Best Shopify Apps for Ecommerce: 5 Tools to Grow Your Online Store
Launching a Shopify store takes an afternoon. Running it well takes a stack of decisions nobody warns you about: which tool sends the abandoned cart email, where the reviews come from, who answers the “where’s my order” messages at 11 p.m., and whether Google can read your product pages at all.
That’s where the best Shopify apps for ecommerce earn their keep. The right app removes one specific bottleneck. The wrong one adds a monthly bill and a little more page weight for no measurable return.
This guide compares five Shopify apps that cover the jobs most stores hit first: email and SMS marketing, product reviews, customer support, post-purchase upsells, and image speed with on-page SEO. For each app you’ll see what it does, how its pricing works, where it falls short, and who should skip it.
The best Shopify apps for ecommerce depend on your biggest bottleneck. Klaviyo is the pick for email and SMS marketing, Loox for photo and video reviews, Gorgias for customer support, ReConvert (now Upsell.com) for post-purchase upsells, and TinyIMG for image speed and on-page SEO.
Start with the one app that fixes your most expensive problem, then add others only when your numbers say you need them.

1. Klaviyo — Best for Email and SMS Marketing
| Category | Email and SMS marketing platform |
| Works with | Shopify (native integration), plus review apps such as Loox |
| Best for | Stores with a growing customer list and repeat-purchase products |
| Ease of use | Moderate. Templates help; segmentation takes practice |
| Biggest limitation | Cost climbs as your active profile count grows |
What Is Klaviyo?
Klaviyo is an email and SMS marketing platform built around ecommerce data. It connects to Shopify, pulls in customer, order, and browsing activity, and triggers messages based on what shoppers actually do: view a product, abandon a cart, place a second order, or go quiet for months.
Why We Recommend It
Most Shopify stores leave money on the table in the same three places: abandoned carts, first-time buyers who never return, and past customers nobody follows up with. Klaviyo’s ready-made flows target exactly those gaps. The payoff is customer retention. Messaging people who already know your brand tends to cost less than winning a new customer from scratch, and it lifts customer lifetime value over time.
Key Features
- Pre-built flows for abandoned carts, welcome series, and post-purchase follow-ups
- Segmentation based on Shopify order history and on-site behavior
- Email and SMS managed in one platform
- Revenue reporting tied to specific campaigns and flows
- Signup forms and pop-ups for list growth
- Integrations with review, loyalty, and support apps
Pros and Cons
- ✓Strong Shopify data sync for targeted segments
- ✓Quick to launch core flows from templates
- ✓Email and SMS in one place
- ✓Reporting connects messages to revenue
- ✓Large integration ecosystem
- ✕Pricing rises as active profiles grow
- ✕SMS is billed separately from email
- ✕Segmentation has a learning curve
- ✕More depth than a tiny list needs
Pricing
Who Should Use Klaviyo?
Shopify merchants with a growing customer list, repeat-purchase products (beauty, coffee, supplements, pet supplies), or a plan to treat email and SMS as a real revenue channel.
Who Should Skip Klaviyo?
Brand-new stores with almost no list, or merchants who send an occasional newsletter and nothing else. A simpler, cheaper email tool is plenty at that stage. Also skip it if you can’t spend time building flows, because the value lives in the automation.
Our Verdict
2. Loox — Best for Photo and Video Reviews
| Category | Product reviews and social proof |
| Works with | Shopify, Klaviyo, Omnisend, Google Shopping |
| Best for | Product pages that need proof from real customers |
| Ease of use | Easy. No-code setup and widgets |
| Biggest limitation | Advanced features sit on higher tiers |
What Is Loox?
Loox is a Shopify reviews app focused on photo and video reviews. It emails customers after purchase, asks for a review, and displays the results on product pages, in carousels, and in pop-ups.
Why We Recommend It
Shoppers can’t touch your product, so they look for evidence that someone else already bought it and liked it. A photo from a real customer often convinces better than a polished product shot, which is why visual reviews matter for conversion rate. Loox is built around that idea, and its discount-for-photo-review option nudges more customers to include images.
