- Add MongoDB connection module for database access - Implement Mailgun email service for sending notifications - Add shareChecksum utility for generating secure share links - Implement three email sender functions: - Email verification requests (highest priority) - Rent due notifications (CET timezone) - Utility bills due notifications - Create main email worker with budget-based email sending - Add environment variables for configuration - Install dependencies: mongodb, mailgun.js, form-data - Update package.json description to reflect email worker purpose - Add .env.example with all required configuration The worker processes emails in priority order and respects a configurable budget to prevent overwhelming the mail server. All database operations are atomic and updates are performed immediately after each email send. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
