About
SMSBump
SMSBump was acquired by Yotpo in 2020 and now operates as its SMS product within the Yotpo ecosystem. For merchants already using Yotpo for reviews or loyalty, the integration unlocks review-triggered SMS flows and loyalty milestone messages without additional configuration. As a standalone SMS tool, it competes directly with Postscript and Attentive. The compliance tooling is thorough: opt-in flows, keyword responses (STOP, HELP, INFO), and carrier filtering are all handled automatically. The pricing model charges per message rather than per subscriber, which is predictable for low-volume brands but can scale steeply at high send frequencies. Stores that want to combine SMS with Yotpo reviews and loyalty data will get the most value from this platform.
Postscript
Postscript is the SMS marketing platform built exclusively for Shopify, which means the integration is native rather than bolted on. Subscriber segmentation pulls directly from Shopify order data, compliance is handled by default, and two-way conversational texting lets your support and sales team engage in real threads rather than broadcast blasts. The focus is narrow by design: if you also want email in the same tool, look at Klaviyo. But if SMS is your primary retention channel and you are on Shopify, Postscript is the most operator-friendly option in the market. Pricing scales with subscriber count, and the free tier is generous enough to validate the channel before committing.
