Specifies the percent of unauthenticated messages that are subject to the DMARC policy. When you gradually deploy DMARC, you might start with a small percentage of your messages. As more messages from your domain pass authentication with receiving servers, update your record with a higher percentage, until you reach 100 percent.

DMARC should be rolled out gradually: Start with a policy set to none (no enforcement for 100% of messages) for one week: Messages are delivered normally. There is no risk of messages being rejected or marked as spam. Review your DMARC reports daily to identify any issues with your outgoing email or email senders.

To pass DMARC authentication, outgoing messages must pass either SPF or DKIM. Check the DMARC policy and alignment settings for your domain. A DMARC policy with strict alignment increases the likelihood that messages are rejected or sent to spam. Check your DMARC daily reports to identify which outgoing messages don’t pass SPF, DKIM, or DMARC.
