SMS Marketing for Shopify Stores in 2026

SMS marketing has a 98% open rate and an average response time of 90 seconds. No other channel comes close. For Shopify brands that have invested in building a text subscriber list, SMS is consistently one of the highest-ROI channels in the marketing mix — when it's done right.

Choosing Your SMS Platform

For Shopify stores, the main SMS platforms to consider are Klaviyo (if you already use it for email), Attentive, Postscript, and SMSBump (by Yotpo). Each has strengths:

• Klaviyo: best for brands already on Klaviyo — unified email + SMS flows and segments, single platform
• Attentive: market leader for large-scale SMS, excellent compliance tools, higher price point
• Postscript: Shopify-native, strong automation features, competitive pricing
• SMSBump: good for brands in the Yotpo ecosystem, integrates well with Yotpo Reviews and Loyalty

Compliance: The Non-Negotiable

SMS compliance is significantly more regulated than email. In the UK, you need explicit opt-in consent for marketing texts — pre-ticked boxes or bundled consent within terms and conditions are not sufficient. PECR (Privacy and Electronic Communications Regulations) governs SMS marketing in the UK.

The SMS Flows That Drive Results

SMS works best as a complement to email, not a replacement. The highest-performing flows use SMS strategically for high-urgency or high-value moments:

1. 1Abandoned cart SMS: sent 1-2 hours after cart abandonment — typically achieves 10-20% recovery rate
2. 2Flash sale alerts: 'Live now — 24 hours only' texts drive immediate traffic spikes
3. 3Back-in-stock alerts: customers who opted in to be notified convert at extremely high rates
4. 4VIP early access: give your best customers first access to new collections via SMS
5. 5Order shipping updates: transactional SMS builds trust and reduces support tickets

SMS Best Practices

• Keep messages under 160 characters to avoid splitting into multiple SMS segments
• Always include your brand name at the start — recipients need to know who's messaging them
• Include a clear opt-out instruction (e.g., 'Reply STOP to unsubscribe') in every marketing text
• Send between 10am and 8pm in the recipient's local timezone
• Limit to 2-4 marketing texts per month — frequency is where most brands damage their SMS list
• Use personalisation tokens (first name, product name) where available

“SMS is not email. The intimacy of the channel means every message has to earn its place. Brands that treat their SMS list with respect build audiences that stay subscribed for years.”
