ESC Wishlist + Save for Later vs. Smart Wishlist: An In-Depth Comparison

Introduction

Choosing the right wishlist app is a common decision point for merchants building a shopping experience that converts browsers into buyers. Wishlist functionality can increase average order value, recover stalled purchases, and help merchants understand customer intent — but not all wishlist apps are created equal. The choice between a lightweight, focused tool and a more robust, flexible product can affect conversion, site performance, and long-term growth.

Short answer: ESC Wishlist + Save for Later is a very small, focused option that can work for merchants who need a single, simple save-for-later widget at minimal monthly cost. Smart Wishlist offers more features, guest wishlist support, and APIs for customization, and is better suited to stores that need reliability and flexibility at a modest price. For merchants who want to reduce tool sprawl and access wishlists as part of a retention stack (loyalty, referrals, reviews, VIP tiers), an integrated platform like Growave delivers better value for money and long-term outcomes.

This post provides a detailed, feature-by-feature comparison of ESC Wishlist + Save for Later and Smart Wishlist to help merchants decide which app fits their current priorities and growth plan. After an objective evaluation, the article introduces an integrated alternative designed to reduce the number of single-purpose apps in the store.

ESC Wishlist + Save for Later vs. Smart Wishlist: At a Glance

Deep Dive Comparison

This section examines the two apps across practical criteria merchants evaluate: feature set, pricing and value, integrations, implementation and theme compatibility, performance and reliability, data ownership and privacy, support and documentation, and the business outcomes each app helps deliver.

Features

Core Wishlist Capabilities

ESC Wishlist + Save for Later implements the basic use case: give customers a way to save items and surface those saved items at the cart so returning shoppers see them before checkout. The app advertises unlimited wishlists and social sharing.

Smart Wishlist provides more comprehensive wishlist functionality out of the box. It places wishlist buttons across product, collection, search result, and cart pages and supports both guest and logged-in users. It also includes APIs (Javascript and REST) for advanced customizations.

Key implications for merchants:

• ESC is focused on the cart/save-for-later workflow. That can be effective for reducing cart abandonment driven by indecision, because saved items appear near checkout.
• Smart Wishlist addresses discovery and browsing behavior (collection and search results) in addition to the cart, increasing the chance of capturing intent earlier in the funnel.
• Guest support in Smart Wishlist removes friction for users who aren’t logged in — a notable win for conversion.

Sharing and Social Features

Both apps include sharing options to let customers share lists with friends. ESC promotes free social sharing as a way to increase brand reach. Smart Wishlist includes sharing plus APIs that can be wired to custom social workflows or email captures.

For social-driven stores, Smart Wishlist’s flexibility is an advantage because it enables deeper integrations with email or marketing flows; ESC’s sharing is adequate but more limited.

Customization and Theming

ESC advertises a “broad range of options for customizing how the app looks on your store.” For stores that need a specific look-and-feel with minimal development, that may be sufficient.

Smart Wishlist emphasizes a lightweight payload and promises not to break the theme upon uninstall. It also exposes APIs for shops that want to programmatically control appearance and behavior. That makes Smart Wishlist a safer bet for stores with custom themes, page builders, or those planning to evolve the product experience.

Advanced Needs: APIs and Extensibility

Smart Wishlist includes Javascript and REST APIs, which is a meaningful differentiator for merchants expecting to tie wishlist behavior into other systems (CRM, custom analytics, or headless storefronts). ESC does not advertise APIs in its listed description.

When the roadmap includes custom triggers (e.g., reward points when a wishlist item is added, or sending abandoned-wishlist automations), Smart Wishlist’s APIs make those workflows achievable without replacing the wishlist app.

Pricing & Value

Both apps are positioned as low-cost options.

• ESC Wishlist + Save for Later charges $5 per month.
• Smart Wishlist lists a Standard plan at $4.99 per month.

For price-sensitive merchants who only need wishlist functionality, both are similar and affordable. The question is value, not sticker price.

Considerations on value for money:

• Feature depth per dollar: Smart Wishlist includes guest support and APIs at essentially the same price as ESC. That makes Smart Wishlist better value for stores that expect to scale wishlist usage or build custom flows.
• Support and ratings: ESC’s listing shows 2 reviews and a very low 1.0 rating, which raises concerns about support responsiveness and product reliability. Smart Wishlist has 81 reviews and a 3.6 rating, representing a broader sample and generally more stable performance in real-world stores.
• Long-term total cost: Merchants relying on wishlists as part of a broader retention strategy will likely add complementary apps (loyalty, referrals, reviews) over time. Each additional app increases monthly spend and complexity. An integrated platform can be better value as features are consolidated.