If you also care about reviews beyond your own store, such as Google or third-party sites, our guides to customer review collection software and online reputation management software cover that wider picture. For replying at scale, see AI review response software.
Key Features
- Automated review request emails after purchase
- Photo and video review collection
- Discount incentive for customers who add photos
- Display options such as carousels and pop-ups
- Google Shopping integration
- Review request integrations with Klaviyo and Omnisend
- Referral tools on higher plans
Pros and Cons
- ✓Visual reviews build credibility fast
- ✓No-code install and widgets
- ✓Photo-review discount encourages richer submissions
- ✓Connects with email platforms and Google Shopping
- ✕Video reviews, Google Shopping, and referrals need a higher tier
- ✕Entry plan has order limits
- ✕Less natural for products that don’t photograph well
- ✕Incentivized reviews need clear disclosure
Pricing
Who Should Use Loox?
Stores selling products customers love to photograph: fashion, beauty, home, pets, and food and drink.
Who Should Skip Loox?
Low-volume stores that only need a basic free review widget, or merchants whose products aren’t visual. If you offer a discount for photo reviews, make sure you disclose the incentive clearly.
Our Verdict
3. Gorgias — Best for Customer Support at Scale
| Category | Ecommerce helpdesk and customer support |
| Works with | Shopify, BigCommerce, Magento 2 |
| Best for | Stores handling steady, repetitive ticket volume |
| Ease of use | Moderate. Rules and macros take setup time |
| Biggest limitation | Ticket-based pricing can climb quickly |
What Is Gorgias?
Gorgias is a helpdesk built for ecommerce. It pulls email, live chat, social messages, and SMS into one inbox and shows Shopify order details beside each conversation.
Why We Recommend It
Support questions repeat: where’s my order, can I change my address, how do I return this. A shared inbox that shows the customer’s order next to their message lets an agent answer in seconds instead of hopping between tabs. Macros and rules automate common replies, and Gorgias also offers an AI Agent for routine questions (confirm the current cost before you count on it).
Key Features
- One inbox for email, chat, social, and SMS
- Shopify order data inside each ticket
- Macros and rules that automate repeat replies
- Order actions, such as refunds or edits, from within the helpdesk
- Self-service tools like a help center and chat widget
- Reporting on response times and ticket volume
Pros and Cons
- ✓Cuts tab-switching for support agents
- ✓Automation handles repetitive questions
- ✓Built for ecommerce, not retrofitted
- ✓Scales as your team grows
- ✕Pricing is tied to monthly ticket volume
- ✕Overkill if you get a few messages a week
- ✕Automation needs setup time
- ✕AI features can add cost
Pricing
Who Should Use Gorgias?
Stores handling dozens of tickets a day, running a small support team, or selling products that trigger lots of order-status and return questions.
Who Should Skip Gorgias?
Stores that receive a handful of messages a week. A shared inbox works fine at that volume, and the extra monthly cost won’t pay for itself yet.
Our Verdict
4. ReConvert (Now Upsell.com) — Best for Post-Purchase Upsells
| Category | Upsell and cross-sell app |
| Works with | Shopify (including Shopify Plus checkout) and Wix |
| Best for | Raising average order value without more ad spend |
| Ease of use | Easy. Drag-and-drop offer and page editor |
| Biggest limitation | Fees rise with order volume or upsell revenue |
What Is ReConvert?
ReConvert is a Shopify upsell and cross-sell app. The company now operates under the Upsell.com name, but many merchants still know it as ReConvert. It adds one-click offers after checkout, customizes the thank-you page, and supports cart and product-page upsells.
Why We Recommend It
Your customer just paid. Trust is at its peak and their card details are already entered. A relevant one-click offer at that moment can raise average order value without another ad dollar. The thank-you page also stops being a dead end: you can add offers, surveys, and other prompts that encourage repeat purchases.
