In October, the CSA announced its partnership with Orange, one of Europe’s largest mailbox providers. The news received strong attention across the industry, and rightly so.

Today, we would like to take a closer look at what this partnership means in practice and how it contributes to a healthier email ecosystem.

This collaboration represents a key step toward improving email quality, protecting end users, and supporting responsible senders in France and beyond.

“This strategic collaboration aims to enhance the quality and reliability of email communications. By promoting best practices in emailing, we want to provide our customers with a safer, more transparent experience, free from unwanted advertising messages. Thanks to this partnership, we are helping to fight spam and promote more respectful and effective digital communication. Together, for a healthier online environment!”

Enhancing Email Quality and Reliability

Together, CSA and Orange work to improve the quality and reliability of email communication. Through consistent promotion and monitoring of best practices, compliant senders benefit from stronger trust signals and improved deliverability stability.

Protecting End Users

For Orange customers, the partnership means fewer unwanted advertising messages and a more transparent inbox experience. The cooperation also supports efforts to combat spam and improve overall message relevance for users.

Improved Performance for Certified Senders

The partnership provides meaningful advantages for CSA certified senders:

• More predictable performance in the Orange ecosystem
• Controlled data exchange between Orange and CSA senders
• Faster trust-building for new IPs/domains without established reputation

This enables compliant senders to reach Orange users more effectively while upholding a high standard of quality and transparency.

Trust and Reputation Management

Orange applies the CSA IP List as a supplementary trust factor alongside its own reputation systems.
This means:

• New senders benefit from a trust advantage when following CSA standards
• Established senders continue to be evaluated by Orange’s own filtering and reputation mechanisms
• Users remain fully protected, as Orange retains independent anti-abuse controls

Oversight and Responsibility

All data shared within this partnership is handled responsibly and used exclusively to support legitimate, compliant email communication.

A Shared Mission

The CSA and Orange share a common goal: to promote respectful, effective, and high-quality digital communication, and to contribute to a safer, more transparent online environment.

The technical implementation is expected to be completed by Q1 2026, marking the next milestone in this important collaboration.
