# Postscript

> SMS and RCS marketing for Shopify stores, billed per message sent

Postscript is a text message marketing platform built around Shopify stores. It sends SMS, MMS and RCS campaigns and automated flows such as cart and browse abandonment, grows the list with popups and checkout opt-ins, and segments subscribers on Shopify order data. Plans set a monthly platform fee and a per-message rate, and email is opening through a waitlist.

## ToolGPA grades

**GPA: 2.2 out of 4**, graded Oct 18, 2026. Postscript is text marketing built around Shopify: campaigns, cart and browse abandonment flows, popups and segments built on order data. Starter has no platform fee, just a $49 monthly minimum spend on messages at $0.009 per SMS. It's a neat fit for a Shopify store, and an awkward one for anyone else.

- **Value for money: C.** Starter has no platform fee, just a $49 monthly minimum spend. Texting 1,000 customers once at $0.009 per SMS stays inside that minimum, so $49 is the figure, plus US carrier fees averaging $0.0033 per SMS. That's the dear end of ordinary for this category.
- **Free plan and trial: C.** No free plan, but a free trial with a $100 credit toward message and carrier fees for your first 30 days. That's a decent run at a first campaign.
- **Features: C.** The texting job done fully for a Shopify store: campaigns, cart and browse abandonment flows, popups, two-way replies and segments built on order data. But texting is one channel of this category, RCS waits for Enterprise and email is still a waitlist.
- **Ease of use: C.** No App Store rating on record. It plugs into Shopify, but you still set up opt-in popups, keywords and flows before the first text goes out.
- **Platforms and integrations: B.** Runs on the web, with Shopify, Klaviyo, Gorgias, Zendesk, Kustomer, Mailchimp, Omnisend and Triple Whale. API access waits for Professional at $500 a month, and there's no app.

## Keep it, or make your own?

**Keep it.** To replace Postscript you would be making texts to thousands of numbers, registered with the carriers. That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 6 of the 14 other SMS and chat marketing tools grade higher. It costs $588 a year.

- You could make: Popups: an app builder makes this well.
- You could not: Texts to thousands of numbers, registered with the carriers.
- You could not: Email sent in volume that still reaches the inbox.
- You could not: It plugs into other products, Shopify, Klaviyo and Gorgias among them, and has an API.
- You could not: AI features, unless you pay a model provider for each request yourself.
