Experiment ID: #2643
Dallas Theological Seminary
Experiment Summary
Timeframe: 10/11/2017 - 10/16/2017
Dallas Theological Seminary was making preparations to launch its new ‘mini’ course on the life and work of Martin Luther. They wondered: If we tell visitors to pre-enroll in this course by stressing the urgency of the upcoming launch date, will email acquisition increase? They launched an A/B test leading up to their launch date to find out.
Research Question
Will a Facebook ad that stresses the urgency of a course launch increase email acquisition?

Key Learnings
Dallas Theological Seminary found that the treatment version that stressed the upcoming launch date did, in fact, increase email acquisition by 88%. By using the actual date of the launch (October 16, 2017) and the word ‘Monday’ in their call-to-action, Dallas Theological Seminary was able to signal to viewers that this was an urgent offer with a specific launch date. It likely made viewers feel that they were going to miss out on a particular event, even though the course was still offered after the launch date.
This strategy has prompted further tests, especially as Dallas Theological Seminary builds plans to launch new courses.
