This is more of a StackExchange network request than one for SO itself, but here goes:
Generally speaking the bit of logic that picks questions for the email newsletter does a good job of picking questions that are interesting to people who subscribe to the newsletter.
Since these questions are sent to all the subscribers, I like to make sure that they're of high quality and give people an impression that they're getting the best of the best. When I receive the newsletter I typically open each one, do some edits, clean things up, flag, and other typical things I normally do in the /review queue.
I think it would be great if there was a bit of a lead time for people who unlocked the /review privileges to either get the newsletter a little bit earlier or perhaps have those questions pop up in the /review queue so that they can have some human eyeballs give them a once over and improve them if need be.
