email-finder
Find email addresses for a domain by combining website scraping, search dorking, pattern guessing, DNS analysis, and SMTP verification. Use when prospecting leads, finding contact emails for outreach, or building contact lists from a company domain. Optionally provide a person's name to generate and verify common email patterns.
Why use this skill?
Automate domain reconnaissance with the Email Finder skill. Scrape, guess patterns, and verify email deliverability for efficient lead generation and OSINT workflows.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/psyduckler/email-finderWhat This Skill Does
The email-finder skill is a sophisticated intelligence-gathering tool designed to identify and verify professional email addresses associated with a specific domain. By leveraging a multi-layered approach, it combines passive information gathering with active verification protocols. The process begins with website scraping across key pages like contact, about, and team sections. It supplements this with search dorking techniques to locate indexed email data. If a specific person's name is provided, the tool utilizes pattern guessing based on industry-standard conventions (such as first.last or flast). Crucially, it performs DNS analysis to identify the email infrastructure provider, followed by an SMTP verification step that validates the deliverability of findings without triggering actual inbox notifications. It is the definitive solution for automated lead generation and domain reconnaissance within the OpenClaw ecosystem.
Installation
To integrate this skill into your environment, ensure you have Python 3 installed. Navigate to your OpenClaw skills directory and use the install command: clawhub install openclaw/skills/skills/psyduckler/email-finder. Additionally, ensure the core dependency is active by running pip3 install dnspython. This library is essential for the tool's ability to parse MX, SPF, and DMARC records during the initial reconnaissance phase.
Use Cases
This skill is highly versatile for professionals in sales, recruitment, and cybersecurity. Sales development representatives use it to build targeted outbound mailing lists. Recruiters leverage the pattern guessing feature to reach out to potential candidates directly. Cybersecurity researchers utilize the tool for OSINT investigations or to map an organization's digital footprint and external-facing mail server configurations.
Example Prompts
- "Find all public-facing email addresses for the domain techcorp.com and verify their status."
- "Look up contact emails for [email protected] and try to guess the email address for 'Sarah Jenkins' at the same domain."
- "Scrape info.org and check for deliverability, but limit SMTP checks to 5 to avoid triggering rate limits."
Tips & Limitations
For optimal results, always verify your input domain. Be aware that the SMTP verification process can be resource-intensive; if you are targeting large organizations, use the --no-verify flag or increase the --smtp-delay to ensure your IP remains off blacklists. Note that 'catch-all' server configurations may return 'deliverable' status for almost any email pattern, so treat those results with appropriate skepticism. The tool is designed for professional outreach and reconnaissance; always ensure your usage complies with local data protection regulations like GDPR or CAN-SPAM.
