Our blog shares expert insights on email security, DMARC configuration, and deliverability optimization.
For a decade, DMARC used a volunteer-maintained text file to find the organizational boundary for domains like news.example.co.uk. RFC 9989 replaces that lookup with a DNS tree walk. Here is what changed and what to check.
Managing DMARC across multiple domains means logging into GoDaddy, Cloudflare, Route 53, and more. Human error is the top cause of DMARC failures. A centralized multi-domain dashboard catches mistakes before they hurt deliverability.
Publishing SPF, DKIM, and DMARC records is just the start. Without monitoring, you won't know when authentication breaks, new senders appear, or someone starts spoofing you.
Marc's note on the part people miss after creating a DMARC record: reports, sender inventory, alignment work, and why a DNS string alone does not protect a domain.
Monitoring pain is mostly workflow pain: DMARC aggregate reports (RUA) are XML (often compressed), arrive on imperfect schedules, and are hard to triage. We explain how to turn the XML firehose into actionable security insights.
The biggest practical blocker to moving beyond p=none isn't DNS syntax. It's discovering every legitimate sender. DMARC reports expose these "unknown senders" and Shadow IT that you didn't even know existed.
