Experiment Background

Experiment ID: #7821
Partner: Leadership Institute

The Leadership Institute recently sent a letter to their subscribers about the ‘Normandy Coalition’ –a new group of conservative and liberty-minded student organizations, policy groups, and legal defense foundations. As they developed this email copy, they wondered: Will a substantially longer email that includes more stories, examples, and value proposition language, increase motivation and donor conversion? They created a treatment version of the email and launched an A/B test to find out.

Research Question

Will extended value proposition language increase donor conversion in an appeal email?
