Puma Europe grows email revenue 5x and lifts open rates 5–10% with AI send time optimization
By deploying SAP Emarsys AI-powered send time optimization alongside behavioral segmentation across multiple European markets, Puma Europe achieved a 5–10% lift in email open rates, triple-digit year-over-year email revenue growth, and a 5x increase in email's share of total business revenue — all within six months.
Background
PUMA Europe was mass-sending to its full email database with minimal segmentation, producing generic experiences that failed to reflect individual customers' product preferences, engagement patterns, or purchase timing. The company needed to move from broadcast email to individualized engagement at scale, across multiple European markets and languages.
What Was Implemented
- Deployed SAP Emarsys CRM platform for lifecycle segmentation, content personalization, and send time optimization
- Segmented database by engagement level: concentrated sends to high-intent customers; limited sends to less-engaged subscribers
- Applied behavioral product affinity modeling to serve dynamically matched product recommendations based on browsing and purchase history
- Activated Emarsys AI-powered send time optimization (STO) to deliver emails at each subscriber's individual peak engagement window
- Scaled via pre-built localized templates across multiple European markets and languages
Results
Within six months: 5–10% lift in email open rates from STO; open and click-through rates at 20–25% ; no increase in unsubscribes ; 5x increase in email's share of business revenue ; triple-digit year-over-year email revenue growth ; 50% database growth ; scaling from ~1,000 to ~10,000 new subscribers per week at peak.
Lessons
- Send time optimization's 5–10% open rate lift may appear modest in isolation, but at scale and combined with content personalization, it drives outsized revenue impact
- Segmenting sends by engagement level — and deliberately limiting frequency to lower-engagement segments — is as important as personalizing content
- Pre-built templates with automated localization allow multicountry, multilingual personalization to scale without proportional headcount increases
- Database growth and engagement improvement are mutually reinforcing: better-targeted emails produce higher subscriber satisfaction, supporting list growth
