SMS is the highest-ROI channel for DTC
SMS open rates run 90%+. Click rates run 4-8%. Conversion rates often rival or exceed email despite list sizes 10-20% the size. Cost per send is meaningful ($0.01-$0.02), so frequency must be deliberate. The best DTC programs send 4-8 SMS per month and grow lifetime value 30-50% over email-only programs.
