Perfect for email automation and workflows. homepage: https://github.com/briansmith80/clawdbot-zoho-email --- # Zoho Email Integration **v2.0** - Complete Zoho Mail integration with OAuth2 authentication and REST API backend (5-10x faster than IMAP/SMTP). Supports HTML emails, attachments, batch operations, and advanced automation workflows. Choose your authentication: OAuth2 (recommended, secure) or app password (simple setup). ## ✨ Features ### 🔐 Authentication & Performance - **OAuth2 authentication** - Secure token-based auth with automatic refresh - **REST API backend** - 5-10x faster operations than IMAP/SMTP - **Graceful fallback** - Automatically falls back to IMAP if REST API unavailable - **App password support** - Simple alternative to OAuth2 ### 📧 Email Operations - **📥 Read emails** - Fetch from any folder (Inbox, Sent, Drafts, etc.) - **🔍 Smart search** - Search by subject, sender, keywords with REST API speed - **📊 Monitor inbox** - Real-time unread count for notifications - **📤 Send emails** - Plain text or HTML with CC/BCC support - **🎨 HTML emails** - Rich formatting with professional templates included - **📎 Attachments** - Send and download file attachments ### ⚡ Batch & Bulk Operations - **Batch operations** - Mark, delete, or move multiple emails efficiently - **Bulk actions** - Search and act on hundreds of emails at once - **Dry-run mode** - Preview actions before executing for safety ### 🔒 Security - **No hardcoded credentials** - OAuth2 tokens or environment variables only - **Automatic token refresh** - Seamless token renewal - **Encrypted connections** - SSL/TLS for all operations ## 📦 Installation ```bash clawdhub install zoho-email ``` **Requirements:** - Python 3.x - `requests` library (install: `pip3 install requests`) - Zoho Mail account ## ⚙️ Setup ### 1. Get an App-Specific Password **Important:** Don't use your main Zoho password! 1. Log in to Zoho Mail 2. Go to **Settings** → **Security** → **App Passwords** 3. Generate a new app password for "Clawdbot" or "IMAP/SMTP Access" 4. Copy the password (you'll need it next) ### 2. Configure Credentials **Option A: Environment Variables** Export your Zoho credentials: ```bash export ZOHO_EMAIL="your-email@domain.com" export ZOHO_PASSWORD="your-app-specific-password" ``` **Option B: Credentials File** Create `~/.clawdbot/zoho-credentials.sh`: ```bash #!/bin/bash export ZOHO_EMAIL="your-email@domain.com" export ZOHO_PASSWORD="your-app-specific-password" ``` Make it executable and secure: ```bash chmod 600 ~/.clawdbot/zoho-credentials.sh ``` Then source it before running: ```bash source ~/.clawdbot/zoho-credentials.sh ``` ### 3. Test Connection ```bash python3 scripts/zoho-email.py unread ``` Expected output: ```json {"unread_count": 5} ``` ## 🚀 Usage All commands require credentials set via environment variables. ### Quick commands (common tasks) ```bash # Diagnose setup (recommended first step) python3 scripts/zoho-email.py doctor # Unread count (great for briefings) python3 scripts/zoho-email.py unread # Search inbox python3 scripts/zoho-email.py search "invoice" # Get a specific email (folder + id) python3 scripts/zoho-email.py get INBOX # Send a simple email python3 scripts/zoho-email.py send recipient@example.com "Subject" "Body text" # Empty Spam (safe by default: DRY RUN) python3 scripts/zoho-email.py empty-spam # Execute for real python3 scripts/zoho-email.py empty-spam --execute # Empty Trash (safe by default: DRY RUN) python3 scripts/zoho-email.py empty-trash # Execute for real python3 scripts/zoho-email.py empty-trash --execute ``` ### Send HTML Emails Send rich, formatted HTML emails with multipart/alternative support (both HTML and plain text versions): **CLI Command:** ```bash # Send HTML from a file python3 scripts/zoho-email.py send-html recipient@example.com "Newsletter" examples/templates/newsletter.html # Send HTML from inline text python3 scripts/zoho-email.py send-html recipient@example.com "Welcome" "

