Email Newsletter Prompt ✉️

Stop staring at a blank screen every week. Describe your topic once and get a complete, send-ready newsletter: five subject line variants, preview text, a three-section body that opens with a story and closes with a clear CTA, plus a P.S. that almost always gets read.

The prompt

Write a complete email newsletter for my audience of [AUDIENCE, e.g. freelance designers] on the topic: [TOPIC, e.g. how to raise your rates without losing clients].

Include, in this exact order:


    

  1. Five subject line variants (under 50 characters each, mix of curiosity, benefit, and urgency styles).
    2. 

  2. Preview text (40–90 characters) that complements the subject line without repeating it.
    3. 

  3. A warm greeting that uses the subscriber’s first name placeholder.
    4. 

  4. A three-section body, 350–500 words total:

      

    • Section 1 (Story): open with a short, relatable personal story or anecdote that sets up the topic.
      • 

    • Section 2 (Value): deliver the core lesson — 3 actionable takeaways with specific examples.
      • 

    • Section 3 (CTA): one clear call-to-action with a single link, explained in 2–3 sentences.
      • 

    

    5. 

  5. A P.S. line that reinforces the main benefit and repeats the CTA.
Tone: [TONE, e.g. friendly, direct, slightly witty], like a note from an experienced friend. Avoid jargon. Use short paragraphs (2–3 sentences) and one subhead per section.
Then provide an A/B variant: rewrite the subject line and the first 100 words of the body in a more direct, no-fluff style so I can test which converts better.
## Preview — what this prompt creates You get back a finished email you can paste straight into ConvertKit, Mailchimp, Beehiiv, or Substack. The five subject lines give you a month of A/B test material, the story opening lifts reply rates, and the P.S. line often outperforms the main CTA because it's the last thing readers see. The A/B variant lets you run a real split test instead of guessing which voice your list prefers. ## Best AI tools for this - **ChatGPT (GPT-4o / GPT-4)** — best all-rounder, strong subject lines - **Claude (Opus / Sonnet)** — excellent long-form storytelling tone - **Gemini Advanced** — fast, good at matching a brand voice if you paste examples - **Jasper** — built-in email templates and brand-voice training - **Copy.ai** — great for generating many subject-line variants at once ## Make it yours - **[AUDIENCE]** — be specific ("parents of toddlers" beats "parents"); the AI writes sharper copy when it knows exactly who is reading. - **[TOPIC]** — one topic per email. Bundling three ideas dilutes the CTA. - **[TONE]** — paste two paragraphs of your own past newsletters and add "match this voice exactly" for best results. - **Word count** — raise it to 700 for deep-dive issues, or drop to 200 for a quick tip roundup. ## Pro tips - Always replace the AI's generic anecdote with one real story from your week — authenticity is the biggest open-rate lever you have. - Send at a consistent time; consistency beats "optimal send time" research. - Track your reply rate, not just opens — replies tell you the content actually landed. - Never use all five subject lines on one send. Rotate them across your next five newsletters.
