5 Best SMS Marketing Apps for Shopify

SMS marketing gives Shopify merchants a direct way to reach customers, recover abandoned carts, promote new products and turn existing customers into repeat buyers.

But choosing the right SMS marketing app isn't just about sending texts.

The best platform for your store will depend on where your customers are, how sophisticated your marketing stack is, how much visibility you need into revenue and ROI, and whether you want SMS as part of a broader omnichannel platform or as a dedicated revenue channel.

For Australian Shopify merchants, there are additional considerations too, from local SMS pricing and support to Australian messaging requirements and infrastructure.

We've compared five of the best SMS marketing apps for Shopify in 2026 to help you find the right fit.

The 5 best SMS Marketing Apps for Shopify

1. Kudosity: Best for Australian Shopify merchants

Best for: Australian Shopify merchants and growing ecommerce brands looking to automate customer engagement, recover abandoned carts and drive measurable revenue with scalable messaging.

Kudosity is an Australian-owned business messaging platform that helps Shopify merchants turn customer interactions into measurable revenue. With SMS, MMS, WhatsApp and RCS capabilities, including SMS fallback for supported messaging workflows, Kudosity enables businesses to engage customers across multiple messaging channels.

Its direct Shopify integration connects customer, order and product data with SMS marketing, enabling merchants to create personalised campaigns, segment audiences and automate customer journeys without relying on third-party middleware.

From recovering abandoned carts to encouraging repeat purchases, Kudosity combines ecommerce automation with real-time reporting, revenue attribution and flexible pricing that scales with your business.

Shopify integration and automated customer journeys

Kudosity offers five ready-to-use Shopify SMS automation flows, helping merchants engage customers throughout the buying journey:

• Abandoned cart recovery: Automatically send personalised reminders with checkout links to bring shoppers back and recover lost sales.

• Order notifications: Keep customers informed with automated order confirmations and shipping updates.

• Post-purchase engagement: Welcome new customers with personalised discount codes and follow-up reminders.

• Repeat purchases and replenishment: Trigger product- or collection-based reminders to encourage customers to buy again.

• Birthday campaigns: Reward customers with personalised birthday offers, greetings and follow-up messages.

Merchants can customise message templates, timing and offers, while built-in controls support consent management, opt-outs and appropriate sending hours.

Real-time reporting and SMS revenue attribution

Beyond delivery rates and clicks, Kudosity helps Shopify merchants understand the revenue their messaging generates.

By connecting Shopify purchase data with SMS activity, merchants can track campaign performance, recovered carts, attributed revenue and messaging costs.

Kudosity uses campaign-specific attribution rules, including SMS link clicks, checkout activity and discount code redemption, to connect purchases back to messaging campaigns.

This gives businesses clearer visibility into which messages, offers and customer segments are driving revenue, helping them optimise their SMS marketing investment.

That gives merchants a straightforward way to answer:

How much did I spend on this SMS campaign, and how much revenue did it generate?

Campaign-level ROI makes it easier to identify which messages, offers and audiences are generating revenue and where SMS investment is delivering the strongest returns.

Platforms such as Klaviyo also provide SMS revenue attribution and offer sophisticated cross-channel analytics. Kudosity takes a more focused approach: giving merchants clear visibility into SMS campaign costs and the Shopify revenue attributed to their messaging.

For merchants who need complex attribution across email, SMS and other marketing channels, a broader marketing platform may be more suitable. For merchants who want to understand SMS spend versus SMS-attributed Shopify revenue, Kudosity keeps the measurement focused and easy to understand.

Built for Australian messaging, backed by local expertise

With more than 20 years of Australian messaging experience, Kudosity combines direct connectivity with major Australian carriers, reliable messaging infrastructure and local expertise.

Businesses benefit from Australian-based support, a 24/7 helpdesk and dedicated account management for eligible customers, including guidance on messaging compliance and Sender ID requirements.

For growing businesses and enterprise customers, Kudosity also offers API integrations, MCP server capabilities for AI assistants, and security credentials including ISO 27001 and SOC 2 Type II certifications.

Transparent pricing

Kudosity's Shopify app is free to install, with flexible pay-as-you-go SMS pricing and volume-based discounts.

For Australian customers, Kudosity publishes its SMS pricing in Australian dollars, making it easier for local merchants to forecast messaging costs without converting US pricing or accounting for separate platform and carrier charges.

Flexible pricing that scales with your SMS volume

Kudosity makes it easy to start with SMS and scale your spend as your messaging grows. Shopify merchants can top up their account with exactly what they need, with custom amounts from $50 to $2,000 in whole-dollar increments, or choose quick top-up packs of $100, $250, $500, $1,000 or $2,000.

Rather than locking every merchant into the same pricing structure, Kudosity can also offer volume-based discounts for businesses with larger or growing SMS requirements.

This gives merchants the flexibility to start at a comfortable spend, increase their messaging as they see results, and access more competitive rates as their SMS volume grows.

