The Shopify App Store has over 10,000 apps. Most of them are not worth installing. Some actively hurt your store by adding bloat, slowing page loads, and confusing customers with overlapping functionality. After testing dozens of apps across multiple stores, here are the ones that consistently drive measurable revenue increases in 2026 -- organized by function, with real pricing and honest assessments of each. If you are searching for the best Shopify apps to increase sales 2026, must-have Shopify apps for new stores, or the cheapest Shopify apps for ecommerce, this guide covers every category that moves the revenue needle.
One ground rule before we start: every app you install adds JavaScript to your storefront. Page speed matters for conversions. So the goal is not to install everything on this list -- it is to pick the best tool in each category that your store actually needs.
Email marketing remains the highest-ROI channel for Shopify stores. It is not glamorous, but abandoned cart flows, post-purchase sequences, and win-back campaigns generate revenue while you sleep. The two leaders in this space are Klaviyo and Omnisend, and choosing between them depends on your list size and budget.
Klaviyo is the gold standard for Shopify email marketing, and for good reason. Its Shopify integration is the deepest on the market -- it pulls in order data, browsing behavior, predicted lifetime value, and even back-in-stock events automatically. The segmentation engine is genuinely powerful: you can build segments like "customers who bought product X more than 90 days ago with a predicted next order date within 14 days" without writing any code.
Pricing: Free for up to 250 contacts (500 email sends/month). Paid plans start at $20/month for 251-500 contacts and scale with list size. At 10,000 contacts, expect to pay around $150/month. SMS is billed separately at roughly $0.01-0.02 per message. The pricing gets steep at scale, which is the main knock against Klaviyo.
Pros: Best-in-class segmentation, predictive analytics (CLV, churn risk), deep Shopify data sync, excellent flow builder, strong deliverability rates.
Cons: Expensive at scale compared to Omnisend. The interface has a learning curve. SMS pricing adds up fast if you are sending high volume.
Bottom line: If your list is above 5,000 contacts and you want to get serious about lifecycle marketing, Klaviyo is the tool to beat. Read our full Klaviyo review for a deeper breakdown.
Omnisend bundles email, SMS, and web push notifications into a single platform at a price point that undercuts Klaviyo significantly. For small-to-mid Shopify stores that want multichannel marketing without managing three separate tools, Omnisend is the smarter pick.
Pricing: Free plan includes 250 contacts, 500 emails/month, and 60 SMS. Standard plan starts at $16/month for 500 contacts (6,000 emails/month). Pro plan from $59/month adds unlimited emails and advanced reporting. At 10,000 contacts, Omnisend is roughly 30-40% cheaper than Klaviyo.
Pros: Lower price than Klaviyo at every tier, SMS and push included without separate billing, pre-built automation workflows that work well out of the box, clean interface.
Cons: Segmentation is not as granular as Klaviyo. Predictive analytics are more limited. Fewer third-party integrations. Not ideal for stores with complex multi-product catalogs.
Bottom line: For stores under $500k/year in revenue, Omnisend gives you 80% of Klaviyo's functionality at 60% of the cost. See our Omnisend review for the full comparison.
Customer support is not just a cost center -- it is a conversion tool. A visitor who has a question about sizing, shipping, or returns and gets an immediate answer is far more likely to buy than one who sends an email and waits 24 hours. The two best options for Shopify stores are Gorgias and Tidio, and they serve different segments.
Gorgias is purpose-built for ecommerce. It pulls in Shopify order data directly into support tickets, so your agents can see a customer's order history, tracking info, and subscription status without switching tabs. You can issue refunds, edit orders, and cancel subscriptions from within Gorgias itself. That deep integration saves real time.
Pricing: Starter plan at $10/month for 50 tickets. Basic at $60/month for 300 tickets. Pro at $360/month for 2,000 tickets. Enterprise pricing is custom. Overage tickets are billed at $0.40 each on the Basic plan. They also charge extra for automation add-ons.
Pros: Deep Shopify order integration, unified inbox (email + chat + social + SMS), macros and automation rules, revenue tracking on support interactions, self-service order portal.
Cons: Ticket-based pricing can get expensive during high-volume periods (Black Friday). The jump from Basic to Pro is steep. Some automation features require additional add-ons at extra cost.
Bottom line: If you process more than 100 support tickets per month and want a real helpdesk (not just chat), Gorgias is the standard. Read our Gorgias review.
Tidio gives you a live chat widget and basic chatbots for free. That is its killer feature. For a small Shopify store that cannot justify $60/month on Gorgias but still wants to answer customer questions in real time, Tidio is the right starting point.
Pricing: Free plan includes live chat for up to 50 conversations/month and basic chatbot flows. Communicator plan at $25/month per operator for unlimited live chat. Chatbots plan at $29/month for 40,000 chatbot triggers. Tidio+ (all features) starts at $394/month. The AI Lyro chatbot add-on costs $39/month for 50 conversations.
Pros: Generous free plan, easy to install and configure, decent chatbot builder, Shopify product cards in chat, visitor tracking.
Cons: Not a full helpdesk -- no ticket management, limited email integration, no order management. The AI chatbot (Lyro) is still basic compared to Gorgias's automation. Pricing jumps sharply once you outgrow the free tier.
