Why are DMARC aggregate reports important?

DMARC aggregate reports are important because they provide detailed information about how your domain's emails are being handled by email receivers. This information can help you to identify any issues with your DMARC implementation, such as messages that are failing SPF & DKIM evaluation. By analyzing these reports, you can make improvements to your email authentication protocols and enforce your DMARC policy to higher levels (such as p=quarantine or p=reject) and improve the deliverability of your emails.
