Email is the highest-frequency marketing task there is — welcome emails, newsletters, sales, abandoned carts, win-backs. Describe what the email should do, pick the type, the audience and the tone, and get a ready-to-paste prompt — with subject lines, a preheader and a sample email for every prompt below.
Pick a starter, or describe your own email — then generate, copy, and paste it into ChatGPT, Gemini or Claude.
Every prompt below comes with a sample subject line and a short sample email, so you can see what that kind of prompt produces. Copy any prompt as-is, or send it into the builder above and tune it.
Prompt: “Write a promotional email announcing a 20% off weekend sale on handmade candles to past buyers. Friendly tone, short, one call to action: shop the sale. Write 3 subject lines under 50 characters and a preheader.”
Subject lines: 1. 20% off this weekend only — your favourite candle is waiting 2. A little light, for a little less 3. Your candles miss you (and they're 20% off) Preheader: Weekend sale ends Sunday — free delivery over £25. Hi Sarah, Your favourite candle is back on the shelf — and this weekend it's 20% off. Hand-poured, small batch, and the same scent you ordered last time. Shop the sale before Sunday night, and we'll add free delivery on orders over £25. Warm wishes, The Candle Studio team P.S. The lavender one sells out first every time — don't wait too long.

Common questions about this email marketing prompt builder.
An email marketing prompt generator turns a rough email idea into a structured AI prompt: email type, audience, tone, goal and length — the details an AI needs to write an email that sounds like you and sells like a good salesperson. This one also writes 3 subject lines and a preheader, and every ready-made prompt comes with a sample subject line and a short sample email, so you can see what that kind of prompt produces before you use it.
Yes — completely free, with no signup and no limits. It runs 100% in your browser using templates, so nothing is sent to a server and your text never leaves the page.
One email type, one audience, one goal and one call to action. Name what the email should do — welcome, sell, win back, announce — who it is for, and what the reader should do next. The generator builds all of that in, plus subject lines and a preheader, so the AI writes a complete email instead of a vague draft.
The prompts are written to avoid the usual spam triggers: no ALL-CAPS subject lines, no excessive exclamation marks, no words like FREE!!! and no misleading promises. The rest depends on your sending setup — a verified sender domain, a clean list and a real unsubscribe link matter far more than the words in one email.
Short enough to read on a phone in under a minute: about 80–120 words for a sale or announcement, 150–250 words for a newsletter or a story-led email. One idea, one call to action. The generator's length setting keeps every email in that range.
Yes. Pick the email type first — newsletter, promotional, welcome, abandoned cart, re-engagement, sale, announcement or thank you — and the prompt is shaped for that job. The same prompt structure works in ChatGPT, Gemini, Claude or any AI writing tool.
No. This builder just writes the prompt and the email draft — you can paste the draft into any email tool, or send it from your regular email. The personalisation tokens like [First name] work in most email tools, including Mailchimp, Brevo, ConvertKit and Klaviyo.
No. The generator is template-based and runs entirely on this page. Your email idea, your product details and your list notes are never uploaded, stored or sent anywhere.
