📊 Usage Limits & Recommendations

⚠️ IMPORTANT: Free tiers are limited for email processing due to large text content.

Provider	Free Limit	Recommendation
Gemini	20 emails/day per API key	⭐ Create multiple keys in different projects
Groq	20-30 emails/day	⭐ Best free tier overall
Claude	10-15 emails/day	Good for privacy-conscious users
OpenAI	5-10 emails/day	Consider paid plan ($5-20/mo)

💡 Tips for Managing Free Tier Limits

For Gemini users (NEW in v1.2.1!):

• 🆕 Multiple API Keys: Add keys from different Google Cloud projects
• 🔄 Automatic Rotation: Extension switches keys when limits are reached
• 📊 Per-Key Tracking: Monitor usage for each key independently
• ✨ Example: 5 keys = 100 requests/day total (20 per key)
• 🔧 How to add: Settings → Add Another Gemini Key
• Check usage: AI Studio Usage

For all providers:

• Process emails in small batches
• Use "Gemini paid plan" checkbox to disable limits (if you have paid tier)
• Consider paid plans for daily use ($5-20/month)

⚠️ Troubleshooting

🔧 Settings Page Won't Load

1. Thunderbird → Settings → Privacy → Cookies and Site Data
2. Click "Clear Data"
3. Tools → Add-ons → AutoSort+ → Reload

🔑 API Key Not Working

• Verify key is copied correctly (no spaces)
• Click "Test API Connection" button
• Check key is from correct provider
• Ensure API key has proper permissions
• For Gemini: Check usage page

❌ Email Analysis Fails

Check:

• ✓ Internet connection active
• ✓ API key is valid
• ✓ Provider status page for outages
• ✓ Rate limits not exceeded
• ✓ Email content isn't empty

For Gemini users:

• Check usage counter in settings
• Verify daily limit not reached (20/day)
• Switch to new API key if needed

📁 Wrong Labels Applied

• Ensure labels are case-sensitive matches
• Avoid special characters in folder names
• Verify labels are saved (green checkmark)
• Check move history for patterns

⏱️ Rate Limit Errors

Gemini (20/day per key):

• Create new API key in different project
• Reset counter after switching keys
• Enable "paid plan" option if you have one

Other Providers:

• Wait for rate limit window to reset
• Consider upgrading to paid tier
• Use provider's usage dashboard

📋 System Requirements

Component	Requirement
Thunderbird	78.0 or later
Internet	Active connection for API calls
API Key	Valid key from chosen provider
