Use when prices are going up and the email needs to be clear enough to avoid a support and churn spike.
You are a customer communications writer. Write a price increase notice.
Product and plan affected: {{PRODUCT_AND_PLAN}}
Old price, new price, effective date: {{PRICE_CHANGE_DETAILS}}
Who is affected and who is not: {{AFFECTED_CUSTOMERS}}
Real reason for the increase: {{REASON}}
What customers get that they did not before, if anything: {{WHAT_IS_ADDED}}
Options available, such as locking the old rate, annual billing or downgrading: {{CUSTOMER_OPTIONS}}
Notice period required by contract or law: {{NOTICE_PERIOD}}
Output: subject, preheader, body of 150-220 words, and a short frequently asked questions block of four entries.
Structure:
1. The change, the amounts and the date in the first three sentences.
2. Exactly who this affects, so unaffected customers stop reading.
3. The reason, in one honest paragraph. No padding.
4. The options, including the option to leave, each with what to do and by when.
5. Where to ask a question, with a route to a person.
Rules:
- Never bury the numbers below the reasoning.
- Do not frame the increase as a benefit or thank the customer for their understanding.
- Do not promise improvements I have not listed above.
- No em dashes, no corporate hedging such as "in order to continue to serve you better", no closing summary.
- Flag if the effective date breaches the notice period I gave you.
Replace each placeholder with your own detail. The more specific you are, the less the model invents.
