Google and Yahoo have introduced a new requirement: if you're sending over 5,000 emails per day, you'll need to deploy DMARC (Domain-based Message Authentication, Reporting, and Conformance). This security protocol helps ensure that emails are legitimately sent from your domain, reducing the risk of phishing and unauthorized use of your domain name for malicious purposes. Meeting this requirement is essential for anyone who sends a high volume of emails to maintain a secure and trusted email delivery system.
