Why we publish here

DMARC Guardian helps teams monitor SPF, DKIM, and DMARC alignment across their domains. This blog is a public channel for short product notes, operator guidance, and release highlights.

What to expect

• Practical explainers tied to features you see in the app
• Security-conscious defaults we apply to ingestion and reporting
• No paywalled knowledge: if it helps the ecosystem, it belongs here
