How to Find Shopify Stores by App [Sales Prospecting Guide]

TL;DR: Use a Shopify store database with app filtering to find stores using (or missing) specific apps. For individual stores, the free Store Inspector extension detects 72+ apps instantly. The best part: finding stores that are missing key apps like email marketing or reviews.

---

Finding Shopify stores is easy. Finding the right ones is harder. The ones that actually need what you're selling.

The difference? Filtering by the apps they use.

A store on Mailchimp but not Klaviyo is a chance to switch them over. A store running Meta Pixel but no email marketing app is leaving money on the table. A store using ReCharge already gets subscriptions.

This guide shows you how to find Shopify stores by app. More importantly, how to find stores that are missing key apps.

How to Find Shopify Stores by App (Overview)

Generic store lists don't convert. Filtering by apps does.

This is how agencies and app developers build prospect lists that actually convert. You're not just finding stores. You're finding stores with specific gaps.

The data: We looked at 513 Shopify stores. Stores with 1M+ monthly visitors average 4.4 apps. Stores under 10k average 2.4 apps. The gap is where opportunity lives. See full analysis →

The Numbers: What Apps Shopify Stores Actually Use

Before you start prospecting, you need to understand what's normal. We looked at 513 Shopify stores across different sizes and categories. Here's what we found.

App Adoption by Category

The opportunity columns matter most. 28% of stores have no email app. 64% have no reviews. These aren't edge cases. They're massive markets.

Here's an example: we found a fashion store doing 35k monthly visitors, running Meta and Google ads, with a premium theme. Zero email marketing. They're paying to get customers and then letting them walk away. That's not unusual. It's common.

App Usage by Store Size

The pattern is clear: bigger stores use more apps.

Small stores haven't built their stack yet. Mid-size stores (10k-50k) are the sweet spot: enough traffic to have budget, but gaps in their tooling.

According to Shopify's own data, the average merchant uses multiple apps. But "average" hides a lot. The stores that grow fastest tend to invest in their tools early.

Method 1: Check Individual Stores (Free)

Need to verify what apps a specific store uses? Use a browser extension.

Time: ~5 seconds per store | Cost: Free

How It Works

1. Install Store Inspector (free Chrome extension)
2. Visit any Shopify store
3. Click the extension icon
4. See all detected apps, pixels, and theme

What you'll find:

Pro tip: Check 5-10 competitors before prospecting. You'll spot patterns: which apps are common in your target niche, and which are missing.

Limitations:

• One store at a time
• Manual process (doesn't scale)
• Best for verification, not bulk prospecting

Method 2: Use a Store Database with App Filtering

If you're doing this at scale, you'll want a database that lets you filter by apps.

Time: 5-10 minutes for a qualified list | Cost: $49-300/month

What to Look For

Not all databases are equal. Here's what matters:

Database Comparison

Our take: For Shopify-specific prospecting with verified contacts, a focused database beats massive generic ones. Quality over quantity.

Finding Stores USING a Specific App

Here's how to find stores that use a particular app. Why would you do this?

• App partnerships: Find stores using apps that work well with yours
• Case studies: Find successful users of a tool you want to feature
• Competitive research: See who's using your competitor's product
• Integration targets: Find stores whose tech stack matches yours

Step-by-Step Workflow

Example: Find stores using Klaviyo

1. Open your store database
2. Set filter: Technology → Includes → "Klaviyo"
3. Add qualifiers: Traffic > 10k, Category = Fashion
4. Export results with contact data

Example: Find stores using Klaviyo + Gorgias (sophisticated stack)

1. Technology → Includes → "Klaviyo"
2. AND Technology → Includes → "Gorgias"
3. Traffic > 50k (budget indicators)
4. Export and prioritize by traffic

Apps That Indicate Budget & Sophistication

What we've seen: Stores with 4+ apps from this list are almost always doing real revenue. Our data shows high-traffic stores average 4.4 apps.

---

Finding Stores NOT Using an App (The Money Section)

Most people stop at "find stores using X app." But the real opportunity is finding stores that don't use an app. Gaps are opportunities.

Why "Missing App" Filtering Works

Step-by-Step: Finding Stores Without Email Marketing

The pitch: "You're running Meta ads (we can see the pixel), but you have no email capture or flows. You're paying to acquire customers and then letting them leave."

