n8n AI Agent that emails you Reddit Lead Summaries
What it is
This n8n workflow monitors Reddit for posts relevant to a specific business or industry, identifies potential leads, and delivers them directly to your inbox.
How It Works
1. A user submits their website URL and email through a form
2. The workflow analyzes the website to determine the industry and extract relevant keywords
3. It searches Reddit for posts containing those keywords and filters them based on engagement metrics (upvotes > 15, non-empty text content, posted within the last 90 days)
4. An AI agent (using OpenRouter's GPT-4.1-mini) analyzes each post to determine relevance and summarizes the key points
5. Relevant posts are stored in Google Sheets and formatted into a professional HTML email
6. The email is sent to the user's provided email address with a summary of potential leads
Setup
To run this workflow, you need to set up credentials in n8n for:
