What iris checks
- Email authentication - DKIM, SPF, DMARC verification
- Domain impersonation - homoglyph detection (e.g. "paypa1.com" mimicking "paypal.com")
- URL shorteners - links that hide the real destination (bit.ly, tinyurl, etc.)
- Pressure language - urgency tactics ("Act now", "account suspended")
- Credential requests - emails asking for your password
- Generic greetings - "Dear Customer" instead of your name
- Display name spoofing - sender name doesn't match the actual email address
- Suspicious attachments - potentially dangerous file types