Key Features
- One-click post-purchase upsell funnels
- Drag-and-drop thank-you page builder
- Cart and product-page upsells and cross-sells
- Product bundle offers
- Checkout upsells for Shopify Plus stores
- Offer targeting and performance analytics
Pros and Cons
- ✓Free plan lets you test before paying
- ✓Quick to build offers without code
- ✓Thank-you page does more than say thanks
- ✓Analytics show which offers earn revenue
- ✕Checkout upsells are limited to Shopify Plus
- ✕Paid fees rise with order volume or upsell revenue
- ✕Results depend on offer quality
- ✕Rebrand can make the app harder to find by its old name
Pricing
Who Should Use ReConvert?
Stores with steady orders and products that pair naturally: accessories, refills, bundles, or add-ons.
Who Should Skip ReConvert?
Stores with very low order volume, or catalogs where nothing logically pairs with the main product. Merchant reviews on the Shopify App Store are mostly positive, but a few say it never paid for itself, so track results from day one.
Our Verdict
5. TinyIMG — Best for Image Speed and On-Page SEO
| Category | Image optimization and Shopify SEO |
| Works with | Shopify (installs from the Shopify admin) |
| Best for | Page speed and technical SEO housekeeping |
| Ease of use | Easy. No code required |
| Biggest limitation | Not a full SEO suite |
What Is TinyIMG?
TinyIMG is a Shopify app that compresses and resizes product images, optimizes filenames and alt text, manages SEO metadata, and flags common issues such as broken links. It also supports bulk redirects.
Why We Recommend It
Product photos are usually the heaviest thing on a Shopify page. Oversized images slow product pages, frustrate mobile shoppers, and can hold back organic traffic. TinyIMG tackles that first, then covers housekeeping most store owners never get to: alt text, metadata, 404 errors, and redirects.
When you’re ready to go beyond image and metadata cleanup, our guides to schema markup generators and structured data tools explain how rich results work, and our roundup of the best SEO tools covers research and tracking.
Key Features
- Automatic image compression and resizing
- Filename and alt text optimization
- SEO metadata management
- Site audit that highlights common SEO problems
- Broken link detection and bulk redirects
- 30-day image backups
Pros and Cons
- ✓Fixes one of the biggest Shopify speed drags
- ✓Free plan lets you test it first
- ✓Combines speed and basic SEO in one app
- ✓Backups make changes reversible
- ✕Not a replacement for keyword research or content strategy
- ✕Usage-based charges scale with image count
- ✕Automated alt text and metadata still need a human review
- ✕May overlap with other SEO apps you already run
Pricing
Who Should Use TinyIMG?
Stores with large catalogs, big product photos, and no developer on call.
Who Should Skip TinyIMG?
Stores that already compress images through a developer-built workflow or run a dedicated SEO suite. If you want to go deeper than image and metadata cleanup, look at structured data next.
Our Verdict
Which Shopify App Is Best for Your Store?
Fix the bottleneck that costs you the most right now. Here’s the shortcut:
Do You Actually Need Shopify Apps?
Short answer: you need fewer apps than the Shopify App Store wants you to think. Most stores do well with a few apps that each solve one specific problem, not a pile of overlapping tools.
- Too many apps can slow your store. Many apps load scripts on your storefront. Test page speed before and after every install.
- Costs add up. Several small monthly fees, plus usage-based charges, can quietly outgrow the revenue they produce.
- Some apps duplicate each other. A reviews app with referrals, an email platform with pop-ups, and a theme with built-in sections often do the same job.
- Every app needs a job. If you can’t name the number it should improve, you probably don’t need it yet.
- Remove what you don’t use. Uninstall unused apps, then check your theme for leftover code.
Pro tip: check what Shopify and your theme already include before you install anything. Built-in features cost nothing and don’t add third-party scripts.
A Simple Shopify App Stack for a Growing Ecommerce Store
What apps should every Shopify store have? A way to email customers, a way to collect reviews, fast images, and a plan for support. Beyond that, add apps only when a clear problem shows up. Here’s how that plays out by stage.
