Use ChatGPT Work to Turn an Approved Launch Memo into a Reviewable Email Sequence

A launch memo often contains enough material for several emails, but it is rarely written as one. This documentation-based, illustrative workflow shows how to turn a fictional approved memo into a three-email sequence without letting AI invent dates, pricing, or promises.

Prerequisites

You need ChatGPT with the Work experience available in your account, an approved source memo, and a human who can approve copy before sending. ChatGPT describes Work as an agent for longer, multi-step work and finished deliverables. Access and model options depend on the plan and workspace settings. Do not upload confidential customer or employer material to a personal workspace.

Sample input

Use this fictional memo in a new chat:

Product: DeskBoard, a shared team task board
Audience: small operations teams
Launch window: 6 to 17 November 2026
Confirmed facts: tasks have owners, due dates, comments, and a weekly email summary
Not confirmed: integrations, pricing, customer results, migration support
Approved CTA: reply to request a walkthrough
Tone: plain, useful, no urgency language

Steps

1. Open ChatGPT and select Work if it is available to you. If you cannot access Work, use a normal chat and keep the task smaller.
2. Paste the memo in full. Tell the tool that the memo is the only source of truth.
3. Use the prompt below. Ask for a claim ledger and approval questions as well as the draft emails.
4. Check the output against the memo. Delete any feature, date, result, price, or promise that is not supported.
5. Ask a human owner to approve the sequence and the final links. Do not send from the chat.

Copyable prompt

You are preparing a reviewable email sequence from the source memo below.

Create three short emails:
1. announcement
2. practical use case
3. final reminder within the stated launch window

Rules:
- Use only facts in the memo.
- Do not invent pricing, integrations, customer results, deadlines, scarcity, or support promises.
- Keep the approved CTA exactly as written unless you flag a suggested change.
- Add [CHECK] beside every claim that needs human confirmation.
- Return a claim ledger with: claim, source sentence, status, and reviewer question.
- Return a list of missing inputs before the drafts.
- Do not present the drafts as approved or scheduled.

Check the artifact

The result should contain three separate drafts, a missing-input list, and a claim ledger. Each email should use only the confirmed facts. The CTA should be the approved reply request, and every unsupported item should be marked or removed. Treat the output as illustrative until you run the workflow yourself.

Common failure fixes

• If the drafts contain invented benefits, repeat that the memo is the only source of truth and ask for a claim ledger before rewriting.
• If the sequence feels repetitive, change the job of each email, not the facts. One can explain the use case while another answers a likely question.
• If Work is unavailable, use a regular chat with one email at a time and perform the same source check manually.

Limits and privacy

AI can organize approved information, but it cannot approve claims or send a campaign safely by itself. Keep personal data, confidential launch plans, and customer lists out of the example unless your workspace policy allows them. Verify dates and links immediately before use.
