TL;DR
Right now, families are only ever emailed one time about any given study. For studies with longer timelines, and when families haven't had any other studies to take, it might be good to send families additional emails/invitations. (Researchers would obviously like this as well)
Possible implementations could include: "second email" criteria for sending, and/or a digest with all available studies. It would make sense to wait to implement this until we also have 'remind me' and 'hide this study' functionality to give families the right kinds of control over these!
