"AI SMS" is one of the most abused phrases in the Shopify app store right now. Half the apps wearing the badge are just sending preset 3-message cart flows with a name merge tag. That's not AI. That's a mail merge with a fancy label.
The handful of apps actually doing something useful with AI fall into four buckets: AI copywriting, AI segmentation, AI send-time optimization, and AI conversational two-way replies. Most apps do one or two of those well. A few do all four. And one app on this list does something nobody else does: it ties SMS to the inbound phone call, so the customer's text and the customer's call live in the same conversation.
This post is built for Shopify operators picking an SMS app in 2026. Yotpo shut down its SMS product in December 2025 (per Yotpo's exit announcement), the FCC tightened AI disclosure rules on text messages, and the pricing gap between entry apps ($29/mo) and enterprise ones ($5K+/mo) keeps widening. You need to pick well.

How we evaluated these AI SMS apps
We tested each app on the criteria that actually matter for a Shopify store running SMS in 2026:
- Actual AI capability: Does the AI do something measurable (conversational replies, segment generation, send-time prediction), or is it a buzzword on the pricing page?
- Shopify integration depth: Native Shopify data sync, or a Zapier bridge with a 5-minute lag?
- Pricing transparency: Is the monthly cost predictable, or does it spiral once your list grows?
- TCPA support: Double opt-in, STOP-word handling, AI disclosure baked in, or left to you?
- Two-way SMS: Can the app respond to a customer reply with context, or is it send-only?
- Cart-recovery performance: Real recovery rates we can verify, not vendor-claimed numbers without methodology.
- Migration support: Yotpo is gone, Bird is wobbly. Can the app onboard a 50K-contact list without a meltdown?
That gave us a ranked list of 10 apps. Ringly comes in first because it's the only one solving the SMS-plus-phone-call problem most Shopify stores don't even know they have.
What "AI" actually means in a Shopify SMS app
When a vendor says "AI SMS," it usually means one of four things. Here's how to tell which one you're getting:
| AI feature | What it actually does | Apps that do it well |
|---|---|---|
| AI copywriting | Generates subject lines, message variants, opener hooks | Klaviyo, Attentive, TxtCart |
| AI segmentation | Builds audience segments from natural-language prompts or behavior data | Klaviyo, Omnisend, Maestra |
| AI send-time | Predicts the best send time per subscriber | Klaviyo, Attentive |
| AI conversational two-way | Real replies to customer texts using context, not preset answers | Ringly, TxtCart, Postscript, Emotive |
Most apps do one or two. Almost none do all four. And the FCC's 2024 AI disclosure rule (per ActiveProspect's TCPA guide) means any AI-generated SMS now has to disclose AI use at the start of the message. Only a few apps bake that into the template flow. The rest leave the legal exposure to you.
Quick comparison: AI SMS apps for Shopify
| App | Best for | Starting price | AI capability | Free trial |
|---|---|---|---|---|
| Ringly.io | Phone + SMS combo | $349/mo | Conversational AI on call + SMS | 14 days (Pro) |
| Klaviyo | Email + SMS unified | ~$15/mo (SMS credits) | Copy, segment, send-time | Yes |
| Postscript | SMS-first DTC | $0 + $49 min | Two-way AI replies | $100 credit |
| Attentive | $5M+ enterprise | $2-3K/quarter | Full AI suite | Demo only |
| TxtCart | Cart recovery | $29/mo | Conversational AI | 14 days |
| Recart | Flow-heavy stores | $299/mo | A/B + flow library | Demo |
| Omnisend | Budget SMB | Free + SMS rates | Segment AI | Yes |
| Emotive | AI + human hybrid | $100/mo | CartAI + agents | Demo |
| SuperSMS.AI | Pay-as-you-go AI | Free install | Campaign AI | Yes |
| Maestra | Omnichannel enterprise | $4,979/mo | CDP + AI personalization | Demo |
If you want to skip the deep dive: most Shopify stores under $1M will land on Klaviyo (if they already have email there), TxtCart (if cart recovery is the main goal), or Ringly (if their customers actually call).
