Wording Clarification on Email Lists
This is a tiny change and won't gather many votes. But it's easy and would smooth the learning curve for new admins.
In the Compose your email screen, change the wording of the button from "Add contact list" to "Add saved search or subscription list". Or abbreviate to "Add search or subscription".

Oops. I didn't understand that subscription lists can't be emailed directly, only through a saved search. That's counter-intuitive.
So revise this suggestion to name that button "Add saved search."
And a second, slightly harder suggestion: This button now brings up a list of saved searches. That list should also include subscriptions. The purpose of a subscription is to email to it. So why not just let us do that, without creating a saved search to duplicate the subscription?
