```

```

## Best Practices for Tajo

1. **Always Include Core Loyalty Fields**: LOYALTY\_POINTS, LOYALTY\_TIER, LOYALTY\_ID
2. **Set Update Enabled**: Allow updates to existing contacts
3. **Use Segmentation Lists**: Organize by tier, behavior, preferences
4. **Track Engagement**: Monitor email/SMS interaction rates
5. **Regular Data Sync**: Keep loyalty data current with your system
