Sure!
1) Love the Subscribers functionality and look. Perfect.
2) Settings. Pretty good, but a few suggestions (and I have no idea how difficult or impractical these might be, so forgive me in advance)
> After you unsubscribes, could you return to the site’s home page?
> Is there a way to stipulate the specific address emails are sent from even if it’s from your own website (or a way to mask the host’s)?
Other than that, I love everything about it. ??