Bottom line: Start with Tidio's free plan. When you outgrow it, migrate to Gorgias. See our Tidio review for the full picture.
Product reviews are one of the most reliable ways to increase conversion rates. Stores with visible reviews on product pages consistently see 10-15% higher conversion than those without. The key is automated collection -- you need an app that sends review request emails after delivery without manual effort.
Judge.me is the most popular review app on Shopify for a reason: it works, it is affordable, and it supports photo and video reviews. The free plan is genuinely useful -- not a crippled demo -- which is rare.
Pricing: Free plan (Forever Free) includes unlimited review requests, photo reviews, and a review widget. The Awesome plan at $15/month adds video reviews, custom forms, Q&A, Google Shopping integration, review carousels, and coupon incentives for reviewers.
Pros: Unlimited review requests on the free plan, supports 38 languages, fast load times (lightweight script), photo and video reviews, import reviews from AliExpress (useful for dropshippers), SEO-friendly review schema markup.
Cons: The free plan widget design is basic and limited in customization. The Awesome plan's $15/month is fair but adds up alongside other apps. No loyalty or referral features built in.
PageFly is a drag-and-drop page builder for Shopify that lets you create custom product pages, landing pages, and collection pages without coding. It is relevant here because well-designed landing pages for campaigns (ads, email promotions, product launches) convert significantly better than sending traffic to generic product pages.
Pricing: Free plan includes 1 published page. Pay As You Go at $24/month for 10 pages. Unlimited at $99/month for unlimited pages plus priority support. All plans include the full template library and page builder.
Pros: No coding required, responsive design controls, 100+ templates, integrates with most Shopify apps, fast customer support.
Cons: Adds page-builder JavaScript to your store. Complex pages can slow down load times. Some templates look dated. The free plan's 1-page limit makes it hard to test properly.
Upselling and cross-selling is the fastest way to increase average order value (AOV) without spending more on acquisition. The math is straightforward: if your AOV goes from $45 to $55, that is a 22% revenue increase from the same number of orders.
ReConvert turns your thank-you page into a revenue-generating upsell opportunity. After a customer completes checkout, ReConvert shows one-click upsell offers on the confirmation page. Because the customer has already committed to buying and entered payment info, the friction for adding another item is minimal. Stores using ReConvert report 5-15% of customers accepting a post-purchase upsell.
Pricing: Free for development stores. Basic at $4.99/month plus 0.75% of revenue generated by the app. Premium at $7.99/month plus 0.75%. Premium Pro at $14.99/month plus 0.75%. The revenue share means ReConvert only costs more when it is making you money, which is a fair model.
Pros: One-click upsells (no re-entering payment), customizable thank-you page builder, birthday collector, order tracking on thank-you page, A/B testing on offers.
Cons: The 0.75% revenue share adds up at scale. Only works post-purchase (no in-cart upsells). Requires some time to set up and test offers properly.
Privy specializes in converting visitors into subscribers and subscribers into customers. Its core strength is popups: exit-intent overlays, welcome discounts, spin-to-win wheels, and cart-saver displays. These are not sophisticated, but they work. The average Shopify store captures 3-5% of visitors' emails with a well-timed popup, and even a basic welcome flow converts 10-15% of those into first-time buyers.
Pricing: Free plan includes up to 100 mailable contacts. Starter at $30/month for up to 1,500 contacts (email only). Growth at $45/month for up to 2,000 contacts (email + SMS + conversion tools). The pricing tiers scale with contact count and can get expensive relative to dedicated email tools like Omnisend.
Pros: Easy to set up (no coding), effective popup templates, integrates with Klaviyo and Omnisend for passing captured emails, A/B testing on popups, free shipping bar.
Cons: The email marketing features are basic compared to Klaviyo or Omnisend -- use Privy for capture and a dedicated tool for email sequences. Pricing is high relative to what you get at scale. The spin-to-win wheel can feel gimmicky on premium brands.
A few popular apps that we tested but do not recommend for most stores:
New store (under $10k/month): Omnisend (free), Tidio (free), Judge.me (free). Total cost: $0/month. This covers email marketing, live chat, and review collection -- the three highest-impact functions.
Growing store ($10k-$50k/month): Klaviyo ($45-100/month), Gorgias Basic ($60/month), Judge.me Awesome ($15/month), ReConvert Basic ($4.99/month + revenue share), Privy Starter ($30/month). Total cost: ~$155-210/month.
Scaling store ($50k+/month): Klaviyo ($150-300/month), Gorgias Pro ($360/month), Judge.me Awesome ($15/month), ReConvert Premium Pro ($14.99/month + revenue share), PageFly ($24-99/month). Total cost: ~$565-790/month. At this level, also consider AI-powered tools for product descriptions, ad creative, and customer service automation.

Install an app, give it 30 days, then ask one question: did it generate more revenue than it cost? For paid apps, the math should be clear. For free apps, ask whether it saved you meaningful time or improved a metric you care about (conversion rate, AOV, email subscribers). If the answer is no, uninstall it. Shopify stores that ruthlessly prune their app stack consistently outperform stores that accumulate apps "just in case."
Check your store speed in Google PageSpeed Insights before and after installing any app. If an app drops your mobile score by more than 5 points, it is probably not worth the trade-off unless the revenue impact is substantial.
