Getting Started with SMS Marketing
- Choose a platform that supports both email and SMS (Brevo recommended)
- Register for 10DLC (required in the US for business SMS)
- Build your SMS list separately from email — SMS requires explicit SMS-specific consent
- Start with transactional messages (order confirmations, shipping updates) to establish trust
- Add promotional SMS gradually, limited to 2-4 per month
- Measure and optimize — track opt-out rates closely (keep under 2%)
