You don't need advice on the email. You need the email.
The tool that turns the email you are avoiding into three complete drafts, each pursuing a different outcome, each with the reasoning made explicit. Drop in the situation, pick the one you can defend.
Most difficult-email advice obsesses over tone. Tone is downstream. The actual question is what outcome you are trying to produce: preserve a relationship, force a decision, create urgency, contain damage. Different outcomes need different emails.
Strategic Email makes the three versions visible. You drop in the situation, what has happened, what you want, what they want. It produces three complete drafts, each pursuing a different outcome, with explicit reasoning about which to use when. You pick. You send. You move on with your day.
Three drafts, three outcomes, your call.
Same situation, same five minutes. Here is the email, run two ways.
A client is six weeks late on a £12k invoice and has gone quiet on your finance team. They are also a logo you would rather not lose. You need to escalate without torching the relationship.
You ask Claude how to handle it. You get good counsel. Acknowledge the relationship, be firm but warm, set a deadline, offer a path forward, escalate to a senior contact if no response. Maybe a sample paragraph.
All true. And you are still sitting in front of a blank email, because the hard part was never the principles. It was committing to one.
It does not tell you how to write it. It writes three, each chasing a different outcome:
- →Draft A, preserve the relationship: assumes good faith, offers a payment plan
- →Draft B, force the decision: names the impasse, sets a date
- →Draft C, quiet escalation: brings their CEO into the thread without announcing it
Each is 150 to 200 words, send-ready, with a use-this-when note. You read three real options instead of one set of principles, and the choice you were avoiding becomes obvious the moment you see them side by side. You pick C, change one paragraph, send. They reply inside a day.
The cold version gave you a better understanding of your problem. This gave you the thing you needed to send.

What it does with a real question.
I need to reply to a client who has just emailed to say our last two deliverables were late and that they are considering moving the account. We were late because they changed the scope twice. I want to keep them, but I do not want to accept blame for a delay they caused. The relationship is eight years old and worth about 18% of revenue.
My read: you are not defending a deadline, you are defending an eight-year relationship, and 18% of revenue is not worth winning an argument over. But "accept blame" and "preserve the relationship" are not the same thing, so you do not have to choose between them.
The outcome to aim for is a client who stays and who also sees, without being told, that the scope changes drove the timeline. Any draft that opens with a defense will read as the first move in an exit negotiation. Any draft that opens with a flat apology will quietly rewrite history and invite the same complaint next quarter.
So lead with the concern, not the cause. Acknowledge that two late deliverables is a real problem from their side of the table. Then give the sequence as plain, dated fact: the original scope, the two change requests, what each did to the schedule. No adjectives, no "as you know." Let the dates do the arguing. Offer one process fix, such as a short change-order step that states the delivery impact before work starts, so this cannot recur on either side.
The risk is tone. Keep it warm, short, and under 200 words. Do not cc anyone new.
Next move: pull the two change-request emails today, build the three-line timeline, and propose a 20-minute call this week. The call is where you rebuild the relationship; the email just earns you the meeting.
The full Tool runs the whole procedure and writes the complete deliverable, not this excerpt.

Before you buy.
How is this different from just asking Claude directly?
Asked cold, Claude gives you principles for the email and you still have to write it, which was the part you were avoiding. This produces three complete, send-ready drafts, each pursuing a different outcome, each with a note on when it is the right one. You are choosing between real options, not reading advice.
Will this work with ChatGPT, Gemini, and other LLMs?
Yes. You get a native Claude Skill (.zip) that auto-invokes in Claude, plus a plain .md you can paste into a ChatGPT Custom GPT, a Gemini system prompt, or any LLM. The procedure travels with the file.
Can I share this with my team?
It's licensed for your own personal and professional use. The output it produces is yours to circulate. To put the Tool itself in the hands of a whole team, email hello@authority.md about team licensing.