The 10 best AI SMS apps for Shopify
1. Ringly.io
Best for: Shopify stores where customers actually call and want a text back
Ringly.io is an AI phone agent for Shopify stores, not a bulk-SMS marketing platform. Its AI agent, Seth, answers inbound calls 24/7 and resolves about 73% of them without human handoff. The part most people miss: Seth also sends SMS during and after calls. Callback confirmations, checkout links, order status updates, return labels. The customer's text and the customer's call live in the same conversation, because they're the same customer on the same phone.
That's the gap nobody else is filling. Klaviyo doesn't know about the call. Postscript doesn't know about the call. Ringly sees both.
Pricing
| Plan | Price | Minutes | Overage |
|---|---|---|---|
| Grow | $349/mo | 1,000 (~500 calls) | $0.29/min |
| Pro | $799/mo | 2,500 (~1,250 calls) | $0.19/min |
| Enterprise | Custom | 5,000+ | Contact sales |
14-day free trial on Pro. There's a 65% resolution guarantee. If Seth resolves under 65% of calls in 90 days, you get the last 3 months refunded.
What works
- Native Shopify lookup: Seth pulls real-time order data via the check order status feature, processes returns, checks inventory without custom dev. Same integration runs on calls and on the SMS handoff.
- SMS triggered by call context: when Seth finishes a call about an order, the customer gets a tracking text. When a caller asks for a callback, the agent texts a confirmation. The SMS uses the call as the trigger, not a marketing list. The abandoned cart recovery flow uses the same pattern.
- 65% resolution guarantee: rare in this category. If we miss it, we refund the last three months.
- 40-language support: same agent, no add-on. Useful for stores serving non-English speakers.
- 3-minute setup: connect Shopify, point your number at us, done. No code, no engineer.
What doesn't
- Not a bulk-SMS blast platform: if you want to send a Black Friday blast to 50K subscribers, use Klaviyo or Postscript. Ringly's SMS is conversational and call-anchored, not broadcast.
- Monthly minimum: $349/mo entry doesn't make sense for stores doing under $200K/yr in revenue. The math only works once you have real call volume.
- SMS volume tied to call volume: you can't 10x SMS sends overnight. The SMS happens because someone called. That's the whole point.
Why it ranks #1: this is the only app in the list where SMS is anchored to a real two-way conversation (the call), not a marketing list. For Shopify stores doing $200K+/mo where customers actually pick up the phone, no other app touches it. The deeper context lives in our AI phone agents for Shopify primer.
If you're on Shopify and your customers call, Ringly.io gets Seth answering in about three minutes. Try it free for 14 days.
2. Klaviyo
Best for: Stores already on Klaviyo email who want SMS in the same UI
Klaviyo is the marketing automation standard for Shopify. 117K+ brands run on it. If you're already using Klaviyo for email, adding SMS in the same platform is a no-brainer move. The flows, segments, and data all carry over. The AI layer (K:AI Customer Agent, AI subject lines, predictive analytics) is genuinely good, just not as deep on the SMS side as on email.
Pricing
SMS pricing is credit-based and varies by country. Entry starts around $15-$20/mo for the first 150 SMS credits and scales with your contact list. A 50K-contact list can run $500-$1,500/mo. There's a free trial.
What works
- Deepest Shopify data sync: Klaviyo pulls 200+ Shopify data points in real time. Browse behavior, cart activity, purchase history, lifetime value. Other apps don't get close.
- Unified email + SMS + push flows: one customer, one flow, one source of truth. Coordinating channels is genuinely easy here.
- K:AI Customer Agent: a 24/7 personal-shopping assistant that handles FAQ-style replies and recommendations.
- AI subject lines and SMS copy: trained on Klaviyo's massive corpus of past sends. The suggestions are usable, not just demo-grade.
