The short answer

Both sides assessed

Postscript compared with SimpleTexting

SimpleTexting is a general business texting platform with credit-based plans from $39 a month, a shared inbox, and 1,000-plus Zapier integrations; it will happily serve a dentist, a gym, or a store. Postscript does one thing and does it far deeper, with ecommerce triggers, revenue attribution, and Shopify-native segments that SimpleTexting cannot approach. Pick SimpleTexting if texting is a customer-communication channel across your business. Pick Postscript if texting is a revenue channel attached to a Shopify cart.

SimpleTexting compared with Postscript

Postscript is Shopify-only, with native ecommerce triggers, revenue attribution, and per-message pricing that beats credit plans badly at volume. SimpleTexting is cart-agnostic and useless for commerce data. A Shopify store should be on Postscript. A dentist, a gym, a school district, or a staffing agency should be on SimpleTexting, where the shared inbox and rolling credits are actually the point.

Choose Postscript if

Shopify and Shopify Plus merchants doing enough revenue that a dedicated SMS channel earns its keep, particularly stores with repeat purchase behavior, subscriptions on Recharge, or a Klaviyo email program already running that they want SMS to sit alongside rather than replace.

Choose SimpleTexting if

Small and mid-sized US and Canadian businesses that want a straightforward, well-supported texting platform for appointment reminders, promotions, alerts, and two-way customer conversations, especially teams of three to five who value rolling credits and included seats over ecommerce or CRM depth.

Setup time	The app installs and connects to Shopify in under an hour, but you cannot send until carrier registration clears. Toll-free verification typically takes one to three weeks, A2P 10DLC brand and campaign registration usually one to four weeks, and a dedicated short code eight to twelve weeks. Plan on two to four weeks from install to first campaign, and start registration on day one.	An account and a local number can be live the same day. Realistically you are gated by carrier registration: A2P 10DLC brand and campaign approval takes roughly one to four weeks, toll-free verification up to a week, and a short code six to eight weeks. Start registration immediately and build lists while you wait.
Learning curve	Low for campaigns, moderate for automations. The flow builder is approachable but the value sits in the 45 segment filters and 85 trigger filters, and getting real leverage from those means understanding your own Shopify data well enough to know which ones matter. Most merchants get abandoned checkout and welcome flows live in week one and spend a quarter learning the rest.	Genuinely low. The interface is the plainest in this category and a non-technical front-desk employee can send a campaign in fifteen minutes. Drip campaigns and segmentation take an afternoon. The only conceptual hurdle is credit accounting, and specifically the fact that an emoji can double or triple the cost of a message.

Strengths and limitations

Postscript

Strengths

Shopify-native data model means segments and triggers read order history, line items, discounts, and subscription state directly, with no field mapping and no sync lag to debug.
Compliance is a product feature rather than a disclaimer: quiet hours by recipient time zone are the default, an in-house legal team tracks rule changes, and consent records are stored per subscriber with source and timestamp.
Subscriber collection is unusually deep, and the Onsite Opt-in Network genuinely lifts opt-in rates on stores with no existing list because it recognizes shoppers already in Postscript's base.
Pricing tiers buy a lower per-message rate rather than gating features, so the cost model is transparent arithmetic you can run before signing up.

Limitations

Shopify only. There is no path for WooCommerce, BigCommerce, Magento, or headless commerce, and replatforming means replacing Postscript.
No email channel, so you run it beside Klaviyo, Kit, or similar and reconcile attribution across two systems with different windows.
API access is gated to the $500 Professional tier, which pushes developer-led merchants into a price bracket they may not otherwise need.
The $49 minimum spend on Starter means the entry price is not actually zero, and the platform-fee tiers only pay for themselves at meaningful volume.

SimpleTexting

Strengths

Credits roll over on monthly plans, so a business with a lumpy sending pattern does not forfeit what it paid for at the end of every month.
Three user seats included on every plan before the $20 per seat charge starts, which is more generous than most competitors and matters for a front desk with rotating staff.
Free inbound SMS makes genuinely two-way conversation economically viable rather than something you ration.
Features are not gated by tier. You buy volume, not capability, which means plan selection is arithmetic instead of a feature-matrix negotiation.

