Email Address
When you have a name or username but need to find associated email addresses.
Prioritized Sources & Techniques
Domain-based email search; find corporate email patterns
Scrape search engines, PGP servers, and DNS for emails associated with a domain
Automated OSINT scan across multiple data sources from a domain or name
"firstname lastname" "@gmail.com" OR "@yahoo.com"
Check commit history — Git commits embed author email in metadata
Academic papers list author contact emails
Corporate filings sometimes include executive contact emails
Patent filings list inventor correspondence addresses
Recommended Workflow
Start with Hunter.io if you know the target's employer domain. For individuals, use theHarvester against known associated domains. Check GitHub commits for developer targets. Google Scholar papers routinely list corresponding author emails.
