šØ Heads up: Microsoft is enforcing DMARC policies by 5th May 2025. If you don't want your emails being delivered to the junk folder, you're on the clock ā ļø
So what is DMARC, and why should you care?
DMARC (Domain-based Message Authentication, Reporting and Conformance) helps ensure only authorised senders can use your domain to send email. It works alongside SPF and DKIM to lock down your domain, and when done right, it improves deliverability and stops cybercriminals impersonating you.
š” Email deliverability wins
A DMARC policy improves inbox placement. DMARC isn't just a security concern, it affects marketing ROI
Gmail, Outlook, and others now prefer authenticated mail.
Cisco found that domains with a DMARC policy saw a 10% increase in delivery rates on average.Ā
No more getting dumped in spam for lack of proper authentication.
š”ļø Threat prevention
Impersonation is still the #1 tactic for phishing attacks.
According to Valimail, domain spoofing accounts for 90% of phishing attacksāand DMARC can stop them cold.
Domains with a strict DMARC policy saw a 96% reduction in spoofing attempts.
Even better, itās a win for trust: your customers, clients and suppliers are more likely to trust an email thatās actually from youānot some sketchy spoof.
āļø Not just for tech giants
Ā Whether you're a startup or a small business, implementing DMARC shows youāre serious about both comms and security.Ā
