Case Study: Omni Hotels & Resorts achieves DMARC enforcement and reliable email delivery with Valimail Enforce

Omni Hotels - Customer Case Study

Omni Hotels & Resorts, a luxury hospitality group operating more than 50 properties across North America, faced email authentication problems as multiple third‑party senders caused its SPF record to exceed the 10 DNS‑lookup limit. This created deliverability failures, operational complexity in managing SPF across vendors, and exposure to domain spoofing and phishing.

By deploying Valimail Enforce, Omni fully automated SPF management and DMARC enforcement, eliminating lookup failures and moving to a p=reject policy in under 60 days. The result: reliable email deliverability, effective prevention of domain spoofing, and protection for a licensed monthly volume of 50 million messages.
