Best Shopify Marketing Apps to Increase Sales & Conversions

There is a fact that Shopify is great at getting you live fast. But the core platform is intentionally “general purpose.” It will not automatically add the conversion pieces that most stores need to grow. Things like review widgets above the fold, spend thresholds that push bigger carts, loyalty points that pull customers back, or automated follow-ups when someone abandons checkout.

That gap shows up in the numbers. Baymard’s research puts the average cart abandonment rate at 70.19%, and the top reasons are very practical: extra costs feel too high (39%), trust concerns with card payment (19%), forced account creation (19%), and checkout feels too long or complicated (18%).

A Shopify marketing app is truly essential here when it directly fixes one of those leaks on your store, without a rebuild. For example, social proof apps reduce trust anxiety on the PDP. Promotion apps make the total feel worth it by adding a clear reward, like a free gift or a free shipping threshold. Email and SMS bring back the “almost buyers” you already paid to acquire.

Here are the core levers we use to increase sales and conversions:

1. Social proof & Product reviews
2. Sales promotion
3. Loyalty & Referrals
4. Email & SMS marketing
5. Paid advertising
6. Affiliate marketing

In this guide, we cover one standout Shopify app for each lever above, so you can choose based on the metric that is leaking right now.

#1 Rivyo Product Reviews (Social proof & Product reviews)

When customers visit your store for the first time, they often have doubts: "Does the product look like the photo?" "Is the quality worth the price?" Rivyo is not just a review collection tool. It is a comprehensive trust-building solution.

The app will assist you in eliminating psychological barriers to purchase by transforming actual customer reviews into visual social proof at key points of contact (Product Page, Collection Page, Google Shopping). Moreover, the integrated Q&A feature provides the answer to questions immediately, preventing customers from visiting other sites in search of the information.

Highlight features:

• Star ratings + review widgets (PDP/collection): Creates an anchoring effect by displaying ratings upfront, helping shoppers instantly spot trustworthy products without extra clicks.
• Photo/video reviews: Leverages user-generated content (UGC) to provide authentic visuals of size and fit, which are far more persuasive than studio photos.
• Q&A on product pages: Answers pre-purchase doubts directly on the page, removing the need for support chats and speeding up checkout decisions.
• Automated post-purchase review requests: Sends timed emails to collect fresh reviews automatically, ensuring a steady stream of social proof.
• Google Shopping stars/rich snippet support (plan-dependent): Displays star ratings in search results, boosting click-through rates (CTR) and attracting high-intent traffic.
• Star ratings + review widgets (PDP/collection): Provides an anchoring effect, showing the ratings above the fold. This has a beneficial effect of making shoppers see trustworthy products immediately and not requiring additional clicks.
• Photo/video reviews: Taps into user-generated content (UGC) to offer more believable images of size and fit, which are much more compelling than images in the studio.
• Q&A on product pages: The answer to the questions before the purchase is made on the page, and the product user does not need to have a chat with the support team and which saves time in making a decision.
• Automated post-purchase review requests: Automatically sends scheduled emails to get fresh reviews to maintain a constant flow of social proof.
• Rich snippet support/ Google Shopping stars (plan-dependent): Star ratings appear in search engines, which increases the click-through rate (CTR) and high-intent traffic.

Price (as of January 2026):

• Free plan: Free forever (Unlimited reviews, import 100 reviews).
• Paid plans: From $9/month (Unlimited imports, Q&A, Google Shopping integration).

Best for: Fashion, Beauty, and Dropshipping stores that need to build trust quickly. It is ideal for merchants moving from marketplaces (Amazon/AliExpress) who want to "port" their reputation to a new Shopify store to convert cold traffic immediately.

#2 BOGOS (Sales promotion)

Direct discounting is sometimes a double-edged sword as it can devalue your brand and thin your margins. BOGOS offers a smarter approach: adding value so customers voluntarily spend more.

This app specializes in complex Upsell & Cross-sell tactics that native Shopify discounts cannot handle. Instead of discounting, you give gifts, create combos, or bundle items, making customers feel they are getting a huge bargain, while you protect your profit and move inventory.

Highlight features:

• Auto-add free gift/gift popup: Automatically adds rewards at value thresholds (e.g., "Spend $50, get free socks"), motivating customers to add more items than planned.
• BOGO + Buy X Get Y (BXGY): Move slow-moving inventory with best-sellers (e.g., Buy dress, get hair clip free) to sell inventory and still appear valuable.
• Bundle builder + mix-and-match bundles: Enhances the shopping experience by allowing customers to make their own bundles (e.g., Pick any 3 and save 29), which will be persuasive in terms of purchasing in bulk.
• Volume discounts + tiered pricing: Uses logic such as Buy 2 get 10% off, and the customer will then compute the discount and purchase more.
• Upsell (Checkout + Thank-you page + FBT): Captures easy extra revenue by offering relevant add-ons when buyer intent is at its highest.

Price (as of January 2026):

• Free plan: Free for new stores (30 promotion orders/month).
• Paid plans: From $29.99/month to $99.99/month, unlocking unlimited orders and advanced bundle features.

Best for: Mid-sized Cosmetics, F&B, and Accessories brands struggling with low AOV. It fits perfectly for merchants who want to clear slow-moving inventory (dead stock) without damaging their brand image through deep discounts.

#3 Smile.io (Loyalty & Referrals)

As customer acquisition costs (CAC) continue to increase, it is 5 times less expensive to maintain old customers than new ones. Smile.io will enable you to turn one-time customers into long-term customers who make a return.

This application is not merely a point-gathering program. It is a customer-rewarding system of behavioral psychology: the more positive there is interaction with customers, the better it is rewarded and the more they feel connected and willing to become VIP to get perks. This is what is required to boost Customer Lifetime Value (LTV) in a sustainable manner.

Highlight features:

• Points + rewards: It makes customers have a sunk cost where they come back in order to redeem their points instead of throwing away their efforts.
• Tiers of the VIP: Promotes increased spending by encouraging customers to get higher levels of the benefits, such as free shipping or early access at higher levels.
• Referrals: Reward loyal customers to be low-cost acquisition sources by compensating them to acquire new and quality customers.
• Bonus events (2x points weekend): Makes demand high during bad times, but does not reduce the value of its products by direct discounting.
• Physical cues & rewards, loyalty space: Notifications to customers reminding them of their points and the closeness to the reward, which arises as an impulse purchase to achieve the target.
• Analytics + benchmarks: Measures redemption rates and LTV, which simply displays the amount of revenue generated by your loyalty program per dollar of investment.

Price (as of January 2026):

• Free plan: Free to install (200 orders/month, basic features).
• Paid plans: From $49/month to $999/month for VIP programs, deep analytics, and API access.

Best for: Supplies, Pet Supplies, and Skin Care brands with high repurchase of the product. It is urgent for the stores, which rely on community and word-of-mouth growth, where the cost of keeping a satisfied customer will be more profitable than spending money on Facebook in an effort to seek a new acquisition.

#4  Klaviyo (Email & SMS marketing)
