Mst: Wishlist + Marketing Flow vs Listr: Wishlist + Reminder

Introduction

Choosing the right wishlist app is a surprisingly strategic decision for Shopify merchants. Wishlists can recover abandoned interest, create urgency, and feed personalized marketing — but the wrong choice adds maintenance overhead and missed revenue. Two popular options, Mst: Wishlist + Marketing flow and Listr: Wishlist + Reminder, promise wishlist functionality with marketing add-ons; both are lightweight and focused, yet they take different approaches to features, pricing, and integrations.

Short answer: Mst: Wishlist + Marketing flow is a strong pick for stores that want a simple, low-cost wishlist with deep customization and multi-channel alerts, while Listr: Wishlist + Reminder fits merchants who prioritize automated reminder cadence and social proof at a low entry cost. Both can be useful on lean stacks, but merchants seeking a single integrated retention platform that reduces app sprawl will find better value in a multi-tool solution.

This post provides a feature-by-feature, practical comparison of Mst: Wishlist + Marketing flow and Listr: Wishlist + Reminder so merchants can weigh trade-offs and match an app to business needs. The analysis uses available review data (150 reviews at 4.7 for Mst; 27 reviews at 4.3 for Listr) and published pricing/features. After the direct comparison, the article explains the limits of single-purpose apps and introduces a consolidated alternative designed to increase retention with less operational overhead.

Mst: Wishlist + Marketing flow vs. Listr: Wishlist + Reminder: At a Glance

Deep Dive Comparison: Features, Pricing, Integrations, and More

Feature Sets: What Each App Actually Does

Core wishlist functionality

Mst: Wishlist + Marketing flow centers on a fully customizable wishlist UI. It supports multiple wishlists per user, guest wishlists, unlimited items, and a My Wishlist page that can be edited via Liquid, HTML, and CSS. That degree of template-level access is useful for merchants who want the wishlist to match a brand's theme and layout.

Listr: Wishlist + Reminder focuses on simplicity and behavioral recovery. It offers no-signup wishlists, social sharing, and an emphasis on reminders and social proof metrics — for example, showing how many other customers added the same product to their wishlist.

Practical difference: Mst provides more control over presentation and user experience; Listr prioritizes straightforward social proof and automated reminders.

Price-drop and back-in-stock alerts

Mst includes price-drop and back-in-stock alerts via email, SMS, and push — a useful triage for recovering buyers across channels. The multi-channel approach lets merchants route alerts through existing tools (e.g., PushOwl, Brevo).

Listr sends price-drop emails when items in wishlists go on sale and notifies customers when product prices change. Listr is optimized for email reminders and sale-triggered outreach.

Practical difference: Mst is stronger for omnichannel recovery; Listr is solid for email-first re-engagement.

Reminders, cadence, and automation

Mst provides marketing flow capabilities tied to wishlist behavior and integrates with automation platforms such as Klaviyo and Shopify Flow — enabling custom flows when wishlist events occur.

Listr offers built-in daily/weekly/monthly reminder emails and customizable templates on its Premium plan. For merchants that want out-of-the-box reminder cadence without setting up email automation tools, Listr reduces setup time.

Practical difference: Listr is quick to enable reminders; Mst scales better when merchants already use automation platforms and want tailor-made flows.

Social proof and urgency features

Listr explicitly surfaces how many customers have wishlisted a product, a direct type of social proof that can boost conversion when displayed on product pages. It also provides top-wishlisted product lists to support merchandising.

Mst's materials mention sharing, but social proof widgets (e.g., “X people added this item”) are not emphasized as first-class in the published description. Mst’s advantage is more on customization and multi-list management than explicit social counters.

Practical difference: Use Listr when the goal is social proof-driven uplift; use Mst when UI flexibility and list management are the priority.

Customization and developer-friendliness

Mst exposes Liquid templates, HTML, and CSS for the wishlist page and supports API and headless themes. This appeals to merchants with custom themes or developers who want tight integration.

