How to Choose the Right SMS Use Cases First

  • Start with urgency: Prioritize flows where delayed messaging hurts conversion or service quality.
  • Map business outcomes: Tie each flow to an explicit KPI such as login success, repeat purchase, or no-show reduction.
  • Control message fatigue: Apply channel caps and frequency rules by user segment.
  • Optimize continuously: Review delivery and conversion weekly, then adjust timing and copy.
