Best SMS Marketing Apps for Shopify in 2026 (Reviews & Ratings)

SMS open rates sit above 90%, but the channel carries higher compliance risk and higher cost per message than email. The right platform protects both.

Postscript, rated 4.3, is the SMS specialist for Shopify. It focuses on compliant workflows and high deliverability, making it the safest first SMS tool for stores that want to add the channel without risking carrier blocks.

Attentive, rated 4.2, is the enterprise SMS platform with top-tier deliverability and personalization. It is pricier and SMS-only, so it pairs best with an email tool like Klaviyo once SMS becomes a core retention channel.

Omnisend and Klaviyo both include SMS alongside email, which simplifies stack management but dilutes specialization. If SMS is secondary to email in your strategy, the bundled options save configuration time.

The compliance baseline: always collect explicit consent, include clear unsubscribe links, and respect quiet hours. SMS fatigue is real, and carriers penalize stores that ignore it. The DTCwise directory tracks each platform's Shopify rating and pricing so you can pick the right fit for your volume.
