Rebuy Engine Review: Who is It For? 

Rebuy is suitable for Shopify and Shopify Plus stores of all shapes and sizes. Whether you’re just setting up your store or running an established online enterprise with thousands of orders a month, Rebuy’s personalization engine can help any merchant to boost their conversions, LTV, and AOV.

Rebuy Engine Review: 3 Things I Love About It 

There’s a lot to admire about Rebuy Engine, but if I had to pick my favorites, the following would be in my top three.

  • Smart Cart: Rebuy’s trademarked Smart Cart technology is a rare blessing for merchants. Besides being fully customizable, it helps your store effortlessly push subscription reactivation, discount codes, product bundles, and more right from within the cart.

    AI-based product recommendations based on customer behavior data are a great way to increase cart size at checkout since customers would have a higher chance to buy them at that point. But Rebuy’s product bundling at checkout certainly takes the cake with selecting product size and variations within the bundle right from the cart page.

    If you want to push certain SKUs or clear out inventory, you can add your own set of rules or datasets to the Smart Cart recommendations on top of the automated AI-based option.

    Lastly, what I loved about the Smart Cart is the inclusion of even more conversion and AOV driving tools like Gift-with-purchase, one-click subscriptions, timed checkout offers, and more— all offered to customers without needing to leave the cart or checkout page.
  • Hyper-Personalization: At its core, Rebuy is a fully customizable Personalization Engine, and its hyper-personalization features are something I admire. Besides customer-precise UX customization across multiple channels, Rebuy’s predictive AI and ML technology closely study each customer’s behavior and shopping history to produce personalized recommendations and bundle offers.

    Paired with AI-driven upsells and cross-sells across key customer decision points, Rebuy certainly has data-driven measures to boost your AOV, LTV, and conversion rates.
  • Automated Retention: Another aspect of Rebuy that I found particularly helpful would be the option to automate Retention and Repeat Sales activities. With abandoned cart rates as high as 69.8% for eCommerce, abandoned carts are every online seller’s nightmare.
    But Rebuy takes some of the worries off your mind with its automated cart abandonment and post-purchase follow-up email. Besides, the app encourages repurchases with its automated reorder flows and pre-filled checkouts, making it more convenient for customers to make repeat purchases from your store.

There’s little not to like about Rebuy. But if I had to pick something I wished Rebuy did differently, I’d have to mention the lack of a free or freemium version. 

At a starting price of almost $100 a month, cheaper alternatives are easily available. But despite the slightly expensive subscription plans, considering the vast array of features Rebuy offers, you’d be hard-pressed to find a single tool that does it all.

Final Verdict 

Despite being a new player on the market, Rebuy Engine has managed to accomplish and offer a lot. From intelligent cart technology to predictive AI-driven product recommendations, Rebuy equips you with all the tools you need to increase AOV and conversions, resulting in better ROI for your business. Despite the slightly expensive subscriptions, Rebuy is a powerful tool with many impressive features that are worth trying.
