Domain Warn List
**This endpoint returns a list of domains known to implement DMARC and categorizes them by failure type — hard failure or soft failure**. Domains listed as hard failures will not deliver mail when used as a [Sender Identity](https://sendgrid.com/docs/for-developers/sending-email/sender-identity/) due to the domain's DMARC policy settings. For example, using a `yahoo.com` email address as a Sender Identity will likely result in the rejection of your mail. For more information about DMARC, see [Everything about DMARC](https://sendgrid.com/docs/ui/sending-email/dmarc/).