- Predictive analytics: lifetime value, churn risk, replenishment dates. Useful for SMS targeting.
What doesn't
- Pricing balloons past 50K contacts: a common complaint in the Shopify operator community. Once you're sending real volume, the bill gets ugly.
- SMS UI feels secondary to email: this is an email tool with SMS bolted on. It works, but the workflow shows its roots.
- Compliance is "hands-off": Klaviyo gives you the tools but doesn't enforce TCPA double opt-in or AI disclosure. That's on you.
Why it ranks #2: best general-purpose AI SMS if you're already running Klaviyo email. If you're not, the case is weaker. The Klaviyo alternatives post covers options if pricing is an issue.
3. Postscript
Best for: Mature DTC brands doing SMS as a primary channel
Postscript is the Shopify-native SMS specialist. Pure SMS, no email, no push. Built from the ground up around the channel, including TCPA double opt-in and Brand Center compliance tooling. About 2,423 Shopify stores currently use it (per BootLeads), and it carries a 4.9/5 rating on the Shopify App Store. The two-way Postscript AI replies are real, not preset templates.
Pricing
| Plan | Cost | SMS rate |
|---|---|---|
| Starter | $0 + $49/mo minimum | $0.015 |
| Growth | $100/mo | $0.01 |
| Professional | $500/mo | $0.007 |
| Enterprise | Custom | Custom |
$100 credit for the first 30 days. Dedicated short codes are $750/mo extra.
What works
- TCPA double opt-in baked in: the most lawsuit-proof setup of any app on this list. Auto-enforces opt-in flow, STOP handling, and compliance language.
- Two-way AI replies (Postscript AI): real conversational responses with brand-voice training via Brand Center.
- Mature Shopify-native feature set: campaigns, automations, segments, keyword opt-ins, branded short links. All built for the Shopify operator.
- 4.9/5 on Shopify App Store: rare at this scale.
What doesn't
- "Free" $0 plan has $49 monthly minimum: a recurring frustration in operator threads. Don't sign up expecting $0.
- Expensive past 5K subscribers: once you scale, the per-message rate plus platform fee adds up fast.
- Forced tier migrations: some long-time customers have been moved to pricier tiers with new monthly charges layered on top.
Why it ranks #3: still the SMS operator standard for DTC brands doing $1M+ where SMS is the primary marketing channel.
4. Attentive
Best for: $5M+ ARR brands with budget for managed service
Attentive is the enterprise pick. Managed onboarding, agency-driven implementations, full AI suite. The platform is mature, the personalization is real, and the attribution tooling is some of the strongest in the category. The catch is the contract. Reports from operators (per Asktimmy's pricing breakdown) put quarterly minimums at $2-3K, with 6-12 month commitments and exclusivity clauses that block running Klaviyo or Postscript in parallel.
Pricing
Custom and not published. Reported $2-3K quarterly minimum spend. Per-message rates plus subscriber count plus AI add-on fees (AI Pro, AI Grow, AI Journeys each carry separate fees).
What works
- Full AI suite: message generation, send-time optimization, audience segmentation, triggered messaging. All four AI buckets covered.
- Managed onboarding: white-glove implementation with dedicated success managers.
- Strong attribution tooling: the multi-touch attribution is one of the best in the category.
- Deep agency network: if you work with a CRO/email agency, they probably know Attentive.
What doesn't
- Pricing opacity: no published rates, every contract negotiated.
- Contract lock-in: 6-12 month commitments with quarterly minimums you owe even if you don't send.
- Exclusivity clauses: some contracts block you from running Klaviyo or Postscript at the same time, which kills flexibility.
- Data portability friction: operators have flagged difficulty exporting subscriber lists when leaving.
Why it ranks #4: the right call at $5M+ if you want a managed service. Below that, the math doesn't work. See Attentive alternatives if the contract terms feel heavy.
