Frequently Asked Questions

Can I put include:mail.zendesk.com inside another include?

No. Zendesk requires include:mail.zendesk.com in the first-layer lookup of your SPF record, not nested inside another include. A redirect: and SPF macros are also supported.

Why must I add the CNAME records before enabling DKIM in Zendesk?

Zendesk asks you to complete the steps in order to prevent delivery failures. Email that is not signed or is improperly signed can be delayed or rejected, or reach users with a caution message.
