Data-Driven Email Optimization

Project description

Textbroker wanted to improve the performance of its French monthly newsletters, which shared the latest blog updates and relevant landing pages. My approach to boosting open and engagement rates was conducting A/B tests on subject lines by exploring variations in tone, personalization, and styling.

A/B Testing

Optimize open rates and click-through rates

To maximize email engagement, I implemented a targeted A/B testing approach on subject lines, experimenting with questions versus bold statements, personalization (recipient names), and styling (capitalization and punctuation). This data-driven strategy achieved a +23% increase in open rates and a 1.5% boost in CTR, successfully engaging over 3,000 clients and driving consistent improvements in email metrics.

Data-Driven Personalization

Refine messaging through real-time performance insights

Using real-time analytics, I tracked open and click-through rates, iterating on each test to refine subject lines. This enabled personalized, high-performing email campaigns tailored to specific client segments, reinforcing Textbroker’s brand authority and driving better ROI on outreach efforts.

Better Email Engagement

Drive measurable results across a growing client base

The iterative testing process provided actionable insights into client preferences, building a repository of best practices for future campaigns. By identifying high-performing subject line styles, the optimized newsletters reached a broader audience more effectively, significantly improving engagement rates.
