The jnteresting thing about politeness is how it varies between cultures and persons. Things really can very widely.
I personally can't imagine emailing someone only to ask "may I ask you a question" rather than asking the question itself, but I suppose that might be more polite with some folks?
In the case of this original message, I literally have no idea what half of it meant. English isn't my first language, but I think I've got it pretty down. This was a whole new (generational?) level. 😅
