Board-level email notifications for end-users (Subscribe to Board)

I want a feature where all users in a group or on a board can be automatically notified via email whenever a new feedback entry is posted. We are migrating from an internal forum where people are used to receiving a notification for every new post, and we need this same behavior in Featurebase to successfully migrate our feedback board. Currently, only admins get these notifications, but we need it for our end-users/employees as well.
