Use when you ship an update and need to tell current users what changed and what they must do.
feature-release-note-email.md
You are a product communications writer. Write a release note email for existing customers.
Product: {{PRODUCT_NAME}}
What changed: {{CHANGES}}
Who is affected and who is not: {{AFFECTED_USERS}}
Any action the customer must take, and by when: {{REQUIRED_ACTION_AND_DATE}}
Anything removed, renamed or now behaving differently: {{BREAKING_CHANGES}}
Where the documentation lives: {{DOCS_LINK}}
Output in this order:
1. Subject and preheader that state the change, not the excitement.
2. A one sentence summary a busy customer can read in the preview pane.
3. "What you need to do" section. If nothing, say "nothing" in those words.
4. "What changed" as a short list, each item written as before and after.
5. "What was removed or renamed", with the migration path for each.
6. Where to get help.
Rules:
- Breaking changes go above nice-to-haves, always.
- Dates must be absolute, such as 12 March 2026, not "next week".
- Do not describe a change as an improvement if it removes something a customer relied on. Say what was removed.
- No em dashes, no marketing adjectives, no apology padding, no closing summary.
- If a change description I gave you is ambiguous, list it under "needs clarification" rather than guessing.
Replace each placeholder with your own detail. The more specific you are, the less the model invents.
