Write it once. Send it.

They draft, and this leans on that rather than pretending otherwise. What a drafting tool can't do is decide what the email should achieve, judge whether the draft actually says it, or handle the messages where tone is the entire point — a refusal, a late payment, a correction to a client. Those need a person who knows the shape. There's also the practical issue that pasting client details into anything is a decision your employer may have a view on, which is why the course works on anonymised versions.

No, and you state your norms before any advice is given. Legal, regulated and technical writing genuinely needs detail, and the course is explicit about where cutting would be a mistake. What changes even in formal contexts is the order — the point near the top rather than the bottom — and the padding that adds length without adding precision. Formal and long are not the same thing.

That's the fear behind most over-long business writing, and it's worth naming: warmth comes from specific word choices, not from extra sentences. A message can be four lines and read as friendly, or twenty lines of hedging and read as evasive. Week three is entirely about tone, including which words actually carry warmth so you stop adding length in place of them.

It usually makes this more useful, not less. Second-language writers often over-explain and over-hedge because they're compensating for uncertainty, which is exactly the habit that adds length. Working on structure and clear asks tends to help faster than working on vocabulary, and every rewrite comes back annotated so you can see which of your own patterns to drop.

Follow it — this sits underneath a style guide rather than against it. Most guides cover formatting, signatures and terminology and say very little about the thing that actually costs you time: what goes in the first two lines and what gets cut. If a specific rule conflicts, your employer's guide wins and the rest still applies.
