This is a basic wrapper around SendGrid's mail service\n2. The SendGrid client is initialized as a singleton\n3. Only supports single recipient emails (no bulk sending)\n4. The `FROM` address is configured globally for all emails\n5. No template support - you must provide HTML and text content\n6. Limited error handling - errors are thrown directly from SendGrid\n\n## Limitations\n\n- No dynamic templates\n- No bulk email support\n- No personalization features\n- No advanced SendGrid features (tracking, scheduling, etc.)\n- Single sender address for all emails\n\nFor more advanced features, consider using the SendGrid API directly or extending this service.\n\n## License\n\nMIT","readmeFilename":"README.md"}