A pragmatic approach is to value the app not only on monthly cost but on outcomes: recovery of abandoned intent, contribution to repeat purchase rate, and developer time required to integrate or maintain the app.

Integrations & Ecosystem

ESC’s public listing does not highlight integrations beyond standard Shopify behavior. Smart Wishlist specifies integration compatibility with services like Sendgrid and ShareThis, and provides APIs for custom integrations.

Why integrations matter:

• Email and automation: If wishlists feed email flows (abandoned wishlist reminders, upsell messaging), integration with email providers reduces manual work and improves event accuracy.
• Marketing and analytics: Webhooks and APIs enable passing wishlist events into analytics, allowing merchants to measure wishlist-driven conversions.
• Headless or multi-channel storefronts: API access is essential when storefront logic doesn’t live in Shopify liquid templates.

In short, stores with existing marketing stacks (Klavyio, Omnisend, custom CRMs) will find Smart Wishlist easier to integrate. ESC could be adequate for stores that prefer a self-contained, simple widget and do not plan to route wishlist events to external systems.

Implementation & Theme Compatibility

Theme compatibility and ease of install are top pain points for merchants.

• ESC positions itself as customizable in appearance but does not highlight developer-friendly safeguards. With only 2 reviews and a 1.0 rating, there is limited public feedback on theme compatibility or uninstall behavior.
• Smart Wishlist stresses a lightweight payload and an uninstall process that doesn't break the theme. It also supports adding wishlist buttons to multiple page types without code in many cases.

For merchants using page builders (e.g., Pagefly, GemPages) or heavily customized themes, Smart Wishlist’s emphasis on not breaking themes and API access reduces the risk of costly fixes post-install.

Performance & Reliability

Performance impact and app stability directly affect conversion. Even small increases in JavaScript payload or slow network calls can reduce conversion rates.

• Smart Wishlist lists "Lightweight Payload" as a selling point, which signals attention to performance.
• ESC does not explicitly call out payload size or performance impact.

Given Smart Wishlist’s broader review base (81 reviews), performance claims are better validated in the real world than ESC’s claims, which have minimal public validation.

Data Ownership & Privacy

Wishlist apps collect user intent data that can be valuable. Key merchant questions include:

• Where is wishlist data stored?
• Is it exportable?
• How are guest lists reconciled with accounts?
• Are events suitable for segmentation in email or advertising platforms?

Smart Wishlist’s APIs make exporting and reconciling wishlist data more straightforward. ESC’s description does not specify export or data handling details, which can be a downside for merchants who rely on first-party data for personalization and measurement.

Support & Documentation

A common tradeoff with low-cost apps is limited support. Public review metrics provide signal:

• ESC: 2 reviews, 1.0 rating. Very limited feedback suggests merchants should be cautious and test support responsiveness before committing.
• Smart Wishlist: 81 reviews, 3.6 rating. Mixed but wider feedback indicates more merchant usage and a more established support process.

When evaluating wishlist apps, merchants should verify:

• Support SLA and channels (email, chat, phone)
• Availability of developer docs and API references
• Whether the app offers setup assistance or paid onboarding for larger stores

Security & Compliance

Both apps operate within the Shopify ecosystem and are subject to Shopify’s platform constraints. Merchants should confirm whether wishlist data is stored in compliance with applicable privacy regulations and if guest wishlist email collection complies with consent and spam laws.

Reporting & Analytics

Smart Wishlist’s API-based approach supports event tracking that feeds into analytics and attribution, enabling merchants to quantify wishlist impact on conversion and LTV. ESC does not advertise analytics capabilities or event exporting, which limits the ability to measure wishlist-driven revenue in detail.

Uninstall Behavior & Theme Clean-Up

Smart Wishlist claims uninstall safety — an important feature when testing apps. ESC’s listing does not clearly state whether the theme is cleaned up automatically on uninstall. Without that guarantee, merchants risk leftover code or broken templates.

Summary of Comparative Strengths

ESC Wishlist + Save for Later — Strengths

• Low-cost, simple pay-per-month model ($5).
• Focused save-for-later experience under the cart that can reduce last-minute abandonment.
• Unlimited wishlists and social sharing for a lightweight social push.
• Potentially quick to deploy for stores that only need cart-level save functionality.

ESC Wishlist + Save for Later — Weaknesses

• Minimal public reviews (2) and a low rating (1.0) raise reliability and support concerns.
• No advertised APIs, integrations, or advanced export capabilities.
• Unknown uninstall behavior and limited evidence of theme safety.

