What is DMARC? 

DMARC stands for Domain-based Message Authentication, Reporting, and Conformance, which is a policy used to increase the mail security.

For more information, please visit the link below.


Why DMARC matters to me? 

When you try to use your domain as a sender and your domain has DMARC policy enabled, your campaign emails could be rejected or quarantined because Phish Insight is actually using its own server to send the mail using your domain. 


What can I do? 

Add Phish Insight to your Allow List

For Microsoft Exchange / Office 365

For Google Workspace


What if I still having mail blocked/quarantine issue? 

Please contact our support team for further integration to pass the DMARC checking. You can open the chat widget at the lower-right corner of the portal or email us at phishinsight@trendmicro.com.
