Rebuild the missing context
Assume the recipient will not remember every date, promise, or earlier conversation. For a message about how to request a refund for a subscription, use this factual base: list the amount, date, reason, receipt, prior agreement, and any part that remains genuinely disputed.
Say what needs to happen next
State the decision, information, or practical action you need and include a real deadline only when one exists. Propose a payment, refund, evidence exchange, or installment plan with dates both sides can assess. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Avoid making urgency into pressure
Do not threaten public exposure, add invented fees, or treat hardship as proof of dishonesty. Use secure payment methods and qualified banking, consumer, legal, or fraud support when appropriate. Do not make the other person responsible for reducing the discomfort that prompted you to write.