Kudosity pros

• SMS, MMS, WhatsApp and RCS messaging capabilities, with SMS fallback for supported workflows

• Direct Shopify integration with customer, order and product data synchronisation

• Five ready-to-use SMS automation flows for cart recovery, order updates, post-purchase engagement, repeat purchases and birthdays

• Customer segmentation and personalised SMS campaigns

• Shopify revenue attribution, cart recovery reporting and campaign-level ROI visibility

• Transparent AUD pricing, flexible PAYG and SMS volume discounts

• Direct Australian carrier connectivity, local support and 24/7 helpdesk

• Dedicated account management for eligible customers

• Enterprise-grade security and messaging APIs

  MCP server capabilities for connecting AI assistants such as ChatGPT and Claude to messaging APIs

Kudosity cons

• Primarily focused on messaging rather than offering an all-in-one email marketing and customer data platform

• Cross-channel attribution is more limited than platforms offering unified email, SMS and marketing analytics

• Smaller Shopify App Store review footprint than some established competitors

Choose Kudosity if: You're an Australian Shopify merchant or growing ecommerce brand looking to automate SMS marketing, increase repeat purchases and track messaging ROI, with reliable infrastructure, transparent pricing and local support.

2. Attentive: Best for enterprise ecommerce

Best for: Larger ecommerce brands that need advanced personalisation, automation and enterprise-scale marketing capabilities.

Attentive is designed for sophisticated ecommerce marketing programs and larger organisations.

Its platform combines SMS with email and offers advanced segmentation, automated customer journeys, personalisation, list growth and AI-powered marketing capabilities.

For large marketing teams, that sophistication can be a significant advantage.

For smaller Shopify merchants, however, Attentive may offer considerably more capability than they actually need.

Pricing

Attentive doesn't provide the same level of simple public per-message pricing as some alternatives.

Pricing can depend on factors such as message volume, subscriber count, channels and premium products, meaning merchants generally need to speak with Attentive to understand their likely total cost.

Attentive pros

• Strong enterprise capabilities

• Advanced personalisation and segmentation

• SMS and email capabilities

• Sophisticated automation

• Designed for high-volume ecommerce programs

• AI and conversational marketing functionality

Attentive cons

• Pricing is less transparent than some alternatives

• More suited to larger organisations and marketing teams

• Potentially greater implementation and management overhead

• May be excessive for merchants that primarily need straightforward SMS marketing

Choose Attentive if: You're a larger ecommerce business looking for an enterprise-grade marketing platform and advanced personalisation is more important than simplicity.

3. Klaviyo: Best for combined email and SMS marketing

Best for: Shopify merchants that want email, SMS and customer data managed through a single marketing platform.

Klaviyo is one of the biggest names in ecommerce marketing and an obvious choice for Shopify merchants already using it for email.

Rather than treating SMS as a standalone channel, Klaviyo allows businesses to coordinate SMS with email and other customer communications using shared customer profiles, segmentation and automated flows.

That makes Klaviyo particularly powerful for merchants running sophisticated lifecycle marketing programs.

Sophisticated SMS analytics and attribution

Klaviyo provides extensive SMS analytics, including attributed SMS revenue, revenue per recipient, campaign and flow revenue, conversions and performance over time.

It also offers SMS Spend and SMS ROI metrics for eligible customers, allowing merchants to compare messaging expenditure with attributed revenue.

Klaviyo's attribution model is more sophisticated and configurable than a simple SMS-only view. Its default SMS conversion window is five days, and its broader platform is designed to help marketers understand performance across multiple channels.

That's valuable for marketing teams that want deeper attribution and cross-channel analysis.

The trade-off is complexity. Merchants whose primary question is simply "What did I spend on SMS and what did I get back?" may not need the breadth of analytics and marketing functionality Klaviyo provides.

Pricing

Klaviyo offers a free tier for small lists, but SMS is billed separately on a pay-as-you-go model. Paid plans scale based on email contacts + SMS volume. Suitable for larger merchants who want unified channel management but may be less cost-effective. 

Klaviyo pros

• Email and SMS within one platform

• Sophisticated segmentation and personalisation

• Extensive Shopify integration

• Powerful automated flows

• Detailed SMS analytics

• SMS revenue attribution and ROI reporting for eligible customers

• Cross-channel customer data and reporting

• Large ecosystem and Shopify merchant base

Klaviyo cons

• Can become expensive as your customer database and messaging requirements grow

• More complex than a dedicated SMS platform

• SMS is one component of a much broader marketing suite

• Merchants primarily interested in SMS may pay for functionality they don't need

Choose Klaviyo if: Email and SMS need to operate as part of one sophisticated marketing ecosystem and cross-channel data and attribution are priorities.

4. Postscript: Best for SMS-first DTC brands

Best for: DTC Shopify brands that want a sophisticated, SMS-first marketing platform, particularly in North America.

Postscript is built heavily around ecommerce SMS marketing and has established a significant presence among Shopify merchants.

It supports promotional campaigns, automated flows, customer segmentation and conversational messaging, making it a strong alternative for brands that see SMS as a major customer retention and revenue channel.

Unlike broader marketing platforms, SMS is central to Postscript's proposition.

Pricing

Postscript uses a combination of platform pricing, messaging charges and carrier fees.

