export GOOGLE_CLIENT_ID="your-client-id"
export GOOGLE_CLIENT_SECRET="your-client-secret"
export GEMINI_API_KEY="your-gemini-key"

- Set follow-up reminders
- Archive processed items
Data Protection:
```typescript
// Redact sensitive information before AI processing
function redactSensitive(text: string): string {
return text
.replace(/\b\d{3}-\d{2}-\d{4}\b/g, '[SSN]')
.replace(/\b\d{16}\b/g, '[CARD]')
.replace(/password:\s*\S+/gi, 'password: [REDACTED]');
}
// Use local processing for sensitive emails
async function processEmail(email: Email) {
if (email.labels.includes('CONFIDENTIAL')) {
return processLocally(email);
}
return processWithAI(email);
}
```
❌ Over-automation: Don't auto-send replies without review
❌ Ignoring context: AI needs email history for accurate classification
❌ Poor training: Correct AI mistakes to improve accuracy
❌ No fallback: Always have manual override options
❌ Privacy leaks: Never send confidential data to external APIs
AI email management in 2026 is mature, accurate, and essential for productivity. Start with Gmail + Gemini for simplicity, or build custom with Claude API for maximum control.
