The Group Subscription is an Outpost feature that lets you sell a group subscription to a business, school, or organization that shares an email address pattern.
For instance, you could sell a subscription so that anyone at Blue Sky College would be treated as a paid member when they log in with their blueskycollege.edu email address. Each member who joins gets the same expiration date.
With Outpost's group subscriptions, the subscription buyer doesn't have to submit a list of valid subsribers, as everyone at the organization is eligible and is automatically given paid privileges.
This feature currently does not have a limit on the number of paid subscriptions per email domain.