Smart Wishlist — Strengths

• Full wishlist coverage across product, collection, search, and cart pages.
• Guest and logged-in user support improves capture rates.
• Javascript and REST APIs for integrations and advanced workflows.
• Lightweight payload and uninstall safety claims reduce risk to site performance and themes.
• Larger review base (81 reviews) and a mid-level rating (3.6) provide more actionable social proof.

Smart Wishlist — Weaknesses

• Rating (3.6) indicates room for improvement in features or support.
• Limited public integrations listed (Sendgrid, ShareThis) — merchants may need to use APIs to connect other tools.

Use Cases: Which App Fits Which Merchant

• Stores with minimal technical resources and only an immediate cart-focused save-for-later requirement: ESC Wishlist + Save for Later is an uncomplicated, low-cost place to start. The cart-proximate saved items can convert indecisive shoppers with minimal configuration.
• Stores that want a full wishlist experience throughout the browsing journey, require guest wishlist support, or plan custom integrations (email flows, analytics, headless storefronts): Smart Wishlist is a stronger choice because of guest support, API access, and theme-safe claims.
• Stores planning a retention strategy that includes loyalty programs, referral incentives, and review capture should consider an integrated solution rather than adding a separate wishlist app to a stack. That alternative reduces monthly costs, avoids cross-app friction, and creates unified customer profiles.

Implementation Checklist: What Merchants Should Verify Before Installing

Before installing either app, merchants should validate the following items to avoid post-install problems:

• Confirm support channels and expected response times.
• Test theme backup and confirm uninstall cleanup behavior in a staging environment.
• If guest wishlists are essential, validate how guest-to-account reconciliation is handled.
• Determine how wishlist events will be exported or pushed to the marketing stack.
• Check the payload size and any asynchronous loading options to minimize performance impact.
• Ask about GDPR/CCPA compliance and data retention policies.

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

App fatigue is a real and growing problem for merchants. Each single-purpose app adds monthly cost, increases the number of vendor relationships to manage, and raises the risk of theme conflicts, performance degradation, and data fragmentation. Rather than buying, installing, and maintaining multiple single-function tools, many merchants benefit from consolidating core retention features into an integrated platform that centralizes loyalty, reviews, referrals, and wishlists.

Growave’s "More Growth, Less Stack" proposition addresses these pain points by combining wishlist functionality with loyalty and rewards, referrals, reviews & UGC, and VIP tiers. This reduces the number of apps and unifies customer data into a single retention engine.

Key advantages of an integrated approach:

• Unified customer profiles that link wishlist intent to loyalty behavior and review activity.
• Fewer integration points and less maintenance overhead.
• Shared incentives (e.g., rewarding points for adding items to a wishlist) without custom work across separate apps.
• Consistent brand UX across loyalty, reviews, and wishlist experiences.

Growave includes native loyalty tools that go beyond points and provide flexible reward actions and VIP tiers. For merchants looking to consolidate retention features, Growave enables the creation of loyalty and rewards that drive repeat purchases. That capability makes it possible to encourage wishlist actions through rewards without adding more apps.

Growave also handles reviews and UGC. Merchants can collect and showcase authentic reviews that influence product discovery and purchase decisions. Having wishlist and review data in the same platform improves personalization: wishlist signals can surface products with strong social proof, nudging customers to convert.

Practical ways an integrated platform changes outcomes:

• Convert saved intent faster: Loyalty triggers can apply points or discounts tied to wishlist activity, which increases the chance of converting saved items into purchases.
• Reduce refund and churn risk: Unified customer insights help identify repeat customers and reward them earlier, improving retention and lifetime value.
• Simplify analytics: Event streams delivered from one platform reduce the need to stitch together analytics from several vendors.

For merchants who want to see how consolidation works in practice, Growave presents product and pricing options that range from a free plan to higher-tier plans designed for high-growth stores and enterprise needs. For an overview of pricing and plans, see the page explaining consolidate retention features with a single plan.

