Control and treatment groups:
40% of recipients will be assigned to the control group.
30% of recipients will be assigned to the treatment 1 group.
30% of recipients will be assigned to the treatment 2 group.
Treatment 1: The subject of the email will be "Emission reduction potential, topic2, topic3, and more". The section about ERP will be at the top of the newsletter (out of 5 sections).