Limitations

Per-credit economics are poor at volume. At entry pricing you are paying multiples of what per-message platforms charge, and the 5.5 cent overage rate punishes miscalculation.
No ecommerce data model at all, so revenue attribution, cart triggers, and product-level personalization simply do not exist.
CRM integration runs mostly through Zapier rather than native object sync, which is a meaningful gap next to Salesmsg or Sakari for a sales team.
Number porting away has been publicly documented as slow and obstructive, in one case requiring an FCC complaint and taking three weeks. That is a real switching cost you should price in before choosing a number.

Pricing compared

Postscript

Monthly platform fee that buys a lower per-message rate, plus usage. Carrier pass-through fees apply on top of every message on every tier. No per-seat charge and no credit bundles.

Starter$0
Growth$100
Professional$500
EnterpriseCustom

Postscript is priced for stores where SMS is a real revenue line, not an experiment. On Growth at $100 plus roughly $0.013 all-in per SMS segment, a 25,000-message month costs about $425, which is defensible if attribution shows the channel returning multiples of that and indefensible if it does not. The genuinely good part of the structure is that the platform fee buys a rate reduction rather than a feature unlock, so the decision is arithmetic rather than a negotiation. The bad part is API access sitting behind the $500 Professional tier, which is a strange gate for a platform whose whole pitch is data-native integration. Against general-purpose texting tools charging per credit, Postscript looks expensive at low volume and clearly cheaper at high volume, which is exactly what you would expect from a platform built for stores that send a lot.

SimpleTexting

Credit-based monthly subscription, quoted by monthly credit volume. Credits are consumed per message segment. Three user seats included, additional seats and numbers charged separately, carrier fees passed through at cost.

500 credits$39
Higher credit tiersScales with volume
Annual billing20 percent off

SimpleTexting is priced as a business tool rather than a telecom commodity, and whether that is good value depends entirely on volume. At 500 credits for $39, you are paying roughly 7.8 cents a credit, which is five times what a pay-as-you-go platform charges per message and eight times what an ecommerce platform charges at scale. What you are actually buying is the shared inbox, three included seats, the automation layer, the support, and the fact that unused credits roll over. For a practice or a studio sending a few hundred reminders a month and holding real conversations, that is a fair trade and the total bill stays under $50. For anyone sending tens of thousands of messages, the credit model becomes the most expensive way to buy SMS in this category and you should be looking at per-message pricing instead. The rollover policy and the three included seats are the two structural details that make it competitive at the small end, and they are genuinely better than most rivals offer.

Editorial verdict on each

Postscript

Category Leader

Postscript is the strongest SMS platform in the Shopify ecosystem and it is not close, provided you are actually on Shopify and actually sending enough to justify the structure. The native data model, the depth of the segment and trigger filters, the quality of the subscriber collection tooling, and the fact that quiet hours and consent records are defaults rather than settings all reflect a team that has thought about this problem for eight years. The pricing is honest arithmetic: a platform fee that buys a lower per-message rate, with carrier fees disclosed rather than hidden. The reasons to look elsewhere are structural rather than qualitative. You cannot use it off Shopify, it does not send email, API access sits behind a $500 tier, and the $49 minimum spend means a small store is subsidizing capacity it will never use. If you run a Shopify store where SMS is a revenue line rather than an experiment, start here. If you run anything else, this product is not for you and no amount of feature depth changes that.

SimpleTexting

SimpleTexting is the sensible default for a small business that wants to text customers and has no interest in becoming a telecom expert. Fifteen years in market, a clean interface a receptionist can use unaided, phone support on every plan, three seats included, free inbound messages, and credits that actually roll over add up to a product that does not fight you. Sinch ownership gives it real carrier infrastructure without an enterprise sales motion. The limits are equally clear. Per-credit economics are poor at volume, there is no ecommerce data model, CRM integration is Zapier-shaped rather than native, and the publicly documented difficulty of porting a number away is a genuine switching cost that deserves weight in the decision. Buy it if you are a practice, a studio, a school, an agency, or a local retailer sending hundreds to low thousands of messages a month with a small team working the replies. Look elsewhere if you are a Shopify store, a CRM-driven sales team, or a high-volume sender chasing the lowest rate per segment.
