Case Study: Burson achieves global email standardization and higher deliverability with Mailjet

How a top global communications agency streamlined its email systems, empowered local teams, and increased customer engagement

Burson, a global communications agency operating across 43 markets, struggled with a patchwork of email tools and processes that made it hard to standardize communications, track performance, maintain compliance, and achieve strong deliverability. It needed a single email platform that could serve both global consistency and local flexibility, and chose Mailjet after evaluating more than 30 options.

Mailjet implemented a centralized email solution with a flexible editor, list management and segmentation, list hygiene tools, real-time analytics, and dedicated subdomains for each office. With Mailjet’s onboarding support, Burson trained thousands of staff in three months, doubled email send volume month over month, and saw top offices sending over 100,000 emails per month; it also achieved a 30% average open rate and delivery rates above 90%, while improving domain reputation and compliance.
