Measure	Standard Email This email mentions the cost-saving benefits of enrollment by participants who met their 2018 goals. It also includes the message that registration can be completed quickly (in less than five minutes). Finally, it also includes reward incentive information, wherein registering by a March deadline provides qualified recipients with the potential to win prizes. This information is contained in all other emails.	Loss Frame Email In addition to the content of the generic email, the subject line and content of the loss frame email recommends that GHP members not "throw away" a precise dollar amount in savings (over $2,000) by not participating and that they can therefore avoid missing out on substantial gains (i.e., savings) by taking action. This email further frames the reward as something recipients will miss out on if they do not sign up.	Testimonial (Medical Expert) Email In addition to the content of the generic email, the testimonial (medical expert) email includes a testimonial from a doctor, which notes the personal benefits of myHealth Rewards in terms of managing blood pressure, blood sugar, cholesterol, weight, and stress.
