2018 ACS Mail Materials Test Report

Written by:

The 2018 Mail Materials Test tested ideas that combined results from years of ACS field tests, collaborative research with Reingold, Inc., and other outside research. This test consisted of six experimental treatments and one control treatment that used production ACS materials. Three of the treatments tested variations on the use of mandatory messaging, one treatment tested removing materials, one treatment tested changes to the questionnaire cover, and one treatment tested the type of pressure seal mailer used in the third and fifth mailing.