For a New Shopify Store
- Klaviyo: start with a welcome flow and an abandoned cart flow.
- TinyIMG: compress images and tidy alt text from day one.
- Loox: optional until your first real orders arrive.
Rule of thumb: Keep the stack tiny. You don’t have the order volume yet to justify anything else.
For a Growing Store
- Loox: turn happy buyers into photo and video social proof.
- ReConvert (Upsell.com): test one post-purchase offer once orders are steady.
- Klaviyo: expand into post-purchase and win-back flows.
Rule of thumb: Add one app at a time and measure it for a few weeks before adding the next.
For an Established Store
- Gorgias: join the stack once support volume demands a real helpdesk.
- Reviews to email: feed Loox review requests through Klaviyo for tighter timing.
- Upsells and SEO: keep ReConvert offers tuned and TinyIMG audits running.
Rule of thumb: Audit the stack every quarter and cut anything that no longer earns its fee.
Tracking how these tools affect traffic and revenue matters just as much as installing them. Our roundup of SEO reporting tools is a good place to start if you want to measure organic results.
Frequently Asked Questions
What are the best Shopify apps for ecommerce?
The best Shopify apps for ecommerce depend on your bottleneck. Klaviyo handles email and SMS marketing, Loox adds photo and video reviews, Gorgias manages customer support, ReConvert (now Upsell.com) boosts order value with upsells, and TinyIMG improves image speed and on-page SEO. Start with the one that fixes your biggest problem first.
How many Shopify apps should I install?
There’s no magic number, but most stores run well on two to five carefully chosen apps. Each one can add scripts, cost, and overlap with other tools. Install one app per clear problem, measure the result, and uninstall anything that isn’t earning its monthly fee or improving a number you track.
Are Shopify apps worth the cost?
They can be, when an app ties to a measurable result. An email platform that recovers abandoned carts or an upsell app that lifts order value can pay for itself. An app you rarely open won’t. Review each app’s results after 30 to 60 days and cancel whatever isn’t working.
What Shopify apps help increase sales?
Apps that target revenue gaps help most. Klaviyo supports abandoned cart and repeat-purchase messaging, Loox builds trust with customer photos, and ReConvert adds post-purchase offers. TinyIMG can also help by speeding up product pages. Pick based on where your store loses revenue today.
What Shopify apps are best for small businesses?
Small businesses should favor apps with free or low-cost starting tiers and quick setup. Klaviyo for email automation, TinyIMG for image optimization, and Loox for reviews cover the basics. Add Gorgias or an upsell app later, once ticket volume or order volume justifies the extra monthly cost.
Can Shopify apps slow down my store?
Yes. Many apps load JavaScript or widgets on your storefront, and each one adds weight. Review widgets, pop-ups, and chat tools are common culprits. Test page speed before and after installing an app, remove unused apps, and check your theme for leftover code after uninstalling.
Are Shopify apps safe to use?
Apps in the Shopify App Store go through Shopify’s review process, but you should still check permissions, read recent reviews, and skim the developer’s privacy policy before installing. Grant only the data access an app genuinely needs, and remove apps you no longer use so they don’t keep access to your store.
How do I choose the right Shopify app?
Start with the problem, not the feature list. Define the metric you want to improve, then compare two or three apps on pricing model, Shopify integration, support, and how easy they are to remove. Use free trials, read recent merchant reviews, and confirm the app won’t duplicate something you already have.
Final Verdict: Which Shopify App Should You Choose?
If you can fix only one thing this quarter, fix the bottleneck that’s costing you the most. For most stores that’s repeat purchases, which makes Klaviyo the best place to start.
Add Loox when product pages need proof, TinyIMG for speed and SEO basics, ReConvert when order volume is steady enough to test upsells, and Gorgias once support starts eating your day.
Bottom line: pick the app that solves today’s bottleneck, not the one with the longest feature list.
