Best Shopify Apps For Growing Your Online Store (2026 Guide)
Best apps for Shopify
One of the biggest reasons Shopify continues to dominate ecommerce is its incredible app ecosystem. Whether you're launching your first online store or shipping thousands of orders each month, choosing the right apps can simplify everything from designing custom packaging to managing shipping and customer communication.
At CustomBoxes.io, we've tested dozens of Shopify apps over the years. Some became part of our everyday workflow, while others simply didn't provide enough value to justify another monthly subscription.
This guide shares the apps we've had the best experience with and explains where each one fits into a growing Shopify business.
Best Shipping App for Shopify: Intuitive Shipping
If there's one lesson we've learned while scaling CustomBoxes.io, it's that shipping can quickly become one of your largest expenses. This is especially true if you're shipping custom shipping boxes or products that vary in size and weight, where flat-rate shipping often doesn't reflect actual costs.
Many merchants start with Shopify's default shipping settings or flat-rate pricing. That works in the beginning, but as your catalog grows, so does the complexity of shipping products with different sizes, weights, destinations, and margins.
After implementing Intuitive Shipping, we were able to replace rigid shipping rules with flexible, real-time shipping logic that better reflected our actual costs.
Some of the capabilities we found most valuable include:
- Custom shipping rules
- Real-time carrier rates
- Product-specific shipping logic.Â
- Multi-package shipment support
- Checkout rate customization
- Better control over shipping profitability
The results were significant enough that Intuitive Shipping recently featured CustomBoxes.io in a customer success story, explaining how our shipping strategy evolved as we grew.

If your Shopify store ships products with different dimensions, weights, or packaging requirements, investing in a more flexible shipping platform may help improve both customer experience and shipping cost accuracy. Before choosing shipping rules, it's worth calculating your packaging costs using our Bulk Order Calculator to better understand how box quantities affect your overall shipping budget.
Best Email Marketing App: Klaviyo
If we could only recommend one marketing platform for Shopify, Klaviyo would be near the top of the list.
Rather than simply sending newsletters, Klaviyo helps automate the customer lifecycle through:
- Welcome series
- Abandoned cart recovery
- Browse abandonment
- Post-purchase follow-up
- Customer win-back campaigns
- Product recommendations
- Customer segmentation
The platform integrates extremely well with Shopify and provides much deeper customer insights than many traditional email platforms.
Other good options include:
- Omnisend
- Mailchimp
- Campaign Monitor
Best Page Builder
Your Shopify theme matters more than many people realize.
As your store grows, you'll likely want more flexibility than Shopify's native editor provides.
Our favorite page-building solutions include:
- PageFly
- Smart Themes
- Shogun
After switching our own theme, we experienced noticeable improvements in site speed, conversion rate, and SEO performance.
While every store is different, faster websites generally create a better shopping experience and can support stronger search performance.
Best Customer Support App: Gorgias
Excellent customer support becomes increasingly important as order volume grows.
Gorgias centralizes customer conversations from:
- Live chat
- Social media
- Shopify orders
More recently, AI-powered customer support has become much more capable. Depending on your needs, Shopify Inbox and newer AI assistants may also be worth evaluating.
Best Analytics Apps
Making decisions based on data is one of the fastest ways to improve an ecommerce business.
Some analytics tools we've found useful include:
- Google Analytics 4
- Conversific Profit Analytics
- Mixpanel
- Microsoft Clarity
- Shopify Analytics
Instead of simply measuring traffic, these tools can help identify:
- High-converting products
- Customer lifetime value
- Checkout drop-off
- Marketing ROI
- Visitor behavior
 Best SEO Apps
Organic traffic continues to be one of the most cost-effective customer acquisition channels.
Some useful Shopify SEO tools include:
- TinyIMG
- SearchPie SEO
- Schema Plus
- Judge.me (review schema)
- Ahrefs Webmaster Tools
No app replaces quality content, but the right SEO tools can help optimize technical elements that are easy to overlook.
Best Review App
Customer reviews build trust.
Our favorite review platforms include:
- Judge.me
- Loox
- Yotpo
Displaying authentic customer reviews can help increase buyer confidence and improve conversion rates.
Best Apps for Increasing Average Order Value
Growing revenue isn't always about attracting more visitors.
Sometimes it's about helping existing customers discover additional products.
Popular options include:
- Rebuy
- Bundler
- Frequently Bought Together
- Upsell & Cross Sell
Our Advice: Don't Install Too Many Apps
One mistake many new Shopify store owners make is installing dozens of apps immediately.
Every app adds complexity, and some can impact store performance or duplicate features that already exist within Shopify.
Instead, start with the essentials:
- Intuitive Shipping
- Klaviyo
- Gorgias
- PageFly
- Google Analytics
- Judge.me
Then add new tools only when there's a clear business need.
Final Thoughts
The Shopify App Store offers thousands of apps, but not every app will be a good fit for every business.
As your store grows, revisit your tech stack regularly and ask whether each app is helping improve operations, customer experience, or profitability.
For us at CustomBoxes.io, apps like Intuitive Shipping, Klaviyo, Gorgias, and our analytics tools have become core parts of our day-to-day operations because they solve real business challenges rather than simply adding new features.
Choosing a smaller number of well-integrated apps often creates a more scalable Shopify store than installing dozens of tools you'll rarely use.