5. TxtCart
Best for: Sub-$1M Shopify stores focused on cart recovery
TxtCart is the AI-conversational cart-recovery specialist. The pitch: real two-way AI replies that recover 33% of abandoned carts (vendor data). The $29 entry plan and 10x ROI guarantee on the Managed tier make it the easiest "try it for a month" option for smaller stores. The AI agent actually responds to objections, offers dynamic discounts, and closes carts via text without the customer touching a checkout page.
Pricing
| Plan | Cost | SMS rate |
|---|---|---|
| Starter | $29/mo minimum | $0.009 SMS |
| Growth | $79/mo | $0.008 |
| Pro | $399/mo | $0.007 |
| Managed | $999/mo | $0.006 |
14-day free trial with credits included. 10x ROI guarantee on the Managed plan.
What works
- Real two-way AI conversational replies: not preset answers. The agent handles objections like shipping cost, sizing, delivery time.
- $29 entry, no enterprise minimums: the easiest entry point in this list for stores under $50K/mo revenue.
- 4.9/5 on Shopify App Store across 377 reviews: well-tested with operator feedback.
- 10x ROI guarantee on Managed plan: rare in the category and tied to actual performance.
What doesn't
- Thinner feature set than Klaviyo: no email, no push, no predictive analytics. SMS only.
- Support response varies: some operator reviews mention slow response on lower tiers.
- Less mature compliance than Postscript: TCPA tooling is there but not as enforced.
Why it ranks #5: the best entry-point for AI conversational cart recovery on Shopify if you're below $1M and SMS is your primary channel.
6. Recart
Best for: Stores doing high-volume automated flows
Recart started in Facebook Messenger and pivoted hard to SMS. The platform is built around flows: welcome series, cart recovery, browse abandonment, post-purchase. Automation library is broad. The "AI" framing is mostly A/B testing and predictive scoring, not conversational replies. If you have a flow-heavy strategy and want done-for-you setup, Recart fits.
Pricing
| Plan | Cost | SMS included | SMS rate |
|---|---|---|---|
| Starter | $299/mo (12-mo commit) | 23K SMS | $0.01 |
| Pro | $499/mo | 41,583 SMS | $0.0085 |
| Scale | $999/mo | 100K SMS | $0.007 |
| Enterprise | Custom | Custom | from $0.0045 |
What works
- Strong automation library: pre-built flows for welcome, cart, browse, post-purchase, win-back.
- Aggressive volume pricing past Scale tier: per-message rates beat most competitors at 100K+ sends.
- White-glove option at Scale+: managed campaign creation and dedicated success.
What doesn't
- 12-month commitment: no monthly cancellation on lower tiers.
- No explicit AI conversational features: A/B testing is not AI in the modern sense.
- Messenger focus less relevant in 2026: that part of the product has aged badly.
- Less Shopify-native than Klaviyo or Postscript: integration depth lags.
Why it ranks #6: still solid for flow-heavy operators who want managed campaigns and don't mind a 12-month commit.
7. Omnisend
Best for: SMB Shopify stores on tight budgets or Yotpo refugees
Omnisend is the budget all-in-one. Email + SMS + push in one platform with a real free tier and the cheapest SMS rates in this list at scale. It's also one of two official Yotpo-migration partners, which makes it the easy default for merchants moving off Yotpo's shuttered SMS product (per Recapture's migration guide). The AI is shallow compared to Klaviyo, but the AI segment builder (natural-language prompts) is surprisingly useful.
Pricing
| Plan | Cost | Includes |
|---|---|---|
| Free | $0 | 500 emails, 250 contacts |
| Standard | $11.20/mo | 6K emails, 500 contacts |
| Pro | $41.30/mo | Unlimited emails, 2.5K contacts, SMS from $0.007 |
| Custom | Contact sales | 150K+ contacts |
US SMS rates: $0.007-$0.009 by monthly volume.
What works
- Genuine free tier: 250 contacts, 500 emails. Real, not a trial.
- Cheapest SMS rates at scale: $0.007/SMS at $1K+ monthly volume.
- Email + SMS + push in one UI: the right model for SMBs.
