What is Find Emails?
The Find Emails skill leverages the power of crawl4ai and Playwright to locally crawl websites and extract email addresses. It is specifically designed to target high-value pages such as Contact Us, About, and Support to find relevant contact information efficiently.
By providing a structured output grouped by domain, it simplifies the process of gathering leads or contact data for developers and researchers using Openclaw Skills. The tool focuses on local execution, ensuring privacy and control over the crawling process while delivering highly relevant results through smart URL pattern matching.
Find Emails Use Cases
- Automating lead generation by extracting emails from target company websites.
- Gathering contact information for outreach or recruitment from About Us or Team pages.
- Parsing local markdown files to extract email addresses without re-crawling.
- Conducting large-scale market research across multiple domains with consolidated reporting.
How Find Emails Works
- The user provides one or more target URLs or a local markdown file as input to the Openclaw Skills script.
- The skill utilizes crawl4ai to navigate the site, following links that match pre-defined patterns such as contact, about, or support.
- Email addresses are identified and extracted from the page content using regex and natural language processing filters.
- Results are normalized by domain to prevent duplicates and ensure clear attribution to the source website.
- The final output is generated in either a human-readable list or a structured JSON format for easy downstream processing.
Find Emails Setup
To get started with this skill, install the necessary Python dependencies and the Playwright browser engine:
pip install crawl4ai
playwright install
You can then run the script directly from your terminal:
python scripts/find_emails.py https://example.com
