The Context: What DMARC Data Revealed

With support from Imagetext, Orion Health strengthened its defenses against domain impersonation.

The turning point was visibility. DMARC reporting revealed:

  1. The scale of impersonation targeting Orion Health’s domain
  2. Which legitimate sending sources were failing authentication

The Challenge

DMARC data showed significant impersonation activity, while SPF limit issues affected deliverability. Imagetext therefore needed to help Orion Health regain control of outbound email quickly and with minimal disruption.

The challenges included:

  • Increased exposure to brand impersonation and customer fraud
  • Higher chance of legitimate email being rejected or landing in Spam
  • Slower investigation and remediation due to fragmented visibility
  • Delayed progress due to limited internal capacity and insufficient day-to-day access controls

Requirements

Orion Health needed a solution that could provide:

  1. SPF remediation to address the 10-lookup limit
  2. One consolidated view of all sending sources and DMARC outcomes
  3. Proactive alerting to flag DMARC misalignment early
  4. Audit and compliance logs for change monitorability
  5. SSO (single sign-on) aligned with enterprise access controls
  6. Expert guidance for SPF, DKIM, and DMARC

Results

  • SPF optimization enabled, reducing authentication failures
  • Clearer visibility into DMARC pass and fail results
  • Proactive alerting enabled for misalignment detection
  • Audit and compliance change logs improved traceability
  • SSO enabled for simpler, controlled access
  • Delegation enabled for DMARC, SPF, and DKIM

What Imagetext Had To Say:

“Imagetext spent some time reviewing different DMARC providers in the market and eventually settled on Sendmarc. The Sendmarc products and platform were easy to scale based on different customer needs. From a small SMB to a large enterprise like Orion, the platform had all the capability.

Imagetext was able to bring this solution to the table for Orion, offering a free assessment so they could see their own data and the value the platform provided. The onboarding experience meant we had Orion on a p=reject policy within 50 days.”
