Postscript has become the default choice for many Shopify stores looking to add SMS marketing.
But default doesn't always mean best.
As your store grows, you might find yourself bumping against Postscript's limitations: pricing that scales faster than your revenue, features that feel built for everyone instead of your specific needs, or support that leaves you waiting when you need help now.
The good news? You have options. The SMS marketing landscape has exploded with alternatives that cater to different store sizes, budgets, and strategies.
Some double down on AI-powered conversations. Others bundle SMS with email, reviews, and loyalty programs.
A few strip away complexity to focus purely on reliable message delivery.
This guide breaks down seven Postscript alternatives worth considering in 2026.
Each one serves a different type of store, and by the end, you'll know which fits your situation best.

What makes a great Postscript alternative?
Before diving into the options, let's establish what separates the good alternatives from the mediocre ones.
Here's what actually matters when you're evaluating SMS platforms:
Shopify integration depth. Your SMS tool should pull order data, product catalogs, and customer information without complicated setup. The best platforms integrate at checkout for seamless opt-in collection.
Pricing transparency. Some platforms advertise low starting prices but hit you with carrier fees, overage charges, or mandatory upgrades as you grow. Look for clear pricing that scales predictably.
Two-way conversational capabilities. One-way blasts are outdated. Modern SMS marketing means having actual conversations: answering questions, handling objections, and guiding customers to purchase.
Automation that actually saves time. Pre-built workflows for abandoned carts, welcome series, and shipping notifications should work out of the box, not require hours of configuration.
Compliance handled for you. TCPA violations can cost thousands per message. Your platform should manage opt-ins, quiet hours, and unsubscribe handling automatically.
Postscript alternatives at a glance
1. TxtCart
Best for: Shopify stores wanting AI-powered cart recovery
TxtCart positions itself as the first AI-native SMS platform for e-commerce, and that focus shows in its feature set.
While other platforms bolt AI onto existing infrastructure, TxtCart built its entire system around conversational AI from the ground up.
The platform's AI sales agent doesn't just send reminders. It engages customers in back-and-forth conversations, answers questions about products, handles objections, and guides shoppers toward completing their purchase.
According to TxtCart's data, this approach generates 45% reply rates and 30% conversion rates on abandoned cart messages.
Pricing:
What stands out:
- 14-day free trial includes $1,000 in credits
- 18x average ROI reported by customers
- 5-10 minute setup time
- Carrier fees passed through at cost ($0.0029/SMS)
The catch: TxtCart works best for stores with consistent traffic. If you're just starting out with low volume, you might not see the full benefit of their AI conversations.
2. Klaviyo
Best for: Stores wanting unified email and SMS marketing
Klaviyo has become the go-to platform for e-commerce brands that want everything in one place.
Instead of managing email in one tool and SMS in another, Klaviyo lets you orchestrate both channels from a single platform using shared customer data.
The real power comes from Klaviyo's segmentation capabilities. You can target customers based on purchase history, email engagement, browsing behavior, and predicted future actions.
The platform's RFM (Recency, Frequency, Monetary) segmentation automatically identifies your best customers, at-risk customers, and churned customers.
Pricing:
What stands out:
- Predictive analytics forecast customer behavior
- AI-powered subject line optimization
- 150+ pre-built integrations
- Unified customer profiles across email and SMS
The catch: Klaviyo's pricing scales quickly as your list grows. What starts affordable can become expensive once you cross 10,000 contacts. You also need to use both email and SMS to get full value; the SMS-only experience is limited.
3. Attentive
Best for: Enterprise and high-growth e-commerce brands
Attentive sits at the premium end of the SMS marketing spectrum.
The platform serves major brands with sophisticated needs: advanced AI, cross-channel orchestration, and enterprise-grade compliance and security.
The platform's patented two-tap mobile signup technology makes it easy to grow your subscriber list, while its AI suite optimizes send times, identifies subscribers, and personalizes content.
Attentive claims their AI Journeys feature drives 200% more revenue than standard automation.
Pricing: Custom pricing based on list size and message volume. Expect to pay more than competitors, with most estimates starting around $299/month for smaller lists.
What stands out:
- 150+ pre-built integrations
- Industry-leading deliverability rates
- Built-in TCPA compliance tools
- 24/5 dedicated support
- Cross-channel journeys (SMS, email, push)
The catch: Attentive requires a demo to get pricing, which makes it hard to compare costs upfront. The platform is also overkill for smaller stores; you're paying for capabilities you won't use if you're doing under $1M in annual revenue.
4. Omnisend
Best for: Budget-conscious stores needing omnichannel marketing
Omnisend takes a different approach than pure SMS platforms. It bundles email, SMS, and web push notifications into a single platform at a price point that undercuts most competitors.
The platform shines for stores that want to test multiple channels without committing to expensive tools for each.
All plans include the same features; you just pay more as your contact list grows. Even the free plan gives you access to automation workflows, segmentation, and all three channels.
Pricing:
Note: Pro plan includes bonus SMS credits equal to your monthly plan price.