- AI segment builder: natural-language prompts work well for basic segmentation.
What doesn't
- SMS feels secondary to email: similar critique to Klaviyo, but more pronounced.
- AI features are shallow: nothing close to K:AI or Attentive's AI Journeys.
- Less Shopify-native than competitors: integration is fine but not deep.
- Reporting can lag: some operators report 2-4 hour delays on cart-recovery attribution.
Why it ranks #7: best value for SMBs and Yotpo refugees, particularly under 5K contacts.
8. Emotive
Best for: Stores wanting AI plus human agent backstop
Emotive blends AI cart-recovery (their CartAI tool) with real human agents who jump into the conversation when the AI hits its limit. The hybrid model is genuinely useful for stores where conversion sensitivity is high (luxury goods, high-AOV items). Reported numbers: 17% cart-recovery conversion vs. 6% for one-way bulk SMS, per Emotive's data.
Pricing
| Plan | Cost | List size | SMS rate |
|---|---|---|---|
| Starter | $100/mo | <2K | $0.015 SMS |
| Pro | $200/mo | 2K-5K | $0.01 |
| Advanced | $300/mo | 5K-10K | $0.008 |
| Enterprise | Custom | 10K+ | Custom |
5X ROI guarantee for qualified sites with 10K+ monthly visits.
What works
- Real cart-recovery conversion: 17% on cart-recovery texts beats the 6% one-way industry average.
- Human + AI handoff: when the AI doesn't know an answer, a human steps in. Useful for high-AOV stores.
- White-glove onboarding: included in all tiers.
- Price-match guarantee: Emotive will match or beat any competitor's contract.
What doesn't
- Smaller ecosystem than Klaviyo or Postscript: fewer integrations, fewer agency partners.
- Opaque enterprise pricing: contact-sales-only past 10K subscribers.
- Hybrid replies can be slower than pure AI: human-in-the-loop introduces delay.
Why it ranks #8: nice middle ground for stores where AI alone isn't enough but a full agency-managed service is overkill.
9. SuperSMS.AI
Best for: Stores experimenting with AI MMS campaigns at low commitment
SuperSMS.AI is a newer AI-first SMS entrant. Free to install, true pay-as-you-go pricing, AI campaign generation across SMS and MMS. The product is younger and the install base smaller (69 reviews on the Shopify App Store, 4.1/5 rating with a notable 13% one-star share flagging support and reliability issues). Worth a look for experimentation. Not for mission-critical stacks yet.
Pricing
- Free to install
- $0.035/SMS US/CA, $0.079/MMS
- Per-country international rates
What works
- Pay-as-you-go with no minimum: true zero commitment.
- AI personalization across SMS and MMS: rare to see real MMS AI at this price.
- Free to install: low-risk testbed.
- Behavioral and location-based segmentation: AI-driven.
What doesn't
- Higher per-message rate than Klaviyo or TxtCart: $0.035 is ~3x Postscript's $0.015 Starter rate.
- 13% one-star reviews flagging support reliability: notable for an app with only 69 total reviews.
- Smaller install base: less battle-tested.
- Newer team: less operator feedback to draw on.
Why it ranks #9: worth a test on a side store. Not where I'd put a $50K/mo SMS budget yet.
10. Maestra
Best for: Stores running multi-region SMS with email parity and a real CDP
Maestra is an omnichannel CDP plus marketing automation. Email, SMS, MMS, RCS, push, on-site personalization, all in one platform. European-flavored, enterprise-priced. The lowest per-SMS rate in this list ($0.0045 + carrier fees), but the entry plan is $4,979/mo. That gates this to enterprise stores doing real omnichannel.
Pricing
All-in monthly pricing starts at $4,979/mo, tiered by active customer profile count (10K / 1M / 3M / 65M). Free integration and migration. SMS at $0.0045 + carrier fees, RCS at $0.0058-$0.0137.
