The Problem With Bolting SMS Onto Email
Almost every DTC brand that adds SMS starts the same way: they take their existing email flows, copy them to SMS, send both, and call it a cross-channel strategy. The result is predictable, subscribers receive the welcome email, then 30 minutes later an SMS saying the same thing, then a day later another email reminding them, then another SMS. The opt-out rates climb. The revenue per subscriber drops.
The fix isn't to send less. It's to orchestrate, to think of email and SMS as two tools with different strengths and use each where it wins.
The Strength-Based Channel Split
Email wins at
- Rich, long-form storytelling with images
- Product education and how-to content
- Discovery content (blog posts, UGC roundups)
- Non-time-sensitive revenue drivers
SMS wins at
- Time-sensitive announcements (flash sales, low-stock alerts, shipping updates)
- Urgency-dependent content (same-day cart recovery)
- VIP-tier communication (exclusive drops)
- Transactional confirmations
The orchestration principle: use each channel where it has the structural advantage. Avoid the default of sending the same content twice.
