20 tested prompts across 4 stages. Works with ChatGPT, Claude, and Gemini.

Getting ChatGPT for Newsletter Writing right takes more than a single prompt. This 4-stage guide covers Plan your newsletter, Write the newsletter, Improve performance, and more, breaking the whole process into focused steps where each prompt builds on the last. Write newsletters that subscribers actually open, read, and share using ChatGPT to handle structure, copy, and engagement. Every prompt is tested and runs in ChatGPT, Claude, and Gemini.
Stage 1
Start here to plan your next issue before writing any content.
Define your newsletter concept
Help me define a newsletter concept for [TOPIC/NICHE]. Cover: target audience, core value promise, how often to send, format (digest vs essay vs tips), and what makes it different from other newsletters on this topic.
Choose a format
What newsletter format works best for [TYPE OF CONTENT]? Compare: long-form essay, curated links, weekly tips, Q&A, behind-the-scenes, or mixed. Recommend one for my audience of [DESCRIBE AUDIENCE].
Plan a content calendar
Create a 4-week newsletter content calendar for a [NICHE] newsletter. Each issue should have a theme, 2-3 content sections, and an angle that is different from the week before.
Write a welcome email
Write a welcome email for new subscribers to my [NICHE] newsletter. Include: what the newsletter is about, what to expect, and one piece of immediate value (tip, resource, or insight). Keep it warm and personal.
Define a consistent structure
Create a repeatable structure for my [NICHE] newsletter. Design 3-5 sections that appear every issue so readers know what to expect. Name each section and describe what goes in it.
Stage 2
These prompts help you write each section of your newsletter clearly and engagingly.
Write a full newsletter
Write a complete newsletter issue on [TOPIC] for [AUDIENCE]. Include: subject line, opening hook, 2-3 main sections with headings, and a closing CTA. Keep it under 600 words.
Write the opening
Write 3 different openings for a newsletter about [TOPIC]. Each should hook the reader in 2-3 sentences and make them want to keep reading. Try: personal story, surprising stat, and compelling question.
Write the main section
Write the main content section for a newsletter about [TOPIC]. Format: clear heading, 3-4 paragraphs with one core insight each, and pull out the most important point in a callout.
Write subject lines
Write 5 subject line options for a newsletter about [TOPIC]. Make each under 50 characters. Mix: curiosity, benefit, urgency, and personal address. Include 2 with preheader text.
Write the closing section
Write the closing section for my newsletter about [TOPIC]. Include: a takeaway that ties the issue together and a CTA (reply with a question, share with someone, visit a link). Keep it under 100 words.
Stage 3
Use these prompts to improve performance.
Test subject lines
I'm choosing between these subject lines: [LIST OPTIONS]. Which would likely get the highest open rate and why? Score each on: clarity, curiosity, specificity, and mobile display.
Improve readability
Reformat this newsletter for better readability: [PASTE NEWSLETTER]. Shorten paragraphs, add subheadings, use bullet points where appropriate, and cut any section that doesn't add value.
Add more personality
This newsletter sounds too formal / generic: [PASTE NEWSLETTER]. Rewrite it with more personality: add a personal anecdote, use more direct language, and make it sound like a specific human wrote it.
Write a re-engagement email
Write a re-engagement email for subscribers who haven't opened in [X MONTHS]. Be honest, warm, and give them a reason to stay. Offer something valuable and make it easy to unsubscribe if they want to.
Analyze what worked
My highest-open-rate newsletter was about [TOPIC]. What made it work? Suggest 3 follow-up issues that use the same principles to drive strong opens.
Stage 4
Use these prompts to attract the right subscribers and build a list worth owning.
Write a lead magnet
Write a lead magnet (free guide / checklist / template) to grow my newsletter about [TOPIC]. Make it immediately useful and directly tied to why someone would want the newsletter.
Write a referral CTA
Write a referral section for my newsletter that encourages existing subscribers to share it. Keep it natural and give them a good reason (and easy way) to forward it to someone.
Write a landing page
Write a short newsletter landing page for [NEWSLETTER NAME]. Include: headline, what the reader gets, social proof, and a simple email capture. Under 200 words.
Write a sponsored section
Write a sponsored section for my newsletter promoting [PRODUCT/SERVICE]. Keep it honest, on-brand, and integrate it naturally with the editorial content rather than making it feel like an ad.
Write a year-in-review issue
Write a year-in-review newsletter issue for [NEWSLETTER NAME]. Highlight: top issues, biggest lessons learned, what is changing in the new year, and thank subscribers for being part of it.
Most newsletters perform best at 300-600 words. Long-form newsletters can work at 1,000+ words if every paragraph earns its place and the topic demands depth. Short, punchy newsletters (under 300 words) work well for weekly tips or curated links.
Open rates vary by list size and niche. 30-40% is strong for a general newsletter; 40-60% is excellent for a niche list with a highly engaged audience. Focus more on growing an engaged list than inflating open rate metrics.
Give ChatGPT your real story, insights, and perspective. Use its output as a first draft and add personal details, specific examples from your own experience, and your actual voice. The more personal context you give it, the better the starting point.
Weekly is the most common cadence that builds habit without causing fatigue. Daily newsletters work only for highly engaged audiences who opted into high-frequency content. Monthly newsletters lose momentum and lose readers who forget they signed up.
Newsletters that make people feel smart, ahead of the curve, or part of an exclusive insight loop get shared. A section with a distinct original take, not just curation, gives readers something worth forwarding to a colleague.