Listr offers customizable wishlist icons and pages and customizable email templates on Premium, but headless/API support isn't highlighted. For merchants that lack developer resources, Listr’s simpler customization may be sufficient.

Practical difference: Mst is the better fit for stores with design or dev teams needing full control.

Analytics and reporting

Listr lists analytics and reports as features, which helps merchants track top wishlisted items and email effectiveness. The reporting scope is focused on wishlist behavior.

Mst integrates with analytics workflows through Klaviyo and Shopify Flow, letting merchants capture wishlist events into existing analytics and reporting stacks. This means reporting depth depends on how the merchant wires wishlist events into their analytics tools.

Practical difference: Listr offers built-in quick insights; Mst delivers richer analytics when combined with a merchant’s existing BI or email tools.

Pricing and Value: Comparing Cost Per Feature

Mst: Pricing profile and value

Mst’s single published plan is priced at $2 / month. The description indicates “one fixed cost for all features” and no limits on items or customers. At this price, Mst represents strong value for merchants who want:

• Unlimited wishlist size and users
• All functionality unlocked without feature gating
• Customization and headless support at a minimal recurring cost

Value considerations: When a merchant values customization and unlimited use cases for a minuscule monthly fee, Mst represents excellent value for money. However, $2/month assumes merchants will handle additional needs (segmentation, advanced marketing, cross-app automation) with other tools.

Listr: Pricing profile and value

Listr offers a Free tier and a Premium tier at $4.99 / month.

The Free plan includes limits (up to 100 items added to wishlist, up to 100 wishlist emails) but is effective for testing wishlist behavior without cost. Premium unlocks unlimited items and emails, price-drop alerts, and customizable templates.

Value considerations: Listr’s free tier lowers the barrier to experimentation. For merchants who want a low-cost test or prefer built-in email reminders without wiring to Klaviyo, Listr’s paid tier is competitive value for money. For stores that outgrow free limits, the $4.99 price remains affordable compared to full marketing stacks.

Comparing cost against operational overhead

Both apps are inexpensive compared to bigger marketing suites, which is the point for many small stores. But cost per feature is not the only metric. Some relevant trade-offs:

• App sprawl: Adding either app adds another vendor to manage. For stores using multiple single-purpose apps, developer hours multiply during theme updates and troubleshooting.
• Hidden costs: If email reminders require a paid ESP (email service provider) or SMS credits, overall cost rises.
• Opportunity cost: Single-purpose apps don't bundle loyalty, referrals, reviews, and VIP programs. Merchants seeking integrated retention should compare aggregate cost and maintenance versus a unified platform.

Integrations: How Each App Plays With Other Tools

Mst integrations

Mst lists compatibility with Customer accounts, Shopify Flow, Klaviyo, Brevo (email), PushOwl/Brevo (push & SMS), and Apploy mobile builder. This set supports multi-channel messaging and automation, enabling wishlist events to feed into robust email flows.

Practical implication: Stores that already use Klaviyo or Shopify Flow benefit from Mst’s event hooks to create segmented campaigns, cross-sell flows, and triggered messages.

Listr integrations

Listr’s public notes emphasize compatibility with product filter apps and the ability to send email reminders. Listr’s focus is on in-app reminder workflows and social features rather than broad third-party automation.

Practical implication: Merchants relying heavily on an ESP for segmentation may need to export wishlist data or maintain separate integrations; Listr is easier if the merchant wants an integrated reminder feature without external mail flows.

How integrations impact long-term operations

Integrations matter more as the merchant scales. When the merchant relies on multiple data sources, apps that support event forwarding and API or Shopify Flow hooks will be easier to incorporate into lifecycle marketing. Mst’s explicit links to Klaviyo and Shopify Flow make it a stronger choice for merchants who plan to build complex, data-driven lifecycle campaigns.

User Support and Reliability

Mst: Support signals

Mst has a high rating (4.7) across 150 reviews, which suggests consistent user satisfaction. The developer (Mascot Software Technologies Pvt. Ltd) provides support resources and integrates with common merchant tools. A larger review base usually correlates with more resolved edge-case bugs and product maturity.