What stands out:
- All features included on all plans
- 24/7 live chat and email support (even on free)
- 250+ email templates
- International SMS support for 209 regions
- Pre-built e-commerce workflows
The catch: Omnisend bills based on total contacts, including unsubscribed ones. You need to actively clean your list to avoid paying for dead weight. Some users also report that the email builder is stronger than the SMS features.
5. Yotpo
Best for: Stores wanting integrated reviews, loyalty, and SMS
Yotpo (formerly SMSBump) offers something most competitors can't match: a unified platform for reviews, loyalty programs, email, and SMS.
This integration creates powerful synergies. Your loyalty program can trigger SMS notifications for point balances and reward expirations.
Your review requests can go out via SMS for higher response rates.
The platform is built specifically for e-commerce, with deep Shopify integration that pulls in product catalogs, order data, and customer information. Yotpo boasts 180+ data points for segmentation and 39+ automation triggers.
Pricing: Pay-as-you-go SMS pricing starting at approximately $0.0072 per message. Email plans start at $160/month.
What stands out:
- Reviews, loyalty, email, and SMS in one platform
- 180+ integrations
- RFM and Retention Dashboards
- Case studies show 8x ROI from loyalty programs
- AI-powered review summaries
The catch: Yotpo's pricing can become complex when you're using multiple products. The platform also has a steeper learning curve than simpler alternatives; you're trading ease of use for power.
6. SimpleTexting
Best for: Stores wanting simple, reliable SMS without complexity
Sometimes you don't need AI, predictive analytics, or cross-channel orchestration.
You just need to send texts reliably and affordably. That's where SimpleTexting comes in.
The platform strips away complexity to focus on core SMS marketing: mass texting, two-way messaging, auto-replies, and drip campaigns.
You get unlimited contacts and unlimited keywords, so you never have to worry about hitting limits as you grow.
Pricing:
What stands out:
- Unlimited contacts on all plans
- Unlimited text-to-join keywords
- Rollover credits (unused credits roll to next month)
- 30-day money-back guarantee
- Live support 7 days per week
The catch: SimpleTexting doesn't have the e-commerce-specific features of competitors like abandoned cart workflows or Shopify product catalog integration. You'll need to build more yourself or use Zapier connections.
7. Emotive
Best for: Brands wanting human-like conversational SMS at scale
Emotive occupies a unique position in the SMS marketing space.
The platform combines AI automation with live agents (called TextPros) to create conversations that feel genuinely human. When the AI encounters a situation it can't handle, a live agent steps in seamlessly.
This hybrid approach works well for brands that want the scale of automation without sacrificing the personal touch.
Emotive also offers a 5x ROI guarantee, which shows confidence in their platform's ability to drive revenue.
Pricing:
Note: Pro and Advanced plans have minimum spend requirements ($200 and $400 respectively).
What stands out:
- AI + live agent hybrid for human-like conversations
- 5x ROI guarantee
- Dedicated copywriters on higher tiers
- Strong attribution tracking
The catch: Emotive is expensive compared to pure software solutions. You're paying for the human agent component, which may not be necessary for every brand.
How to choose the right Postscript alternative for your store
With seven solid options, how do you pick? Here's a simple framework based on where you are in your growth journey:
Just starting out (under $500K annual revenue): Start with Omnisend or SimpleTexting. Both offer affordable entry points and room to grow. Omnisend gives you more features; SimpleTexting gives you more simplicity.
Growing fast ($500K-$5M) with strong Shopify integration: TxtCart or Yotpo. TxtCart wins if AI-powered cart recovery is your priority. Yotpo makes sense if you also need reviews and loyalty.
Need unified email and SMS: Klaviyo is the clear choice. The predictive analytics and unified customer profiles justify the cost once you have enough data.
Enterprise scale ($5M+) with complex needs: Attentive or Emotive. Attentive offers more integrations and AI tools. Emotive provides the human touch that premium brands often want.
Switching from Postscript: what to expect
Migrating SMS platforms isn't as painful as switching email providers, but there are still considerations:
Subscriber lists: You can export your subscriber list from Postscript and import it to most alternatives. Just ensure your new platform verifies compliance (TCPA requires documented consent).
Templates and workflows: You'll need to rebuild automations in your new platform.
Most take 1-2 weeks to fully configure. Build these in parallel with your Postscript account running to avoid gaps.
Deliverability: Your sending number will change, which means subscribers won't recognize the new number immediately. Send a "new number" announcement campaign to reduce confusion.
Timing: Plan your migration during a slower sales period. Black Friday week is not the time to switch SMS platforms.
Beyond SMS: handling the support volume that comes with growth
As your SMS marketing drives more sales, you'll face a related challenge: more customer support inquiries. More orders mean more "where's my order" questions, more return requests, and more product questions.
This is where Ringly.io becomes relevant. While SMS platforms handle marketing, Ringly handles inbound phone support with an AI agent named Seth.
Seth answers calls 24/7, looks up orders, processes returns, and escalates complex issues to your team.
The platform integrates with Shopify and resolves approximately 70-73% of calls without human intervention.
For stores scaling their SMS marketing and seeing support volume spike, it's worth considering as a complementary tool.
