Transform anonymous DMARC data into actionable user intelligence
Standard DMARC shows you IP addresses. DMARC HD reveals the actual email addresses behind every mail stream, turning guesswork into confident action for strict DMARC enforcement.
You've deployed DMARC. You're collecting reports. Your DMARC reporting vendor shows that SendGrid, Mailgun, or MailJet is sending email using your domain. But nobody in your organization admits to using these services.
Why? Because they don't know they're using them.
Your marketing automation platform uses SendGrid under the hood. Your CRM leverages MailJet for transactional emails. Your support system relies on Mailgun for ticket notifications. These services are buried layers deep in your SaaS stack.
Without this information, you face a difficult choice: stay vulnerable at p=none or risk blocking legitimate email by enforcing p=reject. It's a choice many make, but it's neither pleasant nor responsible when you're unsure which critical mail streams might be affected.
DMARC HD enhances standard DMARC with user level visibility by aggregating email intelligence from multiple points across the internet's mail infrastructure.

</record>DMARC HD adds crucial sender identity to standard DMARC data
This isn't RUA or RUF data. It's an entirely new intelligence stream that works alongside your existing DMARC infrastructure.
Transform anonymous vendor reports into clear ownership. Instead of "Someone is using SendGrid," you see "Sarah from HR sends the candidate newsletters through SendGrid."
View all users on your domain and their email activity patterns. Quickly identify who owns each mail stream by recognizing their sending schedule and volume.
Click any user to see their complete sending activity across all vendors and authentication status. Know exactly who to contact for remediation.
With complete visibility into mail stream ownership, you can coordinate authentication fixes before enforcement. No more choosing between security and functionality.
DMARC failure reports (RUF) were designed to provide message level detail when authentication fails. However, the reality is that failure reports are widely unsupported across the email ecosystem. Even when you've enabled RUF collection in your DMARC record and your vendor supports displaying them, most mailbox providers simply don't send them due to privacy concerns.
It's common to see RUA reports for millions of emails sent over a month without receiving a single RUF report. This leaves you blind to the details you need for troubleshooting.
Your DMARC report shows Mailgun sending 100,000 emails monthly, but IT, Marketing, and Sales all deny using it.
DMARC HD reveals that support@example.com and michael@example.com are the active senders. You discover your help desk software uses Mailgun for ticket notifications.
New, unauthenticated mail streams appear regularly as departments adopt new tools without IT involvement.
HD immediately identifies which users activated new services, enabling proactive authentication configuration before problems arise.
Generic ESP entries could represent dozens of different SaaS vendors all using the same underlying service.
User level visibility shows that invoicing@example.com uses SendGrid via your accounting software, while newsletter@example.com uses it through your marketing platform.
During email service migrations, you need to ensure all users have moved to the new platform.
Monitor individual user migration status and identify stragglers still using the old service.
Deliver 10x Value to Your Clients
Stop making your clients play detective. DMARC HD data transforms your platform from a reporting tool into an intelligence system that actually enables enforcement.
DMARC HD enhances standard DMARC with user level visibility. It reveals which email addresses are sending through each of your vendors and ESPs, transforming IP addresses into actionable intelligence.
Standard DMARC shows IP addresses. Most DMARC reporting vendors attempt to map these to vendor names. DMARC HD goes further by showing the actual email addresses using those vendors, enabling you to identify mail stream owners.
No. Failure reports only trigger on authentication failures and are rarely sent by mailbox providers. DMARC HD provides visibility into most email flows and actually delivers reliable data you can use.
Organizations with multiple departments, numerous SaaS tools, or complex email ecosystems benefit most. If you're trying to identify those last several vendors before enforcing DMARC, you'll definitely get value from HD.
DMARC HD is available through select DMARC vendors who have integrated the enhanced data feeds into their platforms. Raw XML feeds are also available for large enterprises and vendors.
Yes. DMARC HD aggregates data from multiple points across the global email infrastructure, providing coverage wherever email is sent.
DMARC HD reveals email addresses within your own domain only. It doesn't expose recipient information or message content.