How to find them:

1. Filter: Technology → Includes → "Meta Pixel"
2. AND Technology → Does NOT Include → "Klaviyo"
3. AND Technology → Does NOT Include → "Mailchimp"
4. AND Technology → Does NOT Include → "Omnisend"
5. Traffic > 10k (enough to have ad budget)

Result: Stores actively spending on acquisition but missing retention. Easy pitch.

High-Value "Missing App" Combinations

Real Numbers: The "No Email" Market

From our 143K-store email marketing study:

• 62% of all stores have no detectable email app
• Klaviyo leads at 24%, Mailchimp at 13.5%, Omnisend at 3.2%
• Stores with email apps have 51% higher lead scores than those without

That's tens of thousands of stores spending on ads but ignoring retention. If you sell email services, this is your market.

App Combinations That Signal Qualified Leads

Beyond single apps, combinations reveal sophistication level.

The "7-Figure Stack"

Stores with this combination are almost always doing significant revenue:

Finding them: Filter for stores with 3+ from this list. These have budget, understand tools, and are open to optimization.

Sample Prospecting Workflows

Workflow 1: Email Agency Finding Mailchimp-to-Klaviyo Opportunities

Goal: Find stores using Mailchimp that should switch to Klaviyo

Filters:

• Technology includes: Mailchimp
• Technology does NOT include: Klaviyo
• Traffic: 10k-100k
• Category: Fashion, Beauty, or Health

Outreach angle: "You're on Mailchimp. Most stores your size switch to Klaviyo because [specific feature]. We've helped 12 brands make this switch. Here's what changed for [example]..."

Workflow 2: Reviews Platform Finding Gaps

Goal: Find successful stores without reviews

Filters:

• Traffic: 50k+
• Technology does NOT include: Judge.me, Yotpo, Stamped, Loox
• Has: Meta Pixel (running ads)

Outreach angle: "You're driving 50k+ visitors monthly but have no review system. Stores with reviews see 15-20% higher conversion. Here's a 5-minute setup that's free to start..."

Workflow 3: App Developer Finding Complementary Users

Goal: Find stores using apps that pair well with yours

Filters:

• Technology includes: [Complementary app]
• Technology does NOT include: [Your app]
• Traffic: 20k+

Outreach angle: "I noticed you're using [complementary app]. Most stores pair it with [your app] because [specific integration benefit]..."

Tools Comparison: Which Database to Use

What we recommend:

• For agencies: Database with "not using" filters + verified contacts
• For app developers: Database with technology combination filters
• For occasional research: Free Chrome extension

What You Can (and Can't) Detect

Let's be honest about what works and what doesn't.

Detectable Apps

Most frontend apps leave signatures:

• Email/SMS widgets and scripts
• Review widgets
• Chat widgets
• Upsell/cross-sell modifications
• Analytics pixels
• Popup tools
• Page builders

Not Detectable

Backend-only apps don't show on the frontend:

• Inventory management
• Fulfillment/shipping
• Accounting
• Order management
• Private/custom apps

Honest note: App detection is ~70-80% accurate for frontend apps. Some apps load conditionally or remove signatures. Databases update weekly, so recent changes may not reflect immediately.

FAQ

Can I find stores using any Shopify app?

Most popular apps, yes. If an app loads JavaScript or widgets on the storefront, it can be detected. Backend apps (inventory, fulfillment) can't.

What's the best way to find stores NOT using an app?

Use a store database with negative filtering. StoreInspect lets you filter by "does not use [app]" to find gaps.

How accurate is app detection?

About 70-80% for frontend apps. Some apps are harder to detect (Triple Whale, some analytics tools). We only report what we can verify.

How often does tech stack data update?

Most databases update weekly. If a store just installed an app yesterday, it may not show immediately.

Is it legal to prospect stores based on their tech stack?

Yes. You're looking at publicly available information: the scripts and tools that load in anyone's browser. For email outreach, follow CAN-SPAM (US) and GDPR (EU) rules.

What's better: finding stores WITH an app or WITHOUT?

Both have uses. "With" is good for partnerships and competitive research. "Without" is typically better for sales prospecting. Gaps are opportunities.

Which apps indicate the best prospects?

Stores with Klaviyo + Gorgias + one other premium app usually have budget. Stores with Meta Pixel but no email app are high-opportunity. They're spending on ads but missing retention.

---

Summary

Finding Shopify stores by app comes down to:

The key insight: 28% of Shopify stores have no email app. 64% have no reviews. These gaps are your market.

App combinations matter. A store with Klaviyo + Gorgias + Rebuy is sophisticated and has budget. A store with Meta Pixel but no email is spending to acquire and ignoring retention.