What works
- Lowest per-SMS rate in this list: $0.0045 makes Maestra cheap on a per-send basis at volume.
- Full omnichannel including RCS: rare to see RCS pricing published.
- Free white-glove migration: real onboarding included.
- 20x ROI cited by clients: per Maestra's site.
What doesn't
- $4,979/mo entry is enterprise-only: not for stores under $5M ARR.
- Less Shopify-native than Klaviyo: integration works but isn't built around Shopify-first like Postscript.
- Smaller US footprint: most marketing material is European.
- Opaque tier structure: pricing breakpoints between 10K/1M/3M profiles aren't clear.
Why it ranks #10: niche choice for global enterprise merchants running real omnichannel.
SMS plus phone calls: the channel most Shopify stores split in half
Here's something most operators miss. A customer's phone is one device, not two channels. They use it to call you. They use it to text. They use it to read your texts. From the customer's point of view, it's one phone, one conversation, one expectation that you remember the context.
But most Shopify stores run SMS and phone calls as completely separate systems. The SMS app doesn't know about the call. The call-center tool doesn't know about the text. So you get this awkward dance where a customer calls, asks about an order, hangs up, then gets a generic SMS campaign three days later about a sale on something unrelated.
This is where the AI-phone-plus-SMS combo matters. When Ringly's Seth handles an inbound call, the agent can text the caller a checkout link, callback confirmation, or order tracking link mid-call. The SMS happens because of the call, not in spite of it. That's a different channel architecture than what Klaviyo or Postscript do, and it solves a different problem: not "how do I market to my list," but "how do I close the loop on the conversation I'm already having."
For Shopify stores where customers actually pick up the phone (and most stores doing $200K+/mo have this volume, even if they don't realize), the SMS that matters most isn't the broadcast. It's the one tied to a real call. Pair that with the right marketing-SMS tool for blasts and you've got the whole channel covered. See our breakdown of WISMO calls for one specific example of how this plays out in practice.
Start your free trial of Ringly. Setup takes three minutes.
TCPA and AI disclosure: the rule most Shopify SMS apps don't surface
The FCC tightened the rules on AI-generated SMS in 2024. The practical effect for Shopify operators: any text generated by AI now needs explicit consent (the subscriber agreed to receive AI messages) and AI disclosure at the start of the message itself. Klein Moynihan Turco, a TCPA-focused law firm, has been tracking the resulting lawsuit surge against companies using AI-generated SMS without proper disclosure. The TCPA penalties stack at $500 per text minimum, $1,500 per text for willful violations.
For your store, here's the practical 3-step compliance check:
- Opt-in flow mentions AI: your subscriber consent language must specifically say messages may be AI-generated. Generic "we may text you offers" doesn't cut it anymore.
- AI disclosure in message body: AI-generated texts must disclose AI use at the start. A common pattern: "AI-generated reply from [Brand]: ..."
- STOP handling and opt-out logging: every message needs a STOP path, and the opt-out has to be logged immediately and respected across every system you run.
Of the apps on this list, Postscript bakes the most TCPA tooling in by default (double opt-in, automatic STOP handling, Brand Center compliance review). Klaviyo and Attentive give you the tools but leave enforcement to you. The newer entrants (SuperSMS.AI, TxtCart) are still catching up on the AI-disclosure layer. Whichever app you pick, the consent and disclosure piece is on you to verify.
How to choose the right AI SMS app for your Shopify store
The right pick depends on what problem you're actually solving. Use this:
- Choose Ringly if customers call your store and you want SMS to follow the call (callback confirmations, order status, checkout links from the call agent). Pair it with one of the marketing-SMS apps below.
- Choose Klaviyo if you already run Klaviyo email. Adding SMS in the same UI is the path of least resistance and the AI works well across both channels.
- Choose Postscript if SMS is your primary marketing channel, you're doing $1M+ in revenue, and you need TCPA compliance baked in by default.
- Choose Attentive if you're at $5M+ ARR and want a managed service. The contract terms are heavy but the platform is enterprise-grade.
