Study Arms:
- No email (Type: None): No email will be sent out to this subset of GHP members during the week that the other emails are sent.
- Standard email reminder (Type: None): The standard email reminder mentions the average premium savings, the speed and ease of starting the process, and the deadline for registering and having health measures on file, plus it provides two button links for registering and finding free health screenings where health measures can be collected and registered at one convenient time and location.
- Social norms email (Type: None): The social norms email notes that a majority (78%) of GHP members' colleagues had enrolled in 2018, it provides a testimonial from a medical director at Geisinger's Commonwealth School of Medicine, stating the ways in which myHealth Rewards helped that doctor personally, and it emphasizes the simplicity and ease of taking the first step toward enrollment.
- Loss framing (Type: None): The loss framing email suggests that GHP members are currently throwing away a precise dollar amount (over $2,000) by not participating and that they can therefore avoid missing out on substantial gains (i.e., savings) by taking action.

Based on this trial design, predict the completion outcome and termination type (if applicable).
