Is the data collection compliant with privacy laws?

The skill includes best practice guidelines for GDPR and CCPA compliance, such as respecting robots.txt, implementing rate limiting, and filtering out generic 'noreply' addresses.

Does this skill require paid API keys to work?

No, the skill is designed to work with free web scraping and pattern-guessing methods first. However, adding API keys for services like Hunter.io or Snov.io will significantly increase discovery depth and accuracy.

Can it verify if the found emails are actually valid?

Yes, it includes functionality to check MX records and utilize verification endpoints from supported APIs to ensure the discovered emails are deliverable.

How does the Email Finder skill discover email addresses?

It uses a multi-layered approach starting with free methods like scraping '/about' and '/contact' pages, checking WHOIS records, and guessing common patterns. It can then enrich these results using APIs like Hunter.io or Apollo if keys are provided.