Listr: Support signals

Listr has a 4.3 rating across 27 reviews. The smaller review volume may indicate a younger app or a narrower user base. Listr’s documentation emphasizes built-in reminder features, which minimizes support requests around integrations but may require help if merchants want custom behavior beyond the app’s defaults.

Practical implication: For merchants that prioritize vendor responsiveness and a track record of continuous improvement, Mst’s higher review count and rating give confidence. Listr may still offer responsive support but with a smaller public footprint.

UX, Onboarding, and Setup

Mst onboarding

Mst emphasizes “easy app setup” while offering template-level controls. For stores that want to match theme styling, onboarding may involve theme edits or developer time. The payoff is a wishlist that visually integrates with the store.

Listr onboarding

Listr is designed to be straightforward: install, add wishlist widget, and enable reminders. The Free tier allows testing without configuration of external services, reducing time-to-value.

Practical implication: A lean store with no developer resources benefits from Listr’s simplicity. Merchants with designers or bespoke themes will appreciate Mst’s customizability despite slightly more initial work.

Mobile Experience and Guest Wishlists

Both apps advertise responsive designs and guest wishlist support. Guest wishlists remove the friction of account creation and increase adoption, particularly on mobile.

Mst explicitly mentions responsive behavior on desktop and mobile and supports guest users. Listr also supports no-signup wishlists and shareable links, which can speed sharing via mobile apps and social.

Practical difference: Both are comparable for mobile-first experiences, but Mst’s multiple wishlist support can create more advanced mobile UX (e.g., separate wishlists for gift ideas vs. personal favorites).

Social Sharing and Viral Features

Listr emphasizes shareable wishlist links and social sharing, adding viral potential to product discovery. The “how many others wishlisted this item” widget is built to increase curiosity and FOMO.

Mst mentions wishlist sharing but centers on customization and multi-list management rather than explicit social counters.

Practical difference: Listr is the more tactical choice for social sharing and direct social proof; Mst suits merchants who want a branded wishlist experience that can be amplified through custom share flows.

Reporting, Segmentation, and Use of Data

Listr provides built-in analytics for wishlist performance. For stores that want immediate insights into popular items, Listr’s reporting is convenient.

Mst’s strategy is to surface wishlist events into existing tools (Klaviyo, Shopify Flow), enabling merchants to build custom segments and report with the same analytics stack used for orders and lifecycle metrics.

Practical difference: Use Listr for quick, app-level reporting; use Mst if the merchant wants wishlist events routed into a central analytics system.

Scalability, Internationalization, and Enterprise Considerations

Mst supports multi-language and multiple currency stores and includes API/headless theme support — features that align with scaling merchants and enterprise builds.

Listr’s documentation does not emphasize multi-currency or headless APIs. It is positioned more toward smaller stores or non-headless architectures.

Practical difference: Merchants planning international expansion or headless implementations will benefit from Mst’s explicit support.

Security, Data Ownership, and Compliance

Both apps rely on Shopify’s platform for core data handling and should adhere to Shopify’s app security expectations. Merchants should verify:

• Data export options for wishlist events
• Compliance with local data privacy laws when sending email/SMS
• How long wishlist data is retained and how it can be deleted

Mst’s integration with workflow tools often means wishlist events are stored in ESPs or external analytics, which can give merchants more control over data retention. Listr maintains built-in reminders and stored analytics, so merchants should confirm export capabilities if data portability is required.

Maintenance, Theme Upgrades, and Long-Term Costs

Single-purpose wishlist apps reduce initial cost and complexity, but theme updates, Shopify version changes, and customizations can create maintenance cycles that compound across multiple apps.

Mst’s reliance on template edits and developer touchpoints means upgrades could require occasional work. Listr’s minimalistic approach often reduces theme conflicts, but scaling functionality may eventually require replacing single-purpose features with more integrated tools.

