The number of DMARC messages in the free and paid plans is the number of the email messages that meet ANY of these criteria:
1) are sent from the user’s authorized IP addresses included in the user’s domain SPF record;
2) passed SPF evaluation;
3) passed DKIM evaluation.
It is recommended to choose a plan that covers the number of DMARC messages which is the same or is higher than the number of messages you send from all your legal sources per month.
If you exceed the quota for DMARC messages allocated by your plan, we will charge you an over-usage fee at the rate indicated on our pricing page. The over-usage fee for DMARC messages in custom plans depends on the number of DMARC messages covered by a custom plan.
