For many Shopify store owners, the struggle to minimize cart abandonment and maximize average order value (AOV) can feel like trying to catch water with a sieve. While popular platforms like Omnisend and Brevo (formerly Sendinblue) are household names in retention marketing, an entire suite of high-performing—but underrated—email and SMS tools are helping businesses capture more revenue with less noise and often lower cost.
TL;DR: Several lesser-known email and SMS tools offer powerful automation, segmentation, and A/B testing features ideal for Shopify merchants. While Omnisend and Brevo are effective, alternatives like Recart, Postscript, and Drip boast higher engagement through personalized flows and SMS optimization. These tools often integrate seamlessly with Shopify and include cart recovery, upsell sequences, and advanced analytics. Don’t overlook them when strategizing to strengthen your customer retention and boost average order value.
Why Go Beyond the Giants?
Big names like Omnisend and Brevo deliver solid performance, but they aren’t necessarily tailored for every store’s niche or growth phase. Their all-in-one nature can be limiting when you need highly customizable solutions or a bigger bang for your buck in SMS outreach. The market is now full of emerging or overlooked tools that offer laser-focused functionalities aligned with behavioral triggers, allowing Shopify sellers to rescue abandoned carts and inflate average spend per customer like never before.
Here are the top 6 underrated email + SMS tools Shopify store owners are using in 2024 to get results where big players sometimes fall short:
1. Recart – SMS-First Cart Recovery for Mobile-Heavy Audiences
Why it’s underrated: Many email marketing platforms treat SMS as an afterthought. Recart flips that narrative by focusing on mobile-first communication, which is especially effective for younger, mobile-heavy segments.
Key Features:
- Purpose-built SMS flows timed precisely around cart abandonment windows
- Easy opt-in collection through pop-ups and Facebook Messenger
- Real-time cart integration with dynamic product data
Recart claims that its clients see up to 61% more revenue recovered than with email-only flows. Combine SMS with personalized product recommendations, and you have a much more interactive experience than email alone can provide.
2. Klaviyo (Still Underrated When Fully Customized)
Why it’s underrated: Despite being a recognized player, Klaviyo is often underutilized. Many Shopify users fail to tap into its advanced segmentation and event-driven tactics—its real power lies in using its full potential.
Key Features:
- Behavioral email flows triggered by cart dwell time, product views, or discount interactions
- Dynamic SMS and email combined flows with RFM segmentation (Recency, Frequency, Monetary)
- Predictive analytics for expected future value and churn
In expert hands, Klaviyo becomes a retention powerhouse. When integrated meaningfully with Shopify’s backend data, it creates highly granular, hyper-personalized messages proven to increase AOV through cross-sells and time-sensitive incentives.
3. Postscript – Built for SMS and Shopify at the Core
Why it’s underrated: While Postscript is gaining traction, it’s still overshadowed by more general marketing platforms. But for SMS-based marketing tailored to Shopify, few tools come close in quality or usability.
Key Features:
- 100% Shopify-native integration without third-party bridges
- Click-level analytics to A/B test your SMS offers or reminders
- Support for two-way texting to create concierge-level customer experiences
One unintended benefit Postscript offers is brand intimacy—through conversational flows, customers feel directly supported and nudged, rather than broadcasted to. Brands using two-way SMS flows report significant increases in return rates and upsell effectiveness post-cart abandonment.
4. SmartrMail – Simplified Automation for Smaller Teams
Why it’s underrated: Not every Shopify store can afford a dedicated retention team. SmartrMail offers streamlined automation flows for abandoned cart, welcome series, and product recommendations, with a learning curve fit for solopreneurs or lean teams.
Key Features:
- Drag-and-drop email builder optimized for Shopify templates
- Pre-made abandoned cart and post-purchase flows
- Customer lifecycle metrics to adjust flow timing and frequency
For those seeking an affordable but still intelligent solution, SmartrMail is a go-to that doesn’t sacrifice features for ease of use. It’s a quiet standout among independently run Shopify stores trying to bootstrap their way to higher traction.
5. Drip – Visual Automations That Understand Buyer Psychology
Why it’s underrated: Drip offers unusually advanced visual workflows that work brilliantly for lifecycle marketing, yet it’s less talked about than bigger alternatives. Its strongest use case is mapping customer journeys after the initial abandonment phase.
Key Features:
- Visual “if-this-then” tree with customizable delays and conditions
- Native support for Shopify product feeds and behavior tracking
- Progressive profiling for long-term customer understanding
Drip has been particularly effective for multi-SKU stores where personalization across dozens of categories is challenging. The workflow builder allows marketing teams to split and test up to micro-level triggers that correspond with customer behavior, seasonality, or product affinity.
6. Cartloop – Real-Time Cart Recovery via Live Agents
Why it’s underrated: Cartloop isn’t a bulk tool. Its edge lies in human-powered SMS cart recovery. A real person converses with your abandoning customer in real time, offering assistance, product knowledge, or even custom incentives.
Key Features:
- Live agents send SMS to hesitant shoppers within minutes of carting
- Recovery messages that feel consultative, not automated
- Built-in escalation when a user is undecided or price-shopping
Though higher-touch and slightly more expensive per contact, the ROI per recovered cart can be significantly higher than traditional flows—especially for high-ticket or niche products that require buyer confidence to convert.
Choosing the Right Tool for Your Brand
It’s not about finding the flashiest tool—it’s about alignment. Here’s a quick breakdown of what to choose based on your primary objective:
- Want high SMS engagement? Try Recart or Postscript.
- Need holistic automation? Go with Klaviyo or Drip.
- Just getting started? Lean into SmartrMail.
- Want white-glove service for your cart abandoners? Cartloop is your best bet.
Moreover, all these tools integrate directly or through APIs with Shopify, making implementation straightforward and scalable as your store grows. Each of them also supports experimentation, enabling merchants to fine-tune flows that genuinely move the needle on cart recovery and AOV.
Final Thought: It’s Time to Diversify
Changing your email+SMS toolkit won’t magically triple your revenue overnight—but choosing a solution tailored to your store model, buyer persona, and product type can lead to steady improvements in both cart recovery and overall customer value. With rising acquisition costs, your retention marketing stack is where you’ll gain or lose momentum.
Start testing. Start segmenting. And most importantly, start thinking beyond the default options everyone’s using.