Practical difference: Consider the number of apps and future feature needs. Distributed single-purpose apps can become costly in developer time.

Where Each App Excels — Practical Use Cases

Mst: Wishlist + Marketing flow is a solid choice when the merchant:

• Wants full visual control (Liquid, HTML, CSS) over the wishlist page and widgets.
• Needs unlimited wishlist items and no per-customer caps at a very low monthly fee ($2).
• Plans to route wishlist events into Klaviyo, Shopify Flow, or other automation tools for custom lifecycle marketing.
• Operates multi-language or multi-currency storefronts or has headless architecture.

Listr: Wishlist + Reminder is a strong fit when the merchant:

• Wants quick-to-launch wishlist reminders and social proof with minimal setup.
• Prefers to test wishlist behavior using a Free tier before committing.
• Prioritizes built-in reminder cadence (daily/weekly/monthly) and shareable wishlist links.
• Seeks a low-touch solution for small-to-medium stores that don’t need deep theme customization.

Trade-offs and Potential Deal-Breakers

• If a merchant needs omnichannel alerts (email + SMS + push) and is ready to manage the routing through multiple platforms, Mst’s multi-channel features and integrations deliver a clear advantage.
• If a merchant has limited email infrastructure and wants immediate reminder functionality without external ESP setup, Listr’s built-in reminders and free tier reduce friction.
• For merchants on Shopify Plus, headless builds, or large catalogs with global storefronts, Mst’s API and multi-language support is more future-proof.
• Merchants seeking to consolidate loyalty, reviews, referrals, VIP tiers, and wishlists into a single retention strategy should evaluate integrated platforms to avoid app sprawl.

Implementation Checklist: Questions Merchants Should Ask Before Installing

• Is the wishlist data going to be routed into an email platform or kept within the app?
• Are multi-language and multi-currency support required now or in the next 12 months?
• Does the store need headless or API support for wishlist events?
• How important is social proof (count of others who added the item) to the product page experience?
• Is the merchant prepared to manage theme edits, or is a plug-and-play solution preferred?
• What are the long-term costs of adding separate tools for loyalty, referrals, and reviews?

Answering these will determine whether a focused wishlist app or a broader retention suite makes more sense.

The Alternative: Solving App Fatigue with an All-in-One Platform

Single-purpose apps are useful: they solve a specific problem quickly and cheaply. However, the more single-purpose tools a merchant installs, the greater the risk of “app fatigue” — operational overhead caused by multiple vendors, fragmented data, and more frequent theme conflicts. App fatigue drains developer time, complicates data analysis, and increases the chance of inconsistent customer experiences across touchpoints.

Growave’s philosophy, "More Growth, Less Stack," addresses this by offering an integrated retention suite that bundles wishlist functionality with loyalty, referrals, reviews, VIP tiers, and more. Instead of stitching together wishlist events, email reminders, and loyalty rules across different apps, a unified platform centralizes data, reduces maintenance, and accelerates long-term growth.

• For merchants who want to consolidate retention features and reduce app sprawl, consider how a single platform can streamline flows such as wishlist-to-loyalty conversion and wishlist-triggered rewards. Consolidating retention features can reduce time spent on debugging cross-app issues and consolidates reporting in one place. Consult the Growave pricing page for plan comparisons and an overview of available tiers: consolidate retention features.
• Wishlist activity often feeds loyalty and referral programs. Using a single provider removes the need for custom webhooks or middleware to award points when wishlist events convert. Explore how merchants can build loyalty and rewards that drive repeat purchases.
• Reviews and user-generated content amplify the value of wishlists: social proof strengthens conversion when customers see both wishlists and authentic product feedback. Growave enables merchants to collect and showcase authentic reviews, which pairs well with wishlist-driven merchandising.
• For merchants on Shopify Plus or considering headless architectures, an integrated platform provides enterprise-level features like checkout extensions and API support without the maintenance overhead of numerous apps. See available options for solutions for high-growth Plus brands.

