9 Best Shopify Customer Retention Apps (2026, Free & Paid)

The best Shopify customer retention apps are Klaviyo for email and SMS flows, Smile for loyalty points, and Recharge for subscriptions.

Fairing shows why customers buy, Rebuy brings them back with personalized offers, and WiserNotify shows live store activity that helps returning visitors buy again. Most stores start with one email app and one loyalty app.

Key takeaways

• Retention apps fall into five groups: email and SMS, loyalty, subscriptions, personalization, and feedback.
• Klaviyo, Smile, Fairing, Growave, and CWILL Loyalty all have a free tier on the Shopify App Store.
• Start with automated email flows, then add loyalty once you have repeat buyers to reward.
• Track your returning customer rate before and after you add an app to see if it works.

What Is Customer Retention on Shopify?

Customer retention is how many of your customers come back to buy again. On Shopify, the simplest measure is your returning customer rate, the share of customers who have ordered more than once.

To work out your retention rate for a period, use this formula:

Retention rate = (customers at the end − new customers) ÷ customers at the start × 100

For example, if you start the quarter with 1,000 customers, gain 300 new ones, and end with 1,100, your retention rate is (1,100 − 300) ÷ 1,000 × 100 = 80%.

Shopify’s Analytics reports show your returning customer rate, so you can check it before and after adding any app below.

The 9 Best Shopify Customer Retention Apps

1. WiserNotify

WiserNotify shows live sales, new reviews, visitor counts, and stock alerts on your store, which gives returning visitors a reason to trust you and buy again.

It doesn’t send emails or run a loyalty program, so it works best next to the apps below. See how sales popups in Shopify work.

• Recent sales popups: show who just bought, to reassure hesitant shoppers.
• Review notifications: surface fresh reviews while people browse.
• Urgency widgets: countdown timers, low-stock alerts, and free shipping bars, plus a sold counter for Shopify.
• A/B testing and goals: see which notifications lift conversions.

Pricing: on the Shopify App Store, a free tier covers 1,000 visitors a month, and paid tiers start at $5/month for 5,000 visitors. Plans on wisernotify.com start at $59/year with a 7-day free trial.

2. Klaviyo

Klaviyo is the email and SMS platform most Shopify brands use for retention. It syncs your store data, so welcome, abandoned cart, and win-back flows trigger on what each customer does.

Abandoned carts are one of the biggest retention leaks, as these cart abandonment statistics show.

• Automated flows: welcome, abandoned checkout, post-purchase, and win-back series.
• Segmentation: target customers by order history, spend, and behavior.
• Email, SMS, and WhatsApp: run every channel from one place.
• Product recommendations: personalized picks in every email.

Pricing: email is free for up to 250 contacts, SMS starts at $15/month for 1,250 credits, and paid email starts at $20/month for 251 to 500 contacts.

3. Smile

Smile is a loyalty app that rewards customers with points, referral bonuses, and VIP perks. It’s one of the most reviewed loyalty apps on the Shopify App Store and takes minutes to launch.

• Points program: 15+ ways to earn and redeem points.
• Referrals: reward customers who bring in friends.
• VIP tiers: give your best customers exclusive perks (Growth plan).
• Nudges: on-site reminders that show members their points.

Pricing: free for up to 200 orders a month; the first paid plan is $15/month for up to 500 orders, with a 14-day free trial.

4. Fairing

Fairing runs short surveys on your thank-you and order status pages. Asking “How did you hear about us?” or “Why did you buy?” shows which channels bring loyal customers and what makes them return.

• Post-purchase surveys: unlimited questions and responses.
• LTV analysis: compare survey answers against customer lifetime value.
• NPS surveys: track how likely customers are to recommend you.
• Integrations: send answers to Klaviyo, Meta, and 25+ other tools.

5. Growave

Growave bundles loyalty points, wishlists, referrals, and product reviews in one app. It suits stores that would rather manage one retention tool than several.

• Loyalty points: reward purchases and other actions.
• Wishlist: let shoppers save items and get alerts on price or stock.
• Referrals: referral program with fraud protection (Entry plan).
• VIP tiers and store credit: on the Growth plan.

Pricing: free for up to 200 orders a month; Entry is $15/month including 500 orders, then $20 per extra 100 orders.

6. CWILL Loyalty (formerly Loloyal)

CWILL Loyalty, previously called Loloyal, offers points, referrals, and VIP tiers at a lower entry price than most loyalty apps. It also integrates with Shopify POS for in-store rewards.

7. UpOrder (formerly Spently)

UpOrder, formerly Spently, turns Shopify’s order confirmation and shipping emails into branded emails with product recommendations. Customers open these emails more than any other, so they’re a natural place to drive the next order.

• Branded templates: for order, shipping, and account emails.
• Product recommendations: dynamic picks inside each email.
• Discount codes: add next-order offers to receipts.
• 25+ notifications: covers most emails Shopify sends.

Pricing: the first 25 orders a month are free, then $10 per additional 50 orders, with a 30-day free trial.

8. Rebuy

Rebuy uses AI to personalize product recommendations across your cart, checkout, and post-purchase pages. Its reorder landing pages make it easy for customers to buy the same items again. Pair it with these upsell and cross-sell strategies.

• Smart cart: a slide-out cart with personalized upsells.
• Post-purchase offers: one-click add-ons after checkout.
• Reorder pages: send customers straight to their past items.
• A/B testing: test offers and placements.

Pricing: from $25/month, scaling with your monthly orders.

9. Recharge

Recharge is the leading subscription app on Shopify. Subscriptions turn one-time buyers into repeat customers automatically, which makes it a strong fit for consumables like coffee, skincare, or pet food.

• Subscribe and save: offer subscriptions on product pages.
• Customer portal: subscribers skip, swap, or reschedule on their own.
• Cancellation prevention: offer alternatives when someone tries to cancel.
• Failed payment recovery: retry declined cards automatically.

How to Choose a Retention App

Pick based on the problem you need to solve first:

Your goal	App type	Apps to try
Bring first-time buyers back	Email and SMS flows	Klaviyo, UpOrder
Reward repeat buyers	Loyalty and referrals	Smile, Growave, CWILL Loyalty
Lock in regular orders	Subscriptions	Recharge
Raise order value on return visits	Personalization	Rebuy
Learn why customers stay or leave	Surveys	Fairing
Build trust on every visit	Social proof	WiserNotify

Before you install, check that the app works with your theme and the tools you already use, and that its price fits your order volume.

Reviews also bring customers back. Compare these Shopify product review apps if you don’t collect reviews yet.

Wrap Up

The right apps do most of the retention work for you. Start with automated emails, then add a loyalty program once you have repeat buyers.

If your products get used up, subscriptions lock in the next order.

Then watch your returning customer rate and keep the apps that move it.
