Postscript is an SMS and MMS marketing platform built specifically for Shopify. It handles the text-message side of a store\u2019s marketing: collecting subscribers through popups and keywords, sending campaigns for launches and sales, and running automated flows like abandoned cart, welcome and back-in-stock, all segmented with your Shopify customer and order data. In our detection data it is one of the most-used SMS apps on Shopify, and the stores that run it are established, app-heavy brands rather than new shops. The verdict upfront: for a US store with real SMS volume, Postscript is a serious, capable choice, and it pairs naturally with an email tool. The honest catch is cost and reach. Pricing is usage-based with a monthly minimum, the bill climbs with every message, and the platform is built around US toll-free numbers and carrier rules.<\/p>\n

If you are a growing US brand that wants SMS as a genuine revenue channel alongside email, Postscript earns its place, and most of its stores run it next to Klaviyo<\/a> for exactly that split. If you are small, international, or just want email and SMS in one simpler tool, a combined platform like Omnisend<\/a> or Klaviyo\u2019s own SMS will cover you with less overhead. The sections below use live detection data to show how widely Postscript is used, what it does, what it costs, and the kind of store it fits.<\/p>\n

Key Takeaways<\/div>
1<\/div>
Postscript is a dedicated SMS and MMS marketing platform for Shopify, built for campaigns, automated flows and subscriber growth by text.<\/div><\/div>
2<\/div>
In our data it is a top-five SMS app, used about 3.1 times as often as the next tool, and it skews to established US DTC brands.<\/div><\/div>
3<\/div>
Almost every Postscript store also runs Klaviyo for email, so it is usually the SMS half of an email-plus-SMS stack, not an all-in-one.<\/div><\/div>
4<\/div>
Pricing is usage-based: free to install, then a monthly minimum plus a per-message rate and carrier fees, which gets expensive at volume.<\/div><\/div>
5<\/div>
Best for higher-volume US stores treating SMS as a real revenue channel; overkill and pricey for small or non-US shops.<\/div><\/div><\/div>\n

What is Postscript?<\/h2>\n

Postscript is an SMS and MMS marketing platform made for Shopify. It gives a store one place to build a text-message subscriber list, send broadcast campaigns, and run automated flows triggered by shopper behaviour. Because it is built for Shopify, it syncs customer and order data, so a message can be segmented and personalised rather than blasted to everyone. On the acquisition side it collects subscribers through popups, keywords and checkout opt-ins; on the sending side it handles campaigns, two-way conversations, compliance, and an AI layer that helps draft and target messages. It holds a 4.7 out of 5 rating from more than 1,200 reviews on the Shopify App Store. Here is how widely it is installed across our dataset.<\/p>\n
