Case Study: Yelp achieves DMARC enforcement and streamlined email security with Valimail Enforce

Yelp Makes Easy Work of DMARC Enforcement with Valimail

Yelp, the global platform connecting millions of people to local businesses, needed a scalable way to protect its brand and users as its infrastructure shifted to the cloud. Achieving DMARC enforcement was slow and manual—two engineers took nearly a year to enforce a single domain—and Yelp lacked a technical solution for the SPF 10‑lookup limit, making it difficult to secure email at scale.

Yelp implemented Valimail Enforce™, which automated and centralized DMARC enforcement, provided full visibility into emailing and non‑emailing domains, and used patented technology to overcome SPF lookup limits. The platform reduced tedious manual work, gave the security team a single dashboard to manage 70 monitored domains, authenticated over 3 billion emails and blocked nearly 1 million suspicious messages, and enabled faster, more flexible onboarding of new email senders.