Its published plans include options ranging from an entry-level tier with a minimum monthly spend through to higher-priced Growth, Professional and enterprise plans. Per-message pricing generally decreases on higher tiers, while applicable carrier charges need to be considered when calculating the total cost.

That can provide attractive economics for high-volume US senders, although Australian merchants should be careful about directly comparing US headline message rates with Australian SMS pricing.

Postscript pros

• SMS-first platform

• Deep Shopify and ecommerce focus

• Strong automation and segmentation

• Conversational messaging capabilities

• Mature product with a substantial Shopify review footprint

• Designed for brands running SMS as a significant marketing channel

Postscript cons

• Strongest market focus is North America

• Platform, usage and carrier fees need to be considered together

• Less locally focused for Australian messaging requirements

• Adds another marketing platform if your email and customer journeys already live elsewhere

Choose Postscript if: You're a DTC Shopify brand, particularly in North America, that wants SMS to be a major standalone marketing channel.

5. Maestra: Best for SMS inside omnichannel journeys

Best for: Mid-sized and enterprise brands that want SMS, MMS and RCS working inside the same journeys as email, push and on-site personalisation.

Maestra builds SMS into automated journeys that also run email, push, messaging apps, on-site and in-app personalisation.

An abandoned-cart journey, for example, can follow an email with a push and then a text carrying a promo code or bonus points, and shoppers who return to the site see a matching pop-up. SMS can be triggered by any event – from a birthday or 30 days without a purchase to expiring loyalty points or an item a shopper viewed dropping in price.

Maestra is powered by a real-time customer data platform, so you can build segments with RFM, lifecycle stages, nested logic, computed fields, or custom attributes. They update on their own as shoppers browse, add to favourites, buy, or do anything else.

A Forward Deployed Marketer comes with every account to plan the SMS strategy with your team and build the journeys, at no extra cost. You work together in a shared Slack channel, with a strategy session on Zoom every week. Your marketer also digs into your numbers and how your business runs, then suggests what to improve or optimise and which hypotheses are worth testing next.

Maestra pricing

The plan starts at $1,550 USD/month, with per-message fees on top. It covers the real-time CDP for your first 100,000 active customer profiles, SMS, MMS and RCS messaging, AI product recommendations, reporting and a named Forward Deployed Marketer. Billing is month-to-month, with no setup fees or lock-in terms.

Maestra pros

• SMS shares journeys with email, push, messaging apps, in-app and on-site offers

• Advanced segmentation on any customer data

• MMS and RCS carry AI recommendations

• Configurable attribution

• MCP connector to query your data from ChatGPT or Claude

• Tap-to-Text, double opt-in, opt-out detection and sender names registered with local carriers

• Forward Deployed Marketer included, working like part of your team from strategy to tests

Maestra cons

• No free plan or trial

• More focused on the US and Canada than on Australia

• Built for mid-sized and enterprise brands rather than small stores

Choose Maestra if: You want SMS to be one step in journeys with email, push and on-site offers, built with a dedicated marketer.

What should you look for in a Shopify SMS marketing app?

Before choosing a platform, consider more than the price of an individual SMS.

Direct Shopify integration

Look at how the SMS platform actually connects with Shopify.

A direct integration can make it easier to synchronise customer and order information, trigger automations and attribute purchases without introducing an additional integration platform.

Kudosity, Klaviyo, Maestra and other leading platforms connect directly with Shopify, while some SMS providers may require merchants to connect through middleware such as Zapier.

Revenue attribution

SMS engagement metrics don't tell the whole story.

Knowing that a message was delivered or clicked is useful, but merchants also need to understand whether their SMS activity is contributing to sales.

Look for platforms that connect messaging activity with Shopify purchases and allow you to evaluate revenue and ROI at campaign level.

It's also worth checking how attribution is calculated. A longer attribution window will generally associate more conversions with marketing activity, while a shorter window provides a more conservative view of the relationship between a message and a subsequent purchase.

No attribution model can prove that a single marketing touchpoint caused a purchase, so merchants should understand the methodology rather than comparing attributed-revenue numbers from different platforms at face value.

SMS pricing

Headline prices can be misleading.

Depending on the provider, your total cost may include:

• Platform subscriptions

• Per-message charges

• Carrier fees

• Usage minimums

• Subscriber or profile costs

• Premium features

Australian merchants should also check whether pricing is quoted in AUD or USD.

Automation

SMS becomes much more powerful when it responds automatically to customer behaviour.

Look for capabilities such as:

• Abandoned-cart recovery

• Welcome messages

• Birthday campaigns

• Post-purchase communication

• Win-back campaigns

• Transactional notifications

Australian messaging requirements

If you're based in Australia and messaging Australian customers, choose a provider that understands the local regulatory environment.

Businesses need to consider consent, sender ID and unsubscribe requirements, as well as the new SMS rules in Australia.

Having a provider with local messaging expertise can make it easier to understand and adapt to these requirements.

Support and infrastructure

SMS is ultimately a telecommunications channel, not just a marketing feature.

Consider where your provider operates, its carrier relationships, platform reliability, data residency, security certifications and whether support is available when you need it.

These factors become increasingly important as message volumes grow.
