SMS Marketing (DTC)
Quick definition
Direct text messaging to opted-in subscribers. Higher conversion than email per send, with higher cost per send and tighter compliance.
What it actually means
SMS converts higher per send than email for eCommerce, at a higher cost per send. Best use cases: cart abandonment, product drops, back-in-stock alerts, VIP exclusive offers. Compliance is critical: TCPA in the US, PECR in the UK, GDPR in the EU. Subscribers must give explicit consent before any send. Sending unsolicited SMS is a fast path to lawsuits and carrier blocks.
