What this automation does
When you publish a new blog post, this automation reads the full article and transforms it into a newsletter-friendly format. It shortens the content to 300-500 words, adds a conversational intro, includes the key takeaways as bullet points, and ends with a CTA linking back to the full article. The output is ready to paste into your email platform.
Blog posts and newsletters serve different purposes. Blog content is optimized for SEO — longer, comprehensive, structured with headings. Newsletter content needs to be scannable, personal, and hook readers in the first two sentences. AI handles this format shift automatically.
Tools you need
- WordPress or CMS with RSS/webhooks: Triggers the automation when a new blog post is published
- OpenAI API: GPT-4 restructures the blog content for newsletter format ($0.03-0.08 per conversion)
- Zapier or Make: Connects your blog to OpenAI and pushes the draft to your email platform
How to set it up
Step 1: Create a Zapier zap triggered by new posts in your blog's RSS feed. Extract the full post content, title, featured image URL, and permalink.
Step 2: Send the blog content to OpenAI with a prompt that specifies your newsletter format: a casual, first-person intro (2-3 sentences that hook the reader), 3-5 key takeaways as bullet points, a brief paragraph expanding on the most interesting point, and a CTA that drives readers to the full blog post. Include your brand voice guidelines and a sample newsletter for reference.
Step 3: Push the generated newsletter draft to your email platform — Mailchimp, ConvertKit, or Beehiiv — as a new draft. Include the blog post's featured image and a 'Read the full post' button linking to the original article.
Step 4: Review and send. The AI draft typically needs 5-10 minutes of polish — adjusting the intro to reference current events or adding a personal anecdote. Compare open rates and click rates against your manually-written newsletters to gauge quality.

Frequently asked questions
Not if you add a personal touch. The AI handles the heavy lifting of restructuring content, but spend 5 minutes adding a personal intro — a quick story, a relevant observation, or a question. That human layer makes AI-generated newsletters indistinguishable from fully hand-written ones.
Yes. Instead of triggering per post, set up a weekly scheduled automation that pulls all posts published that week. The AI generates a digest-style newsletter with brief summaries of each post and links to read more. This works great for content-heavy teams publishing 3+ articles per week.
