For the most part it's excellent, and I love Hische's work, but the lowercase 'm' is not as distinct as before. It looks like it says "MailChirry".
For people who dig cursive writing that last part isn't great. But many only claim to like cursive writing. They don't actually use it or read it often.
I think phony cursive works well for this project, and goes well for the MailChimp esthetic overall.
