Create Curated Reddit Newsletters with GPT-4o Mini & Gmail

This workflow transforms fresh Reddit discussions into professional HTML newsletters. It pulls the latest posts from a specified subreddit (e.g., r/microsaas), ranks the top 10 by upvotes, comments, and recency, then applies an AI filter to select posts matching a user-defined topic of interest using GPT-4o Mini.

For each filtered post, it fetches comments, cleans and structures them, and leverages OpenAI to generate summaries including main post insights, comment highlights, and key learnings. These are compiled into a beautifully formatted HTML newsletter featuring headlines, post sections, quotes, and stats.

Finally, it delivers the newsletter directly to your inbox via Gmail. Benefits include massive time savings on content curation, staying ahead on niche trends without manual effort, and scalable for business intelligence or marketing. Ideal for solopreneurs, marketers, or communities tracking subreddits like microsaas, startups, or crypto.
