Together, they set out to answer a big question:
What if Lifecycle personalization could be as fast as the internet it runs on?
🎯 Goals
Optimizing lifecycle emails at scale. Success meant hitting three objectives:
📈 Lift in revenue and email KPIs from improved performance
⚡️ 10x greater testing efficiency
💡 Faster, proactive insights to inform product and marketing
📌 The Problem
Before Just Words, personalization Lifecycle messaging was slow and expensive:
Some cohort-level test required engineering lift and coordination
Performance readouts took hours of manual analysis across tools
Creative team bandwidth did not allow for multiple iterations of copy and limited to sprint cycles.
Despite having strong hypotheses and plenty of content ideas, bandwidth - not creativity - was the blocker.
💡 The Just Words Solution
In under 2 weeks, Coursera was live on Just Words, testing, optimizing, and learning across dozens of messages with no engineering help.
