Zoho CRM is capable of sending DMARC compliant email because they support custom DKIM configurations that achieve DMARC alignment. Zoho CRM is a Customer Service Platform and is often used by Support.
We recommend opening a support ticket to get help with custom DKIM configurations as we couldn’t find any relevant ‘how to’ documentation on their site. The most recent support alias we found was at https://www.zoho.com/crm/support-plans.html.
