You know exactly what you need to say — you just don't want to spend twenty minutes saying it politely. This playbook turns five bullet points into a polished, purpose-built email by locking recipient, goal, tone and length into the prompt before the model writes a word.
Workflow area: Writing & Email · Tier: Foundation · Hands-on time: ~20 minutes
The difference between a mediocre AI email and one you can send unedited is almost never the model — it is whether you told it who is reading, what you want them to do, and how the message should feel. That frame takes thirty seconds to write and saves ten rounds of "make it shorter, make it warmer."
Write your bullets first, before opening any AI tool. Three to seven bullets: the facts, the ask, any dates or amounts. If you cannot write the bullets, the problem is that you don't yet know what you want — no model fixes that.
Fill in the four-lock frame. Recipient, goal, tone, length. This is the whole trick. Paste this prompt into ChatGPT, Copilot, or Gemini:
Draft an email from these bullet points.
Recipient: [WHO — role and your relationship, e.g. "my client's finance
director; we've met twice, cordial but formal"]
Goal: [WHAT THEY SHOULD DO after reading, e.g. "approve the revised
quote by Friday"]
Tone: [e.g. "professional, warm, not pushy"]
Length: [e.g. "under 120 words, 2 short paragraphs"]
Bullet points:
- [POINT 1]
- [POINT 2]
- [POINT 3]
Rules: Use only the facts in my bullets — do not invent details,
commitments, or dates. Write a subject line. No em-dash-heavy or
flowery phrasing. End with a single clear ask.
Read the draft as the recipient, not the sender. Good output looks like this — short, specific, one ask:
Subject: Revised quote — approval needed by Friday
Hi Meera,
Following our call on Tuesday, I've attached the revised quote with
the updated delivery schedule (now 6 weeks) and the 4% volume
discount we discussed.
Could you confirm approval by Friday the 14th so we can hold the
production slot? Happy to jump on a quick call if anything needs
clarifying.
Best regards,
Arjun
If the draft buries the ask in paragraph three or invents a pleasantry that isn't true ("Hope the conference went well!" — which conference?), fix the frame, not the draft.
Iterate with targeted edits, not "try again." "Make paragraph 2 one sentence." "Replace 'as per our discussion' with plain language." "The deadline is firm — remove 'if possible'." Each instruction should name what changes; regenerating from scratch loses what was already right.
Do the final pass yourself. Check every name, date, and number against your bullets, then adjust one or two phrases into your own voice. A single sentence you actually wrote makes the whole email sound like you.
[NAME] and [PROJECT], ask the model to keep placeholders intact, and fill them per recipient — or feed a small table of names and details and ask for all twelve variants in one pass. Read every variant; personalization is where models quietly recycle the wrong detail.Never paste salary figures, disciplinary details, unreleased financials, or customer personal data into a consumer AI tool — use your organization's approved tenant (M365 Copilot or Workspace with enterprise data protection) or genericize the bullets first; pb-12 covers the full pre-flight.
Save your filled-in four-lock frame the first time an email lands well — recipient type, tone words, length cap. Next time it's a 15-second paste-and-edit, and after ten emails you'll have the start of the prompt library pb-05 builds properly.
