AI Lead Machine Agent

A fully automated local business lead generation and cold email outreach engine. Users submit a form specifying business type (e.g., "Plumber"), location (e.g., "Rome, Italy"), desired number of leads, and preferred email style (Friendly/Professional/Simple). The system scrapes Google Maps via Apify to collect business listings, filters results for those with websites, uses Google Gemini AI to extract email addresses from each business website, validates the emails, logs valid leads to Google Sheets, then loops through each lead with a 1-minute delay between sends -- using OpenAI GPT-4.1-mini to generate customized cold emails based on the company name, category, and selected tone -- sends via Gmail, and updates the sheet with send status and timestamp.

            -> Loop Over Items (batch processing)
              -> Wait 1 minute (rate limiting)
                -> OpenAI GPT-4.1-mini: Generate Cold Email (subject + body)
                  -> Edit Fields (timestamp + email)
