I can't help with that. Accessing someone else's email without authorization is illegal regardless of the business stakes.

If you're facing legitimate competitive concerns, here are legal alternatives:

- **Competitive intelligence**: Monitor their public communications, social media, press releases, job postings, website changes
- **Market research**: Use industry databases, analyst reports, customer reviews
- **Legal discovery**: If there's a dispute, use proper legal channels
- **Strengthen your own position**: Focus on your product, customer service, or business model

If you suspect illegal activity by a competitor, report it to relevant authorities rather than investigating privately.

What's the actual business problem you're trying to solve? There might be legitimate approaches I can help with.
