Postscript Review: How to Make Money as an Affiliate

What Is Postscript?
Postscript is a text message marketing platform built for Shopify stores. It helps online brands collect phone numbers, send SMS campaigns, and set up automated texts like abandoned cart reminders.
Lately it has grown beyond plain SMS. Postscript now calls itself an AI retention marketing platform, with SMS, RCS (branded rich messages), and email on the way.
In plain English? It's a tool that helps a store sell more to people who already know it.
Here's what you get:
- SMS and MMS campaigns sent to your subscriber list
- Automations built in a visual flow builder, with ready-made templates
- List growth tools like onsite opt-in pop-ups and keywords
- Segmentation so you can text the right people, not everyone
- Compliance guardrails to help you stay on the right side of texting rules
- AI features such as Brand Center, Infinity Testing, and Shopper (1:1 journeys)
- Postscript Plus, an optional service where their strategists run your SMS program for you
How Does Postscript Work?

Who Should Use Postscript?
Users
Postscript is a good fit for Shopify store owners who want texting to be a real sales channel. If you already have traffic and some repeat buyers, SMS can bring them back.
It's less of a fit if you aren't on Shopify, or if you just want one cheap tool for email and a few texts. Then an all-in-one email tool might be simpler.
Affiliates
This program makes the most sense for people who already talk to ecommerce owners. Think Shopify bloggers, YouTubers, agencies, and app reviewers.
If your audience is bloggers or coaches, Postscript probably isn't your best offer. If your audience runs stores, it could be a great one.
Pros and Cons of Postscript
Pros
- Built for Shopify, so setup is focused and simple
- Free trial on self-serve plans
- Low entry point with the Starter plan
- Clear, published per-message rates
- Strong automation and segmentation tools
- Optional done-for-you help with Postscript Plus
Cons
- Shopify only, which limits who can use it
- Costs grow with your sending volume, and carrier fees come on top
- Jumps between plans are big ($100 to $500 a month)
- Email isn't fully launched yet (there's a waitlist)
- No refunds on subscription payments already processed
- For affiliates, the commission rate isn't published on the public partner page
Postscript vs Alternatives
| Tool | Main Focus | Starting Price | Shopify Focus |
|---|---|---|---|

If you want email and SMS in one cheaper tool, read my Brevo review and my Sender review.
If your customers live in Instagram DMs, my Manychat review covers that side of things.
How to Make Money with Postscript as an Affiliate
The Commission
Here's the honest truth. Postscript's partner page says you "earn revenue from every customer you refer," with automatic commission payments through a partner dashboard. But it does not publish the commission rate, how long it lasts, the cookie length, or the payout schedule.
- Network: PartnerStack (the application form is hosted there)
- Commission rate: not published. Check their site or your partner dashboard after approval.
- Duration and cookie: not published. Check their site.
- Tiers: Silver (refer 1 paying customer), Gold ($15,000 in rolling 12-month referred MRR), Platinum ($50,000 in rolling 12-month referred MRR)
- Who it's for: agencies, developers, app developers, ecommerce influencers, and investors
- Extras: free certification, a branded referral link, and a spot in the Partner Directory at Gold and above
So apply, get approved, and confirm the terms before you build a lot of content around it. That's just smart.

Final Thoughts
Postscript is a focused, well-built SMS tool for Shopify brands. It's not for everyone. But for store owners who want texting to drive repeat sales, it's a serious option.
For affiliates, it's the same story. If your audience runs Shopify stores, Postscript is worth applying to. Just confirm the commission terms first, since they aren't public.
