Starting May 2025, Microsoft will strictly enforce DMARC policies across Outlook and Exchange Online.
This isn't just another update—it’s a major move in the war against email spoofing, phishing, and impersonation.
✅ DMARC protects your brand.
✅ Improves email deliverability.
✅ Shuts the door on impersonators.
If your SPF/DKIM/DMARC isn’t configured properly? Your emails might get quarantined or blocked entirely.
Here’s what to do now:
1️⃣ Set up SPF & DKIM – cover all sending services (like Mailchimp, Google, M365)
2️⃣ Publish a DMARC record – start with p=none to monitor
3️⃣ Analyse reports with tools like EasyDMARC or Valimail
4️⃣ Gradually enforce (move from quarantine → reject)
5️⃣ Audit every third-party sender – your CRM, invoicing, and marketing tools
🔍 Doing nothing = broken campaigns, lost trust, compliance headaches.
This isn’t just an IT task. It’s a brand protection move. It’s a compliance step for frameworks like PCI DSS 4.0.1 and ISO 27001.
Let’s make sure your emails hit inboxes—not junk folders.
