Who uses Postscript SMS Marketing?

The typical Postscript store is a focused, growth-stage brand. Its median catalog is 24 products and it runs 8 detected apps. That is a smaller catalog than Klaviyo stores (median 50 products) or Omnisend stores (57), and it fits the kind of brand that texts well: a few core products, a loyal customer base and frequent launches or restocks to announce.

Postscript also leans toward larger merchants. About 11.1% of its stores run Shopify Plus, about two and a half times the Shopify-wide rate. That is above Omnisend (about 7.2%) and a little below Klaviyo (about 14.5%). For a dedicated SMS tool with a $100 entry price on paid plans, that is the expected profile: brands with enough revenue for text marketing to pay back, often already running Klaviyo or another email platform alongside it.

Postscript is overwhelmingly a US app. About 83% of its stores are in the United States, and only 17% are elsewhere. Canada follows at about 5%, the United Kingdom at about 3%, Australia at about 2%, and Germany and the Netherlands at about 1% each. Compare Klaviyo, where 59% of stores are outside the US, and Omnisend at 61%.

That concentration reflects how SMS marketing works. Text marketing rules, carrier registration and consumer habits differ by country, and US shoppers are used to brand text messages in a way that many other markets are not. A dedicated US-focused platform is a natural fit for US brands and less so for stores selling mainly in Europe or Asia.

By category, fashion leads at 26% of stores, followed by business and industrial at about 23%. Food and drink accounts for about 9.5%, general shopping for about 7% and technology for about 6%. Fashion and food are classic SMS categories, where drops, restocks and limited offers give a brand a reason to text.

The apps that show up next to Postscript describe a sophisticated US direct-to-consumer brand. Intelligems, an A/B price and offer testing app, shows up 10.5x more often than on the average Shopify store. Route, which offers shipping protection and tracking, appears 10.1x more often, and Redo, a returns and exchanges platform, 9.3x more often. Wyllo leads the list at 11.7x.

ABC Store Analytics shows up 6.6x more often and Rise, a gift card and store credit app, 5.4x more often. Price testing, shipping protection, returns that keep revenue in store credit and dedicated analytics all point to brands that measure carefully and invest in the post-purchase experience.

For anyone selling to Shopify brands, a Postscript install is a strong marker of a US brand with a marketing team, a testing culture and a budget for premium tools.

Postscript vs Klaviyo

Klaviyo is a widely used email platform on Shopify, rated 4.7 across 3,370 reviews, and it also sells SMS, with a free plan and paid SMS and email plans from $15 and $20 a month. Klaviyo stores are larger (median 50 products), more international (59% outside the US) and slightly more often on Plus (about 14.5%). Its critical reviews mention limited support (28%), complexity (23%) and pricing and plan increases (22%). Many brands run Klaviyo for email and Postscript for SMS. Choose Klaviyo if you want email and SMS in one place, Postscript if SMS is a core channel and you want a specialist.

Postscript vs Omnisend

Omnisend is rated 4.7 across 3,188 reviews, with a free plan and paid plans at $16 and $59 a month, and it bundles email and SMS. Omnisend stores are more international (61% outside the US) and less often on Plus (about 7.2%). Its critical reviews lead with slow support (41%). Omnisend suits stores that want low-cost email and SMS in one tool, especially outside the US.

Smaller SMS and messaging apps in the category include CW, a WhatsApp, SMS and AI chatbot tool (246 App Store reviews), Emotive (94), YSMS (66), YipSMS (26), Notify Customers SMS Marketing (23) and HiTide (21). They tend to suit smaller stores or messaging channels beyond SMS.
