Create personalized B2B outreach emails with Tavily Research & OpenRouter LLM

🧠 About this workflow

This workflow automatically generates personalized B2B outreach email messages by combining AI-based company research and text generation.
It’s designed to help sales and marketing professionals automate the creation of tailored cold emails for prospects.

⚙️ How it works

1. Get rows from Google Sheets — Retrieves companies marked as “ready” for outreach.
2. Loop Over Items — Processes each company individually.
3. Company Research (LangChain Agent) — Uses the Tavily search tool to collect key company insights such as overview, offerings, and recent news.
4. Generate Outreach Message (LLM Chain) — Drafts a professional, concise, and fully personalized email body in English using the AI training context from YOUR_COMPANY_NAME.
   This example uses an AI training and automation service context, but you can easily modify the prompt to fit your own company’s products, services, or industry.
5. Add to Google Sheets — Writes the generated messages back into the sheet.
6. (Optional) Add to Instantly.ai — Sends the finalized lead data to your Instantly campaign for cold email distribution.

🧩 Troubleshooting

If the workflow does not generate emails or data fails to appear in Google Sheets, please check the following:

1. Google Sheets credentials — Ensure that the connected account has edit permissions and the document ID and sheet name are correctly set.
2. API keys — Verify that your OpenRouter and Tavily API credentials are valid and not expired.
3. Rate limits — Tavily and OpenRouter may throttle requests when processing multiple records. Try lowering the batch size in the “Limit” node.
4. Empty company background — If the “Company Research” node returns no output, make sure the input company name is correct and includes sufficient context (e.g., full company name, not abbreviation).
5. LLM output format — Ensure the “Generate Outreach Message” node is set to return plain text, not JSON or markdown.
6. Instantly.ai integration (optional) — If leads are not added, confirm that your API key and campaign ID are valid, and that the node is not disabled.

If the issue persists, enable “Always Output Data” in key nodes (such as Company Research and Generate Outreach Message) to debug intermediate results.
You can also use the Execution Log to inspect where the flow stops or returns an empty output.

⚠️ Disclaimer

This workflow uses AI language models and third-party APIs (OpenRouter, Tavily).
Ensure that you add your own API credentials securely and verify all AI-generated content before sending emails.
