A/B Testing Optimization
Run automatic subject line and content variant tests and let Evox select the winning version.
Evox tests subject line and content variants, tracks open and click rates per variant, and selects the winning version automatically through the Testing Worker, with no manual setup required.
How it works
You create multiple email variants, and Evox distributes them across audience segments using statistical sampling. The system tracks performance for each variant in real time, then the Testing Worker applies statistical analysis (confidence intervals and significance testing) to determine the winner. Once the confidence threshold is reached, the winning variant is promoted to full campaign distribution.
Key capabilities
- Create multiple subject line and content variants for a single campaign.
- Distribute variants across audience segments with statistical sampling.
- Track open rates, click rates, conversions, and engagement per variant in real time.
- Automatic winner selection via the Testing Worker using confidence intervals and significance testing.
- Automatic promotion of the winning variant to full deployment once statistical confidence is reached.
- Learning across campaigns to inform future variant generation.
Tips
The Testing Worker handles sample sizing, confidence intervals, and significance behind the scenes, so you do not need to configure statistical thresholds manually.
