I've been working on email lead generator for a while and wanted to share what I learned.
The problem
Automatically discover and collect verified business email addresses from any industry or niche. Perfect for sales teams, marketers, and freelancers who need a steady pipeline of qualified leads without manual research.
What I built
Here are the main features I ended up shipping:
- Bulk email discovery from domains and websites
- Email verification and bounce detection
- Export to CSV, JSON, or CRM-ready formats
- Rate limiting and proxy support for safe scraping
- Configurable filters by role, domain, and industry
Code sample
# Basic structure
class Bot:
def __init__(self, config):
self.config = config
def run(self):
while True:
self.scan()
self.execute()
If you want the full working version with all the battle-tested edge cases
handled, I packaged it here: Email Lead Generator
Happy to answer questions about the architecture in the comments.
