What Is Tempmail and How Does It Work?
Tempmail (temporary mail) is a disposable email address generated instantly—no signup, password, or personal data required.
How it works:
- A random email address is generated on demand
- Incoming emails are received on a public or semi-private inbox
- The inbox auto-expires after a fixed time or manual deletion
- Messages are permanently erased from the server

Why Tempmail Matters More in 2026 (AI & Privacy Context)
1. Protection Against AI-Driven Phishing
Modern phishing attacks use AI models trained on breached email data. Using a temporary email:
- Breaks cross-platform identity linking
- Prevents inbox fingerprinting
- Limits exposure to credential-stuffing campaigns
2. Reduced Data Brokerage Tracking
Marketing AI systems track:
- Signup → email → device → behavior
Tempmail disrupts this chain at the first data-collection point.
