How a countdown clock added to an email appeal impacts click through
Experiment ID: #6126
National Breast Cancer Foundation
Experiment Summary
Timeframe: 12/30/2016 - 12/31/2016
In the final days of a year-end campaign, urgency plays a key role in people making gifts to an organization. On the second to last day of NBCF’s year-end campaign, they hypothesized that they could increase the urgency of the ask by adding a countdown clock to their emails. They developed a treatment that had a countdown clock added to the top of the email copy and test this against their control that didn’t have the countdown clock on it.
Research Question
Would the addition of a countdown clock in an email help get more people to click through to the donation page?

Results
| Treatment Name | Click Rate | Relative Difference | Confidence | |
|---|---|---|---|---|
| C: | Without a countdown clock | 1.4% | ||
| T1: | With countdown clock | 0.85% | -38.7% | 66.6% |
This experiment has a required sample size of 2,956 in order to be valid. Unfortunately, the required sample size was not met and a level of confidence above 95% was not met so the experiment results are not valid.
Key Learnings
Because NBCF’s email file is still in it’s infancy, there was low engagement and we weren’t able to validate the results. From the data that we were able to collect, the addition of the countdown clock received less clicks than the control that didn’t have the countdown clock.
We recommend testing this approach again once the email file has been cultivated more and there is a large enough sample size.
