Standalone Lead Email Finder

A Python script to find potential email addresses associated with a company domain and optionally a specific contact name (like a CEO). It uses SearXNG for web searching and applies regex and filtering rules.

Features

• Finds potential email addresses from public web data.
• Accepts company name or domain/URL as primary input.
• Optionally accepts a CEO/contact name to refine search queries.
• Uses a SearXNG instance for web searches.
• Extracts emails from search result text content.
• Filters results against a blacklist of common/generic email providers (e.g., gmail.com, hunter.io).
• Optionally filters emails to match only the target company domain.
• Handles domain sanitization.
• Outputs results as a JSON list or a simple text list (one email per line).
• Standalone CLI Tool.
• Configurable logging level.

Prerequisites

1. Python: Python 3.7+ recommended.
2. Pip: Python package installer.
3. SearXNG Instance: Access to a running SearXNG instance and its base URL.
4. Libraries: requests (Install via requirements.txt).

Installation

1. Clone the repository or download the script:

2. git clone https://github.com/Aboodseada1/Email-Finder
   cd https://github.com/Aboodseada1/Email-Finder

3. Or simply download standalone_lead_email_finder.py and requirements.txt.
4. (Recommended) Create and activate a Python virtual environment:

5. python -m venv venv
   source venv/bin/activate # On Windows use `venv\Scripts\activate`

6. Install dependencies:

7. pip install -r requirements.txt

Usage

Run from your terminal:

python standalone_lead_email_finder.py <company_input> -s <searx_instance_url> [options]

Arguments:

• company_input: (Required) The company name (e.g., "Example Corp") or domain/URL (e.g., example.com).
• -s, --searx-url: (Required) The base URL of your SearXNG instance.
• -c, --ceo-name: (Optional) Full name of the CEO or contact person to focus the search.
• -o, --output-file: (Optional) Path to save the output file. If omitted, output goes to console.
• -f, --output-format: (Optional) Output format: json (full details) or txt (emails only, one per line). Default: json.
• -l, --log-level: (Optional) Set logging level: DEBUG, INFO, WARNING, ERROR, CRITICAL. Default: INFO.

Examples

(Replace placeholders)

# Find emails for a domain, output JSON to console
python standalone_lead_email_finder.py example.com -s http://localhost:8080

# Find emails for a company name and CEO, output JSON to file
python standalone_lead_email_finder.py "Acme Corp" -c "John Smith" -s https://searx.example.org -o acme_emails.json

# Find emails for a domain, output only emails to text file
python standalone_lead_email_finder.py microsoft.com -s http://localhost:8080 -f txt -o ms_emails.txt

# Run with debug logging
python standalone_lead_email_finder.py google.com -s http://localhost:8080 -l DEBUG

Output Format

JSON Format (-f json, default): Outputs a JSON object:

{
  "query_details": {
    "search_name": "used search name",
    "target_domain": "identified target domain or null"
  },
  "found_emails": [
    "[email protected]",
    "[email protected]"
  ],
  "error": "Error message if any, otherwise null"
}

TXT Format (-f txt): Outputs only the found, valid email addresses, each on a new line. If no emails are found, it outputs # No emails found. If an error occurred, it outputs Error: <error message>.

How It Works

1. Input Processing: Identifies if input is a domain/URL or company name; sanitizes domains.
2. Query Generation: Creates targeted SearXNG queries based on available info (domain, name, CEO name). Includes specific patterns like "ceo name" "domain" email and broader searches.
3. SearXNG Search: Fetches search results from the provided SearXNG instance for each query.
4. Extraction: Uses regex (EMAIL_REGEX) to find potential email addresses within the aggregated text content of search results.
5. Filtering: Removes emails from common/generic providers (BLACKLISTED_DOMAINS) and, importantly, filters to keep only emails matching the identified target_domain (if one was found).
6. Output: Returns the unique, filtered email addresses in the chosen format (JSON or TXT).

Limitations

• Relies entirely on data available through SearXNG search results.
• Accuracy depends on search engine indexing and website content.
• The EMAIL_REGEX is broad and might occasionally match non-email strings (though unlikely with the @ and . requirements).
• Filtering is based on the BLACKLISTED_DOMAINS list and matching the target domain; legitimate emails on other domains might be missed if filtering strictly by target domain.
• Does not verify if the found email addresses actually exist or are deliverable.