Run: ```bash export ZOHO_EMAIL="your-email@domain.com" export ZOHO_PASSWORD="your-app-password" ``` ## 🛣️ Roadmap ### ✅ Completed (v2.0.0) - [x] **OAuth2 authentication** - Secure token-based auth with auto-refresh - [x] **Zoho Mail REST API** - 5-10x faster than IMAP/SMTP - [x] **Attachment support** - Download and send attachments - [x] **HTML email composition** - Rich formatting with templates - [x] **Batch operations** - Mark, delete, move multiple emails - [x] **Bulk actions** - Search and act on many emails at once ### 🔮 Future Enhancements - [ ] **Email threading/conversations** - Group related emails together - [ ] **Label management** - Create and manage Zoho Mail labels - [ ] **Draft email management** - Create, edit, and send drafts - [ ] **Scheduled sends** - Schedule emails to send later - [ ] **Email templates** - Reusable email templates with variables - [ ] **Webhooks** - Real-time notifications for new emails - [ ] **Advanced search** - Filter by size, has-attachment, date ranges - [ ] **Zoho Calendar integration** - Create events from emails - [ ] **Zoho CRM integration** - Sync contacts and activities ## 📝 Notes - **Search limit:** Returns last 5-10 emails by default (configurable in code) - **Body truncation:** Search results show first 500 characters - **Encoding:** Handles UTF-8 and various email encodings - **Security:** Credentials never leave your system except to Zoho servers ## 🤝 Contributing Found a bug or want to contribute? Submit issues or PRs on GitHub! ## 📄 License MIT License - free to use, modify, and distribute. --- **Created:** 2026-01-29 **Status:** Production-ready ✅ **Requires:** Python 3.x. For REST API mode: `pip install -r requirements.txt` (includes `requests`). ## 🔄 Batch Operations New in v1.1! Process multiple emails efficiently with batch commands. ### Mark Multiple Emails as Read ```bash python3 scripts/zoho-email.py mark-read INBOX 1001 1002 1003 ``` Mark several emails as read in one command. Perfect for clearing notifications. ### Mark Multiple Emails as Unread ```bash python3 scripts/zoho-email.py mark-unread INBOX 1004 1005 ``` Flag important emails to revisit later. ### Delete Multiple Emails ```bash python3 scripts/zoho-email.py delete INBOX 2001 2002 2003 ``` **Safety:** Asks for confirmation before deleting. Emails are moved to Trash (not permanently deleted). ### Move Emails Between Folders ```bash python3 scripts/zoho-email.py move INBOX "Archive/2024" 3001 3002 3003 ``` Organize emails by moving them to custom folders. ### Bulk Actions with Search Perform actions on all emails matching a search query: ```bash # Dry run first - see what would be affected python3 scripts/zoho-email.py bulk-action \ --folder INBOX \ --search 'SUBJECT "newsletter"' \ --action mark-read \ --dry-run # Execute the action python3 scripts/zoho-email.py bulk-action \ --folder INBOX \ --search 'SUBJECT "newsletter"' \ --action mark-read ``` **Available actions:** - `mark-read` - Mark all matching emails as read - `mark-unread` - Mark all matching emails as unread - `delete` - Move all matching emails to Trash **Search query examples:** ```bash # By subject --search 'SUBJECT "invoice"' # By sender --search 'FROM "sender@example.com"' # Unread emails --search 'UNSEEN' # Combine criteria (AND) --search '(SUBJECT "urgent" FROM "boss@company.com")' # Date range --search 'SINCE 01-Jan-2024' ``` ### Batch Operations in Python ```python from scripts.zoho_email import ZohoEmail zoho = ZohoEmail() # Mark multiple emails as read result = zoho.mark_as_read(['1001', '1002', '1003'], folder="INBOX") print(f"Success: {len(result['success'])}, Failed: {len(result['failed'])}") # Delete multiple emails result = zoho.delete_emails(['2001', '2002'], folder="INBOX") # Move emails to another folder result = zoho.move_emails( email_ids=['3001', '3002'], target_folder="Archive/2024", source_folder="INBOX" ) # Bulk action with search result = zoho.bulk_action( query='SUBJECT "newsletter"', action='mark-read', folder="INBOX", dry_run=True # Preview first ) print(f"Found {result['total_found']} emails") print(f"Will process {result['to_process']} emails") # Execute for real result = zoho.bulk_action( query='SUBJECT "newsletter"', action='mark-read', folder="INBOX", dry_run=False ) ``` ### Batch Cleanup Example Clean up old newsletters automatically: ```bash # 1. Preview what will be deleted python3 scripts/zoho-email.py bulk-action \ --folder INBOX \ --search 'SUBJECT "newsletter"' \ --action delete \ --dry-run # 2. Review the preview output # 3. Execute if satisfied python3 scripts/zoho-email.py bulk-action \ --folder INBOX \ --search 'SUBJECT "newsletter"' \ --action delete ``` See `examples/batch-cleanup.py` for a complete automated cleanup script.