Because integrated platforms centralize event tracking, reporting and segmentation become simpler. For example, wishlisted items can be automatically included in loyalty rules, in-app messages, or review requests without the need for separate integrations. That reduces the steps required to turn passive interest into repeat purchases and increases customer lifetime value.

Growave is available on the Shopify App Store and can be added directly to a Shopify storefront. Merchants evaluating a migration from multiple single-purpose apps often test the install and map wishlist events into consolidated workflows. To install a unified retention suite, consider a quick check of how Growave integrates across channels: install a unified retention suite.

Growave’s platform is designed to minimize future app additions by offering these capabilities in one place:

• Loyalty programs with customizable points and rewards, tiered VIP programs, and referral mechanics to encourage word-of-mouth.
• A wishlist module that works together with loyalty and referral logic, so wishlist conversions can automatically feed rewards.
• Reviews and UGC tools to bolster product pages and conversion rates.
• Referral campaigns and VIP tiers that amplify both retention and acquisition.
• Enterprise-friendly features like APIs, checkout extensions, and dedicated launch support for high-volume merchants.

For practical comparisons, the Growave site details feature sets and pricing to determine whether consolidation represents better value for money than maintaining multiple single-purpose apps: consolidate retention features. Merchants looking to see the platform in action can review customer examples and success stories: customer stories from brands scaling retention.

Growave’s wishlist functionality is only part of the broader retention equation. Combining wishlists with loyalty, referrals, and reviews creates compound effects on retention and average order value that single-purpose apps struggle to produce without significant integration work. For merchants that want to compare app-level costs and the operational burden of multiple vendors, the decision to consolidate often pays back in reduced developer time and more consistent customer experiences. For merchants wanting an immediate point of contact, Growave can also be added through the Shopify App Store: add Growave to Shopify in one click.

Growave combines the wishlist behavior that Mst and Listr capture with additional retention levers so merchants can convert interest into repeat purchases and lift customer lifetime value without maintaining a growing list of single-purpose apps. For merchants considering migration or consolidation, the Growave pricing and plan comparison helps determine which tier fits current order volumes and features: consolidate retention features.

How consolidation reduces friction (operational examples)

• Unified event architecture: Wishlist adds can trigger the same rule engine that awards loyalty points or initiates review requests, removing duplicate event wiring.
• Centralized reporting: One dashboard for wishlists, loyalty metrics, referral performance, and reviews shortens analysis cycles and clarifies which programs drive retention.
• Single support channel: Instead of coordinating between multiple vendors when a theme update breaks wishlist behavior, merchants have one support team that understands cross-feature dependencies.
• Lowered risk of broken flows: When a price-drop event needs to trigger multiple actions (email, SMS, loyalty points), a single platform ensures those actions are coordinated rather than tethered to multiple apps with separate queues and error modes.

Repeated links for merchants evaluating consolidation:

• Compare plans and features to calculate total cost of ownership: consolidate retention features.
• See how wishlist behavior can award rewards and boost repeat buyers: loyalty and rewards that drive repeat purchases.
• Pair wishlist activity with product reviews to increase conversion intent: collect and showcase authentic reviews.

Migration and Change Management: Moving from Single Apps to an Integrated Suite

Merchants considering consolidation should plan a migration with minimal customer disruption.

Key steps to consider:

• Inventory existing apps: List wishlist, loyalty, referral, review, and any automation tools currently in use.
• Map events: Identify the wishlist events to preserve (adds, removes, shares, price-drop triggers).
• Decide on phased migration: Start by routing wishlist events into the integrated platform while maintaining the old app in read-only mode to verify parity.
• Test flows: Validate that email reminders, price-drop alerts, and loyalty awards trigger properly in staging before diverting production traffic.
• Communicate to customers: If guest wishlists or shared links change, provide clear instructions to customers to preserve access or migrate data where possible.
• Monitor metrics: Track wishlist growth, reminder open rates, conversion rates, and changes in retention or repeat purchases.
