Daily Newsletter Summarization & Briefing
Automatically collects daily newsletters, summarizes them via AI, and sends a single structured briefing to your inbox.
What it does
Receive a concise daily briefing in your inbox that automatically gathers newsletters from Gmail, removes clutter, and summarizes the key points into one clear digest. You get a structured overview of your daily reading without manually scanning multiple emails or long articles.
Step by step
- Configure the Gmail trigger to filter by specific sender addresses or labels like 'Newsletter' to isolate relevant emails.
- Use a LangChain code block with regex or BeautifulSoup to strip HTML tags and extract plain text from the email body.
- Implement logic to split extracted text into chunks that fit within Google Gemini's token context window before sending to the model.
- Format the final output as a JSON object containing fields for 'headline', 'key_points', and 'action_items' to ensure consistent structure.
Where the LLM does the work
- Craft system prompts that instruct the model to prioritize actionable insights over general fluff in the summary.
- Tune the temperature parameter to balance creativity with factual accuracy when generating the daily digest.
- Design few-shot examples within the prompt to demonstrate the desired tone and formatting style for the recipients.
Watch out for
Large newsletters may exceed token limits so you must implement a robust chunking strategy that preserves context boundaries.
HTML parsing can fail on malformed emails so add error handling to fallback to raw text extraction if cleaning fails.
Email attachments are not processed by default so explicitly instruct users to forward only text-based newsletters or strip attachment references.

You are helping me build the following AI agent workflow. ## Goal Daily Newsletter Summarization & Briefing: Automatically collects daily newsletters, summarizes them via AI, and sends a single structured briefing to your inbox. ## Specification - What it does: Receive a concise daily briefing in your inbox that automatically gathers newsletters from Gmail, removes clutter, and summarizes the key points into one clear digest. You get a structured overview of your daily reading without manually scanning multiple emails or long articles. - Trigger: On a schedule (Scheduled · daily) - Autonomy: Fully hands-off - Expected setup effort: about an afternoon - Tools/services involved: - Gmail: Collecting newsletter emails - Google Sheets: Logging text chunks - LangChain Code: Processing and splitting text - Google Gemini Chat Model: Summarizing content into digest - Send Email: Delivering the daily briefing ## Known pitfalls, handle each one explicitly in your implementation 1. Large newsletters may exceed token limits so you must implement a robust chunking strategy that preserves context boundaries. 2. HTML parsing can fail on malformed emails so add error handling to fallback to raw text extraction if cleaning fails. 3. Email attachments are not processed by default so explicitly instruct users to forward only text-based newsletters or strip attachment references. ## Reference implementation https://n8n.io/workflows/9633 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Email than Gmail?
Yes. Gmail is only the example email in this recipe. The same flow works with Brevo, KlickTipp, Lemlist and Mailchimp. Swap the email connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
Built for founders and execs who need personal productivity handled without hiring for it.
