CaringBridge

Experiment Summary

Timeframe: 5/7/2015 - 7/14/2015

CaringBridge had an automated email as part of their new name conversion strategy that had been sent in a designed template using their founder as the sender for years. They wanted to test this against a more personal, text-only email from another member of the development team.

Research Question

Will a less-designed, more personal email increase clickthrough rate?

Design

C: Control
T1: Treatment 1

Results

Treatment Name Click Rate Relative Difference Confidence
C: Control 6.3%
T1: Treatment 1 8.4% 32.5% 100.0%

This experiment has a required sample size of 1,241 in order to be valid. Since the experiment had a total sample size of 14,351, and the level of confidence is above 95% the experiment results are valid.

Flux Metrics Affected

The Flux Metrics analyze the three primary metrics that affect revenue (traffic, conversion rate, and average gift). This experiment produced the following results:

    32.5% increase in traffic
× 0% increase in conversion rate
× 0% increase in average gift

Key Learnings

This was a big lift that delivered a lot more traffic to the landing page. Follow-on conversion didn’t significantly increase, so there is more testing to be done on the landing page to improve that metric.
