Best Shopify Apps for 2027: What to Install and What to Skip

If you sell on Shopify, or you run a Shopify store alongside an Amazon account, the app store is both your biggest lever and your easiest place to waste money. There are thousands of apps, most do one small job, and every extra app adds monthly cost and page weight. This guide covers the apps worth considering going into 2027, grouped by the job they do, with the pricing we could verify in October 2026. App pricing changes often, so treat every number here as a starting point and confirm it on the vendor's pricing page before you commit.

The short version: start with free or built-in tools, add a reviews app and an email platform, then add specialty apps only when a specific metric justifies them.

How to choose Shopify apps without bloating your store

Before you install anything, decide which number the app should move. Conversion rate, average order value, repeat purchase rate, or support cost per order. If you cannot name the metric, skip the app.

Three habits keep your stack healthy:

• Install one app per job. Two review apps or two popup tools fight each other and slow the storefront.
• Run a 30 day test. Note the baseline metric, install, and compare. Uninstall anything that does not clearly pay for itself.
• Check what the app leaves behind. Some apps leave code in your theme after removal. Clean it up or ask a developer to.

If you also sell on Amazon, keep your channels in sync. Our free Amazon seller tools cover fee and profit math that helps you decide which products deserve a Shopify push, and the Amazon sales calendar shows when to plan promotions across both channels.

Email and SMS marketing apps

Email is still the highest return channel for most stores because you own the list.

Klaviyo

Klaviyo is the default choice for stores that want deep segmentation and flows tied to purchase behavior. Per a 2026 roundup from ecomm.design, it offers a free plan for up to 250 contacts, with paid plans starting around $20 per month at 500 contacts. Pricing scales with your contact count, so it gets expensive as your list grows. Best for stores with a growing catalog and a team that will actually build flows.

Omnisend

Omnisend covers email, SMS and push in one tool. The same roundup lists a free plan up to 250 contacts and paid plans from roughly $16 per month at 500 contacts. It is a reasonable choice if you want a simpler interface and multichannel messaging without a steep learning curve.

Shopify Email

Shopify's own email tool is the cheapest place to start. The roundup lists 10,000 emails per month included and $1 per additional 1,000 emails. It lacks the segmentation depth of Klaviyo, but for a new store it is enough to send campaigns and a welcome flow.

Reviews and social proof apps

Reviews are the closest thing to a free conversion boost, and Amazon sellers already know this. If your products have strong Amazon reviews, you can reuse that social proof ethically by asking Shopify buyers for their own reviews rather than copying Amazon text, which breaks Amazon's rules.

Judge.me

Judge.me is the usual pick for stores that want reviews without a big bill. It has a free plan and a paid tier listed at $15 per month in the 2026 roundup. Check what the free plan includes before you rely on photo reviews or Google review snippets.

Loox

Loox focuses on photo and video reviews and is listed from $9.99 per month with no free plan. It suits visual products where customer photos sell better than text.

Customer support and chat apps

Support cost grows with order volume, so this is where AI tools pay back fastest. We cover this category in more depth in our guide to the best AI chatbot for ecommerce.

Shopify Inbox

Shopify Inbox is the free built-in chat for storefront conversations. For stores with low ticket volume, it is the right first step before paying for a helpdesk.

Gorgias and Tidio

Gorgias is a Shopify-first helpdesk that bills by ticket volume. Tidio combines live chat and a chatbot and bills by conversations. Published prices differ between sources and change often, and both charge extra when you exceed plan limits, so model your monthly ticket or conversation count against the vendor's current pricing page before choosing.

Automation and operations apps

Shopify Flow

Shopify Flow is the free automation builder that comes with Shopify plans. It handles rules such as tagging high value customers, flagging risky orders, and alerting you when inventory drops. The 2026 roundup notes that Shopify Plus unlocks additional triggers and actions. For most stores, Flow replaces several small paid apps, so look here first.

Subscriptions, loyalty and upsells

Recharge handles subscriptions (the roundup lists a Pro tier at $99 per month plus transaction fees), Smile.io handles loyalty (listed from $49 per month), and ReConvert, now branded Upsell.com, handles post purchase upsell pages (listed from $4.99 per month plus a commission on extra revenue). Add these only when you have repeat purchase data that supports them. A subscription app makes sense for consumables, not for one time purchases.

Analytics and attribution apps

Triple Whale is listed at $129 per month in the roundup and targets stores spending meaningfully on paid ads. If your ad spend is small, Shopify's built-in analytics plus your ad platform dashboards are enough. Do not pay for attribution before you have budget worth attributing.

A simple starter stack for 2027

For a store under a few thousand orders per month, this stack covers most needs:

1. Shopify Flow for automation (free)
2. Judge.me for reviews
3. Klaviyo or Omnisend for email and SMS
4. Shopify Inbox for chat, upgrade to a helpdesk when tickets pile up
5. One upsell or subscription app, only if your data supports it

Review the stack every quarter. Anything that cannot show a metric lift gets removed.

The GTM angle

If you sell services or software to Shopify and Amazon merchants, the app stack is a targeting signal you can use in outbound. Tools like BuiltWith and similar technology lookups show which stores run Klaviyo, Gorgias, Recharge or none of the above. That tells you who to contact and what to say.

A few concrete plays:

• Trigger-based email. A store that just installed a subscription app is probably planning retention. Pitch a lifecycle email audit, not a generic agency intro.
• ICP segmentation. Split lists by stack. A Klaviyo store with no reviews app has a different problem from a store with no email platform at all.
• Offer design. Lead with a small paid or free deliverable, such as a flow teardown or a support cost review, rather than a call request.
• Partner angle. If you build or resell an app, pitch agencies and freelancers who install apps for clients.

Before you scale any of this, estimate the return with the cold email ROI calculator. Use the AI tools directory to find tools for list building and enrichment, and see our Amazon seller newsletter for the audience side of this market.

Frequently Asked Questions

What are the best Shopify apps for a new store?

Start with Shopify Flow for automation, Judge.me for reviews, Shopify Email or Klaviyo for email, and Shopify Inbox for chat. All have free entry points, so you can test before spending.

How many Shopify apps is too many?

There is no fixed number, but each app adds cost and code to your storefront. If you cannot name the metric an app improves, remove it. Audit your stack every quarter.

Are free Shopify apps good enough?

For early stage stores, often yes. Shopify Flow, Shopify Email and Shopify Inbox are free, and several third party apps offer free tiers. Upgrade when you hit contact, order or ticket limits.

Do Shopify apps slow down my store?

Some do, especially those that load scripts on every page. Test page speed before and after installing, and remove apps you no longer use.

Can I use Shopify apps if I mainly sell on Amazon?

Yes. Many Amazon sellers add a Shopify store to own their customer list. Email, reviews and loyalty apps help you build repeat sales that Amazon does not give you.
