I’d say the mailing list does require an external tool: an email address and client. Most likely everyone already has this, but it is still an external tool. With the forum, a new user can follow a link, sign in, and immediately reply to a thread right on the same platform where they read it. With the mailing list a new user follows a link to the archive page and they can read the thread there, but not reply. In order to reply they must move to a different platform (email client) instead of the original place where they read the conversation (list archive).