- Choose TxtCart if you're under $1M and your main SMS goal is cart recovery via real conversational AI. The $29 entry is hard to beat.
- Choose Recart if your strategy is flow-heavy and you want a deep automation library with an option for managed campaigns.
- Choose Omnisend if budget is the priority and you need email + SMS + push in one tool, or you're migrating off Yotpo.
- Choose Emotive if you sell high-AOV products and want AI plus a human agent backstop for cart-recovery conversations.
- Choose SuperSMS.AI if you want to test AI MMS at zero commitment on a side store.
- Choose Maestra if you're an enterprise running omnichannel across multiple regions with RCS in the mix.
For most Shopify operators reading this, the realistic stack is two apps: one for inbound phone + transactional SMS (Ringly), one for outbound marketing SMS (Klaviyo or Postscript). The two layers don't overlap. They cover different jobs. If you want more context on the broader stack, our roundup of Shopify marketing apps covers the surrounding tools, and the best AI tools for Shopify post lays out adjacent categories.
Frequently asked questions
What's the difference between AI SMS and regular SMS marketing on Shopify?
Regular SMS marketing sends preset messages on a schedule. AI SMS does one or more of the following: generates personalized copy per subscriber, builds segments from behavior data, optimizes send time per recipient, or responds to two-way customer replies with context. Most apps marketed as "AI SMS" only do one or two of these, so check the feature list before you sign up.
How much does AI SMS cost for a Shopify store?
Entry pricing starts around $11-$29/month (Omnisend, TxtCart). Mid-tier SMS-first platforms (Postscript, Recart) run $100-$500/month plus per-message rates. Enterprise tools (Attentive, Maestra) start at $2-5K/month with contract minimums. Per-message rates run $0.0045 to $0.035 depending on platform and volume.
Is AI-generated SMS legal under TCPA?
Yes, if you have explicit opt-in consent that mentions AI-generated messages and you disclose AI use at the start of each AI-generated text. The FCC tightened this rule in 2024, and TCPA lawsuits against companies using AI without disclosure have spiked. Penalties run $500-$1,500 per text in violation.
What's the best free AI SMS app for Shopify?
Omnisend has the most generous true free tier (250 contacts, free email, pay-per-send SMS). SuperSMS.AI is free to install with pay-as-you-go SMS pricing. TxtCart's $29 starter is the cheapest real entry tier if you want conversational AI cart recovery without true free.
Can AI SMS handle two-way conversations or just send-and-forget?
A few apps do real two-way conversational AI: Ringly (on the phone + SMS combo), TxtCart, Postscript (with Postscript AI), and Emotive (with human handoff). Most other "AI SMS" apps are one-way: AI generates the copy and AI builds the segment, but if a customer replies, you handle it manually or the message goes nowhere.
How does Yotpo's shutdown affect my SMS strategy?
Yotpo retired its SMS product on December 31, 2025. If you were on Yotpo, you've already had to migrate. Yotpo's official replacement partners are Attentive and Omnisend (both offered free migration and Yotpo-equivalent pricing for one year). Klaviyo, Postscript, and TxtCart are also active in picking up Yotpo refugees with custom migration support. For the broader picture on Shopify customer-touch automation post-Yotpo, our Shopify AI voice support and WISMO automation breakdowns cover what to do on the phone side.
The take
The Shopify SMS apps that win in 2026 are the ones where AI does something measurable: real conversational replies, accurate copy, fraud-safe segmentation, TCPA-compliant disclosure. The ones losing are the ones where "AI" is a badge on a pricing page and the underlying product is the same preset cart-recovery flow we've been running since 2019.
The other shift: phone calls and SMS belong to the same channel from your customer's perspective. Most Shopify operators have spent a decade running them as separate stacks. The opening in 2026 is to fix that. If your customers call, Ringly is the right anchor for the phone side, with Klaviyo or Postscript handling the broadcast SMS side. Two apps, one phone, one conversation.
