Prompt
Write a short email newsletter for [business name]. Audience: [describe customers]. This month's news: [list]. One offer: [offer + deadline].
Use British English, a friendly tone, a subject line under 45 characters (give me 3 options), short paragraphs and one clear button text.
Only use the facts, prices and dates I've given you.

UK note: you mustn't send marketing emails or texts to individuals without their specific consent. There's a limited exception for your own previous customers, the "soft opt-in". In plain words: you can email existing customers who bought (or discussed buying) something from you, about similar products or services, as long as you gave them a clear chance to opt out when you collected their details and you give them one in every email. It doesn't cover new contacts, such as bought-in lists (ICO: https://ico.org.uk/for-organisations/direct-marketing-and-privacy-and-electronic-communications/guide-to-pecr/electronic-and-telephone-marketing/electronic-mail-marketing/, checked 16 Oct 2026, 05:34 BST). All marketing must be accurate and truthful (https://www.gov.uk/marketing-advertising-law, checked 16 Oct 2026, 05:34 BST).
