Experiment ID: #100506

Experiment Summary
Timeframe: 07/13/2022 - 07/19/2022
For NIO Summit 2022 we ran a flash sale and want to test the subject line to see which one would lead to more click-throughs. We wondered which language would create more urgency around the deadline: “Today only” vs. “discount ends at midnight”.
Research Question
We believe that “Today Only” language for people interested in a NIO ticket will achieve more urgency and more click-throughs to the NIO website.

Key Learnings
Overall, the “Today Only” language did achieve more click-throughs than the treatment version of the subject line. We will do further testing to narrow in on specific language for NIO subject lines. Urgency seems more effective than mystery in this case.
Notable changes to other metrics due to the experiment:
- Opens experienced a 4.3% increase with a 97% level of confidence.
- Clicks experienced a 24.2% decrease with a 94% level of confidence.
