to improve email deliverability and help prevent support emails from going to spam.
Log in to your domain providers website. And go to the DNS settings. Add the 3 records below.
Record Type | Host | New Value |
CNAME | zendesk1._domainkey | zendesk1._domainkey.zendesk.com |
CNAME | zendesk2._domainkey | zendesk2._domainkey.zendesk.com |
TXT | _dmarc | V=DMARC1; p=none |
Once completed. Zendesk will verify these and your support ticket deliverability improvements will have been implemented.