How Growave Compares on the Same Criteria

When comparing Growave to the single-function wishlist apps, the following distinctions are notable:

• Features: Growave includes wishlist capabilities plus loyalty, referrals, reviews, and VIP tiers. Rather than adding separate modules, merchants get cross-feature functionality out of the box.
• Pricing & Value: While Growave’s entry price is higher than the single-purpose wishlist apps, the combined value covers several categories of tools that merchants would otherwise purchase separately. The product and pricing overview explains how a unified plan can be better value for money than buying multiple apps individually — view the plans to evaluate how consolidation reduces monthly spend.
• Integrations: Growave integrates with common tools and channels, lowering the integration burden. For merchants that rely on reviews as social proof, Growave includes native review workflows to collect and display customer feedback.
• Support & Scale: Growave provides tiered plans that include priority support and customer success for larger stores. For merchants scaling toward enterprise needs, information on multi-store and Plus capabilities can be found on the page describing customer stories and tailored Plus solutions.
• Data & Reporting: A consolidated event stream gives marketing teams a clearer picture of customer journeys from wishlist to purchase to loyalty.

Two Secondary Feature Links (Referenced Twice Each)

Growave’s loyalty capabilities are a primary retention lever and are detailed with practical examples of reward actions. Merchants evaluating consolidation should review the documentation about loyalty and rewards that drive repeat purchases to understand how wishlist actions can be incentivized.

Similarly, Growave’s reviews product helps brands capture and publish product feedback. For stores where social proof influences conversion, it’s helpful to review how to collect and showcase authentic reviews.

Both the loyalty and reviews pages provide real examples of how wishlist data can be used within a single platform to increase conversion and LTV, and they demonstrate why consolidation can be more efficient than maintaining multiple single-purpose apps.

Why Merchants Migrate Away From Single-Purpose Apps

• Hidden complexity: multiple apps mean multiple dashboards, billing cycles, and support relationships.
• Theme fragility: different apps can conflict and create maintenance overhead.
• Fragmented data: customer signals live in different systems, making personalization and attribution harder.
• Cost creep: small monthly fees add up quickly as features multiply.

Consolidation addresses these issues by centralizing features, aligning incentives, and simplifying vendor management. Merchants interested in exploring consolidation should consult the product and pricing page to evaluate which plan matches order volume and feature needs: see how plans scale with merchant growth. Merchants can also explore the Shopify App Store listing if they prefer to install from that marketplace: view the app listing to check compatibility and reviews on the store page, where Growave appears among solutions for retention: manage retention through a single app installation.

Migration Considerations

If a merchant decides to move from a single-purpose wishlist app to an integrated platform, the migration plan should address:

• Data export: ensure wishlist items, customer emails, and timestamps are exportable.
• Reconciliation: map old wishlist IDs to new customer profiles.
• Timing: plan a staged cutover to reduce the risk of lost events.
• Tracking: ensure analytics and email automations point to the new event sources.
• Communication: inform customers of any changes to sharing links or wishlist access.

Growave supports migrations and onboarding options depending on plan level; merchants evaluating migration should consider contacting support or requesting a demo to understand migration paths and assistance. A demo can clarify migration steps and expected timelines: merchants that want an expert walkthrough can book a personalized demo.

Practical Decision Framework

Merchants can use a simple, outcome-focused framework to decide:

• Priority is minimal cost and a cart-level save-for-later widget: ESC might be sufficient in the short term, but verify support responsiveness.
• Priority is breadth of wishlist features, guest support, and APIs for customization: Smart Wishlist provides more functionality and integration options for the same monthly threshold.
• Priority is retention, consolidated data, and reducing app sprawl: an integrated platform that includes wishlist, loyalty, reviews, and referrals offers better long-term value.

A focused test can help: install a wishlist app in a staging environment to measure performance impact, validate uninstall behavior, and simulate integration with marketing automations. For stores moving beyond experimentation into a scaled retention strategy, consolidating into a single platform reduces technical debt and improves analytics fidelity.

Cost of Ownership Comparison (Conceptual)

Monthly subscription is only a small part of total cost. Consider these ongoing costs:

• Monthly subscription fees for each app.
• Developer time to integrate and maintain multiple apps.
• Potential lost conversion if theme or performance issues arise.
• Opportunity cost of fragmented customer data that limits personalization.

When these factors are tallied, integrated platforms often deliver better value for money because they eliminate redundant subscriptions and smooth integration work.

Conclusion

For merchants choosing between ESC Wishlist + Save for Later and Smart Wishlist, the decision comes down to scope and future plans. ESC Wishlist + Save for Later offers a minimal, cart-focused save-for-later widget at a low monthly price; it may be appropriate for stores that need the simplest possible wishlist solution and accept the tradeoffs around limited public feedback and uncertain integrations. Smart Wishlist provides a more complete wishlist experience—one-click saving across product, collection, search and cart pages, guest wishlist support, and developer APIs which deliver more flexibility and better integration potential at a similar monthly price. Public review signals favor Smart Wishlist for stores that expect to grow wishlist use over time.
