Yes, but it can be worth it as I've generally found that the most effective professional writing has your high-level request appear within the very first sentence.
This is because it as quickly as possible puts the reader into the context of what you need from them making your rationalization of the request reinforce it, whereas if you try to rationalize before getting to your request a busy reader (think customer support, exec, manager) will be thinking "Okay, okay, okay, what are they getting to? Okay, okay, oh there we go finally I know, now let's consider their rationalization, maybe I should scroll up and re-read".
I started doing this after having done email customer service many years ago, when you're expected to spend as little time as possible per support case, you will speed read their writing until you find the part which says what their issue is, for some emails this was paragraphs. A particularly memorable WoW case for me was something like this, but more verbose:
"I finished the raid last night where we managed to down , after we celebrated, I logged off. Then I woke up and went to school as usual, after getting home I tried logging on it showed a message saying I was banned, I was heart-broken as I've put so much time into the game and it means so much to me, so to find out why I logged into my Gmail and an email from you said I was banned due to ."
As a support person, all of that was completely irrelevant except for the part saying "I was banned due to " (which was commonly due account being compromised by a gold seller looting it and then auto-banned due to stuff they were doing on it).
Something else which reinforced my view of "get to the point quickly" was an HN comment saying how they were once sent on a course on "how as an engineer to communicate effectively with execs" which apparently essentially stated "write your email as you normally would, then at the end take the last paragraph and put it at the top of the email". The rationale being that execs are typically only interested in reading a full email if it's actually relevant to them.
