Postscript vs Yotpo SMS: Which Email & SMS Software is Better for Shopify?
SMS and email marketing have become non-negotiable channels for Shopify merchants looking to drive revenue, recover abandoned carts, and build lasting customer relationships. Two platforms consistently rise to the top of the conversation: Postscript and Yotpo SMS (formerly SMSBump).
Both tools promise robust SMS capabilities purpose-built for Shopify, but they take meaningfully different approaches to features, pricing, and overall strategy. In this comparison, we’ll break down everything you need to know so you can make a confident decision for your store.

Yotpo SMS Overview
Yotpo SMS (formerly SMSBump) is the SMS and email marketing arm of the broader Yotpo ecommerce marketing platform. Acquired and rebranded, it now sits alongside Yotpo’s reviews, loyalty, subscriptions, and email products. For merchants already invested in the Yotpo ecosystem, SMS becomes significantly more powerful thanks to shared data across all modules.

| Feature | Postscript | Yotpo SMS |
|---|---|---|
| Platform Focus | SMS-first, Shopify-only specialist | Part of broader Yotpo ecosystem |
| Email Marketing | Available (newer feature) | Full-featured email builder |

| Free Plan | Yes (limited messages) | Yes (limited messages) |
Pricing Comparison
Both Postscript and Yotpo SMS use usage-based pricing models, meaning you pay based on the number of messages you send. Here’s a general pricing overview — note that rates may vary based on your plan and message volume.
| Pricing Aspect | Postscript | Yotpo SMS |
|---|---|---|
| Free Tier | Yes — includes basic features and limited message credits | Yes — includes basic features and limited message credits |
| Paid Plans Start At | ~$25/month + per-message costs | ~$19/month + per-message costs |
| SMS Cost (US) | ~$0.015–$0.025 per message | ~$0.015–$0.025 per message |
| MMS Cost (US) | ~$0.035–$0.045 per message | ~$0.030–$0.045 per message |
| Enterprise Plans | Custom pricing with volume discounts | Custom pricing, bundled Yotpo discounts |
Ease of Use
Postscript wins on simplicity. Because it’s built exclusively for Shopify and focused primarily on SMS, the interface is clean and intuitive. Merchants can set up their first campaign within minutes of installing the app. The automation flow builder uses a logical, linear structure that’s easy to understand even for beginners.
Yotpo SMS is also user-friendly, but the broader Yotpo platform can introduce a steeper learning curve. If you’re only using SMS, the interface may feel like it has more navigation options than you need. However, if you’re leveraging the full Yotpo suite, having everything in one dashboard becomes a genuine advantage.
Integrations & Ecosystem
Postscript integrates with a wide array of popular Shopify apps and marketing tools, including Klaviyo, Gorgias, ReCharge, Stamped, Privy, and more. Its open API also allows custom integrations for brands with development resources.
Yotpo SMS naturally integrates with the entire Yotpo product suite — Reviews, Loyalty & Referrals, Subscriptions, and Email. This creates a unified data layer where, for example, a loyalty milestone can trigger an SMS message, or a positive review can prompt a referral text. Outside the Yotpo ecosystem, it also integrates with major Shopify apps, though the deepest synergy happens within Yotpo’s own products.
Who Should Choose Postscript?
- Shopify-focused DTC brands that want the deepest possible SMS integration with their store
- Merchants prioritizing SMS as their primary marketing channel and who want best-in-class segmentation and deliverability
- Brands already using Klaviyo or another email platform that need a dedicated SMS tool to complement their existing stack
- Growing stores that want hands-on customer support and strategic SMS guidance
Who Should Choose Yotpo SMS?
- Brands already using Yotpo products (reviews, loyalty, subscriptions) that want a unified marketing platform
- International Shopify merchants who need SMS capabilities in 200+ countries
- Stores looking to consolidate tools and reduce the number of separate apps in their tech stack
- Merchants who want strong email and SMS in a single platform without adding a third-party email tool
Postscript Alternatives Worth Considering
While Postscript and Yotpo SMS are both excellent options, they’re not the only players in the space. Here are a few other Postscript alternatives worth evaluating:

- Omnisend: A budget-friendly omnichannel option that combines email, SMS, and push notifications in one platform.
