(This was already mentioned in Last entry in newsletter has messed-up user links, gravatars but not as an actionable feature-request.)
Gmail (which many people are surely using using to receive newsletters) imposes a limit on the size of HTML messages it will display:
So that I can conveniently read the entire newsletter rather than only part of it, I would like to request that some attention be given to reducing the size of the HTML which is used in the newsletter.
From what I can see, there is plenty of room for optimization; an absurd number of characters are used for click-tracking URLs, and also a substantial amount of indentation. Look at this single question! (Pardon the leftover MIME encoding =3Ds.)
