BACKGROUND

Ensuring a Secure and Authenticated Email Ecosystem

As a digitally native beauty brand, Glossier relies heavily on email for customer engagement, order confirmations, and brand communications. With an ever-growing roster of third-party platforms sending emails on its behalf, Glossier needed a way to ensure strong email authentication without the manual upkeep of SPF and DKIM records—especially across multiple subdomains and a complex sending infrastructure.

They turned to Valimail to bring automation, visibility, and peace of mind to their email authentication strategy.

Valimail has completely transformed how we manage email authentication. Their automation gives us confidence, and their customer support team has been incredible—especially during urgent, high-stakes moments.

CHALLENGE

Manual Maintenance of SPF & DKIM with Third-Party Senders

Glossier’s email program involved a diverse set of third-party senders—from marketing platforms and customer service tools to logistics and transactional email systems. As their email ecosystem evolved, so did the complexity of maintaining:

  • Accurate SPF records with proper include mechanisms
  • Timely DKIM key rotations
  • Alignment across multiple sending domains and vendors
  • A clear understanding of what Valimail owned vs. what was managed via Cloudflare

With limited internal resources focused on DNS management and mission-critical email deliverability at stake, Glossier needed a solution that would simplify authentication and provide fast, reliable support when needed most.

SOLUTION

Automation + Clarity from Valimail

Valimail provided Glossier with a fully automated platform to manage SPF and DKIM records across all their domains—eliminating guesswork and manual edits. With Valimail, Glossier was able to:

  • Automate DKIM key rotation and SPF management, reducing the risk of expired or misconfigured records.
  • Gain full visibility into third-party senders, including which were properly authenticated and which needed attention.
  • Use Valimail’s intuitive interface to easily delegate and control access across teams and partners.
  • Quickly identify where ownership and responsibility lay between Valimail-managed records and configurations handled via Cloudflare.
