Put the answer in the first two sentences
The most common failure in business email is burying the decision. The reader opens a five-paragraph reply, cannot tell whether the answer is yes or no, and has to read the whole thing to find out. That costs both of you time and makes you look evasive even when you are not.
State the decision immediately, then explain. "We can meet the 15 March deadline, with one change to the scope" tells the reader everything they need in one line, and everything after that is supporting detail they can read or skip.
This is especially important for declines. A refusal padded with apologies reads as uncertainty, and uncertainty invites a second request. Decline once, clearly, then move to what you can do.
Matching register to the relationship
The same message needs different phrasing for a client, a manager, a peer and a vendor. A client needs reassurance and a clear next step. A manager needs the decision and the reasoning. A peer can be shorter and more direct. A vendor needs unambiguous instructions.
The relationship setting also affects how much justification you owe. To a client, you explain the reasoning because they are paying for it. To a colleague you have worked with for years, over-explaining reads as defensive.
Why the context field matters so much
The tool will not commit you to a price, a date, a discount, a scope change or a deadline that is not in your context notes. That constraint is deliberate: an AI drafting a commitment you did not authorise is a genuine business risk, not a hypothetical one.
So the context field is where you put your actual limits. "Budget capped at 40k, deadline cannot move, we already granted one extension" gives the tool the boundaries to negotiate within. Without it, the draft will be vague, because vague is the only safe thing to write when the constraints are unknown.
Anything the tool does not know appears as a [placeholder], which makes the gaps obvious before you send rather than after.
Preparing for the pushback
Each result includes a short prediction of the most likely objection and how to handle it. The most common one after a firm decline is a request for an exception, and the useful preparation is knowing in advance which exception you would actually grant.
There is also a condensed three-sentence version. Short replies are often more effective than long ones in internal communication, where the reader already has context and mostly needs the decision.
The prediction is worth reading before you send, not after. If you cannot imagine any objection to your reply, that usually means the reply is vague enough to avoid committing to anything, which is its own problem.
The reply you should not send
Some emails should not be answered in writing at all. If the message is heated, or if the stakes are high enough that a written record will matter later, the better move is a short acknowledgement followed by a request to talk it through. A two-line reply that says you will call this afternoon is often stronger than a carefully argued paragraph.
The same applies to anything that is genuinely a negotiation over money or scope. Email tends to freeze positions, because each side becomes reluctant to be the one who concedes in writing. Use the tool to draft your opening position and to prepare for the response, then have the actual conversation on a call.
And if you find yourself drafting a long reply to something that annoyed you, wait. The tool will write you a calm, professional version in ten seconds, which is exactly what you want, but you should still read it once more before sending rather than firing it off immediately.
