All right, let's add a mailing list.
So I know I've got Mailgun use for Discourse (used for forum comments). Looking into the Mailgun documentation, I can see that there's an actual API for a mailing list. However the documentation shows Mailgun's implementation is more of a backend deal. Which would be fine if I had a dynamic application, but since I'm dealing with static pages, this is a major hangup.
