When first logging into the Safeguard Send dashboard, you are looking at your main subscription page.
In general, a subscription contains information about the state of the subscription (subscribed, unsubscribed, etc. along with other information like the number of seats, etc.) and one or more rule sets.

Click Save and that’s it! Anyone using the add-in will see the changes take effect immediately.
